This document is an abstract for a conference presentation on defining and controlling corruption. It discusses how corruption has been defined in various ways internationally and domestically in Nigeria. The presentation aims to develop a better understanding of how to curb corruption across different fields, strengthen ethics for public officials, and improve the conceptual clarity around the offense of corruption to increase conviction rates. It argues that not all economic crimes constitute corruption, and corruption involves a public official acting in violation of the law for personal gain. A global definition of corruption does not fully capture its multi-disciplinary nature. The presentation will evaluate the existing Nigerian laws around corruption and their effectiveness.
