Constrained Efficiency with Adverse Selection and Directed Search
Constrained efficient allocation (CE) is characterized in a model of adverse selection and directed search (Guerrieri, Shimer, and Wright (2010)). CE is defined to be the allocation that maximizes welfare, the ex-ante utility of all agents, subject to the frictions of the environment. -
Asset Encumbrance, Bank Funding and Financial Fragility
How does asset encumbrance affect the fragility of intermediaries subject to rollover risk? We offer a model in which a bank issues covered bonds backed by a pool of assets that is bankruptcy remote and replenished following losses. -
A Microfounded Design of Interconnectedness-Based Macroprudential Policy
To address the challenges posed by global systemically important banks (G-SIBs), the Basel Committee on Banking Supervision recommended an “additional loss absorbency requirement” for these institutions. Along these lines, I develop a microfounded design of capital surcharges that target the interconnectedness component of systemic risk. -
Risk Sharing in the Presence of a Public Good
This paper studies an economy where agents can spend resources on consuming a private good and on funding a public good. There is asymmetric information regarding agents’ relative preference for private versus public good consumption. -
Managerial Compensation Duration and Stock Price Manipulation
I build a model of optimal managerial compensation where managers each have a privately observed propensity to manipulate short-term stock prices. -
A Wake-Up-Call Theory of Contagion
We propose a novel theory of financial contagion. We study global coordination games of regime change in two regions with an initially uncertain correlation of regional fundamentals. -
The Threat of Counterfeiting in Competitive Search Equilibrium
Recent studies in monetary theory show that if buyers can use lotteries to signal the quality of bank notes, counterfeiting does not occur in a pooling equilibrium. In this paper, I investigate the robustness of this non-existence result by considering an alternative trading mechanism. -
Money and Price Posting under Private Information
We study price posting with undirected search in a search-theoretic monetary model with divisible money and divisible goods. Ex ante homogeneous buyers experience match specific preference shocks in bilateral trades. The shocks follow a continuous distribution and the realization of the shocks is private information. -
Counterfeit Quality and Verification in a Monetary Exchange
Recent studies on counterfeiting in a monetary search framework show that counterfeiting does not occur in a monetary equilibrium. These findings are inconsistent with the observation that counterfeiting of bank notes has been a serious problem in some countries. -
Composition of International Capital Flows: A Survey
We survey several key mechanisms that explain the composition of international capital flows: foreign direct investment, foreign portfolio investment and debt flows (bank loans and bonds). In particular, we focus on the following market frictions: asymmetric information in capital markets and exposure to liquidity shocks.
