New Market Power Models and Sex Differences in Pay
利用一家连锁超市不同岗位的工资和离职率数据，估计男女劳动力供给弹性，发现女性弹性更低，从而用买方垄断模型解释零售业女性相对工资较低的现象。
In the context of certain models, it is possible to infer the elasticity of labor supply to the firm from the elasticity of the quit rate with respect to the wage. We use this strategy to estimate the elasticity of labor supply for men and women workers at a chain of grocery stores, identifying separation elasticities from differences in wages and separation rates across different job titles within the firm. We estimate that women have lower elasticities, so a Robinson-style monopsony model can explain reasonably well the lower relative pay of women in the retail grocery industry.
