Environmental regulations and innovation activity in UK manufacturing industries

We examine the relationship between environmental regulations and innovation, using data from UK manufacturing industry during 2000-2006. We estimate a dynamic model of innovation behaviour, and explicitly account for the likely endogeneity of our measure of the stringency of environmental regulations (pollution abatement costs). Our results indicate that while on the one hand environmental R&D and investment in environmental capital are stimulated by greater pollution abatement pressures, on the other hand there is not a positive impact of environmental regulation on total R&D or total capital accumulation. We find some evidence that this is because more stringent environmental regulations directly lower the optimal expenditure on non-environmental innovations. In addition, we find that environmental R&D may crowd out non-environmental R&D, although there is no evidence that environmental capital crowds out non-environmental capital.     

Testing a model of UK growth: A role for R&D subsidies

R&D is a main driver of growth, whether by generating new ideas for production or increasing technological transfer. However, R&D itself is risky and faces numerous barriers which may reduce its marginal return. Direct R&D subsides are intended to counteract such barriers, but whether they lead empirically to increased economic growth is unclear. In our structural model of the UK, subsidies offset the frictional costs associated with R&D, incentivising innovation and so stimulating productivity growth. We estimate and test this structural model by indirect inference, a method not previously used in work on R&D. We find that even temporary cuts to R&D funding have long-lasting impacts on UK economic growth. The power of the test allows us to calculate tight accuracy bounds for our results and for policy reform impacts calculated using the model. These findings are of high relevance to the ongoing debate around the future UK innovation environment.     

The struggle to survive in the R&D sector: Implications for innovation and growth

By allowing for investment activities by research and development (R&D) firms to prevent product obsolescence, we show that if legal patent protection is too strong, a higher R&D subsidy rate delivers insufficient investments for survival in the R&D sector, depressing innovation and growth in the long run.     

Research and development and trade policies for product innovation in the presence of foreign competition

This paper examines two policy instruments — a matching grant and import tariffs — for encouraging research and development (R&D) in product innovation by a domestic firm when it faces foreign competition. We do so by developing a theoretical model of product innovation where R&D effort is endogenous and its outcome uncertain. We examine the effects of a reduction in import tariffs on private expenditure on R&D, on public support for such R&D, and on total R&D expenditure. We find that in response to a reduction in import tariffs, the domestic firm always reduces its private R&D investments, but the total level of R&D expenditure (i.e., including public support) might go up depending on the level of tariffs. In particular, we find that it will go up if the initial level of tariff is higher than a critical level. When tariff is endogenous, we find that the socially optimal level of tariffs is positive. One finding that is of particular interest is that supporting private attempts to product innovate in the form of a matching grant program leads to a socially optimal level of product R&D.     

Spillovers and the competitive pressure for long-run innovation

This paper discusses the impact of oligopolistic product markets for innovation and growth, highlighting a novel, fundamental role of spillovers. We develop a model of endogenous growth with non-tournament R&D, where spillovers raise the relative R&D efficiency of laggards. A key feature is that the rate of innovation and the market configuration (i.e. the distribution of market shares) are jointly determined. Our results emphasize the role of spillovers in sustaining the competitive pressure that is fundamental for long-run innovation and economic growth.     

Cooperation or competition in R&D when innovation and absorption are costly

This article analyzes cost-reducing R&D investments by firms that behave non-cooperatively or cooperatively. Firms face a trade-off between allocating their R&D investments to innovate or to imitate (absorb). We find that the non-cooperative behavior not only induces more imitation (absorption) but also, for the most part, more innovation investments. Only the cooperative behavior, however, ensures that R&D investments are allocated efficiently to innovation and to imitation (absorption) in the sense that any given amount of industry-wide cost reduction is obtained for the minimum overall R&D costs.     

Infra-industry spillovers and R&D cooperation: Theory and evidence

We analyse both the theoretical and the empirical side of the issue of R&D spillovers. Each firm's R&D costs are increasing in the amount of information transmitted to other firms, and we account for the possibility that firms control spillovers. We consider both Cournot-Nash and Cournot-Stackelberg behavior. The empirical analysis suggests that (i) firms' control on spillovers is relatively low; (ii) the cost-saving effect associated to joint ventures or R&D cartels is confirmed for industries where firms rely mainly upon own R&D as a source of innovation; (iii) R&D cooperation may increase information sharing, thereby enhancing spillovers.     

How does firm diversification impact innovation?

This study sheds light on the relationship between business diversification and innovation. A diversification strategy is both a driver of sunk costs and strategic slack. Strategic slack is a valuable reserve of knowledge, usable to foster innovation. Using linear models, we explore the interplay between research and development (R&D) and organisational slack in large and diversified companies listed on the Euronext 100 Index. We consider the diversification pattern over time, and its interactions with the following three categories: sunk costs, slack resources, and R&D. The results show an antithetic effect of diversification and slack on R&D expenditures. In contrast to unabsorbed and potential slack, diversification and sunk costs hinder innovation. However, diversification is a huge source of strategic slack and, thus, has a positive effect on innovation, indirectly.     

The role of diminishing returns in neo-Schumpeterian growth theory

Summary. This paper generalizes Segerstrom [5], a dynamic general equilibrium model of endogenous growth through quality improvements in which innovation and imitation are modeled as the outcomes of research and development (R&D) races. Specific factors introduced into the technologies of both R&D activities achieve diminishing returns to scale in R&D. The comparative-static results of subsidies to R&D activities depend on the degree of diminishing returns to scale in R&D. When there is (is not) a sufficient degree of diminishing returns to R&D, a subsidy to innovative activity increases (decreases) innovative activity.

