1 Introduction

Entrepreneurs and new firms are widely recognized as important contributors to economic growth and job creation, as evidenced by various studies (e.g., Audresch, 2007; Agihon et al., 2009; Baumol, 1968; Carree & Thurik, 2010; Haltiwanger et al., 2013; Urbano et al., 2019). However, economic downturns, such as the Great Recession, have a significant impact on their operations (e.g., Asturias et al., 2023; Dinlersoz et al., 2021; Fairlie, 2013; Gourio et al., 2016; Siemer, 2019). The COVID-19 pandemic has had a particularly negative impact on new firms, which are more vulnerable than established businesses. Consequently, the number of new business entries has significantly decreased during the early stages of the pandemic (e.g., Asturias et al., 2023; Dinlersoz et al., 2021; Sedlácek & Sterk 2020). To address this issue, many governments have implemented various forms of support for the affected businesses (OECD, 2020; Kuckertz & Brändle, 2022). It is important to analyze the impact of these support measures by considering how to assist new firms during economic recessions. In this study, we examine how the Japanese government’s support for new entries in the restaurant industry affected their behavior during the early stages of the COVID-19 pandemic.

The COVID-19 pandemic and the subsequent lockdown policies severely affected the service industry, including restaurants. Early surveys conducted in the USA by Bartik et al. (2020) reveal that this industry is particularly vulnerable to prolonged economic shocks. In the UK, Barrero et al. (2020) also show that sectors requiring face-to-face service have shrunk. In 2020, the total sales of the restaurant industry in the USA were $240 billion less than those estimated using pre-pandemic data for 2020 (National Restaurant Association, 2021). Japan also experienced a significant decline in household spending on eating out by 60% from April to May 2020 compared to that in the same period in 2019.Footnote 1 This is because the government asked people to limit their mobility from March 2020 onward to reduce contact with each other.Footnote 2 The government also requested that dine-in restaurants suspend overnight operations and reduce their business hours due to the risk of face-to-face contact increasing the rate of infection.Footnote 3 In view of implementing such a strict policy, the government decided to provide financial assistance to dine-in restaurants. This support policy started in April 2020 in Tokyo and other urban areas. Initially, the support amount was about JPY 25,000 (\(\approx \$228.5\)) per day.Footnote 4 From December 2020 to March 2021, the amount of financial support was increased to 2.5 times the initial amount. Our primary focus is on the latter policy change, as it provides financial assistance to new businesses that meet certain criteria as well as existing restaurants. This gives us a unique opportunity to investigate the impact of such a policy on new enterprises.

Moreover, there are a few advantages of studying the policy impact on new firms. First, the policy was not specifically designed for new firms but to help existing restaurants. However, due to the urgent need for relief, the government provided financial aid to all businesses, regardless of their past performance. This resulted in potential new firms benefiting from this policy, which was an unexpected boost for them. After all, this is an entirely exogenous shock for these new firms and serves as a fascinating case study on the effects of financial aid on new businesses. Second, since every firm that suspended their overnight operations or shortened their business hours could receive support, this policy did not include any signaling effect. Government subsidy policies for new firms often involve screening, and recipients obtain subsidies, which signals that they are superior companies (Howell, 2017). Therefore, it is difficult to separate the impact of financial support from signaling firm performance. Finally, identifying the impact of such a specific policy is always challenging due to the government implementing various measures for small and medium-sized enterprises (SMEs) and self-employment. However, we can employ a difference-in-differences (DID) model because financial support for dine-in restaurants to compensate for their business hour restrictions was implemented separately by local governments, making it easier to identify its effects.

We gathered data from administrative records covering newly approved restaurants as well as discontinued businesses in Japan. In accordance with the Food Sanitation Act, all restaurant owners must receive permission from a local public health center before opening and submit a notification of discontinuation before closing. We sourced these records by visiting each local government’s website or requesting the data’s release based on the Information Disclosure Ordinance. Our dataset comprised lists of restaurants that entered and exited before and during the COVID-19 outbreak. This allowed us to investigate changes in the number of entries and exits in the restaurant industry before and during the pandemic. Further, since our dataset encompasses all types of restaurants (dine-in and others) and multiple regions (with or without financial support), we used a DID model by business type and region to evaluate the causal effect of the financial support on dine-in restaurant entries and exits.

The findings are as follows. Our estimation results indicate that the expansion of financial support from December 2020 to March 2021 increased the number of dine-in restaurant openings and decreased the number of closings. Throughout fiscal year 2020 (FY2020), as compared to that in the pre-pandemic period, the number of restaurant openings remained consistent while the number of restaurant closings decreased. However, the results also indicate that the extent of the impact of the expansion was greater in areas with lower opening and operating costs, while it did not vary based on an index anticipating potential sales, which could have supported relatively low-productive firms or firms whose objective was to obtain the financial support. In addition, during the period when financial support expanded, among the dine-in restaurants that did exit, the proportion of those leaving within 1 year decreased substantially.

Our findings align strongly with previous studies that have highlighted the limitations of universal government aid for new firms in terms of economic performance (e.g., Branstetter et al., 2014; De Meza, 2002; Santarelli & Vivarelli2002). For instance, Branstetter et al. (2014) find that, although a regulatory reform reducing firm entry costs led to an increase in firm entries and employment in Portugal, most of these firms were “marginal firms” unlikely to survive the first 2 years. Shane (2009) also argues against indiscriminately supporting new entrants based on extensive previous study surveys. Our results support the view that, even during severe recessions such as the COVID-19 pandemic, governments should selectively support new firms. Therefore, policymakers need to reconsider support schemes for new firms during a recession. Further, previous studies also investigate the impact of government support programs on incumbent SMEs during the COVID-19 recession. Such support programs include subsidies, public credit guarantees, and emergency loans (e.g., Belitski et al., 2022; OECD, 2021; Honda et al., 2023; Liu et al., 2022; Pedauga et al., 2022; Yamori and Aizawa, 2021. Some studies have found that these programs have prevented exits of low-productive firms from the market (e.g., Belghitar et al., 2022; Block et al., 2022; Dörr et al., 2022; Honda et al., 2023; Hoshi et al., 2023; Morikawa, 2021; Muzi et al., 2023). Our findings support these previous studies, highlighting the importance of selective support by the government in keeping superior SMEs afloat during challenging economic times.

The remainder of this paper is organized as follows: Section 2 describes the government support for the restaurant industry; Sections 3 and 4 explain our data and estimation strategy, respectively; Section 5 presents the results; and finally, Sections 6 and 7 discuss the results and conclude the paper, respectively.

2 Institutional background

2.1 COVID-19 and government policies in the early pandemic period in Japan

In Japan, where the first confirmed COVID-19 case was reported in January 2020, in the earliest pandemic period, the increase in the number of cases was moderate, except for the cluster on the cruise ship Diamond Princess. As such, there was little impact on economic activities, at least until the end of February. In March 2020, the government asked people to stay at home and closed public schools. The first wave of the pandemic lasted from the end of March 2020 to May 2020 (Fig. 1).Footnote 5 To tackle the first wave, the first declaration of a state of emergency, as a request for people to voluntarily refrain from going out, was issued in April 2020. Around the same time, the local governments also asked a wide range of industries to refrain from business activities in Tokyo and other urban areas.

