Abstract: | 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. |
