Abstract: For nearly two decades banks in the United States have consolidated in record numbers—in terms of both frequency and the size of the merging institutions. Rhoades (1996) hypothesizes that the main motivations were increased potential for geographic expansion created by changes in state laws regulating branching and a more favorable antitrust climate. To look for evidence of economic incentives to exploit these improved opportunities for consolidation, we examine how consolidation affects expected profit, the riskiness of profit, profit efficiency, market value, market-value efficiencies, and the risk of insolvency. Our estimates of expected profit, profit risk, and profit efficiency are based on a structural model of leveraged portfolio production that was estimated for a sample of highest-level U.S. bank holding companies in Hughes, Lang, Mester, and Moon (1996). Here, we also estimate two additional measures that gauge efficiency in terms of the market values of assets and of equity. Our findings suggest that the economic benefits of consolidation are strongest for those banks engaged in interstate expansion and, in particular, interstate expansion that diversifies banks' macroeconomic risk. Not only do these banks experience clear gains in their financial performance, but society also benefits from the enhanced bank safety that follows from this type of consolidation.