Notes: The expenditure per household for two or more person households is used. To control for month-level seasonality, we regressed the eating-out expenses on month fixed effects and used the sum of residuals and the constant term as a seasonally adjusted eating-out expense. The average monthly seasonally adjusted expense per household through January 2020 is JPY 13,865. The solid and dashed vertical lines indicate February 2020 and January 2021

As the restaurant industry has been one of the industries significantly affected by the pandemic, government policies aimed at combating this impact since the onset of the first wave. Frequent infection clusters were observed at dine-in restaurants that served alcoholic beverages at night. As a result, restrictions on operating hours in dine-in restaurants were intermittently enforced. In addition, local governments encouraged people to avoid going out until the start of a campaign aimed at preventing cluster outbreaks. These restrictions and people’s associated behaviors reduced the demand for restaurants in 2020. The expenses for eating out decreased after March 2020, reaching a decrease of around 56% compared to the average value from January 2016 to January 2020 in April 2020, and reached only the pre-pandemic level in March 2023 (Fig. 2).Footnote 6 After the end of the first wave, local governments did not request business hours restrictions for dine-in restaurants until the end of 2020, except in Tokyo.Footnote 7

Some local governments provided financial support for dine-in restaurants to compensate for the loss of revenue due to the restrictions on operating hours during the early pandemic period.Footnote 8 During the earliest COVID-19 pandemic period, for instance, the Tokyo metropolitan government provided financial support for dine-in restaurants in response to the requirement of operating hour restrictions during the first wave (from the end of March 2020 to May 2020) and the second wave (from July 2020 to August 2020) of the pandemic. Similarly, Kanagawa Prefecture and Osaka Prefecture provided support during the first wave.

The central government of Japan provided financial assistance for SMEs and self-employed individuals operating before the pandemic, or incumbents, including running dine-in restaurants, through programs such as the Business Continuity Grant (jizokuka kyufukin) and the Office Rent Grant (yachin shien kyufukin).Footnote 9 Unlike these programs, the dine-in restaurants established after the onset of the pandemic could also apply for financial support aiming to compensate for the business hour restrictions. For example, in Tokyo, dine-in restaurants could apply for financial support as long as they started their business before the nighttime business restrictions were enforced.Footnote 10

Changes in the amount of financial support per day (JPY 1000). Notes: These figures summarize the amount of financial support per day for a dine-in restaurant that fully cooperated with the request by local governments to reduce business hours. Note that whether a restaurant could receive financial support depended on the address where the restaurant was located, even within the same prefecture. The first black line indicates December 14, 2020, when the prime minister announced that the national government would support local governments to expand the financial support for reducing the business hours of dine-in restaurants. Additionally, on December 23, 2020, the subcommittee on novel coronavirus disease control recommended the national government to take measures regarding businesses, including restaurants reducing their business hours in Tokyo, while on December 25, 2020, the prime minister announced the request for restaurants to reduce their business hours and receive either financial support and/or face penalties. The second black line indicates January 8, 2021, when a state of emergency was declared in Tokyo, Kanagawa Prefecture, Chiba Prefecture, and Saitama Prefecture. In addition, on January 14, 2021, a state of emergency was declared for other seven prefectures, including Osaka and Fukuoka

The payments varied across periods and municipalities. Figure 3 summarizes the amount of financial support per day for a dine-in restaurant if the restaurant fully cooperated with the request of local governments to reduce its business hours in the six prefectures in which the second state of emergency was declared (Fig. 4).Footnote 11 Since whether a restaurant could receive financial support depended on various conditions, for simplicity, the figure shows an example of the changes in the amounts for a dine-in restaurant with eligibility for all requests. Figure 3a covers four regions where the second state of emergency was declared on January 7, 2021 (Tokyo, Saitama/Kawagoe, Chiba, and Yokohama/Kawasaki),Footnote 12 and Fig. 3b shows two regions in which the state of emergency was declared on January 14, 2021 (Sakai and Fukuoka Prefectures).Footnote 13 Figure 3 shows that the financial support for dine-in restaurants reducing their business hours before December 2020 in selected areas was characterized by small payment amounts and shorter periods. For instance, a restaurant in Tokyo could receive JPY 25,000 (\(\approx \$228.5\)) per day between April and May 2020 for reducing its business hours, and a restaurant in Osaka prefecture could receive JPY 31,250 (\(\approx \$285.7\)) per day from late April to early May.Footnote 14

Table 1 Financial support per month

It is important to note other policies for the restaurant industry in 2020. During a period of temporary decline in COVID-19 infections, to stimulate demand for dine-in restaurants, the governments started a subsidy scheme for people using dine-in restaurants called the “Go to Eat” campaign. The campaign did not cover takeout and delivery-only restaurants. Therefore, this may have affected only the number of dine-in restaurant entries and exits. However, with the increase in the number of new infections, the campaign was terminated within 1 or 2 months. For example, the Tokyo metropolitan government started the campaign on November 20 and suspended it on November 26, 2020.Footnote 15Footnote 16 The expenses for eating out recovered somewhat during the “Go to Eat” campaign (October to November 2020) (Fig. 2). In later sections, we discuss the campaign’s impact using descriptive statistics and estimations.

2.2 Expansion of financial support for dine-in restaurants after the end of 2020

The amount of financial support significantly increased after December 2020. For instance, in Tokyo, the amount per day between January and March 2021 was JPY 60,000, which was twice more than that between April and May 2020 and six times more than that between August and September 2020 (Fig. 3). In addition, the number of prefectures providing financial support increased among the six analyzed prefectures after December 2020 (Fig. 3). This is because, first, the number of new COVID-19 cases dramatically increased in December 2020 (Fig. 1). To reduce the rapid spread of infection, many municipalities started to ask dine-in restaurants to reduce their nighttime business hours, with financial support as compensation. Second, then Prime Minister Yoshihide Suga announced that the national government would financially support local governments in providing the compensation on December 14, 2020 (the first solid black line in the figure). Additionally, on December 23, 2020, the chair of the subcommittee on novel coronavirus disease control recommended the national government to take measures regarding businesses, including restaurants, to reduce their business hours in Tokyo (the second solid black line); 2 days after this recommendation, the then prime minister announced the legal basis for asking restaurants to reduce their business hours and obtain financial support and/or face penalties.

