摘要:	It is well-known that there are unique challenges to design optimal monetary policy in an open economy since an e?ort by one country's expansionary policy to in?ate may depreciate its currency, which in- duces greater domestic in?ation through the real exchange rate chan- nel. Due to the existence of the above tempering e?ect of the real exchange rate channel, monetary authorities under non-coordination realize that lowering unemployment is more costly. With coordinated policy, however, policymakers are more likely to in?ate since the in- ?uence of tempering is removed. To investigate the impact of an ex- ogenous change in the natural rate of unemployment on the optimal time consistent monetary policy regarding in?ation bias, we present a two-country framework to compare the minimal-state-variable ra- tional expectations equilibria under three di?erent scenarios: coor- dination, non-coordination, and leader-follower regimes. The theory demonstrates that, under either coordination or non-coordination, a rise in one country's natural rate of unemployment will lead its own in?ation to increase if the e?ect of unanticipated in?ation surprises is stronger than the e?ect of the real exchange rate channel. Moreover, we suggest that the international interactions of the natural rate of unemployment and the MSV REE in?ation depends on the design of the exchange rate regime. Furthermore, the potential gains to coun- tries coordinating exchange rate policy depend on the relative degrees of in?ation bias between the two economies.
