Tax Progressivity and Its Effect on Economic Growth

This paper investigates whether there is a relationship between progressivity of personal income taxation and output growth. Additionally a relation between progressivity of personal income taxation and volatility of output growth is examined. There is a gap in the existing literature examining whether personal income progressivity imposed on different levels of income effect economic growth similarly. This research contribute to the existing literature by examining the link between economic growth and progressivity imposed on low, medium and high levels of income earners separately. The research is carried out using dataset ranging from 2000 to 2013 and covering 34 OECD countries. The results of the analysis suggest that progressivity occurring at lower and higher levels of income has a negative effect on output growth, while progressivity at middle levels of income has a positive effect. Moreover, progressivity of personal income taxation has a positive effect on volatility of output growth, irrespective of whether progressivity occurs at lower, middle or higher level of income. Performed robustness tests confirms these findings
