December 2016Relationship Lending and the Great Depression: Measurement and New Implications
with Jon Cohen, Gary Richardson: w22891
The Great Depression remains ground zero for studying the non-monetary effects of financial crises. Despite the abundant scholarship on the period, lack of disaggregated data on lending activities has constrained our ability to measure the impact on the real economy of a collapse in long-term lending relationships. We propose here a novel way to extract cross-sectional differences in relationship lending from geographically aggregated financial statements. We find that the banking crises of the early 1930s, by destroying these relationships and the soft yet crucial information garnered from them, explain one-eighth of the economic contraction observed during the Depression. This effect comes specifically from small bank failures which alone explain one-third of the Depression. Large bank f...
January 2016Liquidity Regulation and Credit Booms: Theory and Evidence from China
with Zheng Michael Song: w21880
Many countries try to mitigate business cycle fluctuations by regulating the activities of their banks. We develop a theoretical framework to study the endogenous response of the banking sector and the implications for the aggregate economy. Under fairly mild conditions, we find that stricter liquidity standards can generate unintended credit booms as attempts to arbitrage the regulation change the allocation of savings across banks and the allocation of lending across markets. We then apply our framework to study recent events in China. We show that a regulatory push to increase bank liquidity and cap loan-to-deposit ratios in the late 2000s accounts for one-third of China ’s unprecedented credit boom and one-half of the increase in interbank interest rates over the same period. We also f...
August 2014Resource Allocation and Inefficiency in the Financial Sector
I analyze whether banks are efficient at allocating resources across intermediation activities. Competition between lenders means that resources are needed to draw borrowers into credit matches. At the same time, imperfect information between lenders and borrowers means that resources are also needed for screening. I show that the privately optimal allocation of resources is constrained inefficient. In particular, too many resources are spent on getting rather than vetting borrowers but, once properly vetted, not enough matches are retained. Uninformed lending is thus inefficiently high, informed lending is inefficiently low, and a tax on matching activities helps remedy the situation.
May 2014Inflation Announcements and Social Dynamics
with Jing Cynthia Wu: w20161
We propose a new framework for understanding the effectiveness of central bank announcements when firms have heterogeneous inflation expectations. Expectations are updated through social dynamics and, with heterogeneity, not all firms choose to operate, putting downward pressure on realized inflation. Our model rationalizes why countries stuck at the zero lower bound have had a hard time increasing inflation without being aggressive. The same model also predicts that announcing an abrupt target to disinflate will cause inflation to undershoot the target whereas announcing gradual targets will not. We present new empirical evidence that corroborates this prediction.
