The primary challenge to assessing the legal origins view of comparative financial development is identifying exogenous changes in legal systems. We assemble new data on Shanghai's British and French concessions between 1845 and 1936. Two regime changes altered British and French legal jurisdiction over their respective concessions. By examining the changing application of different legal traditions to adjacent neighborhoods within the same city and controlling for military, economic, and political characteristics, we offer new evidence consistent with the legal origins view: the financial development advantage in the British concession widened after Western legal jurisdiction intensified and narrowed after it abated.

Angel investor tax credits are used globally to spur high‐growth entrepreneurship. Exploiting their staggered implementation in 31 U.S. states, we find that they increase angel investment yet have no significant impact on entrepreneurial activity. Two mechanisms explain these results: crowding out of alternative financing and low sensitivity of professional investors to tax credits. With a large‐scale survey and a stylized model, we show that low responsiveness among professional angels may reflect the fat‐tailed return distributions that characterize high‐growth startups. The results contrast with evidence that direct subsidies to firms have positive effects, raising concerns about promoting entrepreneurship with investor subsidies.
