This paper investigates how public policy responds to persistent ideological shifts in dynamic politico-economic equilibria. To this end, we develop a tractable model to analyze the dynamic interactions among public policy, individuals' intertemporal choice and the evolution of political constituency. Analytical solutions are obtained to characterize Markov perfect equilibria. Our main finding is that a right-wing ideology may increase the size of government. Data from a panel of 18 OECD countries confirm that after controlling for the partisan effect, there is a positive relationship between the right-wing political constituency and the government size. This is consistent with our theoretical prediction, but hard to explain by existing theories.
