Many scholars argue that liberalization increases both economic growth and income inequality in developed economies. However, there is limited research on how liberal economic policies shape the earnings of different income groups in the national economy. The current study thus attempts to fill this gap in the literature by examining a panel dataset of 15 advanced industrial societies during the years 1970-2010. According to the results, long-run measures of liberalization increase the incomes of the top 0.1%, but does not return significant results for the incomes of the top 1.0% and top 10%. Furthermore, no discernible effect of liberalization is observed for the incomes of the bottom 90%. When taken together, although most researchers focus on inter-group inequality by examining how liberalization augments the incomes of top earners vis-à-vis bottom earners, the evidence of this study indicates scholars should also focus on intra-group inequality among top earners, as liberalization seems to benefit only a very small segment of elite earners in the national economy.
许多学者认为，自由化会在发达经济体中同时提高经济增长和收入不平等。然而，关于自由经济政策如何塑造国民经济中不同收入群体的收入，相关研究还很有限。因此，本研究试图通过考察 1970 年至 2010 年期间 15 个先进工业社会的面板数据集来填补这一文献空白。根据研究结果，长期的自由化措施提高了前 0.1%人群的收入，但对前 1.0%和前 10%人群的收入没有显著影响。此外，自由化对底层 90%人群的收入没有明显影响。总之，尽管大多数研究人员通过考察自由化如何提高高收入者相对于低收入者的收入来关注群体间不平等，但本研究的证据表明，学者们也应该关注高收入者内部的不平等，因为自由化似乎只使国民经济中非常小的一部分精英收入者受益。
