This paper critically discusses the main contributions of the literature on the relationship between democratization and corruption, focusing on the perspective of how the former is expected to affect the latter and highlighting the different hypotheses and empirical findings presented by the most relevant and recent scholarly work in this line of research. Additionally, the discussion introduced here refers to a number of conceptual issues that remain obscure in the existing literature, with regards to the concept of both corruption and democratization, but at the same time stressing the gaps related to the latter, as to complement other contributions of the report that more thoroughly explore different conceptual approaches to corruption.