In practice, in all six prefectures, the amount of financial support for reducing nighttime business hours reached JPY 60,000 (\(\approx \$548.5\)) per day after the state of emergency was declared. In the case of Tokyo, dine-in restaurants reducing their business hours could obtain financial support up to JPY 1.72 million (\(\approx \$15,722\)) in January 2021 and JPY 5.06 million (\(\approx \$46,252\)) from January 2021 to March 2021 (Table 1). According to a Japanese survey, during the pre-pandemic period, approximately 75.4% of dine-in restaurants reported monthly sales below JPY 1.8 million (equivalent to the monthly financial support amount of JPY 60,000 per day). This suggests that the daily support amount of JPY 60,000 can be considered substantial compared to the sales in the pre-pandemic period.Footnote 17 Between January and March 2021, the financial support amount was the same in each prefecture. The opening and operating costs for dine-in restaurants can vary among municipalities within a prefecture, potentially creating a greater incentive to enter the market in areas with lower costs. In total, the budget for this support measure reached JPY 1 trillion (\(\approx \$9 billion\)) by January 2021.Footnote 18

After the second state of emergency was lifted, the financial support amount was revised from a uniform amount to one based on the daily sales of individual restaurants. For example, in Tokyo, between April 12 and May 11, 2022, the amount per day ranged between JPY 40,000 and JPY 100,000 based on the daily sales of individual restaurants. For restaurants with daily sales below JPY 100,000, the support amount per day was fixed at JPY 40,000.Footnote 19 According to survey data, during the pre-pandemic period, 81.2% of dine-in restaurants earned below JPY 100,000 per day.Footnote 20 For most restaurants, the daily financial support amount was reduced by 33.3% from the original daily amount of JPY 60,000 to JPY 40,000, which reduced the incentive to enter the market.

After December 2020, while financial support for dine-in restaurants to reduce business hours was expanded, penalties were also established for dine-in restaurants that did not comply the hour reduction requests. If a restaurant did not comply, the prefectural governor could issue an “order” for the reduction. If the restaurant did not comply with the “order,” the governor could impose a fine of up to JPY 300,000. Actually, the Tokyo Metropolitan Government notified the court to impose fines on four restaurants that refused to comply with the “orders” to reduce their business hours during the second state of emergency declaration from January to March 2021, and the court imposed fines of JPY 250,000 on each.Footnote 21 In sum, restaurants that did not follow the request faced monetary penalties, making it difficult for them not to accept the request. According to a survey conducted in the middle of January 2021, approximately 96.5% of restaurants responded that they would comply with the business hour reduction.Footnote 22

3 Data

To investigate restaurant entries and exits during the pandemic, we used administrative data on newly approved licenses and the discontinuation of businesses in the food industry. In Japan, all food businesses, including restaurants, retail food businesses, and food manufacturers, need to obtain permission from the public health center of the local government. We used the list of these permissions, including information on business names, addresses, permission dates, types of businesses, types of applications (new or renewals), and closing dates.Footnote 23 We collected data in two ways: downloading them from the local government’s website or asking each local government to provide data based on the Information Disclosure Ordinance. As many local governments did not publish the lists on their websites, we had to ask them for the data. We mainly focused on Tokyo and Kanagawa Prefecture, which declared a second state of emergency. Among the prefectures that declared the second state of emergency, Tokyo and Kanagawa Prefecture covered 45.5% of dine-in restaurants (in 2019)Footnote 24 and 33.1% population (in 2020)Footnote 25

Table 2 summarizes the departments in charge of food businesses, types of data available, and available years. Overall, we obtained data on restaurants opening from 84 municipalities and on restaurants closing from 39 municipalities. Features of the data such as the years in which the data are available and format differed across departments in charge. For example, the data on Toshima were provided in hard-copy format, and we utilized the OCR software to convert them to a more manageable format. The notes to Table 2 explain the data features. Figure 5 shows the available municipalities in the Tokyo metropolitan area. The darker colored areas indicate the municipalities for which data on newly approved for food businesses are available. For Tokyo and Kanagawa Prefecture, data for around 76.8% (73 of 95) of municipalities are available. In addition, we collected data on six large cities in the prefectures that declared a second state of emergency (Saitama, Kawagoe, Chiba, Sakai, Kitakyushu, and Kurume) and three large cities in the prefectures that did not declare the second state of emergency (Shizuoka, Hamamatsu, and Okayama). For some municipalities, data on the discontinuation of food businesses are available, and we used them in the analysis. It is possible that some restaurants did not submit a notification of discontinuation, resulting in under-reporting.

The municipalities can be divided into three groups: the first group under the second declaration of state of emergency from January 7, 2021 (Tokyo, Kanagawa Prefecture, Saitama, and Chiba), the second group from January 14, 2021 (Sakai, Kitakyushu, and Kurume), and the third group not under the second declaration of a state of emergency (Shizuoka, Hamamatsu, and Okayama). Since the municipalities in the last group have similar population composition, we utilize them as the control group.Footnote 26

Table 3 Brief data description

In Table 3, the number of newly opened restaurants in the sample is above 20,000, and the restaurants that have gone out of business are around 12,000 in both FY2019 and FY2020.Footnote 27 The numbers in FY2020 are comparable to those in FY2019, despite the COVID-19 pandemic: a decrease of 3% and an increase of 1.7% for new approvals and discontinuations, respectively.

As explained in Section 2, the financial support for reducing business hours was only for dine-in restaurants; as such, we categorized the sample by business type. We utilized the information on types of approved businesses to classify food businesses into dine-in restaurants, other types of restaurants, including those serving foods only for takeout and for delivery and convenience stores.Footnote 28 All dine-in restaurants were eligible to apply for support in the prefectures providing support programs while takeout restaurants, delivery chains, or convenience stores were not. Therefore, we focus on two groups: dine-in restaurants as the treatment group and other types of restaurants as the control group.

We constructed a municipality-restaurant type level monthly dataset to identify the effects of the financial support for reducing business hours on the number of newly approved dine-in restaurants. Namely, we aggregated the number of newly approved restaurants by the municipality and restaurant type (dine-in/other types) for each month of FY2019 and FY2020 for which data are available for all municipalities. We considered the municipalities with at least one approved restaurant for both dine-in and other types in the two fiscal years; two villages in Tokyo, To-shima and Mikurajima, were excluded from the analysis. The number of observations is 3936 (82 municipalities \(\times \) 2 types \(\times \) 24 time periods). In the same manner, we also constructed the municipality-restaurant type level monthly dataset for restaurant closings, and the number of observations is 1872 (39 municipalities \(\times \) 2 types \(\times \) 24 time periods).

Table 4 Summary statistics

3.1 Descriptive statistics

This section presents the descriptive statistics of municipality-wise restaurant types in terms of market entries and exits during each month of the COVID-19 pandemic. Table 4 shows the average monthly number of newly approved restaurants and that of restaurants that have gone out of business, as well as the proportion of non-zero observations for those numbers. According to Table 4, on average, around 11 restaurants obtained business approval per month, and around 70% of observations had at least one newly approved restaurant. Over the sample period, on average, around 13 restaurants went out of business. The number of dine-in restaurants with new business licenses is on average approximately 2.6 times more than that of other types of restaurants, and the same tendency is observed for restaurant closings. The average number of newly approved restaurants and that of restaurants that have gone out of business in FY2020 are almost the same as those in FY2019 (columns 2 versus 3), implying that new restaurant openings did not decrease and the closing of existing ones did not increase, despite the COVID-19 pandemic decreasing the demand in the restaurant industry.

