This paper investigates the shape of the relationship between household income inequality and economic growth. More precisely we search for the existence of threshold values in this relationship by employing a dynamic panel smooth transition regression model to account for potential endogeneity problems. We find that there do exist threshold values (that are different for different groups of countries): below the threshold, household income inequality is growth enhancing, while above the threshold, inequality has a negative or no effect on economic growth.

寻找家庭收入不平等与增长关系的阈值

本文研究了家庭收入不平等与经济增长之间关系的形状。更确切地说，我们通过采用动态面板平滑过渡回归模型来考虑潜在的内生性问题，以寻找这种关系中阈值的存在。我们发现确实存在阈值（不同国家组的阈值不同）：在阈值以下，家庭收入不平等促进增长，而在阈值以上，不平等对经济增长没有负面影响或没有影响。
