In this paper we address the time-inconsistency of optimal debt policy—the incentive for a current government to “manipulate interest ratesâ€â€”raised in Lucas and Stokey’s celebrated 1983 paper. The literature that followed suggested various ways to fully overcome...

In an influential paper Angeletos (2002) argues that, even in the absence of state contingent debt, governments can achieve a complete market outcome through issuing bonds of different maturities. The key insight is that fluctuations in the yield curve are exploited through holding or selling...

This paper estimates an identified VAR on US data to gauge the dynamic response of the job finding rate, the worker separation rate, and vacancies to monetary policy shocks. I develop a general equilibrium model that can account for the large and persistent responses of vacancies, the job...

This paper generalizes the standard habit formation model to an environment in which agents form habits over individual varieties of goods as opposed to over a composite consumption good. We refer to this preference specification as ‘deep habit formation’. Under deep habits, the demand...

Studies of disaggregated price data document a robust, positive relationship between nominal exchange rate (NER) volatility and the variability of relative prices for cities separated by national borders. This relationship is interpreted as evidence of sticky prices. This paper shows that a...

Detailed macroeconomic data to accompany the article in the Review of Economic Dynamics

We develop a model of investment with financial constraints and use it to investigate the relation between investment and Tobin’s q. A firm is financed partly by insiders, who control its assets, and partly by outside investors. When insiders’ wealth is scarce, they earn a rate of...

Disturbances affecting agents' intertemporal substitution are the key driving force of macroeconomic fluctuations. We reach this conclusion exploiting the asset pricing implications of an estimated general equilibrium model of the U.S. business cycle with a rich set of real and nominal frictions

This paper explains market turbulence, such as the recent dotcom boom/bust cycle, as equilibrium industry dynamics triggered by technology innovation. When a major technology innovation arrives, a wave of new firms implement the innovation and enter the market. However, if the innovation...
