What is populism? An institutional economics approach with reference to Hungary

This paper conceptualizes populism in an institutional economics context. Examining the literature on populism in political science, it subscribes to the view that populism is a degraded form of democracy that holds elections in regular intervals as rituals of popular legitimation, but undermines pluralism and diminishes effective political choice. Based on the theory of transaction cost economics, the paper argues that populism is a form of government that reduces political uncertainties inherently present in liberal democracies, and hence mitigates political transaction costs. At times of crises and a mismatch between formal and informal institutions conditioning political exchange, demand for such a restricted form of democracy rises. This is what happened in Hungary towards the end of the 2000s, in a period characterized by fiscal stabilization and the socially costly impact of the global financial crisis.
