Wages and Commuting: Quasi-natural Experiments' Evidence from Firms that Relocate
利用企业搬迁引起的通勤距离变化，研究工资如何补偿通勤成本，发现短期内工资补偿很小，但三年后通勤每增加1公里工资上涨约0.15%。
We examine individual-level compensating differentials for commuting distance in a quasi-natural experiment setting by examining how wages respond to changes in commuting distance induced by firm relocations. This set-up enables us to test for the relevance of job search frictions within labour market models. Due to the quasi-experimental set-up, we are able to avoid a range of endogeneity issues. We demonstrate that a 1 km increase in commuting distance induces an almost negligible wage increase in the year after the relocation but a more substantial wage increase of about 0.15% three years later. © 2013 Royal Economic Society.
