A theoretical foundation for Constant Market Share analysis

Abstract: Abstract. Constant Market Share (CMS) analysis is a popular tool for analyzing changes in exports of a country. Nevertheless, its theoretical foundations (and policy relevance) have been questioned. In this paper, we provide such a foundation by relating CMS analysis to a two-stage homothetie demand model. An indication of the empirical relevance of this relationship is given by comparing the CMS analysis with a two-stage Constant Elasticity of Substitution demand model applied to 1972-1976 data of the Economi… Show more

“…4) the competitiveness term, an "unexplained" residual, reflects the difference between actual and hypothetical export increase if country A had maintained its share with regard to each commodity group. Merkies and Meer [9] define (i) to (iii) as the structural term, while (iv) as the competitiveness term. In contrast to the interpretation of such effects under structural term, the interpretation of competitiveness term is not as straight forward.…”

“…Assuming, in addition, uniform income elasticities of goods within a group, prices of goods outside the group will only affect real expenditure of the group (and not its composition). Following Merkies and van der Meer (1988), the scale and competitive effects can be expressed as follows:…”

“…A vital exposition of this method of analysis, specifically on the competitiveness term was provided by Richardson (1971). More critical expositions and theoretical arguments were put forth by Merkies and van der Meer (1988). Moreover, It has also been employed by a many authors to analyze the export performance of developing nations in terms of general competitiveness (Chen, Xu, & Duan, 2000;Juswanto & Mulyanti, 2003;Nalin Kumar & Muraleedharan, 2007;Thi Anh-Dao Tran et al, 2009;Gatto et al, 2011;Beltramello et al, 2012).…”