Fig. 6
figure 6

Number of dine-in restaurants entering and exiting the market in FY 2020 compared to the same months in the previous year by category. Note: We calculate the number of newly approved dine-in restaurants

The differences in the number of market entries and exits before and during the pandemic may be heterogeneous by month because the number of COVID-19 cases and the government’s response to it changed dramatically every month. Figure 6 shows the number of newly approved dine-in restaurants in FY2020 (panel a) and that of dine-in restaurants that went out of business (panel b) compared to the same months in the previous year by category: April and May, November, December to next March, and other months. In FY2020, the first financial support for restaurants to reduce their business hours was provided in April and May, the Go To Eat campaign was held in November, and financial support was expanded from December to the next March. In other months, there were few support programs for dine-in restaurants.

According to Fig. 6a, the number of newly approved dine-in restaurants was comparable with that in the same months of the previous year for April and May (1.06 times more). The number of newly approved dine-in restaurants from December to next March, when the financial support expanded to other prefectures and included larger amounts, was approximately 1.24 times more than that in the same months in the previous year despite all prefectures facing the highest number of new COVID-19 positive cases in FY2020. The number of newly approved dine-in restaurants in November, when the Go To Eat campaign was held, was around 80% of that in the previous November; in other months, the number of newly approved dine-in restaurants in FY2020 was smaller than that in the same months in FY2019. The result suggests that the financial support for dine-in restaurants to reduce their business hours offsets the decrease in entries due to the pandemic, and the larger amount of financial support from December to next March had an important role in promoting new entrants.

The number of restaurants that went out of business during the months with support programs was below that in the previous year (from right to left, 88.3%, 88.6%, and 96.4%) (panel b). In other months, the restaurant closings in FY2020 were 120% more than those in FY2019. Unlike restaurant openings, the number of restaurant closings might have been affected by the Go To Eat campaign. As the campaign aimed to encourage people to eat at dine-in restaurants and the restaurants could get a subsidy as well, the campaign might have prevented the restaurants that wanted to continue businesses from closing, but it did not promote restaurant openings for the subsidy only.

While the descriptive statistics suggest that supportive measures, particularly the expansion of financial support for dine-in restaurants reducing their business hours, affected restaurant openings and closings, we cannot rule out other factors that influenced restaurant openings and closings. For example, there were other government policies for all firms. Further, it is possible that after December 2020, the promotion of entries and the suppression of exits due to financial support were offset by the significant increase in the number of COVID-19 cases. To evaluate the impact of the expansion of financial support more accurately, we employ an event study and DID models.

4 Estimation

While there is an increase in the number of newly approved restaurants and a decrease in the number of closing restaurants after the announcement of the larger financial support amount, it is difficult to conclude that those are due to the expansion of financial support for dine-in restaurants. For example, it is possible that more people were working from home due to the pandemic, thus the demand for food businesses was higher in residential areas. It is thus necessary to construct a control group for the changes in the number of newly approved dine-in restaurants in the treated area to identify the causal effects of the expansion of financial support on restaurant openings/closings.

The basic idea for estimating the effect of the expansion of financial support for restaurants is to compare the changes in the number of newly approved or closing dine-in restaurants with those in the number of other types in the treated areas, that is, a DID approach with the former as the treatment group and the latter as the control group. Since local governments provided significant financial support only for dine-in restaurants, the expansion of financial support may have increased the number of dine-in restaurants but did not affect the number of other types of restaurants in the treated areas. Additionally, shocks such as the increase in new COVID-19 cases or the increase in the demand for food businesses affected the restaurant industry regardless of business type. The DID approach controls for shocks and identifies the effects of the expansion of financial support for dine-in restaurants.Footnote 29

One could argue that the shocks act heterogeneously by restaurant type. For example, the increase in demand for food businesses in residential areas may encourage entrepreneurs to open new takeout restaurants rather than dine-in ones because the latter may cost more to run. We add a cross-term between the one-period lagged term of new COVID-19 cases in the analyzed prefectures and a restaurant-type dummy to control for the heterogeneous response to shocks.Footnote 30 In addition to other types of restaurants in the areas with a declaration of a state of emergency, we use the number of restaurants (both dine-in and other types) in the area where there was no financial support during the sample period (Shizuoka, Hamamatsu, and Okayama) as the control group for the analysis on restaurant openings.Footnote 31Footnote 32

The estimation equation is as follows:

$$\begin{aligned} y_{mit} =&\beta _{0} + \beta _{1}T_{mi} + \beta _{2}After_{t} \nonumber \\&+ \beta _{3}After_{t}\times T_{mi} + x'_{mit}\gamma _{1} + \eta _{t} \nonumber \\&+ \phi _{mi} + u_{mit}, \end{aligned}$$
(1)

where m, i, and t are indices of the municipality, restaurant type (dine-in/other types), and time on a monthly basis, respectively. Dependent variable \(y_{mit}\) represents the number of type i restaurants newly approved or closing in municipality m at time t. Variable \(T_{mi}\) is a treatment status dummy that takes one for a dine-in restaurant in prefectures with financial support for reducing business hours, and \(After_{t}\) is a dummy taking one for December 2020 or later. The cross-term of \(T_{mi}\) and \(After_{t}\) is the DID term. Vector \(x_{mit}\) is a set of control variables that includes the one-period lagged term of the prefectural number of positive cases of COVID-19 and its squared term, the cross-term between the one-period lagged term and the restaurant type dummy, the cross-term between the squared one-period lagged number of positive cases and the restaurant type dummy, the cross-term of the treatment status dummy and month dummy variables (e.g., January and February dummies), and the cross-term of quarter (the first, second, third, and fourth quarter dummies) and prefecture fixed effects. The cross-term of the one-period lagged term of the prefectural number of positive cases of COVID-19 and the restaurant type dummy is used to capture the heterogeneous shock by restaurant type discussed above.Footnote 33 Parameters \(\eta _{t}\) and \(\phi _{mi}\) are monthly and municipality-restaurant-type fixed effects, respectively, and \(u_{mit}\) is the error term. The municipality-level restaurant-type fixed effects are controlled by fixed effects estimation with panel data. In Eq. (1), parameter \(\beta _{3}\) corresponds to the DID estimate and is the parameter of interest in capturing the effects of the expansion of financial support if the assumption holds.

