职业错配与市场势力

Occupational mismatch and market power
Journal of Development Economics · 2025 · Felipe Balmaceda

中文摘要

本文表明,本地劳动力市场势力为发展中经济体相对于发达经济体自雇比例更高提供了理论解释。劳动力市场势力造成职业错配——相对于竞争基准,过多工人选择自雇。由于劳动力市场势力,工人对提高受雇就业生产率的技能投资不足,而对提高自雇生产率的技能投资过度。在一定条件下,这会加剧职业错配。我们还考虑了一个数量型产品市场竞争模型,其中自雇者构成竞争性边缘。产品市场竞争提高了对工人的竞争强度,并减少了职业错配。

Abstract

This paper shows that local labor market power provides a rationale for the higher prevalence of self-employment in developing economies relative to developed economies. Labor market power creates occupational mismatch–too many workers choose self-employment relative to the competitive benchmark. Because of labor market power, workers underinvest in skills that increase paid employment productivity and overinvest in those that enhance self-employment productivity. Under certain conditions, this exacerbates the occupational mismatch. We also consider a quantity-type product market competition model where self-employed individuals form a competitive fringe. Product-market competition increases the intensity of competition for workers and reduces occupational mismatch.
