Asset Prices and Unemployment Fluctuations (with Patrick J. Kehoe, Virgiliu Midrigan, and Elena Pastorino) [Link] [NBER Link], Review of Economic Studies, 2022.
Discount-rate variation can generate the observed fluctuations in unemployment in a standard matching model if workers accumulate human capital on the job as in the data. No need for sticky wages or other frictions in contracting. No need for a small fundamental surplus. Search models can therefore deliver on their original promise: to account for unemployment fluctuations with a story of involuntary unemployment and contracts in the agents' best interests.
On the Importance of Household Versus Firm Credit Frictions in the Great Recession (with Patrick J. Kehoe, Virgiliu Midrigan, and Elena Pastorino) [Link] [Data and Code], Review of Economic Dynamics, 2020.
A model supporting the view that the employment decline during the Great Recession would have been less severe if instead of focusing on easing firms’ access to credit, the government had devoted an equal amount of resources to alleviating households’ credit constraints.
A New Keynesian Q Theory and the Link between Inflation and the Stock Market [Link] [SSRN Link] [Online Appendix] [Data and Code], Review of Economic Dynamics, 2018.
The Q theory of investment changes if prices are sticky, and it links asset prices, investment and inflation better than you probably thought.

A Neoclassical Model of the World Financial Cycle (with Yan Bai, Patrick J. Kehoe, and Fabrizio Perri) [Link] [Slides] [Online Appendix]
Are asset prices in Emerging Markets driven by developments in Advanced Economies? A long-run risk model with defaultable, long-term corporate and sovereign debt to account separately for bond and stock price movements in the U.S. and emerging markets.
A New Keynesian Model of the Term Structures of Equity and Bond Returns (or Macro-Finance Separation by Force of Habit) (with Francisco Vazquez-Grande) [Link] [Online Appendix]
What are the macroeconomic drivers of asset prices? A downward-sloping term structure of equity and upward-sloping term structures of interest rates (i.e., hard-to-explain evidence) arise endogenously in a general-equilibrium model with nominal rigidities, productivity shocks and nonlinear habits in consumption. The model even captures the cyclicality of the term structures. We also show how to unite nonlinear habits and a production economy without compromising the ability of the model to fit macroeconomic variables.
Welfare Implications of Asset Pricing Facts: Should Central Banks Fill Gaps or Remove Volatility? [Link] [SSRN Link] [Online Appendix]
Measures from asset markets about the welfare cost of fluctuations are the few pieces of evidence about welfare we have. Macroeconomists who study the benefits of stabilization policies should also use that evidence to test their models. I build a New Keynesian model with habit formation that explains the evidence about welfare costs of fluctuations, but that is observationally equivalent in its quantity implications to a textbook New Keynesian model. Observational equivalence requires habit externalities, which generate a policy tradeoff. The standard optimal stabilization policy turns on its head.
Accounting for Risk in a Linearized Solution (or Risk-Adjusted Linearizations of Dynamic Equilibrium Models) (with David Lopez-Salido and Francisco Vazquez-Grande) [Link] [Code (Matlab)] [Code (Julia), implemented by William Chen] [Online Appendix]
A linear approximation technique to solve for the equilibrium allocation and to price assets in closed form when we care about risk (e.g., Campbell-Cochrane habits, risk-sensitive preferences, stochastic volatility, disaster risk, ...). If you want to study time-varying risk premia and the effect of risk on the economy this approximation (aka a first-order perturbation around the risky steady state) is in many ways better than a third-order perturbation around the deterministic steady state.
Macro-Finance Separation by Force of Habit (with David Lopez-Salido and Francisco Vazquez-Grande) [Link] [SSRN Link]
How to unite nonlinear habits and a production economy without compromising the ability of the model to fit macroeconomic variables.
The Term Structure of the Welfare Cost of Uncertainty [Link]
The marginal welfare cost of economic uncertainty has a term structure that is a simple transformation of the term structures of the equity premium and interest rates. I extract 20 years of evidence from index option markets to infer a downward-sloping, volatile and countercyclical term structure of welfare costs.
Reassessing the Role of Stock Prices in the Conduct of Monetary Policy [Link]
On the fragility of some numerical procedures to solve for optimal Taylor-type rules.

Monetary Policy and Heterogeneous Agent Search (with Patrick J. Kehoe, Elena Pastorino, and Sergio Salgado)
Documents how the effects of monetary policy differ across people, especially in terms of labor market outcomes, builds a model to rationalize them, and illustrates the differential effects of different monetary policy rules.
