Descrição

This study examines the evolution of Portuguese exports to Spain and its determinants in the period 2004-2008, based on a sample of the 97 largest exporters to Spain. The econometric study, using panel data and a static and dynamic analysis, considers as theoretically relevant explanatory variables productivity, equity capital, remuneration and innovation measured by the expenditure on research and development (R&D). The static results of the estimated models confirm the positive influence of productivity and equity capital on the variation of exports, and the negative effect of the labour costs. The variable R&D is statistically significant, with a positive effect on Portuguese exports in the dynamic model. The dynamic estimations also suggest that the exports in the previous period have a positive effect on contemporaneous exports.
