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...

We analyze the general equilibrium effects of countercyclical unemployment benefit policies. Our heterogenous-agent model features costly job search with imperfect insurance of unemployment risk and individual savings. Our model predicts: (1) the additional unemployment under a countercyclical...

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...

Quantitative risk management relies on a constellation of tools that are used to analyze portfolio risk. We develop the standard toolkit, which includes betas, risk budgets and correlations, in a general, coherent, mnemonic framework centered around marginal risk contributions. We apply these...

We analyze the consequences of ambiguity aversion in the Diamond-Mortensen-Pissarides (DMP) search and matching model. Our model features a cross-section of workers whose productivity is the sum of an aggregate and a match-specific component. Firms are ambiguity averse towards match-specific...

We provide firm-level evidence that Federal Open Market Committee 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 component (CBI) and a conventional monetary component...

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...
