具有粘性名义价格的一般均衡优化模型使我们能够重新审视开放经济中的最优货币政策问题。如果名义价格是以生产者的货币确定的,适当的货币政策可以在灵活的价格下重现分配。如果名义价格是以消费者的货币确定的,稳定的名义汇率可能是可取的。在这种情况下,固定在购买力平价水平上的名义汇率可以对风险分担产生理想的结果,而名义汇率的灵活性不能带来最佳的相对价格变化。然而,有证据表明,对进口价格的转嫁可能大于对消费价格的转嫁。如果对消费者来说价格是固定的,但进口分销商面临转嫁,那么货币政策制定者面临一种权衡,可能需要对名义汇率进行一定程度的控制,但不是纯粹的固定汇率。版权所有2002年由布莱克威尔出版有限公司和曼彻斯特维多利亚大学
General equilibrium optimizing models with sticky nominal prices allow us to revisit questions about optimal monetary policy in open economies. If nominal prices are set in producers' currencies, appropriate monetary policy can reproduce the allocations under flexible prices. If nominal prices are set in consumers' currencies, stable nominal exchange rates may be desirable. In this case, a nominal exchange rate fixed at the PPP level can have desirable consequences for risk sharing, and nominal exchange rate flexibility cannot deliver optimal relative price changes. However, evidence shows that pass-through may be greater to import prices than to consumer prices. If prices are fixed for consumers, but importer-distributors face pass-through, then monetary policy makers face a trade-off that might require some control of nominal exchange rates, but not purely fixed rates.
