Process and product R&D by a multiproduct monopolist

It is shown that the claim in Lambertini that a multiproductmonopolist's incentive for process R&D declines with thenumber of products it offers is incorrect. This incentive isin fact an increasing function of the number of products inhis model. I further extend the model of Lambertini to showthat whether or not process R&D incentive and the numberof varieties are positively related depends on the degree ofscope economies in process R&D. Product innovation promotesprocess R&D if the degree of such scope economies is high(as in Lambertini), and discourages it if the degree of scopeeconomies is low.     

Sectoral Productivity Growth and R&D Spillovers in the Netherlands

This paper assesses empirically whether R&D spillovers are important and whether they originate from domestic or foreign activities. Data for eleven sectors are used to explain the impact on total factor productivity of R&D by the sector itself, by other Dutch sectors and by foreign sectors. We find that both domestic and foreign R&D are significant for the Dutch economy. The elasticity of total factor productivity with respect to R&D is approximately 37% for R&D by a sector, 15% for R&D by other Dutch sectors and 3% for R&D by foreign sectors. Our findings suggest moreover that more R&D speeds up the adoption of foreign technologies. Thus, even for a small open economy as the Netherlands, promoting investment in R&D is appropriate as it both stimulates adoption and generates spillovers.     

A note on the time inconsistency of strategic trade policy

In a simple three-stage model of an international Cournot duopoly, optimal strategic trade policy is shown to be time inconsistent. If the domestic government first announces a production subsidy, firms then irrevocably commit resources to R&D, and finally play their output game, there is an incentive for the government to revise its ex ante optimal policy once R&D decisions have been made. If private agents anticipate this revision and if the government does not have the power to commit itself to the ex ante optimal policy, a credibility constraint has to be imposed.     

Tax policy implications for a two‐engine growing economy

In an endogenous growth model with two engines of R&D and capital, we investigate the environment of “inclusive growth” for tax reallocations (tax increases or tax credits) to gain broader benefits in terms of promoting the overall GDP growth without an increase in income inequality. Our results show that a tax increase in the capital‐good sector can result in inclusive growth, boosting overall growth and reducing income inequality, provided that the status quo tax rate is not too high. Surprisingly, tax credits are not able to achieve such inclusive growth. While the GDP growth rises, a tax credit in the R&D sector not only increases income inequality but also decreases the aggregate employment, if the labor mobility cost between the final‐good and R&D/capital‐good sectors is relatively low. This provides a caution to policymakers given the fact that research tax credits have served as a common incentive to strengthen the R&D environment.     

Global warming and technical change: Multiple steady-states and policy options

We develop an economic growth model that incorporates anthropogenic climate change and a publicly funded research sector that creates new technologies and simultaneously expands the productivities of existing technologies. Greenhouse gas emissions are affected by R&D activities both negatively, through the increase of output from productivity growth, and positively as new technologies are less polluting. We find that there may exist two different steady-states of the economy, depending on the amount of research spending: one with less new technologies being developed and the other with more technologies. Thus, a lock-in effect can arise that, however, can be overcome by raising R&D spending sufficiently such that the steady-state becomes unique. We derive the combinations of fiscal policy instruments for which that can be achieved and we study the implications for the economy and with respect to emissions. In particular, the double dividend hypothesis may hold under some specific conditions.     

Innovation,learning, and exporting in China: Does R&D or a technology index matter?

This paper undertakes econometric analysis of innovation, learning, and exporting in automobiles and electronics firms in China using a large-scale 2003 dataset to identify the most appropriate innovation proxy. Drawing on recent literature on innovation and learning in developing countries, it tests two alternative proxies: (i) a technology index (TI) to capture a variety of minor activities involved in using imported technologies efficiently; and (ii) the research and development (R&D)-to-sales ratio, which represents formal technological efforts to create new products and processes, often at world frontiers. A higher TI increases the probability of exporting in both industries, while the R&D-to-sales ratio was not significant. Foreign ownership, technical manpower, and the characteristics of the general manager/chief executive officer also matter. The findings suggest that China's remarkable success in the export of automobiles and electronics since initiating an open-door foreign direct investment (FDI) policy in 1978 is linked to technology transfer from multinationals; systematic investments in and upgrading of minor technological activities (like search, engineering, quality management and design); and human capital. As China's per capita income rises over time, however, formal R&D activities are likely to become more important to sustain competitiveness and technological upgrading in automobiles and electronics.     

R&D and patenting activities of foreign firms in China: The case of Japan

This study investigates the research and development (R&D) and patenting activities of foreign firms in China. Utilizing a panel dataset of Japanese affiliates during the period 2001–2007, we first examine the determinants of R&D activity and find that local market-oriented firms place more emphasis on R&D, whereas process export-oriented firms are less likely to conduct R&D. Affiliates within a large business group that has more affiliates have a higher propensity to undertake R&D. Using only firms with positive R&D expenditures, we next estimate the patent production function. Results indicate that the patent elasticity of R&D for Japanese affiliates is high, suggesting that they are more productive on patent production than other firms. Moreover, local market-oriented firms do need more patents to protect their products, whereas scientific firms demonstrate a lower willingness to register patents in China.     

