【摘要】We document how within-city inequality vary across cities. While the residual wage gaps between the top and the median earners increase with the city size, the gaps between the median and the bottom earners shrink. We develop a spatial equilibrium model where heterogeneous individuals sort into entrepreneurs or workers in different industries and cities. Entrepreneurs benefit more than workers in larger cities due to knowledge spillovers, leading to higher top inequality. Bottom inequality shrinks in larger cities because low-income workers must be compensated to overcome the higher living costs. Empirical tests using U.S. data broadly support our theoretical predictions.
