Thesis advisor: Philip E. Strahan / In the first essay of this dissertation, I study the information synergies between deposit-taking and lending activities of large banks. I use the influx of Chinese international students into US universities to identify a local deposit shock. I find that banks that are more exposed to this shock increase their local credit supply in small business loans, but not mortgages. The results support the notion that deposit can be informative: it conveys signals about local economic activities. Such information affects banks expectation about future local demand and thus banks’ lending decisions. The second essay investigates the relationship between banks geographic concentration and liquidity risk management. I find that geographic concentrations measured on different sides of banks’ balance sheet have opposite effects on banks’ liquidity risk management behaviors during the 2007-2009 liquidity crisis. The overall results are consistent with the view in the literature that geographic concentrated banks invest more in soft information production. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.
