Comparison of excess social rates of return to product and process R&D

This paper reports results for a well established production function that includes research and development (R&D). By assuming zero depreciation, it can be used to provide estimates of excess social rates of return to R&D. The estimates distinguish spending on product and process innovations for three US manufacturing industries. The results suggest that, while excess social rates of return are found to be negative for product R&D, they are positive for process in each of the industries. They therefore suggest some scope for public R&D subsidies or tax benefits to process R&D but not to product R&D.     

Effects of coordinated strategies on product and process R&;D

Using a game theoretical model on firms’ simultaneous investments in product and process R&D, we advance and empirically test hypotheses on the role of externalities on the optimal R&D portfolio of cooperating firms and independently competing firms. We use Community Innovation Survey data on 3,696 Italian manufacturing firms. In line with our model we find that members of a group of firms invest significantly more into product, process, and aggregate R&D than independent firms. Further, their R&D portfolios tend to show a higher product versus process ratio. However, with regard to R&D performance and efficiency we find that independent firms are superior.      

R&D strategy and innovation performance: the role of standardization

Firms now increasingly recognise the important role of R&D strategy in building technological advantage. However, few attempts have linked standardisation with specific R&D strategies in explaining innovation performance. To bridge this gap, this study empirically examines the relationships between R&D strategies, standardisation, and firms’ innovation performance. Based on a sample of 371 firms in China, we use structural equation modelling (SEM) and find that novelty-oriented R&D strategy generates greater accumulation of standardisation knowledge and standards diversity, while R&D openness only positively relates to this standardisation knowledge accumulation. Moreover, standardisation knowledge accumulation is positively related to both administrative and technical innovation performance, while a greater variety of standards only leads to higher administrative innovativeness. More importantly, our results reveal that accumulation of standardisation knowledge mediates the relationships between R&D novelty and administrative and technical innovation performances. Both the theoretical and practical implications that arise from these findings are discussed.     

Vertical educational diversity and innovation performance

This paper uses panel data of Swiss firms to analyse the impact of education-level diversity in the workforce on innovation performance, addressing endogeneity by exploiting within-firm variation as well as variation in labour supply across regions. We find that vertical educational diversity increases the extensive margin of R&D and product innovation, particularly new product innovation. However, the relationship with process innovation, R&D intensity, and product innovation intensity is insignificant. These results are in line with the idea that vertical educational diversity enhances the creative moment of the invention phase, while it has no effect on the commercialization phase due to the relevance of coordination and communication costs relative to the gains in creativity.     

Complementarity between product and process innovation in a monopoly setting

In this article we study complementarity between market-enhancing product innovation and cost-reducing process innovation in a monopoly setting. First, we consider the possibility for a firm to alternatively invest only along one of the two directions and compare the incentives of process vs. product innovation. Then, we allow the firm to invest simultaneously in both activities, showing that both investment levels and profit are higher than in the case of individual investment. Thus, product and process innovations are complementary, and the firm always prefers the simultaneous adoption of both activities.     

Measuring innovation in long product development cycle industries: an insight in biotechnology

This paper examines and measures innovation in the context of biotechnology firms by analysing the link between R&D, innovation performance and organisational growth. We conceptualise innovation performance as a latent construct with two dimensions: innovation efficacy and innovation efficiency. We use structural equations modelling to test the hypotheses on a data set from the biotechnology industry. Results support our innovation performance conceptualisation which is found to be especially useful to measure innovation in industries with long product development cycles. Findings also underline the importance of R&D knowledge creation for biotechnology firms.     

A Microeconometric note on product innovation and product innovation advertising

This paper seeks to explain why more than half of the German service sector firms that introduce a product innovations do not advertise their new or markedly improved product. One part of the explanation is that they do not need to advertise because they are closely related to their customers anyway, and another part of the explanation is that product innovation and product innovation advertising are strategic substitutes.     

Product innovation,process innovation and export propensity: persistence,complementarities and feedback effects in Spanish firms

Drawing on a longitudinal data of Spanish manufacturing firms, this study explores the persistence of technological innovation and exports, their potential complementary relations and feedback effects. Empirical results suggest the presence of both true and spurious state dependence in all three activities. True state dependence in technical innovation and exports implies intertemporal spillovers relevant to the evaluation of innovation and export policy measures. However, given that results also suggest spurious state dependence, firm-specific characteristics should be taken into account in promoting technological innovations and exports. In addition, we find a strong complementarity between product and process innovation both through a contemporaneous effect and via unobserved firm characteristics. However, concerning complementarity between innovation and exports, results suggests complementarity only through contemporaneous effects. Finally, we find no support for the causal link from past product and process innovations to current export activities.     