An assumption for the internal validity of the DID is the common trend assumption; that is, a counterfactual change in the number of newly approved or closing restaurants in the treatment and control groups must have been the same after December 2020 under no expansion of financial support. A typical mean of testing for the validity of this assumption is to check the trends in target outcomes for the treatment and control groups before the policy intervention. If the changes in the number of newly approved restaurants were the same for both groups before the expansion of financial support for dine-in restaurants, the assumption could be maintained. We employ an event study approach to identify the trends in the target outcomes for the treatment and control groups before the expansion of financial support using the following estimation equation:

$$\begin{aligned} y_{mit} = \alpha _{0}&+ \sum _{k=Apr2019}^{Oct2020}[ \delta _{k}T_{mi} \times 1\{t=k\} ] \nonumber \\&+ \sum _{k=Dec2020}^{Mar2021}[ \delta _{k}T_{mi} \times 1\{t=k\} ] \nonumber \\&+ x'_{mit}\gamma _{2} + \tilde{\eta }_{t} + \tilde{\phi }_{mi} + \epsilon _{mit}, \end{aligned}$$
(2)

where variable \(1\{t=k\}\) is a dummy taking one if an observation is from the kth month. As we set November 2020 as the reference month, parameter \(\delta _{k}\) corresponds to the difference in the number of newly approved or closing restaurants between the treatment and control groups in the kth time period compared to the reference time period. If the estimates of \(\delta _{k}\) before December 2020 are statistically indifferent from zero, we can argue that the common trend assumption holds. We utilize the same control variables as in Eq. (1), except for the cross-term of the treatment status dummy and month dummy variables. Parameters \(\tilde{\eta }_{t}\) and \(\tilde{\phi }_{mi}\) are monthly and municipality-restaurant-type fixed effects, respectively, and \(\epsilon _{mit}\) is the error term. We also estimate the equations for restaurant closings.

5 Results

5.1 Effects on entry

The estimation result of the event study supports the common trend assumption. Figure 7 shows the estimated coefficient of the cross-term of the treatment dummy and the monthly dummy variables and its 95% confidence intervals for Eq. (2). The diamond symbols indicate the estimated coefficients of the cross-term of the treatment dummy and monthly dummy variables, and the bars are the 95% confidence intervals for the estimates.

According to Fig. 7, for almost all months, the estimates of \(\delta _{k}\) are statistically indifferent from zero at the 5% level before the expansion of financial support, suggesting the credibility of common trend assumption in our setting. In other words, policies other than the expansion of financial support after December 2020 for dine-in restaurants, such as the financial support for restaurants reducing their business hours between April and May and the Go to Eat campaign, do not seem to promote new entries into the restaurant industry. Besides, the estimated coefficients for December 2020 or later are positive and statistically significant at the 5% level, and the differences in the number of newly approved restaurants between the treatment and control groups are 5.2–15.5 restaurants more than that in the reference month.

Note that, as the treatment and control groups of the event study are used for the analysis of the effects of the expansion after December 2020, both groups may include non-representative municipalities. For instance, for the financial support for dine-in restaurants between April and May, the municipalities in the treatment group other than those belonging to Tokyo, Kanagawa Prefecture, and Osaka Prefecture did not provide financial support, which may induce attenuation bias for the estimates for April and May 2020. Additionally, the Go to Eat campaign was held in Shizuoka, Hamamatsu, and Okayama, which are used as the control group in Fig. 7 and may induce attenuation biases for the estimates for November 2020. For these concerns, we re-estimate the event study by excluding the inappropriate municipalities in each case and obtain robust results (Figs. 12 and 13).

We added prefecture monthly fixed effects to the estimation models to control for the unobserved prefecture monthly characteristics such as other industry support policies implemented by prefectures and the COVID-19 cases in neighboring prefectures, which could affect both the expansion of financial support and restaurant entries and exits; we found that adding prefecture monthly fixed effects does not affect the estimation results.Footnote 34

Table 5 Effects of the expansion of financial support on restaurant openings

Table 5 summarizes the estimation results of the effect of the expansion of financial support on restaurant openings using the DID approach. The columns show the estimated coefficient on the DID term (“Treated\(\times \)After”), number of observations, average dependent variable for the treated group before the expansion of financial support (“Pre-expansion mean among treated”), magnitude of the DID estimates evaluated by the percentage change from the pre-expansion average for the treated group, and number of municipalities used for estimation. For the entire sample, the coefficient on the DID term is estimated at 4.566, which is statistically significant at the 1% level. The magnitude of the estimate can be interpreted so that, compared to the average value for the treatment group before the expansion, the number of newly approved restaurants increased by 31.4% among the treatment group after the expansion of financial support. This result suggests that the expansion of financial support for restaurants reducing their business hours prompted more restaurant openings.

The magnitude of the estimated effect is robust when we exclude small municipalities, such as towns (machi/cho) and villages (mura/son), from the analysis (column 2). Among small municipalities, the number of newly approved restaurants is low, with many zero values both before and after the expansion of support, which means a lower variation in the dependent variable resulting in noise. The coefficient on the DID term is 6.08, which is statistically significant at the 1% level. The magnitude can be interpreted in that the expansion of the financial support increased the number of newly approved restaurants by 30.0% among the treatment group compared to the average value before the expansion, which is as high as the magnitude for the entire sample.

We conduct a robustness check against the definition of the control group. One could still doubt that an entrepreneur who plans to open a new takeout restaurant may switch to opening a dine-in one by providing seating to obtain financial support; however, this change is likely difficult as explained in Footnote 29. In this case, the number of newly approved takeout restaurants decreases after the expansion of financial support and the estimated effect of the expansion for dine-in restaurants could be overestimated. The estimation results are robust when we change the control groups to other types of restaurants in areas with expansion (column 3) and to both types of restaurants in areas without expansion, such as Shizuoka, Hamamatsu, and Okayama (column 4). In addition, we implemented a difference-in-differences-in-differences (DDD) estimation using the two dimensions of treatment status: the type of restaurant (dine-in or other types of restaurants) and the region (the areas with and without the declaration of state of emergency). We found that the DDD estimate is positive and statistically significant, similar to the DID estimation, and its magnitude is comparable to that of the DID estimate (Table 13).

To further explore the impacts of the expanded financial support on the number of new entrants, we analyze the heterogeneous effects between dine-in restaurants operating mainly during nighttime and other dine-in restaurants. To qualify for financial support, dine-in restaurants were required to close by 8 p.m. Considering that most nighttime-oriented dine-in restaurants typically opened at 5 p.m. during non-pandemic times (Fig. 21), they had only a few hours to operate their businesses and receive financial assistance. Consequently, some of these restaurants might have opted to not open altogether instead of reducing their business hours. As such, if a dine-in restaurant specializing in nighttime operations entered the market after the expansion of financial support, they could have been seeking profit through the financial support rather than providing goods and services to customers. To explore this possibility, we separately counted dine-in restaurants based on their type (nighttime-oriented and others) and re-estimated the impacts of the expanded financial support on entries for both categories,Footnote 35

Table 6 Heterogeneous effects between dine-in restaurants that operate mainly during nighttime and other dine-in restaurants (entry)

Table 6 summarizes the estimation results of the impact of the expansion of financial support by type of dine-in restaurants (nighttime-oriented and others). The units of observation are the municipality, restaurant type (nighttime-oriented dine-in restaurants, other dine-in restaurants, and other types of restaurants), and the time period. We report the coefficients of the DID term (\(Treated \times After\)), the cross-term of the nighttime-oriented dine-in restaurant dummy and after dummy (\(Nighttime \times After\)), and the cross-term of the DID term and the nighttime dummy (\(Nighttime \times Treated \times After\)).Footnote 36 The average number of newly approved dine-in restaurants among the treatment group in the pre-expansion period was 2.596 for nighttime-oriented dine-in restaurants and 7.850 for other dine-in restaurants. According to Table 6, the DID estimate is positive, statistically significant (1.784), and consistent with that in Table 5. The coefficient on the cross-term of the DID term and nighttime dummy is positive but statistically insignificant, suggesting that the expansion of financial support increased the new entrants by 1.784 for both nighttime-oriented and other dine-in restaurants. Compared to the pre-expansion average number of entrants, we can interpret that the support expansion increased the nighttime-oriented dine-in restaurants by 68.7% (=1.784/2.596) and other dine-in restaurants by 22.7% (=1.784/7.850), suggesting a higher impact for nighttime-oriented dine-in restaurants.

