Banks and Development: Jewish Communities in the Italian Renaissance and Current Economic Performance

Abstract

Are dierences in local banking development long-lasting? Do they aect long-term economic performance? I answer these questions by relying on an historical development that occurred in Italian cities during the 15th century. A sudden change in the Catholic doctrine had driven the Jews toward money lending. Cities that were hosting Jewish communities developed complex banking institutions for two reasons: …rst, the Jews were the only people in Italy who were allowed to lend for a pro…t and, second, the Franciscan reaction to Jewish usury led to the creation of charity lending institutions, the Monti di Pieta, that have survived until today and have become the basis of the Italian banking system. Using Jewish demography in 1500 as an instrument, I provide evidence of (1) an extraordinary persistence in the level of banking development across Italian cities (2) large eects of current local banking development on per-capita income. Additional …rm-level analyses suggest that well-functioning local banks exert large eects on aggregate productivity by reallocating resources toward more e¢ cient …rms. I exploit the expulsion of the Jews from the Spanish territories in Italy in 1541 to argue that my results are not driven by omitted institutional, cultural and geographical characteristics. In particular, I show that, in Central Italy, the dierence in current income between cities that hosted Jewish communities and cities that did not exists only in those regions that were not Spanish territories in the 16th century.
