Heterogeneity and divergence in local innovation systems. Some empirical evidence from Argentinean SMEs
Congreso; Globelics; 2013
Two of the most common characteristics of capitalist production structures are the heterogeneity of productive performance at the firm level and the divergence in the productive performance of local innovation systems. In this paper, I address this characteristic of productive systems by estimating the presence of externalities within reference groups that are made up of firms from the same sector and geographical area in a balanced panel of 1200 Argentinean SMEs. I propose a social interactions model (Schelling, 1971; Durlauf, 1993, 2003 and 2005; Glaeser and Sheikman, 2001) where the productivity of each firm will depend on that of the reference group discarding its own productive performance. Considering the presence of heterogeneity inside local systems, I estimate the different impact of these externalities on firms with different capabilities and linkages. On the other hand, taking into account divergence between local systems, I estimate the presence of a social multiplier (Glaeser et al, 2003), derived from systemic interactions which lead to an amplification of individual responses and therefore the divergence between systems.
