We provide estimates of profit shifting for over 2 million firm-year observations in 100 countries over the period 2009–2020. Employing nonparametric estimation techniques within a mainstay model of profit shifting, we examine how the profits of both parent and subsidiary firms within a multinational group respond to marginal changes in the composite tax indicator. The key advantage of this approach is that it yields firm-year estimates of profit shifting. Multinational firms engage in extensive profit shifting by maintaining affiliates in low-tax countries and zero-tax havens. Multinational groups with an ultimate tax-haven owner exhibit the largest profit response to tax incentives. Our new database opens important avenues for analyzing the sources and effects of profit shifting.

关于企业内部和不同时间利润转移的全球证据


我们为 2009 年至 2020 年期间 100 个国家/地区的 200 多万次公司年度观察提供了利润转移的估计值。在利润转移的主流模型中采用非参数估计技术，我们研究了跨国集团内母公司和子公司的利润如何响应综合税收指标的边际变化。这种方法的主要优点是它可以产生公司年度利润转移的估计值。跨国公司通过在低税收国家和零税收避风港设立分支机构来进行广泛的利润转移。拥有最终避税天堂所有者的跨国集团对税收优惠的利润反应最大。我们的新数据库为分析利润转移的来源和影响开辟了重要途径。
