Corruption has received significant attention among economists and international financial institutions during the last few decades, given its implications for economic growth. In this paper the authors will analyze and present: First, list a number of possible causes and consequences of corruption, derived from a review of the recent empirical and theoretical literature. Second, propose a model that can help explain the relationship between corruption and the economic growth. In the third section, the authors will introduce several measures of corruption, certain empirical correlations and their policy implications, we will then conclude in the last section.
