Currency appreciation by the creditor country will slow its economic growth and eventually cause deflation but cannot compensate for a saving-investment imbalance in the United States. Under a fixed exchange rate, however, differential adjustment in the rate of growth of money wages will more accurately reflect international differences in productivity growth. International competitiveness will be better balanced between high-growth and low-growth economies, as between Japan and the U.S. from 1950 to 1971 and China and the U.S. from 1994 to 2005, when the peripheral country＇s dollar exchange rate is fixed so that its wage growth better reflects its higher productivity growth. The qualified case for China moving toward greater flexibility in the form of a very narrow band for the yuan/dollar exchange rate, as a way of decentralizing foreign exchange transacting, is discussed.展开更多
