Scholars differ on whether Federal Reserve intervention mitigated banking panics during the Great Depression and in recent years. The last panic prior to the Depression sheds light on this debate. In April 1929, a fruit fly infestation in Florida forced the U.S. government to quarantine fruit shipments from the state and destroy infested groves. When Congress recessed in June without approving compensation for farmers, depositors in citrus growing regions began withdrawing deposits from banks, culminating in runs on institutions in the financial center of Tampa and surrounding cities. Using archival evidence, we describe how the Federal Reserve Bank of Atlanta halted the spread of the panic by rushing currency to member banks. Analysis based on a new micro-level database of commercial bank...

Because California was a pioneer in the development of intrastate branching, we use its experience during the 1920s and 1930s to assess the effects of the expansion of large-scale, branch-banking networks on competition and the stability of banking systems. Using a new database of individual bank balance sheets, income statements, and branch establishment, we examine the characteristics that made a bank a more likely target of a takeover by a large branching network, how incumbent unit banks responded to the entry of branch banks, and how branching networks affected the probability of survival of banks during the Great Depression. We find no evidence that branching networks expanded by acquiring "lemons"; rather those displaying characteristics of more profitable institutions were more lik...

It is often argued that branching stabilizes banking systems by facilitating diversification of bank portfolios; however, previous empirical research on the Great Depression offers mixed support for this view. Analyses using state-level data find that states allowing branch banking had lower failure rates, while those examining individual banks find that branch banks were more likely to fail. We argue that an alternative hypothesis can reconcile these seemingly disparate findings. Using data on national banks from the 1920s and 1930s, we show that branch banking increases competition and forces weak banks to exit the banking system. This consolidation strengthens the system as a whole without necessarily strengthening the branch banks themselves. Our empirical results suggest that the effe...
