|December 2014||Does the Geographic Expansion of Bank Assets Reduce Risk?|
with Luc Laeven, Ross Levine: w20758
We develop a new identification strategy to evaluate the impact of the geographic expansion of bank holding company (BHC) assets across U.S. metropolitan statistical areas (MSAs) on BHC risk. We find that the geographic expansion of bank assets reduces risk. Moreover, geographic expansion reduces risk more when BHCs expand into economically dissimilar MSAs, i.e., MSAs with different industrial structures and business cycles. We do not find that geographic diversification improves loan quality. Our results are consistent with arguments that geographic expansion lowers risk by reducing exposure to idiosyncratic local risks and inconsistent with arguments that geographic expansion, on net, increases risk by reducing the ability of BHCs to monitor loans and manage risks.
|December 2011||The Valuation Effects of Geographic Diversification: Evidence from U.S. Banks|
with Luc Laeven, Ross Levine: w17660
This paper assesses the impact of the geographic diversification of bank holding company (BHC) assets across the United States on their market valuations. Using two novel identification strategies based on the dynamic process of interstate bank deregulation, we find that exogenous increases in geographic diversity reduce BHC valuations. These findings are consistent with the view that geographic diversity makes it more difficult for shareholders and creditors to monitor firm executives, allowing corporate insiders to extract larger private benefits from firms.
