A Panel Data Econometric Study of Corporate Tax Revenue in European Union: Structural, Cyclical Business and Institutional Determinants

This paper studies the economic determinants of corporate tax revenue to Gross Domestic Product (GDP) across European Union members over the period 1998-2009. The Feasible Generalized Least Squares (FGLS) regression results suggest that structural, cyclical, international and institutional factors such as GDP, Government Deficit, Industry Turnover, Unemployment, Number of Enterprises, Trade Openness, Foreign Direct Investment (FDI) and Corruption affect revenue performance of an economy. Thus, the findings show that Unemployment Rate and Corruption have an adverse effect on tax collection, while the other analysed factors contribute to a better performance concerning tax collection. In the present paper we also consider as explanatory factors the tax variables Effective Average Tax Rate (EATR) and Effective Marginal Tax Rate (EMTR). In fact, empirical results indicate a parabolic relationship between EMTR and corporate tax revenues, reinforcing the hypothesis of the existence of a Laffer curve. Our findings also suggest that the last two years of European Union enlargement are likely not to have had effect in corporate tax revenue to GDP. In addition, specific factors of some countries (Greece, Portugal and Spain) seem to positively affect corporate revenues.
