Abstract

ABSTRACT: Chami’s method for calculating how much of an exporter market share change can be attributed to each competitor has regularly been applied in the literature, but has not been related to any theory yet. Here, an attempt is made to examine the trade models that can provide the theoretical foundations for the method, clarifying the assumptions underlying its results. It is shown that the method is consistent with most of the main trade models found in the literature.

RESUMO: O método desenvolvido por Chami para distribuir as participações de cada país exportador entre seus competidores em um determinado mercado tem sido aplicado na literatura, mas ainda não foi associado a qualquer teoria. Este artigo procura examinar os modelos de comércio que podem oferecer os fundamentos teóricos para o método, clarificando as suposições necessárias aos seus resultados. Mostra-se que o método é consistente com a maioria dos principais modelos de comércio encontrados na literatura.
