REGIONAL VARIATIONS IN LABOR DEMAND ELASTICITY: EVIDENCE FROM U.S. COUNTIES
利用1988-2010年美国县级面板数据，估计了四个行业的劳动力需求工资弹性，发现弹性存在显著空间差异，且与产业专业化、竞争、自然禀赋和城市化相关，亲商州的弹性更高。
ABSTRACT We use a large panel dataset covering the period 1988–2010 to estimate county specific own‐wage elasticity of labor demand in the U.S. for four highly aggregated industries: construction, finance/insurance/real‐estate/service, manufacturing, and retail trade. Our estimation of a random parameter panel data model yields significant evidence of spatial variations in wage elasticity of labor demand. We relate the spatial variation in elasticity to differences in county characteristics like industry specialization, industry competition, levels of natural amenity and urbanization. Using a regression discontinuity approach we also find that probusiness states have higher labor demand elasticity.
