Determinants of economic corruption: a cross-country comparison

In recent years, the detrimental effects of bureaucratic corruption gained attention from development economists as well as international financial institutions and policymakers. Corruption, which was previously ignored and mentioned only with caution, has taken a center stage. Nonetheless, corruption is not a new phenomenon. Until recently the growth literature did not adequately explain why corruption is low in some countries and endemic in others. The relevant analytical problem is not to assess the harmfulness of corruption but why different political systems foster different levels of corruption. The empirical studies on the effects of corruption on economic growth are besieged by endogeneity problems. Few of these empirical studies take into account the possibility that economic growth or the lack of it can increase or decrease the level of corruption. This paper seeks to fill that gap by identifying the determinants of corruption and by examining the extent to which those factors - such as education, political regimes, the type of the state, ethnicity, judicial efficiency, political freedom, and the size of government - explain differences in corruption across countries.
