Is There a Social Kuznets Curve? The Influence of Labour Standards on Inequality
研究了1990-2000年90个国家的核心劳动标准对收入不平等的影响，发现两者呈倒U型曲线关系，且实施效果取决于政治和法律制度质量。
Abstract This study empirically investigates the impact of core labour standards on income inequality for a range of 90 countries from 1990–2000. A synthetic index of labour standards is computed by means of a Multiple Correspondence Analysis and no significant correlation is found with the Gini index. One of the reasons pointed out is that the effective implementation of core labour standards depends on the quality of the country's political and legal systems. Using instrumental variables in a TSLS model, we found an inverse ‘U’ shaped curve between the new endogenous index of core labour standards and income inequality.
