Intermediary balance sheets
We document the cyclical properties of the balance sheets of different types of intermediaries. While the leverage of the bank sector is highly procyclical, the leverage of the nonbank financial sector is acyclical. We propose a theory of a two-agent financial intermediary sector within a dynamic model of the macroeconomy. Banks are financed by issuing risky debt to households and face risk-based capital constraints, which leads to procyclical leverage. Households can also participate in financial markets by investing in a nonbank ?fund? sector where fund managers face skin-in-the-game ...

Monetary Policy with Racial Inequality
I develop a heterogeneous-agent New-Keynesian model featuring racial inequality in income and wealth, and studies interactions between racial inequality and monetary policy. Black and Hispanic workers gain more from accommodative monetary policy than White workers mainly due to higher labor market risks. Their gains are larger also because of a larger proportion of them are hand-to-mouth, while wealthy White workers gain more from asset price appreciation. Monetary and fiscal policies are substitutes in providing insurance against cyclical labor market risks. Racial minorities gain even more ...

Computing Equilibria of Stochastic Heterogeneous Agent Models Using Decision Rule Histories
This paper introduces a general method for computing equilibria with heterogeneous agents and aggregate shocks that is particularly suitable for economies with private information. Instead of the cross-sectional distribution of agents across individual states, the method uses as a state variable a vector of spline coefficients describing a long history of past individual decision rules. Applying the computational method to a Mirrlees RBC economy with known analytical solution recovers the solution perfectly well. This test provides considerable confidence on the accuracy of the method.

Frictional Intermediation in Over-the-Counter Markets
We extend Duffie, G?arleanu, and Pedersen?s (2005) search theoretic model of over-the-counter (OTC) asset markets, allowing for a decentralized inter-dealer market with arbitrary heterogeneity in dealers? valuations or inventory costs. We develop a solution technique that makes the model fully tractable and allows us to derive, in closed form, theoretical formulas for key statistics analyzed in empirical studies of the intermediation process in OTC markets. A calibration to the market for municipal securities reveals that the model can generate trading patterns and prices that are ...

Offshoring, low-skilled immigration, and labor market polarization
During the last three decades, jobs in the middle of the skill distribution disappeared, and employment expanded for high- and low-skill occupations. Real wages did not follow the same pattern. Although earnings for the high-skill occupations increased robustly, wages for both low- and middle-skill workers remained subdued. We attribute this outcome to the rise in offshoring and low-skilled immigration, and we develop a three-country stochastic growth model to rationalize this outcome. In the model, the increase in offshoring negatively affects the middle-skill occupations but benefits the ...

Bad Jobs and Low Inflation
We study a model in which firms compete to retain and attract workers searching on the job. A drop in the rate of on-the-job search makes such wage competition less likely, reducing expected labor costs and lowering inflation. This model explains why inflation has remained subdued over the last decade, which is a conundrum for general equilibrium models and Phillips curves. Key to this success is the observed slowdown in the recovery of the employment-to-employment transition rate in the last five years, which is interpreted by the model as a decline in the share of employed workers searching ...

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.

Bad Jobs and Low Inflation
The low rate of inflation observed in the U.S. over the entire past decade is hard to reconcile with traditional measures of labor market slack. We show that an alternative notion of slack that encompasses workers' propensity to search on the job explains this missing inflation. We derive this novel concept of slack from a model in which a drop in the on-the-job search rate lowers the intensity of interfirm wage competition to retain or hire workers. The on-the-job search rate can be measured directly from aggregate labor-market flows and is countercyclical. Its recent drop is corroborated by ...

The Nonlinear Effects of Fiscal Policy
We argue that the fiscal multiplier of government purchases is increasing in the size of the spending shock: more expansionary government spending shocks generate larger multipliers and more contractionary shocks generate smaller multipliers. We empirically document this pattern across time, countries, and modes of financing. We propose a neoclassical mechanism that hinges on the relationship between fiscal shocks, their form of financing, and the response of labor supply across the wealth distribution. An incomplete markets model predicts that the aggregate labor supply elasticity is ...
