This paper delves into infrastructure projects initiated during the dictatorship in Spain, particularly the construction of reservoirs and dams. These projects were instrumental in bolstering support for right-wing factions advocating for Franco’s regime over the years. However, our research reveals a notable trend: areas where dams were erected by the regime demonstrate diminished political backing for right-wing parties in the post-dictatorship era. We present evidence suggesting that this phenomenon is driven by the use of forced labor in dam construction by the regime, as inferred from the proximity to concentration camps. To address endogeneity concerns, we instrument dam construction with river gradient suitability.

电力储备：佛朗哥治下西班牙大坝建设的政治遗产


本文深入探讨了西班牙独裁统治期间启动的基础设施项目，特别是水库和水坝的建设。这些项目有助于加强多年来对倡导佛朗哥政权的右翼派系的支持。然而，我们的研究揭示了一个值得注意的趋势：该政权修建水坝的地区表明，在后独裁时代，右翼政党的政治支持有所减少。我们提供的证据表明，这种现象是由该政权在大坝建设中使用强迫劳动驱动的，这从靠近集中营可以推断出来。为了解决内生性问题，我们根据河流坡度的适宜性对大坝建设进行检测。
