FRICTIONAL SORTING: THE IMPACTS OF DUAL CONSTRAINTS ON MOBILITY AND HOUSING SUPPLY IN CHINA
利用均衡分类模型和中国微观数据，评估了流动性和住房供给双重约束对工人分类行为的影响，量化了福利和分配后果。反事实模拟显示，降低迁移成本会增加福利并减少不平等，但效果取决于沿海地区的住房供给弹性。
Abstract Using an equilibrium sorting model and microdata from China, we evaluate the impacts of dual constraints on mobility and housing supply on workers’ sorting behavior, quantifying the welfare and distributional consequences. Counterfactual simulations show that lowering migration costs associated with institutional restrictions and migrant‐specific amenities would increase welfare and reduce inequality by moving workers from inland to coastal regions in China. These impacts depend on the housing supply elasticity in coastal regions. Similarly, the impacts of relaxing housing supply restrictions depend on mobility constraints. Results highlight the policy complementarities between reducing the two kinds of frictions.
