The "Invisible Role" of Business Groups is made Evident

Business Groups collect and coordinate legally autonomous firms spanning both within and across national borders . They represent a lion's share of value added generation on a world scale, and yet they received little attention in economics literature, probably due to a lack of detailed data. In Altomonte and Rungi (2013) we exploited a unique own-built dataset of proprietary linkages to find that: a) Business Groups are present in both developing and developed countries, adapting their organization according to the peculiarities of the hosting environment; b) within Business Groups, choices of integration of production activities are not independent from choices of management coordination; c) eventually, choices of management coordination reveal to be important drivers of productivity and dominate on choices of vertical integration. More in general, here we argue, data are telling us that the adoption of different organizational structures at the firm level can in part explain the endurance of productivity gaps across industries and countries and the phenomenon of Business Groups becomes even more important after the emergence of Global Value Chains.
