We document three changes in postwar US macroeconomic dynamics: (i) the procyclicality of labor productivity has vanished, (ii) the relative volatility of employment has risen, and (iii) the relative (and absolute) volatility of the real wage has risen. We propose an explanation for all three...

Over the past two decades, technological progress has been biased towards making skilled labor more productive. What does skill-biased technological change imply for business cycles? To answer this question, we construct a quarterly series for the skill premium from the CPS and use it to...

We investigate unemployment due to mismatch in the US over the past three decades. We propose an accounting framework that allows us to estimate the overall amount of mismatch unemployment as well as the contribution of the frictions that caused the mismatch. Mismatch is quantitatively important...

Firms select not only how many, but also which workers to hire. Yet, in standard search models of the labor market, all workers have the same probability of being hired. We argue that selective hiring crucially affects welfare analysis. Our model is isomorphic to a search model under random...

Standard macroeconomic models underpredict the volatility of unemployment fluctuations. A common solution is to assume wages are rigid. We explore whether this explanation is consistent with the data. We show that the wage of newly hired workers, unlike the aggregate wage, is volatile and...

Was the increase in income inequality in the US due to permanent shocks or merely to anincrease in the variance of transitory shocks? The implications for consumption and welfaredepend crucially on the answer to this question. We use CEX repeated cross-section data onconsumption and income to...