Impact of organizational innovation on product and process innovation

The purpose of this paper was to test the effect of organizational innovation on product and process innovation (while controlling for endogeneity). Our hypothesis was that organizational innovation should have a significant and positive impact on technical (product or process) innovation. We control for endogeneity by using a Poisson estimator that accommodates a binary endogenous regressor. We test 10 potential instruments using a battery of test criteria and settle on five. All results are presented using the five instruments to avoid expectation bias. In general we find that organizational innovation does impact technical innovation positively. With the 2009 data we find that the mean of the average treatment effect for product innovation is roughly 1.7 times that of process innovation. For the 2009–2012 data we find that the impact on product innovation is roughly 1.5 times that of process innovation. For the 2012 data, we had anomalous results for process innovation, such that organizational innovation reduced the number of process innovations by 2.3 per year. In terms of Canadian government policy, the results lend support to the view that technical innovation is not the only innovation that matters. The right policy mix may encourage firms to experiment with and adopt more organizational innovations to enhance technical innovation.     

Types of cooperation partners as determinants of innovation failures

In this paper we analyse if specific R&D cooperation partners are related to an increase in the probability of innovation failures in terms discontinuing innovation projects. We distinguish between seven different R&D cooperation partner types, and we discriminate between product innovation failures and process innovation failures. Using German Community Innovation Survey data we find that, firstly, each type of R&D cooperation partner has a different effect on innovation failures. Secondly, we show that product innovation failures and process innovation failures are not affected in equal measure by the same type of R&D cooperation partner. Our results suggest that while R&D cooperation with public research institutes is significantly and negatively related to the probability to cancel a process innovation project, the coefficient is positive but insignificant for product innovation failures. Firms conducting partnerships with suppliers, however, run the risk of both product and process innovation failures. In turn, cooperation with competitors is positively correlated only to process innovation failures.     

The impact of R&D subsidy on innovation: evidence from New Zealand firms

This study examines the impact of government subsidy through R&D grants on innovation output for firms in New Zealand. Using a large database that links administrative and tax data with survey data, we find that R&D grants have a stronger effect on more novel innovation (e.g. applying for a patent or introducing new products to the world) than on incremental innovation (e.g. any product innovation) and that larger, project-based grants are more effective at promoting innovation than smaller, non-project-specific grants. There is little evidence that R&D grants have differential effects between smaller (<50 employees) and larger firms.     

Matching public support for private product-innovating R&D: a theoretical analysis

This paper develops a theoretical model of product innovation where research and development (R&D) effort by a monopolist firm is endogenous and its outcome uncertain. The government attempts to aid such efforts with a matching grant. We consider different scenarios depending on whether two parties act simultaneously, act sequentially, or take part in a dynamic cooperative game with a trigger strategy. We also consider cases (i) when the products are exported, (ii) when the firm lobbies for R&D subsidy, and (iii) when the firm is foreign owned. We characterize situations when government intervention increases the chances of product innovation and when it does not.     

Strategic R&D and the innovation of products: understanding the role of time preferences and product differentiation

We evaluate the effects of innovation on competition using an optimal control approach that incorporates firms' time preferences. Using a model where firm(s) innovates by investing in research and development to create a more appealing product for heterogeneous consumers, we examine conditions that maximize social welfare. When firm(s) choose discount rate regardless of market structure, a monopoly will develop more innovative products. However, we show that duopolies may increase innovation if competition alters firms' outlook. Finally, we identify firm incentives to behave myopically, which in the context of collusion may impede industry-wide innovation.     

Battle royal in biotechnology: R&D vs. product vs. process innovations

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market.     

The Damoclean tax and innovation

The paper presents a novel tax that is designed to improve the performance of research and development (R&D) investments. Ideally, the tax allows the technical efficiencies of monopoly while bringing about the desirable effects of the competitive pressure of R&D rivalry. Thus, with the tax, the state can sanction a monopoly of R&D investment in order to attain technical efficiencies and yet avoid the underinvestment in R&D that would result without competitive pressures. A critique of the tax emphasizes the problems of implementing it and offers a more practical alternative that would achieve the same desirable effects.     

