Fontes de variação n o valor das exportações brasileiras de lagosta: uma aplicação do método shift-share

Abstract

The behavior of the value of exports of a particular good is an important indication of its conditions of generation of foreign exchange, employment, income and welfare for the exporting country. This study analyzed the behavior of the values of Brazilian exports of frozen whole lobsters. To decompose the value of exports in quantity effects, price and destination country we used the shift-share. The variations in the quantity exported were decomposed into scale effect and substitution effect. It was found that between 1990 and 2015 there was a decline in the value of exports, explained by the quantity effect. The quantity exported fell in the three main destination countries, the United States, France and Japan. However, the substitution effect indicates that the United States has reduced its share in Brazilian imports, replaced by France and Japan.
