abstract

The hypothesis that when the imitation risk is supported from exports then the decision to patent abroad is intensified is coming under scrutiny in the present paper, using data from 28 OECD countries. We investigate this issue, via two routes: the full sample for all source countries and a group-based. Higher exports increase the impact of imitation risk in the destination country on patenting abroad. The impact is positively correlated with the source country's size. Business cycle impact is statistically significant and positive but the counter intuitive sign of the IPR regime in the destination country demands further investigation. Finally, the distance variable is statistically significant and negative, verifying gravity model.

4. Empirical results and discussion

Table 3 presents a summary of the estimation results: the full set of our sample countries, the group of “big” countries and the group of “small and medium” ones. The econometric estimation followed was the panel random effects (RE) for the full sample, the “small and medium” countries and the “big” countries group. We report two modes for each set (the full sample, the group of “small and medium” counties, and the group of “big”); the Mode 1 without the interaction term and the Mode 2 with the interaction term. We note that we have also lagged our right hand side variables LHOST and LEXP (and as a result their product, i.e. the INTER variable, as well) one period to control for the possible endogeneity of current values of the explanatory variables (see also Bloom and Van Reenen, 2002). As a result, this change does not noticeably affect the previous results reported in the main body of the paper.
