Corruption is a widespread phenomenon affecting all societies to different degrees, at different times and it is considered as major obstacle in economic development. This paper studies the empirical literature on the sources of corruption. Due to data availability for the OECD countries I am able to produce cross-country econometric model to test hypothesis of corruption determinants. This study takes into consideration various determinants of corruption for 32 countries using panel data for the period 2010 to 2014. In examining various hypothesis this study attempts to answer whether first corruption is lower in countries with higher economic growth rate or not. The second hypothesis is whether schooling (education) has any impact on corruption or not? Third is whether a county in which unemployment is more also has more corruption. Fourth is to find out the relation between trade openness and corruption. Fifth is political instability leads to more corruption in country or not. Sixth is whether strong governance indicators (voice and accountability, government effectiveness, regulatory quality, rule of law) lead to less corruption in a country or not?
