In this paper, we analyze the interaction between corruption, taxation and economic growth. Our contributions are twofold. Theoretically, in an endogenous growth model, we introduce corruption in two different ways: corruption in the public expenditure and corruption in the public revenue. We show two opposing effects. Under certain conditions, corruption can affect growth rate positively but it can also exert a negative effect via fiscal revenue. Not only does it tend to make the tax rate, which maximizes the long run growth rate sub-optimal, but it can also create distortions that can lead to excessive tax rates harmful to growth.
The empirical analyses are based on non parametric estimates as well as econometric investigations. Our results support the assumption of a non linear relationship between public resources and growth. Interactions between public resources and institutional variables evidence the following the results: (i) the more countries are corrupt the stronger the negative effects of taxation on the growth (ii) Once the negative effects of corruption are accounted for, our data do not support a potential positive effect of corruption on economic growth.
