This paper analyzes the possibility and the consequences of rational bubbles in a dy- namic economy where financially constrained firms demand and supply liquidity. Bub- bles are more likely to emerge, the scarcer the supply of outside liquidity and the more limited the pledgeability of...

The paper elicits a mechanism by which private leverage choices exhibit strategic complementarities through the reaction of monetary policy. When everyone engages in maturity transformation, authorities have little choice but facilitating refinancing. In turn, refusing to adopt a risky balance...

The sub-prime crisis has shown a harsh spotlight on the practices of securities underwriters, which provided too many complex securities that proved to ultimately have little value. This uproar calls attention to the fact that the literature on intermediaries has carefully analyzed their...

We explore the link between liquidity and investment in a an overlapping generation model with a standard asynchronicity between firms' access to and need for cash. Imperfect pledgeability hinders the capacity of capital markets to resolve this asynchronicity, resulting in credit rationing and a...

Traditional banking is built on four pillars: SME lending, access to public liquidity, deposit insurance, and prudential supervision. This vision has been shattered by repeated bailouts of shadow financial institutions. This paper puts ``special depositors and borrowers'' at the core of the...

The recent unravelling of the Eurozone's financial integration raised concerns about feedback loops between sovereign and banking insolvency. This paper provides a theory of the feedback loop that allows for both domestic bailouts of the banking system and sovereign debt forgiveness by...

This paper analyzes the theoretical and quantitative implications of optimal capital taxation in the neoclassical growth model with aggregate shocks and incomplete markets. The model features a representative-agent economy with proportional taxes on labor and capital. I first consider the case...

We provide a price theory for incomplete markets that extends the traditional Walrasian analysis. We derive formulas expressing the consumption response to current and future changes in interest rates and income. Our analysis provides a natural decomposition of these responses into substitution...

Currently both the International Monetary System (IMS) and the International Price Systems (IPS) are dominated by the U.S. The emergence of China, both as reserve currency and as a currency of invoicing, is likely to disrupt this status quo. We provide a framework to understand the forces that...

This paper discusses two simple decompositions for aggregate productivity analysis in the presence of distortions and in general equilibrium. The first is a generalization of Baqaee and Farhi (2017) and the second is due to Petrin and Levinsohn (2012). In the process, we propose a new...
