|March 2017||The Cross Section of Bank Value|
with Mark Egan, Adi Sunderam: w23291
We study the determinants of value creation within U.S. commercial banks. We focus on three theoretically-motivated drivers of bank value: screening and monitoring, "safe" deposit production, and synergies between deposit-taking and lending. To assess the relative contributions of each, we develop novel measures of banks' deposit productivity and asset productivity and use these measures to evaluate the cross-section of bank value. We find that variation in deposit productivity explains the majority of variation in bank value, consistent with theories emphasizing safe-asset production. We also find evidence of meaningful value creation from synergies between deposit-taking and lending. Overall, our findings suggest that banks are primarily "special" due to their unique liability structure ...
|January 2012||The Safe-Asset Share|
with Gary B. Gorton, Andrew Metrick: w17777
We document that the percentage of all U.S. assets that are "safe" has remained stable at about 33 percent since 1952. This stable ratio is a rare example of calm in a rapidly changing financial world. Over the same time period, the ratio of U.S. assets to GDP has increased by a factor of 2.5, and the main supplier of safe financial debt has shifted from commercial banks to the "shadow banking system." We analyze this pattern of stylized facts and offer some tentative conclusions about the composition of the safe-asset share and its role within the overall economy.
