We investigate how the better integration of U.S. banks across states has affected economic volatility within states. In theory, the link between bank integration and volatility is ambiguous; integration tends to dampen the impact of bank capital shocks on state activity, but it amplifies the impact of firm collateral shocks. Empirically, the net effect has been stabilizing as year-to-year fluctuations in employment growth within states fall as that state's banks become better integrated (via holding companies) with banks in other states. The magnitudes are large, and the effects are most pronounced in states with relatively undiversified economies. Consistent with our model, we find the link between economic growth and bank capital within a state weakens with integration, whereas the link...

Theory suggests that bank integration (financial integration generally) can magnify or dampen the business cycles, depending on the importance of shocks to firm collateral versus shocks to the banking sector. In this paper, we show empirically that bank integration across U.S. states over the late 1970s and 1980 dampened economic volatility within states. Internationally, however, we find that foreign bank integration, which advanced widely during the 1990s, has been either unrelated to volatility of firm investment spending or positively related to that volatility. The results suggest the possibility that business spending may become more volatile as countries open their banking sectors to foreign entry.