Moreover, we conduct a subsample analysis using municipality characteristics to examine the heterogeneity of the impacts based on variables related to the benefits and costs of new restaurant openings. We use two variables for the subsample analysis: population density as of October 2020 and average total rent for vacant restaurants in 2020. The former is a proxy for expected sales because the larger the population is, the higher the demand for food services. The latter is used as a proxy for the opening costs and operating costs of new restaurants. We expect that the effect is larger in areas with high population density and/or with relatively low rent.

Table 7 Heterogeneous effects by municipality characteristics

Table 7 summarizes the results of the heterogeneous effects analysis. We restrict the sample to municipalities with the expansion of the financial support and divide it by the median of each variable. Appendix A.2 explains the data on population density and total rent. Columns 1 and 2 show the results for the municipalities with below and above median population density, respectively. The results for sub-samples by total rent are shown in columns 3 and 4. The data on total rent are available for 54 municipalities. For the subsample analysis, the number of municipalities is below 50, which may lead to problems due to the few clusters used to calculate the cluster-robust standard errors, as discussed by Cameron & Miller (2015). We apply wild cluster bootstrapping with 10,000 replications to tackle the “few clusters” problem using user-written Stata command “boottest” constructed by Roodman et al. (2019). The wild bootstrap cluster p-values and 95% confidence intervals are reported in parentheses and square brackets, respectively.

According to columns 1 and 2 of Table 7, the difference in population density does not significantly affect the magnitude of the effect. The DID estimates are positive, with p-values of 0.065 and 0.000 for areas whose population density is below and above the median, respectively. The estimates imply that, compared to the average value for the treatment group before the support expansion, the numbers of newly approved restaurants increased by 23.9% and 29.5% for below and above the median, respectively. The estimate for the values above the median is around 1.2 times larger than that below the median, implying they do not differ significantly.

However, the effect is larger in areas where the total rent for vacant restaurants is relatively lower. The DID estimates are positive, with p-values below 0.05. This implies that, compared to the average value for the treatment group before the expansion, the numbers of newly approved restaurants increased by 39.5% and 22.2% for below and above the median, respectively (columns 3 and 4). The estimated effect for the areas whose total rent for vacant restaurants is below the median is around 1.8 times larger than that for those above the median.Footnote 37

Notes: The diamond symbols indicate the estimated coefficients on the cross-term of the treatment dummy and the monthly dummy variables, and the bars are the wild bootstrap clusters of 95% confidence intervals robust against municipality-level clustering calculated using user-written Stata command “boottest”(Roodman et al., 2019). We set November 2020 and October 2020 as the reference months for a and b, respectively

5.2 Effects on exit

We conducted the same estimation for restaurant closings using the number of other types of restaurants in the treated areas as the control group. For this analysis, we use two reference months, November 2020 and October 2020. The former is in the same as in Fig. 7, and the latter is used to account for the potential effects of the Go To Eat campaign. As discussed, Fig. 6b shows that the number of restaurant closings in November 2020 was lower compared to the same month of 2019. From the result of the descriptive analysis, we cannot deny the possibility that the Go To Eat campaign prevented restaurant closings.Footnote 38 The campaign aimed to encourage people to eat at dine-in restaurants, while the restaurants could get the subsidy for operating businesses. As such, the campaign might have prevented the restaurants that wanted to continue business from closing but not restaurant openings for the subsidy. Therefore, we used the reference month of October 2020 for the analysis of restaurant closings.

When we use the reference month of November 2020, approximately 80% of the estimates of \(\delta _{k}\) for the pre-expansion period are statistically indifferent from zero at the 5% level, while we obtain four statistically significantly positive estimates for the period (Fig. 8a). The four positive estimates may indicate that the Go To Eat campaign held in November 2020 prevented restaurants from closing. Subsequently, the result suggests a large reduction in restaurant closings among the treated group in January and February 2021, but the estimates are marginally insignificant at the 10% level (p-values were 0.117 and 0.114 for January and February, respectively).

When we change the reference month from November to October 2020, the tendency of the results does not change significantly. All estimates of \(\delta _{k}\) for the pre-expansion period are statistically indifferent from zero at the 5% level (Fig. 8b). For November 2020, the estimate of \(\delta _{k}\) is negative but not statistically significant for the above expectation. The negative estimate might indicate the possibility that the Go To Eat campaign prevented restaurant closings; however, our event study model suggests that, at least on average, the treated and control groups were statistically the same in November 2020 compared to October 2020. Then, the result suggests a statistically significant reduction in restaurant closings among the treated group in January and February 2021 at the 5% and 10% levels, respectively.Footnote 39 The magnitudes are \(-\)15.9 and \(-\)23.2 for January and February, respectively. In this setting, we obtained a large reduction in restaurant closings among the treated in December 2020, but the estimate is not statistically significant (p-value = 0.120). If we use October 2020 as the reference month, we obtain statistically significant estimates for the post-expansion period, while the tendency of the estimates is the same as when November 2020 was the reference month. From the following DID analysis, we utilized the same after dummy as in the analysis on restaurant openings.

Table 8 Effects of the expansion of financial support on restaurant closings

Table 8 summarizes the results of the DID analysis on restaurant closings. We applied wild cluster bootstrapping in the same manner as in Table 7 because the number of clusters is 39. The wild bootstrap cluster p-values and 95% confidence intervals are reported in parentheses and square brackets, respectively.

According to column 1, the coefficient on the DID term is \(-\)5.028, with a p-value of 0.079. The magnitude of the estimate can be interpreted in that, compared to the average value for the treatment group before the expansion, the number of restaurants that went out of business decreased by 30.0% after the support expansion. The results suggest that the expansion of financial support for restaurants reducing their business hours prevented restaurants from going out of business.

5.3 Heterogeneous effects on entrants and exiters

This section examines how the expansion of financial support affects entrants and exiters differently based on their characteristics. We conducted a restaurant-level DID estimation using dummies indicating whether an entrant was a chain restaurant,Footnote 40 whether a new dine-in restaurant applied for both dine-in and takeout services,Footnote 41Footnote 42 whether a new dine-in restaurant had already possessed licenses for takeout services,Footnote 43 whether an exiter is a chain restaurant, the logged duration of operation for an exiter, and a dummy variable indicating the duration of operation for an exiter was below 1 year as dependent variables.

