Local Labor Markets and the Evolution of Inequality
研究了美国过去30年工资不平等加剧的现象，指出全国层面的分析忽略了地方劳动力市场的差异，提出了一个理论框架并重新评估了不平等变化。
US labor markets have experienced rising inequality over the past 30 years—as evidenced by an increased gap in wages earned by high-skill workers (e.g., college graduates) and low-skill workers (e.g., high school graduates). Empirical evidence documenting this evolution of inequality comes from studies that assess wage-education gradients at the national level. But of course people work in local labor markets that differ in important ways. We provide a theoretical framework for evaluating inequality changes when individuals work in local labor markets, and we give an empirical reassessment of inequality changes in light of the insights that emerge from our framework.
