There is an ongoing debate about the effect of changes in labor regulations such as Right-to-Work (RTW) laws on rising income inequality in the U.S. In this paper, we use a relatively new methodology, the Synthetic Control Method A¢Â€Â“ which we argue is more suitable for analyzing this data A¢Â€Â“ to examine the impact of a stateA¢Â€Â™s adoption of an RTW law on income inequality. We use a wide range of inequality measures for states that enacted their RTW laws between the 1960s and the 2000s. Unlike some earlier papers that suggest a negative link between the RTW laws and correlates of inequality such as wages, we find that RTW laws had no significant impact on income inequality in these states.

工作权法是否影响收入不平等？来自美国各州使用合成控制方法的证据

关于劳动法规（例如工作权利 (RTW) 法）的变化对美国收入不平等加剧的影响一直存在争论 在本文中，我们使用了一种相对较新的方法，即综合控制方法 A¢ “我们认为这更适合分析此数据 A¢ 以检查州 A 采纳 RTW 法对收入不平等的影响。我们对在 1960 年代和 2000 年代之间颁布 RTW 法律的州使用了广泛的不平等措施。与一些早期的论文表明 RTW 法律与不平等的相关因素（如工资）之间存在负相关，我们发现 RTW 法律对这些州的收入不平等没有显着影响。