Table 9 Effects on the characteristics of entrants and exiters

Table 9 summarizes the results of the restaurant-level analysis.Footnote 44 We applied wild cluster bootstrapping in the same manner as in Table 7 for columns 4–6 because the number of clusters is 35–38. The wild bootstrap cluster p-values and 95% confidence intervals are reported in parentheses and square brackets, respectively.

We obtained statistically significant DID estimates for the dummy indicating that entrants applied for both dine-in and takeout services and the dummy indicating if the duration of operation for an exiter was below 1 year (columns 2 and 6). The DID estimate for the double-application dummy is negative (\(-\)0.005) and statistically significant at the 5% level. This can be interpreted as the expansion of the financial supports leading to a 25% decrease in double-application among entrants compared to the pre-expansion mean among the treatment group. As discussed in Footnote 29, one could argue that, with the introduction of financial support, people who had initially planned to open takeout or delivery restaurants might have switched to dine-in restaurants to obtain financial support. In this case, they may apply for both dine-in and takeout services, but the DID estimate indicating the decrease in double applications does not support this possibility. This could be because applying for dine-in services requires more facilities and additional investment, which could reduce the benefit from the financial support.

The DID term for the dummy indicating if the duration of operation for an exiter was below 1 year is negative and statistically significant, with a p-value of 0.058. The results imply that the financial support expansion decreased the number of restaurants that exited in the short run compared to the mean of the treatment group before the expansion by 82% among exiters. Previous studies show that firms that are unproductive and less innovative tend to exit the market quickly (e.g., Aga & Francis, 2017; Jovanovic, 1982; Kato et al., 2022; Melitz, 2003; Muzi et al., 2023). This suggests that the restaurants that exited within 1 year could be relatively less productive. The DID estimate suggests that the expansion of financial support could enable low-productivity restaurants to remain in the market. For other dependent variables, we did not observe any statistically significant impacts of the expansion of financial support.

6 Discussion

6.1 Who enters the market after the expansion of financial support?

The estimation results suggest that the expansion of financial support for dine-in restaurants induced an increase in the number of new entrants. The support amount could be substantial after the expansion, given that it exceeded the sales of most dine-in restaurants during the pre-pandemic period when its daily value was JPY 60,000.Footnote 45 However, due to the sharp decline in eating-out expenses caused by the pandemic (Fig. 2) and the government-imposed restrictions, restaurants faced a challenging business environment. The expansion of financial support increased the expected revenue for dine-in restaurants, which could give various people an incentive to open new dine-in restaurants.

There are three possible types of new restaurant entries: (1) “truly” new dine-in restaurants, (2) incumbent restaurants with licenses for takeout and delivery services that obtained an additional license to operate as dine-in restaurants, and (3) people who had initially planned to open takeout or delivery restaurants obtained licenses for both dine-in and takeout services.

The first possibility means a restaurant newly opened as a dine-in service in response to the expanded financial support. In this case, we should also consider the cost of operating dine-in restaurants. The high operating costs may cancel out the increase in expected revenue and the incentive to open such restaurants. The rent for restaurants, one component of the fixed cost, differed,Footnote 46 but the amount of financial support was the same across municipalities in each prefecture between December 2020 and March 2021.Footnote 47 The extent of the incentive induced by the expanded financial support could vary across areas: lower operating costs could lead to higher incentives for opening new dine-in restaurants. The estimation results showing the larger magnitude of the increase in the number of new dine-in restaurants among the areas with lower rent (columns 3 versus 4 in Table 7) support this possibility.

The results also indicate a greater increase in the number of new dine-in restaurants that appear to have been launched with relatively lower opening costs. If entrepreneurs open a dine-in restaurant with the intention of suspending operations immediately, opening costs can be reduced. The proportion of dine-in restaurants with opening costs below the financial support for one month is 12.2% when restaurants open but take an immediate break and 4.4% when restaurants open as usual (panel A of Table 18).Footnote 48 The proportion of dine-in restaurants with opening costs below the financial support amount for two months and three months are 29.2 and 43.9%, respectively.Footnote 49 Actually, the estimation results show that the impact of the expanded financial support on entry is larger among nighttime-oriented dine-in restaurants (Table 6), which could have been considered a break instead of a business hour reduction. Furthermore, if a vacant restaurant is equipped with the necessary facilities for another restaurant service, opening costs can also be reduced. If restaurants inherit land, stores, and equipment from other firms and open but take an immediate break, the proportion of dine-in restaurants with opening costs below the financial support amount for one month is 32.0% (panel A of column 4 in Table 18). For two months, the proportion increases to 48.0%, and for three months, it further rises to 64.0% (panels B and C in column 4 of Table 18). Immediately after the expansion of the financial support was announced, the proportion of dine-in restaurants that began operations in locations where other restaurants had been previously approved increased more than twice compared to the same period in the previous year in areas with low total rent for vacant restaurants (Fig. 15). This implies that some entrepreneurs utilized vacant restaurants with the necessary facilities to reduce the cost of opening a new dine-in restaurant in time to apply for financial support.Footnote 50

The second possibility for the new dine-in restaurants is that incumbent restaurants with licenses for takeout and/or delivery services obtained additional licenses for dine-in operations to become eligible for financial support. If this was the case, the number of new dine-in restaurants that had already licenses for takeout services could have increased after the expansion of financial support. However, our results do not support the increase in the number of those new dine-in restaurants (column 3 of Table 9). Additionally, individuals who had initially planned to open takeout or delivery restaurants may have applied for both dine-in and takeout services (the third possibility). However, the estimation results do not support this possibility (column 2 of Table 9). As discussed in Footnote 29, obtaining licenses for dine-in services requires more facilities and additional investment compared to obtaining licenses for takeout and/or delivery restaurants. This could potentially reduce the benefits gained from the financial support, leading to the scenario where incumbents may not have acquired additional licenses for dine-in restaurant operations.

The COVID-19 pandemic has had a significant impact on the demand for eating out. According to Fig. 2, the demand for dining out decreased substantially after March 2020, and it took 3 years for it to return to pre-pandemic levels. However, despite this trend, our data show a notable increase in the number of new dine-in restaurants during the early stages of the pandemic. Additionally, these new restaurants had relatively low opening and operation costs. For instance, when a vacant restaurant was used for opening a new restaurant, it might indicate a lack of potential customers or other problems in the area, making it difficult to generate market revenue. Furthermore, our data show an increase in the number of newly approved dine-in restaurants that closed within 30 days of approval during the first quarter of 2021 (after the expansion of support) compared to FY2019 (Fig. 16), especially in February and March 2021, despite the decrease in the proportion of exits from young restaurants discussed in Section 5.3.Footnote 51 These findings suggest that the new businesses were established mainly to obtain financial aid rather than a long-term vision of providing better goods and services for customers. This confirms the results of previous studies that show reducing entry barriers leads to less profitable and marginal new firms (e.g., Branstetter et al., 2014; De Meza, 2002; Santarelli & Vivarelli, 2002). Although the policy of supporting new restaurant entrants in COVID-19 was a coincidence, it is unlikely to be effective. Considering the importance of supporting new firm entries for maintaining economic growth and securing employment during a recession (Audretsch, 2007; Aghion et al., 2009), alternative policies need to be considered.

