Central bank design in general equilibrium

We study the effects of alternative institutional arrangements for the determination of monetary policy in the context of a capital-theoretic, general equilibrium economy. In the absence of an institutional arrangement, there is a continuum of steady state equilibria indexed by rates of inflation ranging from the Friedman rule to high a high level. The social optimum is associated with the Friedman rule.. We consider three institutional arrangements for determining monetary policy. The first, unconditional majority voting, always leads to a substantial inflation bias. The second, a simple form of bargaining which we interpret as a policy board, generally improves on the unconditional majority voting outcome. Finally, we consider a form of constitutional rule which always achieves the social optimum.
