There are few areas in which public choice has had as much success in making inroads into mainstream economics and, in particular, in influencing real-life developments as in the design of monetary institutions and the day-to-day conduct of monetary policy. This survey tracks these developments, from the humble beginnings in the 1970s related to Nordhaus' (1975) account of the opportunistic political business cycle to the widespread academic and political discussion on monetary policy rules and targets of today.2 The next section contains a compact review of the two classical ideas in political macroeconomics, the political business cycle and the inflation bias. We then move on to more modern stochastic models, in which the desire for undistorted stabilization of supply shocks calls for refined remedies to the time-inconsistency problem, such as performance contracts and inflation targets for central banks. The following section moves on to a discussion of current developments that focus on instrument and targeting rules for monetary policy. Finally, we briefly assess these developments.
This paper provides a concise overview of the state of the art on monetary policy and central banking from a public choice perspective. It starts with a brief look at the roots of today's view of monetary policy conduct and the design of pertinent institutions in early work on political business cycles, and then proceeds to a discussion of the inflationstabilization dilemma along with proposed solutions in the form of central bank independence and conservativeness, incentive contracts, and inflation policy targets. The last section addresses current developments. These include the proper choice of monetary policy targets, the role of New Keynesian and sticky-information aggregate-supply curves and the quest for simple and efficient rules for monetary policy that has been triggered by the proposal and widespread polularity of the Taylor rule.
