This paper reviews a framework for studying the aggregation and propagation of microeconomic shocks in general equilibrium. We discuss the determinants of aggregate measures of real economic activity, like real GDP, real domestic absorption, and aggregate productivity in both efficient and...

We quantify the connection between inequality and business cycles in a medium-scale New Keynesian model with tractable household heterogeneity, estimated with aggregate and cross-sectional data. We find that inequality substantially amplifies cyclical fluctuations. The primary source of this...

Using a new dataset on sectoral credit exposures covering financial and non-financial sectors in 115 economies over the period 1940-2014, we document the following evidence that corporate debt plays a key role in explaining boom-bust cycles, financial crises, and slow macroeconomic recoveries:...

China and South Korea both experienced substantial increases in household debt through 2021, and now both countries face a weakening economy. This essay gleans lessons from the "credit-driven household demand channel" (e.g., Mian and Sufi 2018) to explore how the two economies will fare in the...

This paper proposes a non-linear New Keynesian Phillips curve (Inv-L NK Phillips Curve) to explain the surge of inflation in the 2020s. Economic slack is measured as firms' job vacancies over the number of unemployed workers. After showing empirical evidence of statistically significant...

Using a new survey of firms in New Zealand, we document how exogenous variation in the macroeconomic uncertainty perceived by firms affects their economic decisions. We use randomized information treatments that provide different types of information about the first and/or second moments of...

Employment and participation rates for US prime age women rose steadily during the second half of the 20th century. In the last 30 years, however, those rates stagnated, even as employment and participation rates for women in other industrialized countries continued to rise. I discuss the role...

We study how human capital diversification, in the form of double majoring, affects the response of earnings to labor market shocks. Double majors experience substantial protection against earnings shocks, of 56%. This finding holds across different model specifications and data sets....

We show that time variation in risk premia leads to time-varying idiosyncratic income risk for workers. Using US administrative data on worker earnings, we show that increases in risk premia lead to lower earnings for low-wage workers; these declines are primarily driven by job separations. By...

Using an administrative payroll dataset for 2.6 million retail workers, we find that the staggered rollout of a major e-commerce firm's fulfillment centers reduces traditional retail workers' income in geographically proximate counties by 2.4%. Wages of hourly workers, especially part-time...
