Twenty-five years of accountability research in public administration: Authorship, themes, methods, and future trends

There is extensive literature on accountability, yet systematic research on the state of the art in the field of public administration is lacking. This research is essential to understand the aspects of accountability that have been studied and identify the primary findings and areas that require further investigation. This study seeks to address this gap by conducting a systematic literature review of 277 articles on accountability published in 15 leading public administration journals between 1996 and 2021. This review aims to answer the following questions: What types of accountability have been examined? To what extent has accountability been investigated as a dependent or an explanatory variable? Which methodological approaches dominate, and which cases are more commonly examined? What are the current challenges and future research trends?
