We quantify the impact of unexpectedly assigned tasks on overtime work in the context of Japanese government officials. Data on overtime work are typically less reliable. We overcome this problem by using mobile phone location data, which enables us to precisely measure the nighttime population...

This paper revisits the case for flexible vs. fixed exchange rate regime in a two-country model with firm heterogeneity and nominal wage rigidity under incomplete financial markets. Dampening nominal exchange rate fluctuations simultaneously stabilizes the firm turnover in the export market....

This paper explores the role played by product variety and quality in a real business cycle model.Firms are heterogeneous in terms of their specific quality as well as productivity level. Firms which have costly technology enter in the period of high aggregated demand and produce high quality...