6.2 Financial support and market exits

The estimation results show that the increase in financial support led to a decrease in the number of dine-in restaurants closing down. Specifically, among those restaurants that did close, the percentage of those that did so within a year decreased significantly (82%). As previously discussed, because previous studies show that less productive and innovative firms are more likely to exit the market quickly (e.g., Aga & Francis, 2017; Jovanovic, 1982; Kato et al., 2022; Melitz, 2003; Muzi et al., 2023), the restaurants that exited the market within 1 year could have been relatively unproductive. The results suggest that the financial support might have enabled low-productivity restaurants to remain in the market. This result is consistent with previous studies that found government support programs, such as public guarantees on private loans and subsidies during the COVID-19 shock, to support less productive firms that would otherwise have exited the market, thus enabling them to survive (e.g., Belghitar et al., 2022; Block et al., 2022; Dörr et al., 2022; Honda et al., 2023; Hoshi et al., 2023; Morikawa, 2021; Muzi et al., 2023). This weakens the cleansing effects of recessions (recessions typically remove low-productivity firms from the market and encourage high-productivity firms to enter the market) (e.g., Dörr et al., 2022; Muzi et al., 2023).

6.3 Potential impacts on the restaurant industry and policy implications

The results not only suggest the possibility that the expansion of financial support weakened the cleansing effects of the recession, as discussed in previous studies, but also the possibility that the expansion increased the number of entrants focused on obtaining financial support rather than providing better goods and services for customers. As such, the financial support for restaurants during the COVID-19 recession should have included systems to prevent new entrants, especially undesirable entrants.

One possible measure to prevent new entrants is to provide financial support only to incumbent restaurants when business hour reductions are required. For instance, Germany’s Corona Bridging Aid for SMEsFootnote 52 and other Japanese programs to assist businesses affected by the pandemicFootnote 53 supported only those established before the pandemic. The local governments required dine-in restaurants to reduce their nighttime business hours by offering financial support and imposing monetary penalties following the support expansion. To prevent undesirable new entrants, a system that provides financial support and imposes monetary penalties on incumbent restaurants (started a business before the pandemic) could be used, while only imposing penalties on new entrants (started a business during the pandemic before nighttime restrictions were enforced by local governments). One could argue that imposing penalties only on new entrants might inhibit entries onto the restaurant market. However, since the program aimed at restricting nighttime business, nighttime-oriented dine-in restaurants might have been restricted, but daytime-oriented dine-in restaurants and takeout/delivery restaurants were unlikely to be restricted. The restriction on new nighttime-oriented dine-in restaurants could align with the government’s goal of reducing infection clusters in dine-in restaurants during nighttime.Footnote 54

Another possible measure is to set varying amounts of financial support based on the sales of individual restaurants, even when providing financial support to new entrants. Since the financial support aims to compensate for the reduced sales due to the nighttime business hour reduction, the amount of financial support based on sales is more reasonable than a uniform amount. Local governments revised the amount of financial support for dine-in restaurants that had to reduce their nighttime business hours from a uniform amount to an amount based on individual sales after April 2021. For instance, between April 12, 2021, and March 11, 2022, the Tokyo Metropolitan government set the amount of financial support based on the daily sales in previous years (2019 or 2020) for each incumbent restaurant and based on the daily sales between the opening date and April 11, 2021, for restaurants that had operated within two months.Footnote 55 Since the total rent (a component of fixed costs of operating restaurants) differs across the municipalities in a prefecture (panels B and C of Table 10), the uniform amount can increase the incentives for restaurants to enter the market in a certain area. The estimation results support this possibility. The amount of financial support based on the sales of individual restaurants could reduce the fluctuation of the incentive to enter the market due to financial support and prevent undesirable entrants.

7 Conclusions

This study investigates the impact of financial support for the compensation of business hour restrictions during the pandemic on dine-in restaurant entries. Our findings reveal that the expansion of financial support from December 2020 to March 2021 increased the number of dine-in restaurant openings and decreased the number of dine-in restaurant closures. Throughout FY 2020, the number of restaurant openings remained consistent with the pre-pandemic trend on an annual basis, and the number of restaurant closures was even lower than predicted by pre-pandemic data, despite the decreased demand for eating out. This suggests that there were excessive entries in the restaurant industry. The results also indicate that the expansion had a greater impact in areas with lower opening and operating costs, while it did not vary based on the measure anticipating potential sales. In the first quarter, from December 2020 to March 2021, our data present an increase in the number of newly approved dine-in restaurants that closed within 30 days of approval compared to FY2019. This is consistent with previous studies that found universal government support programs lead to an increase in less profitable and marginal firm entries.

During the pandemic, financial support was provided to compensate for the restrictions on dine-in restaurant business hours. However, unlike other support programs, this support was offered to both possible entrants and incumbents. As a result, the expanded financial support not only prevented firm exits but also increased entries. Unfortunately, due to the lack of a system to prevent new, particularly undesirable, entrants, the entrants induced by the financial support cannot be considered desirable for the restaurant market. To address this issue, the financial support should have been expanded with measures to prevent new entries, especially those deemed undesirable. One potential solution could involve restricting applications to only incumbent dine-in restaurants and varying the amount of financial support based on the sales of individual restaurants. This approach was implemented for other programs, and it was applied to the financial support for dine-in restaurants after mid-April 2021.

This study has some limitations. One limitation is the generalizability of our results. As discussed in Section 3, we collected data mainly from the municipalities in the Tokyo metropolitan Area, but large cities in other prefectures also declared a second state of emergency. As such, our results could be used for policymaking in urban areas, but it is challenging to apply them to the entire Japan, including rural areas. An expansion of this study to a more generalized population could be the scope of future studies. It is also important to acknowledge the limitations concerning the external validity of our findings for other contexts, different industries, and different countries and regions. The policy impacts of financial support for new firms are contingent upon the unique context that entrepreneurs face within each country and region or within an industry. Therefore, generalizing our results to other contexts should be done with caution. Future research could focus on validating the external validity of our findings by examining the effects of similar policies implemented during recessions in different countries.

Another limitation is that because of data limitations, we did not analyze the long-term impact of financial support on entries. The data are available up to April or May 2021 and do not cover the period after financial support was completely discontinued. Our results suggest that some dine-in restaurants that opened during the expansion of financial support may have ceased their operations due to reduced support amount after April 2021. In other words, there could have been a further decline in the number of these restaurants after support was completely terminated. Under this scenario, the entrants during the period of financial support expansion may have little contribution to the efficiency of the restaurant market. The evaluation of the long-term impacts on the restaurant industry should be a focus of future studies. The productivity of new entrants in response to the expansion of financial support should be examined. The expansion of financial support may induce the entry of low-productive restaurants. Even if such restaurants continue their operations after the discontinuation of financial support, it would not contribute to the efficiency of the restaurant market. This aspect is not addressed in this paper owing to data limitations and could be a subject for future studies.
