摘要：This paper focuses on the noncooperative policy game specified by choice of policy instrument for implementing optimal monetary policy in a two-country dynamic stochastic general equilibrium model. It examines four options of policy instruments including the producer price index inflation rate, the consumer price index inflation rate, the import price inflation rate and the nominal interest rate. It shows that choosing different policy instruments generally leads to different equilibria and, in particular, choosing the nominal interest rate results in equilibrium indeterminacy. In addition, the welfare ranking of these policy instruments depends on a country’s degree of openness which is measured as the weight assigned to imported goods in the consumers’ utility function in consumption. In less open countries, domestically produced goods carry a relatively higher weight. For these less open countries, choosing the producer price index inflation rate induces a larger welfare cost from noncooperation than choosing the consumer price index inflation rate would. Choosing the consumer price index inflation rate in turn causes a larger welfare cost than choosing the import price inflation rate. Conversely, the reverse is true when countries are more open. These results shed light on the important role that choice of policy instrument plays in determining the equilibrium outcomes, to which policy makers should pay special attention when implementing optimal monetary policy under noncooperation.
