Profit differentials and innovation

Economics of Innovation and New Technology, 2005, vol. 14, issue 1-2, pages 43-61

Abstract: The article aims to investigate empirically the effects of innovative activities on corporate profitability, using a panel of 267 UK manufacturing firms, over the period 1988-1992. Using the Bayesian approach to, explicitly, consider heterogeneity among firms, we find: (i) a positive and well-determined effect of innovation on profits that smoothly decreases as time passes by; (ii) a difference in profitability between innovators and non-innovators, greater when the comparison is between persistent innovators and non-innovators; and (iii) a long-run persistence in profit differentials. † E-mail: matteo.ciccarelli@ecb.int
