This article provides new evidence on how access to finance affects technological innovation and establishes the role of labor practices in shaping this relation. We exploit a unique setting, pre-Civil War America, where staggered adoption of free banking laws across states encouraged bank entry, and variation in the use of exploited workers in agriculture generated differences in producers’ demands for labor-saving technologies. Results show that access to finance spurred innovation; the positive effect on agricultural innovation diminished with labor exploitation. We establish the causal role of labor exploitation using the 1850s cholera pandemic and the influx of Irish immigrants.

The National Banking Acts (NBAs) of 1863–1864 established rules governing the amounts and locations of interbank deposits, thereby reshaping the bank networks. Using unique data on bank balance sheets and detailed interbank deposits in 1862 and 1867 in Pennsylvania, we study how the NBAs changed the network structure and quantify the effect on financial stability in an interbank network model. We find that the NBAs induced a concentration of interbank deposits at both the city and bank levels, creating systemically important banks. Although the concentration facilitated diversification, contagion would have become more likely when financial center banks faced large shocks.
