A Dynamic Theory of Collateral Quality and Long-Term Interventions
We study a dynamic model of collateralized lending under adverse selection in which the quality of collateral assets is endogenously determined by hidden effort. Complementarities in incentives lead to non-ergodic dynamics: Asset quality and output grow when asset quality is high, but stagnate or deteriorate otherwise. Inefficiencies remain, even in the most efficient competitive equilibrium?investment and output are vulnerable to spells of lending market illiquidity, and these spells may persist because of suboptimal effort. Nevertheless, benevolent regulators without commitment can destroy ...
The use of collateral in bilateral repurchase and securities lending agreements
We use unique data from U.S. bank holding company-affiliated securities dealers to study the use of collateral in bilateral repurchase and securities lending agreements. Market participants? use of collateral differs substantially across asset classes: for U.S. Treasury securities transactions, we find that haircuts are large enough to provide full protection from default, whereas the same is not usually true for equities transactions. Further, although most of the equities in our sample are each associated with a unique haircut, most of the U.S. Treasury securities are each associated with ...
Adverse Selection, Risk Sharing and Business Cycles
I consider a real business cycle model in which agents have private information about an idiosyncratic shock to their value of leisure. I consider the mechanism design problem for this economy and describe a computational method to solve it. This is an important contribution of the paper since the method could be used to solve a wide class of models with heterogeneous agents and aggregate uncertainty. Calibrating the model to U.S. data I find a striking result: That the information frictions that plague the economy have no effects on business cycle fluctuations.
Securities Financing and Asset Markets: New Evidence
This paper presents new evidence on bilateral securities financing based on the Federal Reserve's Senior Credit Officer Opinion Survey, which was launched in the wake of the financial crisis to provide a window into this otherwise opaque market. The survey asks large broker-dealers about terms at which they fund client positions, and the demand for such funding, across several different collateral types. Within asset classes, reported changes in spreads, haircuts, and other financing terms move closely together, and we show that they also covary with the state of the underlying cash ...
Finance and Inequality : The Distributional Impacts of Bank Credit Rationing
We analyze reductions in bank credit using a natural experiment where unprecedented flooding differentially affected banks that were more exposed to flooded regions in Pakistan. Using a unique dataset that covers the universe of consumer loans in Pakistan and this exogenous shock to bank funding, we find two key results. First, banks disproportionately reduce credit to new and less-educated borrowers, following an increase in their funding costs. Second, the credit reduction is not compensated by relatively more lending by less-affected banks. The empirical evidence suggests that adverse ...
Corporate Governance and Risk Management at Unprotected Banks: National Banks in the 1890s
Managers' incentives may conflict with those of shareholders or creditors, particularly at leveraged, opaque banks. Bankers may abuse their control rights to give themselves excessive salaries, favored access to credit, or to take excessive risks that benefit themselves at the expense of depositors. Banks must design contracting and governance structures that sufficiently resolve agency problems so that they can attract funding from outside shareholders and depositors. We examine banks from the 1890s, a period when there were no distortions from deposit insurance or government interventions ...
Old, Frail, and Uninsured: Accounting for Puzzles in the U.S. Long-Term Care Insurance Market
Half of U.S. 50-year-olds will experience a nursing home stay before they die, and one in ten will incur out-of-pocket long-term care expenses in excess of $200,000. Surprisingly, only about 10% of individuals over age 62 have private long-term care insurance (LTCI). This paper proposes a quantitative equilibrium optimal contracting model of the LTCI market that features screening along the extensive margin. Frail and/or poor risk groups are ordered a single contract of no insurance that we refer to as a rejection. According to our model, rejections are the main reason that LTCI take-up rates ...

Adverse Selection, Lemons Shocks and Business Cycles
Asymmetric information is crucial for understanding the disruption of the supply of credit. This paper studies a dynamic economy featuring asymmetric information and resulting adverse selection in credit markets. Entrepreneurs seek loans from banks for projects, but asymmetric information about entrepreneurs' riskiness causes a lemons problem: relatively safe entrepreneurs do not get funded. An increase in the riskiness of some entrepreneurs raises interest rate spreads, aggravates adverse selection, and shrinks the supply of bank credit. The model calibrated to the U.S. economy generates ...
Stress Tests and Information Disclosure
We study an optimal disclosure policy of a regulator that has information about banks (e.g., from conducting stress tests). In our model, disclosure can destroy risk-sharing opportunities for banks (the Hirshleifer effect). Yet, in some cases, some level of disclosure is necessary for risk sharing to occur. We provide conditions under which optimal disclosure takes a simple form (e.g., full disclosure, no disclosure, or a cutoff rule). We also show that, in some cases, optimal disclosure takes a more complicated form (e.g., multiple cutoffs or nonmonotone rules), which we characterize. We ...
