We study the impact of an epidemic disease on modern financial development by exploiting geographic variations in the precolonial survival conditions of the TseTse fly, which transmits an epidemic disease that is harmful to humans and fatal to livestock in Africa. Using newly georeferenced data, we discover that firms and households in regions historically more exposed to the epidemic disease have less access to external financing today. Exploring the channels, we find that people in historically infested regions are less likely to trust others and financial institutions, to share credit information and to learn and adopt new financial technologies.

Abstract This article studies how minimum-wage policies affect capital investment using the industrial census of manufacturing firms in China, where minimum-wage policies vary across counties. Exploiting discontinuities in minimum-wage policy at county borders, we find that minimum wages increase capital investment. The investment response to minimum wages is stronger for firms that are labor intensive, that have more room for technological improvement, and that cannot sufficiently pass on labor costs to consumers. A natural experiment based on county jurisdictional changes further assures the causal relationship.
