In previous research, we analysed the effect of technological innovation, understood as absorptive capacity, on exports by using a gravity model of trade for the year 2000 (see Márquez-Ramos and Martínez-Zarzoso, 2009). We found that the effect of technological innovation on trade varies...

Nonlinear estimation of the gravity model with Poisson/negative binomial methods has become popular to model international trade flows, as it permits a better accounting for large numbers of zero flows. Nevertheless, as trade flows are not independent of each other due to spatial...
