We propose a general simulation-based procedure for estimating the quality of approximate policies in heterogeneous-agent equilibrium models, which allows verification that such approximate solutions describe a near-rational equilibrium. Our procedure endows agents with superior knowledge of the...

We propose a simulation-based procedure for evaluating approximation accuracy of numerical solutions of general equilibrium models with heterogeneous agents. We measure the approximation accuracy by the magnitude of the welfare loss suffered by agents from following sub-optimal policies. Our...

We propose a general simulation-based procedure for estimating quality of approximate policies in heterogeneous-agent equilibrium models, which allows to verify that such approximate solutions describe a near-rational equilibrium. Our procedure endows agents with superior knowledge of the future...

We show that time-varying risk premium in financial markets can explain a key yet puzzling feature of labor markets: the large differences in unemployment risk across worker age-groups over the business cycle. Our search model features a time-varying risk premium and learning about unobserved...

We provide firm-level evidence that FOMC announcements have real effects by changing expectations of firm profitability. We use an existing decomposition of a monetary policy shock into a central bank information (CBI) component and a conventional monetary (MP) component. We find: (1) firms with...

We use mean-field game theory to quantitatively compare two unemployment insurance (UI) extension policies commonly used during recessions: raising benefit levels versus extending the duration of benefits. Our heterogenous-agent model features costly job search and individual savings. Our...

We present a theory in which limited risk sharing of idiosyncratic labor income risk plays a key role in determining the dynamics of interest rates. Our production-based model relates the cross-sectional distribution of labor income risk to observable aggregate labor market variables. Our model...

Risk analysis involves gaining deeper insight into the sources of risk, and evaluating whether these risks accurately reflect the views of the portfolio manager. In this paper, we show how to extend standard volatility analytics to shortfall, a measure of extreme risk. Using two examples, we...

Ljungqvist and Sargent (2017) (LS) show that unemployment fluctuations can be understood in terms of a quantity they call the "fundamental surplus". However, their analysis ignores risk premia, a force that Hall (2017) shows is important in understanding unemployment fluctuations. We show how...
