The empirical studies on this issue are not encouraging, since they favor constant returns in search. However, this research is troubled by all sorts of selection bias. We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their specific skills well. They face a tradeoff between match quality and the cost of extended search. This tradeoff differs between regions, because search in larger regions is more efficient. Then, interregional mobility and trade lead to a pattern of specialization where large regions undertake more search intensive activities. Empirical evidence for the United States corroborates the implications of the model. Search can explain about 75% of the wage differentials between large metropoles and small cities.
