August 2020Cheap Thrills: the Price of Leisure and the Global Decline in Work Hours
with Nikolai Roussanov, Mathieu Taschereau-Dumouchel: w27744
The real price of recreation goods and services has fallen dramatically over the last century. At the same time, hours per worker have also been on a steady decline. As recreation goods make leisure time more enjoyable, we investigate if the fall in their price has contributed to the decline in work hours. Using aggregate data from OECD countries, as well as disaggregated data from the United States, we provide evidence that the two are strongly related. To identify the effect of recreation prices on hours worked, we use variation in the bundle of recreational goods across demographic groups to instrument for the changing price of leisure faced by these groups over time. We then construct a macroeconomic model with general preferences that allows for trending relative prices and work hours...
June 2020Bank Heterogeneity and Financial Stability
with Itay Goldstein, Lin Shen, Haotian Xiang: w27376
We study how heterogeneity in banks’ asset holdings affects fragility. In the model, banks face a risk of bank runs and have to liquidate long-term assets in a common market to repay runners. Liquidation prices are depressed when many banks sell their assets at the same time. When banks are homogeneous, their selling behaviors are synchronized, and bank runs are exacerbated. We show that differentiating banks to some extent enhances the stability of all banks, even those whose asset performance ends up being weaker. Our analyses provide new insights about the regulation of banking sector’s architecture and the design of government support during crises.
March 2018Short-Run Pain, Long-Run Gain? Recessions and Technological Transformation
with Nikolai Roussanov, Mathieu Taschereau-Dumouchel: w24373
Recent empirical evidence suggests that job polarization associated with skill-biased technological change accelerated during the Great Recession. We use a standard neoclassical growth framework to analyze how business cycle fluctuations interact with the long-run transition towards a skill-intensive technology. In the model, since adopting the new technology disrupts production, firms prefer to do so in recessions, when profits are low. Similarly, workers also tend to learn new skills during downturns. As a result, recessions are deeper during periods of technological transition, but they also speed up adoption of the new technology. We document evidence for these mechanisms in the data. Our calibrated model is able to match both the long-run downward trend in routine employment and the d...
