This technical appendix provides additional details and robustness tests for the main article "Jewish Persecutions and Weather Shocks: 1100–1800." It includes descriptive statistics for five-year, one-year, and grain price data, as well as further analysis on the effects of temperature and rainfall on Jewish persecution. The appendix also discusses the impact of soil quality and state antiquity on persecution probabilities, and presents results from regressions controlling for spatial and serial correlation. The analysis shows that lower soil quality and more recent states are associated with higher persecution probabilities in response to temperature and rainfall shocks. The rainfall data support the main findings, showing that lower rainfall increases persecution probability, especially in areas with poor soil quality. The analysis also includes additional historical evidence, such as the Black Death, Armleder massacres, and Haidamack massacres, which are consistent with the theory that negative weather shocks lead to Jewish persecution. The appendix also discusses the data sources and methods used, including the use of temperature data from Guiot and Corona (2010), rainfall data from Pauling et al. (2006), and urban density data from Bosker et al. (2013). The analysis concludes that the relationship between supply shocks and Jewish persecution weakened as state capacity increased, and that the data support the main findings of the article.This technical appendix provides additional details and robustness tests for the main article "Jewish Persecutions and Weather Shocks: 1100–1800."
