Title: ”Complete Loss of Competition: Uncontested Elections and Political Rents”
Author: Naruki Notsu, Asahi Semma, Shuko Harada 
Abstract:This study examines how the complete absence of electoral competition shapes politicians’ behavior. To explore this, we focus on uncontested elections, which are common in democracies worldwide yet understudied. We develop a dynamic model with belief updating in which uncontested politicians lower their perceived risk of future challenge and raise their optimal salary. We test these predictions using the context of Japan’s uncontested elections, which operate under shared electoral institutions. We find that mayors who win office without a contest subsequently increase their salaries. The pattern also extends to pivotal stakeholders. The salary response is largest after the first uncontested win and smaller thereafter, consistent with belief convergence under learning. These findings suggest that when public conflicts, such as the existence of other candidates, do not exist, politicians are more likely to seek personal gain, highlighting the fundamental role of elections in disciplining officeholders.
