Commuting, Migration and Local Employment Elasticities
通过理论和实证发现，本地就业对劳动力需求冲击的弹性因劳动力市场的通勤开放程度而异，并量化了通勤成本降低带来的福利收益约为3.3%。
We provide theory and evidence that the elasticity of local employment to a labor demand shock is heterogeneous depending on the commuting openness of the local labor market. We develop a quantitative general equilibrium model that incorporates spatial linkages in goods markets (trade) and factor markets (commuting and migration). We quantify this model to match the observed gravity equation relationships for trade and commuting. We find that empirically-observed reductions in commuting costs generate welfare gains of around 3.3 percent. We provide separate quasi-experimental evidence in support of the model’s predictions using the location decisions of million dollar plants.
