Wages, Hiring Standards, and Firm Size
构建了一个企业选择工资和招聘标准以最大化利润的模型，分析了生产率与保留工资的相关性如何影响企业规模、工资和招聘标准之间的关系，并解释了工资与企业规模之间U形或单调递增关系的实证现象。
We present a model of firm behavior in which firms choose a wage and a hiring standard to maximize their profits. The correlation between productivity and reservation wage affects the relationship among firm size, wages, and hiring standards. In the special case where labor productivity is a linear function of a worker's reservation wage, we find that in the absence of hiring costs wages are monotonically increasing with firm size. Any positive hiring costs, however, result in an interval of sufficiently small firms within which wages decrease with firm size. In all cases, among sufficiently large firms, wages increase with firm size. A review of previous empirical evidence finds that in some occupations the relationship between wages and firm size is U-shaped, while in other occupations wages increase monotonically with firm size. These empirical findings are consistent with our theoretical results.
