Why Does a Ruler Tolerate Corruption and How Can Corruption Possibly Be Eliminated?

Abstract

There is a fundamental conflict of interests between the ruler and most citizens in non-democracies. When the ruler maximizes his benefit from taxation, the major constraint is that citizens might make attempts to overthrow the existing regime. The continuity and stability of regime are crucially related to the degree of support to the existing political regime by the bureaucracy. In this paper, we use a simple model to argue that, when the ruler maximizes his benefit and faces exogenous restriction on wage setting, toleration of corruption is necessary to induce the required support and effort from the bureaucracy. We then relax the exogenous restriction on wages and study the case in which the ruler may eliminate corruption by setting efficiency wage. We also explore the possibility that the ruler may use an audit device to check corruption.
