This paper shows that labor market search frictions do not explain fluctuations in the labor wedge per se. However, the introduction of extensive and intensive margin clarifies that measuring the MRS in terms of total hours artificially introduces procyclicality in the MRS. When the MRS is...

This paper proposes an empirical method for estimating a long-run trend for the unemployment rate that is grounded in the modern theory of unemployment. I write down an unobserved components model and identify the cyclical and trend components of the underlying unemployment flows, which in turn...

Estimates of labor market slack can diverge a great deal depending on how slack is defined. We calculate slack using five different concepts that all focus on a single labor market indicator, the unemployment rate. We show that the estimates all provide useful—but different—information. We...

The Federal Open Market Committee (FOMC) has tied its asset purchases to a “substantial improvement” in labor market conditions. While we don’t speculate on what the FOMC means by substantial improvement, we do explore the level of monthly job gains that would gradually deliver the...

Okun’s law is a statistical relationship between unemployment and GDP that is widely used as a rule of thumb for assessing the unemployment rate—why it might be at a certain level or where it might be headed, for example. Unfortunately, the Okun’s law relationship is not stable over time,...

This paper evaluates the ability of autoregressive models, professional forecasters, and models that incorporate unemployment flows to forecast the unemployment rate. We pay particular attention to flows-based approaches–the more reduced-form approach of Barnichon and Nekarda (2012) and the...

This paper assesses whether labor market frictions, in the form of searching and matching, can help explain movements in the labor wedge—the gap between the marginal rate of substitution (MRS) and the marginal productivity of labor in a perfectly competitive business cycle model. Results...
