Mean field game model of corruption

TL;DR

This paper introduces an exactly solvable mean-field game model of corruption that captures how social interactions and norms influence the spread of corrupt behavior among large populations.

Contribution

It presents a novel, analytically solvable mean-field game model incorporating social interactions and norms affecting corruption dynamics.

Findings

Interaction influences corruption spread

Social norms impact agent decisions

Model is exactly solvable and analytically tractable

Abstract

A simple model of corruption that takes into account the effect of the interaction of a large number of agents by both rational decision making and myopic behavior is developed. Its stationary version turns out to be a rare example of an exactly solvable model of mean-field-game type. The results show clearly how the presence of interaction (including social norms) influences the spread of corruption.
