International Financial Adjustment
研究一国外部约束对净外国资产、回报率和汇率动态的影响，发现估值效应贡献了周期性外部调整的27%，并具有资产定价含义。
We explore the implications of a country's external constraint for the dynamics of net foreign assets, returns, and exchange rates. Deteriorations in external accounts imply future trade surpluses (trade channel) or excess returns on the net foreign portfolio (valuation channel). Using a new data set on U.S. gross external positions, we find that stabilizing valuation effects contribute 27 percent of the cyclical external adjustment. Our approach has asset-pricing implications: external imbalances predict net foreign portfolio returns one quarter to two years ahead and net export growth at longer horizons. The exchange rate is forecastable in and out of sample at one quarter and beyond. (c) 2007 by The University of Chicago. All rights reserved.
