Occupational Matching and Cities
研究发现大城市工人有更多职业选择，能形成更好的职业匹配并获得更高工资；模型校准表明更好的职业匹配质量解释了约35%的大城市工资溢价和三分之一的不平等加剧。
In this paper, I document that workers in larger cities have significantly more occupational options than workers in smaller ones. They are able to form better occupational matches and earn higher wages. I also note differences in occupation reallocation patterns across cities. I develop a dynamic model of occupation choice that microfounds agglomeration economies and captures the empirical patterns. The calibration of the model suggests that better occupational match quality accounts for approximately 35 percent of the observed wage premium and one-third of the greater inequality in larger cities.
