The Philippine mango global value chain: An empirical study using the gravity model approach
Michael Fernandez Centino & Mary Caroline Castano

Abstract
To maintain the Philippines’ competitive edge in the trading of agricultural products, this study identifies factors that significantly influence the Philippines’ participation in the mango global value chain. The study employs a causal research design with panel regression analysis using pooled regression, a fixed effect model and a random effects model and determines the robustness of the models using the Hausman test. The resulting fixed effect model reveals that gross domestic product, remoteness and global competitiveness have a significant positive effect on gross exports and value-added, while being land-locked and bilateral distance have a significant negative effect. Among the identified variables, remoteness has the greatest influence. The resulting model is limited to the analysis of the Philippine mango global chain’s integration in terms of gross exports and value-added contribution to the economy of the country. The underlying factors not included in the model are not given emphasis. This study identifies the factors that correctly estimate the Philippines’ mango global integration. The policy recommendations, if implemented, can guarantee strong integration of Philippine mangoes in the global chain, which will facilitate the flow of factor payments in the economy, thereby raising the standard of living of Philippine citizens and creating more social protection for the Philippine people. Previous studies have been conducted describing the Philippine global value chain integration, but these studies are limited in that they use descriptive analysis and did not identify the factor/s that will improve the mango global value chain’s integration.
