The role of ownership as R&D incentive in business groups

Several empirical papers have shown that firms belonging to business groups have a higher propensity to engage in R&D. The purpose of the paper is to demonstrate that this higher propensity depends on the ownership share of controlled companies, besides the presence of co-ordination mechanisms. We develop an analytical model and we empirically test the predictions of the model using a dataset of Italian manufacturing firms. From the development of this model we derive three main implications: a) that there is no difference in R&D propensity between stand-alone firms and firms at the bottom of business groups; b) that head and intermediate firms have a higher R&D propensity compared to stand-alone and firms at the bottom of the group; c) that the intensity of R&D depends on the ownership shares in controlled companies. Overall the results of the empirical analysis are in accordance with the implications of the model.
