Chapter 5 International Exchange System,第五章 国际汇率制度第一节 固定汇率制Fixed Rate SystemThe world economy operated under a system of fixed dollar exchange rates between the end of World War II and 1973,with central banks routinely trading foreign exchange to hold their exchange rates at internationally agreed levels.,Two kinds of the fixed exchange rates,金本位制度下的固定汇率制纸币流通制度下的固定汇率制Gold Standard:规定货币单位的含金量。含金量的的对比决定汇率。金币可以自由铸造；自由兑换；自由输出入。,The Gold Standard,An international gold standard avoids the asymmetry inherent in a reserve currency standard by avoiding the“Nth currency”problem.Under a gold standard,each country fixes the price of its currency in terms of gold by standing ready to trade domestic currency for gold whenever necessary to defend the official price.,Advantage of the Gold Standard,Because there are N currency and N prices of gold in terms of those currencies,no single country occupies a privileged position within the system:each is responsible for pegging its currencys price in terms of the official international reserve asset,gold.Gold standard rules also require each country to allow unhindered imports and exports of gold across its borders.,Benefits and drawbacks of the Gold Standard,Benefits:SymmetryPrice level and value of national money are more stable and predictableEnhance international transactions,Drawbacks:,Constraints on the use of monetary policy to fight unemployment.Tying currency values to gold ensures a stable overall price level only if the relative price of gold is stable.gold discovery in South AmericaAn international payments system based on gold is problematic because central banks cannot increase their holdings of international reserves as their economies grow unless there are continual new gold discoveries.The gold standard gives gold-producing countries power to influence the world economy,The Gold Exchange Standard,Halfway between the gold standard and a pure reserve currency standard is the gold exchange standard.Central banks reserves consist of gold and currencies whose prices in terms of gold are fixed,and each central bank fixes its exchange rate to a currency with a fixed gold price.More flexibility in the growth of international reserves.,Fixed Exchange Rates under currency-circulation system,纸币流通下的布雷顿森林体系。1944Bretton Woods

dollar was,in fact,originally set up as a gold exchange standard.While foreign central banks did the job of pegging exchange rates,the U.S.Federal Reserve was responsible for holding the dollar price of gold at$35 an ounce.By the mid-1960s,the system operated in practice more like a pure reserve currency system than a gold standard.President Nixon unilaterally severed the dollars link to gold in August 1971,shortly before the system of fixed dollar exchange rates was abandoned.,Floating Exchange Rate System,第二节

rate,浮动汇率制度的有利因素：可以防止大量游资对硬货币的冲击。可以防止外汇和黄金储备的流失。各国有较大的自由来推行本国政策。总而言之，没有义务来维护固定汇率。,Drawbacks of floating exchange rate,浮动汇率的三方面弊端：增加进出口贸易结算成本和风险，不利于国际贸易的发展。助长国际金融市场上的投机活动。各国采取以邻为壑政策，竞争性货币贬值。Beggar-thy-neighbor policy.,Krugman&Obstfeld(1),Discipline.Central banks freed from the obligation to fix their exchange rates might embark on inflationary policies.Destabilizing speculation and money market disturbances.Speculation on changes in exchange rates could lead to instability in foreign exchange markets.Injury to international trade and investment.Floating rates would make relative international prices more unpredictable.,Krugman&Obstfeld(2),4.Uncoordinated economic policies.The door would be opened to competitive currency practices harmful to the would economy.5.The illusion of greater autonomy.Floating exchange rates would not really give countries more policy autonomy.Changes in exchange rates would have such pervasive macroeconomic effects that central banks would feel compelled to intervene heavily in foreign exchange markets even without a formal commitment to peg.,Selection of Fixed&Floating Exchange Rates,固定汇率制和浮动汇率制的选择取决于一国的国情：大国还是小国；发展中国家还是发达国家；此事古难全,Exchange Rate System in Hong Kong,第三节 联系汇率制度（演变史）,Stabilization