R & D decisions under alternative regulatory constraints

IV. Summary and Conclusions The purpose of this paper has been to extend the range of consequences implied by government regulation of privately owned firms. The analytical framework of Section II concentrated on deriving the implications of alternative degrees of regulation on the firm's research and development (R&D) decisions. The analysis implies that managers of stringently regulated firms have greater incentive to neglect such activities related to the search for and production of valuable market information which increases owners' wealth. Among other things, this implies that firms subject to more restrictive regulatory climates are more likely to commit fewer expenditures to R&D activities.Empirical evidence from the electric power industry was presented in Section III. The results indicate that the interfirm differences in R&D expenditures in this industry can be explained to a large extent by the variability of governmentally imposed regulatory constraints. After controlling for other determinants of R&D behavior, the evidence reveals that electric power firms subject to the most restrictive regulatory constraints do significantly (at the 5 percent level and better) less R&D than firms operating under the weakest regulatory constraints.This paper is based on the author's master's thesis, submitted to George Washington University in May 1976.

Do R&D tax incentives work? Firm-level evidence from China

Tax incentives have been used worldwide to encourage firm R&D, but there is little evidence on their effectiveness as a policy tool in developing countries. We use a panel dataset of Chinese listed companies covering 2007 to 2013 to assess the effects of tax incentives on firm R&D expenditures and analyze how institutional conditions shape these effects. Our results show that tax incentives motivate R&D expenditures for our sample firms. A 10% reduction in R&D user costs leads firms to increase R&D expenditures by 3.97% in the short run. We also find considerable effect heterogeneity: Tax incentives significantly stimulate R&D in private firms but have little influence on state-owned enterprises' R&D expenditures. Moreover, the effects of tax incentives are more pronounced for private firms without political connections. Hence, reducing political intervention complements tax incentives' capacity to foster firm R&D in developing countries.     

R&D Spillovers for Public R&D Productivity

ABSTRACT

This paper empirically investigates whether the productivity of a public (government-funded) R&D project improves when the aggregate R&D investment in the same technology field increases. Based on the unique project level data that cover almost entire public R&D projects in Korea, this paper shows that aggregate investment in other public R&D projects in the same technology field increases a public R&D project’s outputs both independent of its project expenditure (additive spillover effects) and interactive with its project expenditure (multiplicative spillover effects). The spillover effects from the aggregate private R&D investment in the same technology field also exist, but to a much lesser extent.     

Subsidizing R&D Cooperatives

A framework is developed with which the implementation of two commonly used R&D-stimulating policies can be evaluated: providing R&D subsidies and sustaining the formation of R&D cooperatives. Subsidized R&D cooperatives can also be analyzed. The analysis shows that providing R&D subsidies is more effective in raising private R&D investments than sustaining R&D cooperatives. Moreover, optimally subsidizing cooperative R&D or noncooperative R&D leads to the same level of R&D activity. Sustaining R&D cooperatives thus appears to be a redundant industrial policy, all else equal.     

Regional Skill Structure and the Diffusion of Technology

This paper examines the relationship between the skill structure of states manufacturing sectors and technological change. Various measures of technological change are utilized including private and public R&D stocks, high-tech capital, recent capital, and the spatial spillover effects attributed to R&D stocks. We analyze the impact of changes in technology on spatial wage-bill shares, utilizing panel data for the 48 contiguous states over three sequential five-year periods. Overall, the results show a positive connection between skill upgrading and technological change. In other words, we find that states that adopt new technologies have more skilled workforces. Of particular interest, we find that publicly funded R&D stocks from neighboring states play a significant role in skill upgrading. The general implication of this finding is that geographic proximity is key to diffusing government-funded technology that enhances state economic performance. Our results strengthen the case for regional cooperation among states in developing policies to attract both private and public R&D capital.     

R&D Tournaments with Spillovers

This paper studies the influence of uncertainty and spillovers on a contestant's R&D spending. The relationship between market structure and R&D spending is shown to be sensitive to the form of uncertainty that characterizes the R&D process. When reward to the winner is endogenously determined by R&D spending, a contestant's R&D spending may increase with the degree of spillovers.     

The effects of product liability costs on R&D with asymmetric information

This paper examines the effects of product liability costs on R&D with asymmetric information. When the product is defective, both the consumer and producer share the resulting losses. This paper explores the impacts of liability costs on the firm’s R&D decisions in three information structures: full information; hidden information; and hidden information and hidden action. It is found that the effects differ across information structures. This paper also compares the equilibrium amounts of R&D and social welfare levels across three cases. Equilibrium R&D is smaller than the socially optimal level for each information structure.     

