How Do Hours Worked Vary with Income? Cross-Country Evidence and Implications
构建了新的跨国工作时间数据库，发现低收入国家成人平均工作时间显著高于高收入国家，且该模式在不同性别、年龄和教育水平人群中均成立；跨国生产率与福利差异比现有估计更大。
This paper builds a new internationally comparable database of hours worked to measure how hours vary with income across and within countries. We document that average hours worked per adult are substantially higher in low-income countries than in high-income countries. The pattern of decreasing hours with aggregate income holds for both men and women, for adults of all ages and education levels, and along both the extensive and intensive margin. Within countries, hours worked per worker are also decreasing in the individual wage for most countries, though in the richest countries, hours worked are flat or increasing in the wage. One implication of our findings is that aggregate productivity and welfare differences across countries are larger than currently thought.
