This paper explores the links between firms R&D investment decisions, and firms decisions on how much to sell at home and abroad in a heterogeneous-firm international oligopoly. The model provides analytical results that yield four testable hypotheses, which are empirically checked with data from the Spanish Survey on Business Strategies (ESEE) for the period 1992-2013. Our results confirm that exporters invest in R&D four times more than non-exporters in relative terms (Hypothesis H1). Our estimates confirm that past R&D intensity has a positive and significantly different effect on domestic and export outputs by exporters and that the effect on the rate of growth of exports is larger (H2). Econometric evidence suggests a positive and significant effect of appropriability on domestic sales, while a positive but non-significant effect on exports; thus partially confirming hypothesis H3. Finally, R&D efficiency measured as the propensity to obtain a patent or utility model is found to have a positive and significant effect on the rate of growth of exports, which confirms H4.
