The Macroeconomic Implications of Rising Wage Inequality in the United States
构建了一个不完全市场生命周期模型，研究美国工资结构变化（大学溢价上升、性别差距缩小、工资波动加剧）对教育选择、家庭时间分配和储蓄的影响，发现近期出生队列平均福利上升。
In recent decades, American workers have faced a rising college premium, a narrowing gender gap, and increasing wage volatility. This paper explores the quantitative and welfare implications of these changes. The framework is an incomplete-markets life cycle model in which individuals choose education, intrafamily time allocation, and savings. Given the observed history of the U.S. wage structure, the model replicates key trends in cross-sectional inequality in hours worked, earnings, and consumption. Recent cohorts enjoy welfare gains, on average, as higher relative wages for college graduates and for women translate into higher educational attainment and a more even division of labor within the household.
