A new approach to estimation of the R&D–innovation–productivity relationship

Abstract: We apply a generalized structural equation model approach to the estimation of the relationship between R&D, innovation and productivity that focuses on the potentially crucial heterogeneity across sectors. The model accounts for selectivity and handles the endogeneity of this relationship in a recursive framework which allows for feedback effects from productivity to future R&D investment. Our approach enables the estimation of the different equations as one system, allowing the coefficients to differ across … Show more

“…In order to formally show the role of the innovative milieu in a region for innovation persistency of a firm located in that region, we start with the classic knowledge production function (KPF). The KPF relates the innovation outputs to the innovation inputs (Griliches ; Crépon et al ; Baum et al ): Yi=AiHiαKiβ, where Y i is a measure of the innovation output in firm i (for simplicity, let us assume it is a binary measure), A i measures the overall labour productivity of the innovation activities in firm i , H i is the human capital input in innovative activities in firm i , and K i represents all other internal innovation inputs in firm i . Here a clear distinction is made between the innovation output and the innovation inputs.…”

“…The findings are robust: we find a significant positive correlation between operational efficiency and Patent assets & Intellectual Property Rights, Goodwill, and Trademarks & Licenses, while we cannot confirm the correlation with reference to Research & Development Capital (and Advertising investments) (although theoretically meaning advances of knowledge and productivity; Pakes & Griliches, 1984;Baum et al, 2017). As a consequence, in this turbulent context, most intellectual assets (the former group, especially trademarks & licenses, and goodwill, whose coefficients are more confidently positive) appear from the efficiency point of view, more reliable than the remaining ones (the latter class) in hampering the profitability drop (ROA and ROE are negative).…”

“…There is strong empirical literature demonstrating the positive impact of innovation on firm productivity. See, for example, Baum et al (2015), Mohnen and Hall (2013), Siedschlag and Zhang (2015) and Bartel, Ichniowski and Shaw (2005).…”
