PurposeDespite the growing body of empirical literature on earnings management in municipal bodies and enterprises on the municipal level, the theoretical foundations often remain limited. This article contributes to filling this research gap by discussing the agency relationships between entities, managers, politicians and the electorate based on the framework of political economy or, more specifically, economic theory of political action. It derives theoretical explanations for earnings management in municipally owned enterprises based on political-economic approaches and provides conceptual guidelines for further theoretical and empirical research in this field.Design/methodology/approachThe article discusses three specific theoretical approaches of political economy (political budget cycles/election cycles, interest fragmentation and partisan ideology) and applies them to the governance structures of municipally owned enterprises. For each of the perspectives, predictions about the use of earnings management and its possible motivations are derived.FindingsThe study shows that political budget cycles/election cycles, interest fragmentation and partisan ideology in municipal decision-making bodies can serve as possible explanations as to which extent managers of municipally owned enterprises present manipulated financial statements. All three approaches can help to explain the prevalence of earnings management but lead to different results regarding the methods and aims of earnings management.Originality/valueAs a significant portion of the current literature on earnings management in municipally owned enterprises lacks a theoretical foundation, our article aims to fill this caveat. To do so, we introduce three new conceptual perspectives that explain the prevalence of earnings management in such enterprises and the political-economic environments that are more likely to produce manipulated financial statements.
