Within this respective, a panel consisting of 35 OECD member and other countries is analysed with dynamic panel threshold regressions and bootstrap threshold testing methodologies for the 1992-2016 period. The results reveal significant threshold effects of the economic growth rates closely followed by the threshold effects dominated by the share of R&D in the GDP. The empirical findings have significant contributions: i. the impacts of high technology exports are asymmetric and regime-dependent, in addition, positive in both regimes, ii. R&D expenditures have positive effects not only in the high R&D/GDP but also in relatively low R&D/GDP and growth regimes, iii. the R&D in GDP threshold parameter is estimated as close to 0.7% and is compared to the literature. The overall findings coincide with the endogenous growth literature, but with an interesting distinction regarding the positive impacts even at low R&D regimes. The policy suggestions favor the encouragement of R&D and its positive effects on economic growth even for countries that cannot achieve a theoretical 3% R&D in GDP threshold.eninfo:eu-repo/semantics/closedAccessinnovationhigh technology exportseconomic growth in open economiesthreshold modelsArticle2-s2.0-85128666982441Q32625WOS:000784739600002Q4
