Corruption is an ancient phenomenon that weakens all functions of the government, directly affects its monetary and fiscal policies, and causes permanent social and economic problems by disrupting human capital. Corruption can cause structural problems (e.g., unemployment, unfair distribution of income) to deepen, slow economic growth, weaken human development and lead to insecurity and social unrest. Statistical analysis of this concept, which is of great economic significance, is an important source of motivation for the present study. The current study aims to categorize the nations based on corruption levels and to identify the discriminating economic variables effective in this categorization. Thus, various economic variables that affect the level of corruption in OECD countries, including Turkey, are evaluated. The 2013 data for the thirty-four countries are tested using discriminant analysis in the study. The results indicate that in OECD members with low HDI, GDP per capita and education expenditures, and high unemployment, the level of corruption is at a higher level.
