The gravity model and Portuguese exports in 2015
Abstract
Com a crescente e significativa abertura dos mercados, intensificou-se o negócio a nível internacional. Embora existam muitos fatores que encorajam o comércio transfronteiriço, ainda há alguns
obstáculos que atuam como uma barreira e devem ser eliminados.
O Modelo Gravitacional de Comércio é usado para explicar os fluxos comerciais entre dois países.
Considerando inicialmente que as exportações entre dois países estão positivamente associadas
ao tamanho das duas economias e negativamente relacionadas a fatores que indicam a existência
de barreiras ao comércio, dando maior ênfase à distância existente entre os países, o modelo foi
melhorado considerando outras variáveis.
Esta comunicação pretende utilizar o referido modelo gravitacional para compreender as razões
dos fluxos das exportações portuguesas e verificar se as variáveis gravitacionais mais comuns
têm um efeito semelhante sobre as exportações portuguesas, tal como acontece na maioria das
economias avançadas.
No presente estudo, esta ferramenta econométrica foi utilizada para analisar o volume das exportações
de Portugal para os seus principais parceiros comerciais internacionais em 2015.
With the increasing and significant opening of markets, business at international level has intensified. Although there are many factors that encourage trade across borders, there are still some obstacles that act as a barrier and must be eliminated. The Gravity Model of Trade is used to explain the trade flows between two countries. Considering initially that exports between two countries are positively associated with the size of the two economies and negatively related to factors that indicate the existence of barriers to trade, giving greater emphasis to the existing distance between countries, the model has been improved by considering other variables. This paper aims to utilize the referred gravitational model in order to understand the reasons behind Portuguese export flows and find out if the most common gravity variables have a similar effect on Portuguese exports as they do in most of the advanced economies. In this study, this econometric tool was used to analyze the volume of exports from Portugal to its main international trading partners in 2015.