Evidence on the impact of R&D and ICT investments on innovation and productivity in Italian firms

Both research and development (R&D) and information and communication technology (ICT) investment have been identified as sources of relative innovation underperformance in Europe vis-à-vis the USA. In this article, we investigate the R&D and ICT investment at the firm level in an effort to assess their relative importance and to what extent they are complements or substitutes. We use data on a large unbalanced panel data sample of Italian manufacturing firms constructed from four consecutive waves of a survey of manufacturing firms, to estimate a version of the CDM model of R&D, innovation, and productivity [Crépon–Duguet–Mairesse 1998. Research, innovation and productivity: An econometric analysis at the firm level. Economics of Innovation and New Technology 7, no. 2: 115–58] that has been modified to include ICT investment and R&D as the two main inputs into innovation and productivity. We find that R&D and ICT are both strongly associated with innovation and productivity, with R&D being more important for innovation, and ICT investment being more important for productivity. For the median firm, rates of return to both investments are so high that they suggest considerably underinvestment in both these activities. We explore the possible complementarity between R&D and ICT in innovation and production, but find none, although we do find complementarity between R&D and worker skill in innovation.     

Incorporating innovation subsidies in the CDM framework: empirical evidence from Belgium

ABSTRACT

This paper integrates innovation input and output effects of R&D subsidies into a modified Crépon–Duguet–Mairesse (CDM) model. Our results largely confirm insights of the input additionality literature, i.e. public subsidies complement private R&D investment. In addition, results point to positive output effects of both purely privately funded and subsidy-induced R&D. Furthermore, we do not find evidence of a premium or discount of subsidy-induced R&D in terms of its marginal contribution on new product sales when compared to purely privately financed R&D.     

Spillovers,product innovation and R&D cooperation: a theoretical model

ABSTRACT

We analyze the impact of post-innovation knowledge spillovers on firms’ decisions to invest and cooperate in R&D, forming a research joint venture (RJV). We study the case of two potential investors involved in a non-tournament stochastic competition for developing a new but imitable product. We propose a theoretical model where cooperation may emerge as a subgame perfect Nash equilibrium of a three-stage game. In the first stage, firms decide whether to cooperate; in the second, they decide whether to invest; and in the third, they compete. We show that firms cooperate in R&D when the spillovers are high enough and the fixed costs associated with R&D activities are low enough; however, our analysis suggests that forming an RJV may not always be socially optimal, and subsidizing R&D cooperation may not be efficient. We propose an optimal scheme of subsidies, which should be designed according to the intensity of the spillovers, the level of the R&D costs, and the probability of innovation success. Finally, we show that in the case of mergers the private incentive to invest is maximized, and firms may not need public subsidies to cooperate. When subsidies are costly, not hindering mergers may be the second-best solution.     

Dynamics of firm's network community associations and firm's innovation performance

ABSTRACT

R&D network structures have crucial impacts on firm's innovation performance. However, most previous studies have been based on the whole or ego network perspective, few studies have investigated the influence of community structure that a firm is engaged in on its innovation performance, and it is still unclear how a firm's relation to network community affect its innovation performance. This research aims to address this gap by focusing on the dynamics of firm's network community associations, empirically investigate the relationship between dynamics of firm's network community associations and its innovation performance. Based on the unbalanced panel data of smartphone R&D network during year 2004–2017, the results demonstrate that change in community member associations and movement across communities both have inverted-U-shaped effects on firm's innovation performance. Moreover, innovation openness depth has moderating effects on the relationships between dynamics of firm's network community associations and its innovation performance.     

Bioenergy innovation and energy policy

Using panel data on 13 OECD countries between 1979 and 2008 this paper examines the affect climate and energy policies have had on the rate of biotechnology innovations. The explanatory variables include a vector of important determinants of patenting activity for biotechnologies (e.g. specific and general research and development expenditures, energy consumption, energy prices and total number of registered patents). Fixed effects are employed to capture unobservable country-specific heterogeneity using a negative binomial model. The empirical results indicate that policies are important for stimulating innovations in biotechnologies. The development of feed-in-tariffs (FITs) and the implementation of tradable green certificates have had a positive and statistically significant impact on patent activity. The economic impact of green certificates is found to be larger than that of FITs. In addition, R&D activities have also had a positive and statistically significant effect on innovation.
