Currency of denomination and the measurement of export instability
研究了66个发展中国家的数据，发现以美元计价出口收入的传统方法并无严重缺陷，而选择合适的趋势修正形式更为重要。
The widespread and unexpected absence of statistically significant relationships in analyses of the causes and consequences of export instability has generated attempts to refine measurement of variable sets. Recently it has been suggested that country rankings are sensitive to the choice of currency numeraire. This article investigates the significance of the choice of numeraire for a sample of 66 developing countries. The results suggest that the conventional approach of denominating export earnings in terms of US dollars is not seriously deficient and that the selection of an appropriate form of trend correction remains an important consideration.