R&D policy with layers of economic integration

This paper examines whether the optimal unilateral R&D policy for an open economy is a subsidy or a tax. It constructs a general equilibrium model with three successive layers of international integration: (a) trade in goods, (b) trade in technologies with international R&D spillovers and (c) internationally-coordinated R&D policy. Trade in technologies introduces the possibility that an R&D subsidy will have such strong, negative terms-of-trade effects that it harms domestic welfare. Numerical simulations of the OECD show this is a possibility for the US and Japan. With international R&D spillovers a domestic R&D subsidy may reduce domestic innovation.     

Knowledge appropriability, firm size, and growth

Empirical evidence shows that the number of patents per R&D dollar declines with firm size. In this paper, we propose a Schumpeterian growth model that accounts for this evidence. We analyze an economy with firms that engage in cost-reducing innovation resulting from the accumulation of both codified and tacit knowledge: the former occurs through the purchase of patents, while the latter is the result of R&D conducted in-house by firms. We study the relation between knowledge appropriability and market structure, and we show that a shift from patents to in-house research occurs as firm size gets larger. Since innovation statistics concentrate mainly on patents, this process of research reallocation results into an under-estimation of innovative activity and is responsible for the declining ratio of patents to R&D expenditure. Survey data on UK-based firms provide support to our results.     

Technological convergence, R&D, trade and productivity growth

This paper analyses productivity growth in a panel of 14 United Kingdom manufacturing industries since 1970. Innovation and technology transfer provide two potential sources of productivity growth for a country behind the technological frontier. We examine the roles played by research and development (R&D), international trade, and human capital in stimulating each source of productivity growth. Technology transfer is statistically significant and quantitatively important. While R&D raises rates of innovation, international trade enhances the speed of technology transfer. Human capital primarily affects output through private rates of return (captured in our index of labour quality) rather than measured TFP.     

Product market competition,R&D composition and growth

We revisit the relation between product market competition and leading-edge growth in a model where horizontal and vertical innovations simultaneously occur. We show that competition exerts an important effect on the composition of aggregate R&D (vertical versus horizontal). In fact, when product market competition gets more intense, a larger fraction of R&D is engaged in improving the quality of products; this occurs at the expense of a lower rate of horizontal innovation. This effect, which is absent in the basic endogenous growth model with only vertical innovations, may overturn the inverse relation between product market competition and leading-edge growth found in prior theoretical models.     

Product differentiation, process R&D, and the nature of market competition

We investigate the relationship between process and product R&D and compare the incentives for both types of R&D under different modes of market competition (Bertrand versus Cournot). It is shown that: (i) process R&D investments increase with the degree of product differentiation and firms invest more in product R&D when they can do process R&D than when they cannot; (ii) Bertrand firms have a stronger incentive for product R&D whereas Cournot firms invest more in process R&D; and (iii) cooperation in product R&D promotes both types of R&D relative to competition whereas cooperation in both types of R&D discourages R&D relative to cooperation in just product R&D.     

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.     

Costly investment, complementarities and the skill premium

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities between intermediate goods. We only find a positive relationship between the relative labour endowment and both the skill premium and economic growth within determined intervals of relative labour endowment values, which vary with the absolute productive advantage of high over low-skilled labour. The model thus accommodates theoretically mixed empirical results on the relative labour endowment-skill premium relationship. We further find that the impact on both the relative labour endowment and the skill premium of a rise in investment costs or in the complementarities degree depends on: (i) the absolute productivity advantage of high over low-skilled labour; and (ii) the relative labour endowment.     

Patents and quality growth in OLG economy

This paper shows how heterogeneity in patent ownership across generations and lifecycle saving considerations qualitatively change the conventional implications of patent policy for quality growth. We study a close Overlapping Generations economy that grows through sequential quality improvements (“quality-ladder”), to show that for plausible values of the Inter-temporal Elasticity of Substitution (a) shorter patent length enhances growth (b) under exogenous innovation size loosening patent breadth protection spurs R&D investment and quality growth and (c) the effect of loosening lagging breadth protection on R&D investment and quality growth under endogenous innovation size depends on patents length. Our findings explore a new channel through which strong patents may hinder innovation and emphasize the importance of coordination in patent-policy across the different dimensions of the patents system.     

Property rights protection and corporate R&D: Evidence from China

Following the recent literature on institutions and economic growth, we examine the effects of property rights protection on corporate R&D. Using a unique 2003 World Bank survey of over 2400 firms in 18 Chinese cities, we obtain the following findings: (1) property rights protection is positively and significantly related to corporate R&D activity (for both process and product R&D); (2) government services and helping hand are conducive to corporate R&D, while informal payments to government officials are not; and (3) government ownership of firms and direct appointment of CEOs are negatively associated with corporate R&D activities. We also find that corporate R&D is positively related to firm size, and access to finance, but negatively related to product market competition and firm age.     

Innovation And Job Creation In A Smallopen Economy-Evidence From Norwegian Manufacturing Plants 1982–92

It is often claimed that the opportunities to create new manufacturing jobs in open, high-cost economies such as Norway, are concentrated in activities which are technologically advanced and knowledge intensive. This paper examines the relationship between job creation and innovation, as measured by R&D investments, in Norwegian manufacturing. We compare job creation in plants belonging to R&D firms to job creation in plants belonging to firms without R&D. We also compare job creation in plants belonging to high and low tech industries. Our data set covers more than 80 percent of manufacturing employment in Norway over the period 1982–92. The paper challenges the optimistic view about job creation in R&D intensive firms and high-tech industries. Some main findings are: (i) Net job creation is not higher in high-tech industries. (ii) There is no clear-cut positive relationship between net job creation and the R&D-intensity of the firm. (iii) There is less net job creation and less job-security in R&D-intensitefirms in the late 1980s and early 1990s.     

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.
