Productive diversity, technology spillover sectors, and regional performance in Argentina between 2008 and 2018

Abstract

This paper empirically analyzes the incidence of productive diversification on regional performance in Argentina between 2008 and 2018. Assuming that spillovers between productive activities requires proximity in the knowledge base, a distinction is made between related and unrelated productive diversification, which are estimated using entropy indicators. Econometric estimations are performed to explain the dynamics of employment and wages (as proxy for productivity) by the levels of related and unrelated regional diversification. Findings suggest that related diversification has a positive impact on employment and wage dynamics at the regional level, while unrelated diversification contributes to maintaining regional employment during macroeconomic contractions. No empirical evidence is found supporting that general purpose technology (such as mechanical engineering and ICTs) enhances the effects of related diversification on regional performance. It is observed, however, that the software sector enables the presence of externalities between technologically distant activities.
