Abstract:We use the unique circumstances that led to the Panic of 1907 to analyze its consequences for non-financial corporations. The panic was triggered by a shock to New York's trust companies that was unrelated to any major non-financial corporations affiliated with those institutions. Using newly collected data, we find that corporations with close ties to the trust companies that faced severe runs experienced an immediate decline in their stock price, and performed worse in the years following the panic: they earned fewer profits and paid fewer dividends, and faced higher interest rates on their debt.
