Replacement and Reputation

AI Summary

Can electoral turnover ensure long-term accountability of officials? This paper develops a dynamic Bayesian game model in which voters decide on reappointment or removal based on observed performance, while politicians are either “virtuous” or opportunistic. Through reputation modeling, type discrimination, and equilibrium analysis, the study identifies how economic conditions affect accountability efficacy: under incentive compatibility, a sustained-effort “incentive-driven” equilibrium is supported; otherwise, good governance relies on voter screening—yielding a “selection-driven” equilibrium. The paper provides the first rigorous distinction between these two equilibrium pathways, precisely characterizing their existence conditions and robustness boundaries. It further proves that desirable long-run governance outcomes are always attainable—contingent critically on whether the institutional environment permits credible reputation accumulation. The analysis thus clarifies the mechanisms through which electoral institutions foster accountability, highlighting the interplay among incentives, information, and institutional credibility in sustaining political effort.

Abstract

Does electoral replacement ensure that officeholders eventually act in voters' interests? We study a reputational model of accountability. Voters observe incumbents' performance and decide whether to replace them. Politicians may be "good" types who always exert effort or opportunists who may shirk. We find that good long-run outcomes are always attainable, though the mechanism and its robustness depend on economic conditions. In environments conducive to incentive provision, some equilibria feature sustained effort, yet others exhibit some long-run shirking. In the complementary case, opportunists are never fully disciplined, but selection dominates: every equilibrium eventually settles on a good politician, yielding permanent effort.

Problem

• Investigates if electoral replacement ensures politicians act in voters' interests.
• Examines reputational accountability with good and opportunistic politician types.
• Analyzes how economic conditions affect long-run outcomes and politician discipline.

Innovation

• Reputational model studies electoral accountability mechanisms
• Equilibria analysis reveals sustained effort or shirking outcomes
• Selection dominates in disciplining opportunists under certain conditions