New Pills for Poor People? Empirical Evidence after GATT

The protection of pharmaceutical innovations is being dramatically extended as much of the developing world introduces patent protection for new drug products. This change in intellectual property rights may lead to more research on drugs to address developing country needs. We use new survey data from India, the results of interviews, and measures of research and development (R&D) constructed from a variety of statistical sources to determine trends in the allocation of research to products specific to developing country markets. There is some, although limited, evidence of an increase in the mid- to late 1980s which appears to have leveled off in the 1990s.The picture presented provides a “baseline” against which future patterns in research activity can be compared.     

A Duality Between Cost-Reducing R&D versus Quality-Improving R&D and Welfare Analysis in a Hotelling Model

Two versions of research and development (R&D) activities in a Hotelling model with endogenous spillover effect, one with cost-reducing R&D and the other with quality-improving R&D, are analyzed in this paper. The result points out that two such kinds of R&D activities will share identical strategic properties, and that we shall be able to derive the equilibrium strategies of a quality-improving R&D model from those of a cost-reducing R&D model, and vice versa. It is found that the special market demand in a Hotelling model in fact plays a crucial role as well. This paper also provides a welfare analysis, the results of which show that government intervention via taxing the locations and subsidizing R&D efforts can remedy the market failure resulting from excess differentiation on locations and under-investment on R&D expenditures in non-cooperative equilibrium.     

Pharmaceutical Patents: Incentives for Research and Development or Marketing?

We analyze how a patent‐holding pharmaceutical firm may strategically use advertising of existing drugs to affect research and development (R&D) investments in new (differentiated) drugs, and thereby affect the probability distribution of future market structures in the industry. Within a fairly general model framework, we derive exact conditions for advertising and R&D being substitute strategies for the incumbent firm and show that it may overinvest in advertising to reduce the incentive for an entrant to invest in R&D, thereby reducing the probability of a new product on the market. In a more specific setting of informative advertising, we show that such overinvestment incentives are always present and that more generous patent protection implies that a larger share of the patent rent is spent on marketing, relative to R&D.     

Establishing science parks everywhere? Misallocation in R&D and its determinants of science parks in China

The establishment of science parks is a vital strategy to develop high-tech industries and facilitate innovations in China. The success of a science park depends heavily on its supportive environment, suggesting that it is hard to replicate everywhere, while China has established many science parks across regions in the past decade. This study evaluates the degree of misallocation in research and development (R&D) and its determinants across science parks in China. Based on an unbalanced panel data of 145 science parks for the period 2007–2014, we find that the overall R&D efficiency has decreased sharply since 2011 when China began to initiate many new science parks. The newly constructed science parks exhibit a lower R&D efficiency than their incumbent parks, suggesting a considerable misallocation in R&D resource caused by expanding science parks everywhere. We further investigate the determinants of R&D misallocation and find that park characteristics and environmental characteristics matter. Parks which are larger, older, and having a higher human quality experience a lower R&D misallocation. Parks with closer R&D collaboration with universities or research institutes, particularly with universities, exhibit a lower R&D misallocation.     

Product Reliability,R&D,and Manufacturing Cost Shocks

Suppose a firm’s research and development (R&D) improves product reliability which in turn decreases the cost of product failure for both the firm and its customers. The primary research question of the paper is how a firm with market power optimally adjusts its R&D if it experiences a manufacturing cost shock. Our model suggests that a manufacturing cost shock prompts the firm to do less R&D in the cases where the replacement cost is low or the marginal manufacturing cost is high. Conversely, if the replacement cost is high and the marginal manufacturing cost is low, then the firm increases R&D, mitigating some of the increase in the manufacturing cost. The paper also compares the outcomes for reliability, profits, consumer surplus, and social surplus for the optimal R&D case as compared to the case of doing no R&D, paying particular attention to how exogenous changes in the marginal manufacturing cost affect this comparison.     

Local land supply and fiscal incentives for R&D: Evidence from a quasi-natural experiment in China

Whereas numerous studies have evaluated the effects of public research and development (R&D) support programs and R&D tax incentives on private R&D, little is known about local governments' fiscal incentives for R&D. In this study, we build a conceptual framework to clarify the critical role of local land supply in relation to fiscal expenditure on R&D. We treat the establishment of China's nine Land Supervision Bureaus in 2006 as a quasi-natural experiment, and run a difference-in-differences regression to identify causality. The results show that local governments allocate more fiscal expenditure to R&D in response to land-use supervision, which monitors illegal land granting behaviors, and this effect is stronger in cities where leaders have higher political career incentives and cities with greater fiscal decentralization. Moreover, we find that land-use supervision increases the probability and scale of firms' access to government subsidies for R&D; thus, enhancing regional innovation capacity. Our findings document that China's land resource is a curse for its innovation-driven growth as it impedes local governments' fiscal incentives for R&D.
