This paper examines the data sources and methodologies used in economic research on corruption by analyzing 339 journal articles published in 2022 that include Journal of Economic Literature codes. The paper identifies the most commonly used data types, sources, and geographical foci, as well as whether studies primarily investigate the causes or consequences of corruption. Cross-country composite indicators remain the dominant measure, while single country studies more frequently utilize administrative data. Articles in ranked journals are more likely to employ administrative and experimental data and focus on the causes of corruption. The broader dataset of 882 articles highlights the significant academic interest in corruption across disciplines, particularly in political science and public policy. The findings raise concerns about the limited use of novel data sources and the relative neglect of research on the causes of corruption, underscoring the need for a more integrated approach within the field of economics.
