Firm Productivity Differences From Factor Markets
研究了企业如何适应本地要素市场，发现中国行业内劳动力成本差异导致全要素生产率差异达3-12%，劳动力市场均质化可提高实际收入1.33%。
Abstract We model firm adaptation to local factor markets in which firms care about both the price and availability of inputs. The model is estimated by combining firm and population census data, and quantifies the role of factor markets in input use, productivity and welfare. Considering China's diverse factor markets, we find that within an industry interquartile labor costs vary by 30–80%, leading to 3–12% interquartile differences in TFP. In general equilibrium, homogenization of labor markets would increase real income by 1.33%. Favorably endowed regions attract more economic activity, providing new insights into within‐country comparative advantage and specialization.
