Determinantes das Exportações de Castanha de Caju da Guiné-Bissau (1986-2011): uma análise sob a ótica do modelo de gravidade de Bergstrand

Abstract

Resumo: Este trabalho analisa os determinantes das exportações de castanha de caju da Guiné-Bissau para a Índia no período de 1986-2011, utilizando o modelo de gravidade de Bergstrand (1985). Os resultados reportados do modelo de dados em painel (MQO-pooled) sugerem, por um lado, que o fluxo de exportações de castanha de caju é negativamente relacionado com o custo de transporte e, por outro, positivamente relacionado com a taxa de câmbio e rendas brutas e per capita, o que é consistente com os pressupostos teóricos dos modelos gravitacionais e com os estudos seminais da literatura econômica com a aplicação desses modelos.

Expansion of Cashew Cultivation and its Environmental and Economic Impacts on Guinea-Bissau

“…It is also a variable that impacts on exports, as it affects the price of the final product. In the study by Cateia et al (2018), the reported results of the panel data model (OLS-pooled) suggest, on the one hand, that the flow of cashew nut exports is positively related to the exchange rate and gross and per capita incomes, which is consistent with the theoretical assumptions of gravitational models and with the seminal studies of economic literature on the application of these models. However, in this study, it was observed that TC is a variable; despite having an R² value of 14.6%, it presented an individual significance value of 0.12, which is an indication that its variation would not have affected the CNSE.…”

“…Cashew is a perennial tree species belonging to the Anacardiaceae family and to the Anacardium genus (Catarino et al, 2015;FAO, 2020). It is mainly grown in tropical countries, especially in Brazil, Vietnam, India and the Ivory Coast (Dendena and Corsi, 2014;Elakkiya et al, 2017), Nigeria, Indonesia, Philippines and Benin (FAOSTAT, 2020), and Guinea-Bissau (Catarino et al, 2015;Cateia et al, 2018). Brazil, India, and Vietnam are the world's largest processors.…”
