On measurement of export instability: an innovative index. (English) Zbl 1133.91527

Summary: Instability in export performances may be caused by a variety of market forces both short-term and long-term. Fluctuations may be caused by upward or downward turn of export performances or may be due to their combined effect. When such fluctuations upset the export target, it may become a serious concern of the export-planners. But, unfortunately, the present methodologies fail to segregate the downward or negative pulling effect of export performance. The present paper aims at developing a quantitative tool for measuring export-instability based on upward and downward turn of export performance and which is capable of quantifying instability on a year-to-year basis.
