We develop a method to use the one-time cross-sectional impact of a cleanly identified shock to identify its aggregate impact through the use of a factor model. We apply this methodology to evaluate the importance of fluctuations to the commitment to a currency peg for macroeconomic outcomes during the gold standard period in the United States. The presidential election in 1896 provides a cleanly identified positive shock to commitment to the gold standard. After the election, bank leverage increased substantially, particularly in states where gold was in greater use. Using the latent factor identified by the election, we find that full commitment to gold had the potential to reduce the volatility of real activity overall by a significant amount in the last two decades of the nineteenth century, as well as substantially mitigate the economic depression starting in 1893.

Do banks matter for growth, and if so, how? This paper examines the effects of national banks in the United States from 1870 to 1900. I use the discontinuity in entry caused by a large minimum size requirement to identify the effects of banking. For the counties on the margin between getting a bank and not, gaining a bank increased production per person by 10%. National banks in rural areas improved agriculture over manufacturing, moving counties toward geographic comparative advantage. Since these banks made few long-term loans, the evidence suggests that the provision of working capital and liquidity matters for growth.
