Process and product R&D by a multiproduct monopolist: a reply to Lin

With reference to Lambertini (2003), Lin correctly points outthat, if R&D efforts for process innovation are endogenous,then process and product R&D are strategic complements.Then, he also proves that the opposite holds when spilloversare nil. Objecting to Lin's second claim, I show that monopolyprofits are everywhere increasing in the extent of informationsharing within the firm. Consequently, the full internalisationof spillovers restores the complementarity between process R&Dand product proliferation.     

Inequality in healthcare R&D outcomes: a model of process disruption

ABSTRACT

The developing world has substantively different healthcare research and development (R&D) needs than the developed world. In this paper it is argued that healthcare inequality is primarily an outcome of the incentives of an innovation system that privileges wealthy markets. Given the difficulties inherent in challenging these incentive structures, it might be the R&D process itself (rather than its incentive structures) that, if disrupted, may ultimately improve access to R&D outcomes for poor populations. The objective of this paper is to spur novel thinking about the problem of healthcare inequality by developing a provocative conceptual model of healthcare R&D process disruption, based on the application of novel technologies to the research process itself, to radically lower the costs of R&D. The model developed here suggests that healthcare inequality might ultimately be mitigated by substantial reductions in time and cost in the biomedical R&D process made possible by novel technologies.     

R&D Subsidies and Foreign Direct Investment

We devise a model in which domestic firms do applied R&D, which can be subsidized by the government, and foreign firms with superior technology can enter in the domestic market. Foreign Direct Investment can act as a substitute of subsidies to improve domestic R&D, the share of domestic leading firms and consumption. Relatively closed economies may benefit from R&D subsidization while relatively open economies may not. For relatively low growth of the technological frontier, it is optimal to subsidize R&D and close the economy to foreign investment but the opposite happens for relatively high growth. Numerical simulations show the economy dynamics after policy experiments.     

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.     

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.     

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 Innovation Threshold

Summary This paper discusses a model for analysing the sales of new products. This model accounts for the fact that, even among those companies with permanent R&D activities, a fraction of the firms did not have sales of innovative products over a two-year observation period. We propose a model in which the fixed costs of introduction are a major concern in the decision-making process. We apply a censored regression model, extended by a firm-specific threshold. We use a structural model to estimate the fixed costs of introducing new products to the market, and explain subsequent sales of innovative products. We examine an indicator of innovative output, i.e. the sales of products ‘new to the firm’. We estimate fixed cost thresholds by using data from the Dutch section of the Community Innovation Survey (CIS) of 1998. R&D intensity, competition, and market structure all have a positive impact on the sales of new products. The most important factors that reduce the fixed cost threshold of introduction are product-related R&D investments, R&D subsidies, and knowledge spillovers. We would like to thank Geert Ridder, Alfred Kleinknecht and two anonymous reviewers for their valuable comments and discussion.     

R&D spillovers and the case for industrial policy in an open economy

In this paper we consider the case for subsidies towards firmswhich generate R&D spillovers in open economies. We showthat in the presence of strategic behaviour by firms many expectedresults are overturned. Local R&D spillovers to other domesticfirms may justify an R&D tax rather than a subsidy; R&Dcooperation by local firms over-internalises the externalityand also justifies an R&D tax; and international spilloverswhich benefit foreign firms may justify a subsidy, even thoughthe government cares only about the profits of home firms.     

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.     

Does an R&D tax credit affect R&D expenditure? The Japanese R&D tax credit reform in 2003

To what extent does a tax credit affect firms’ R&D activity? What are the mechanisms? This paper examines the effect of R&D tax credits on firms’ R&D expenditure by exploiting the variation across firms in the changes in the eligible tax credit rate between 2000 and 2003. Estimating the first-difference equation of the linear R&D model by panel GMM, we find the estimated coefficient of an interaction term between the eligible tax credit rate and the debt-to-asset ratio is positive and significant, indicating that the effect of tax credit is significantly larger for firms with relatively large outstanding debts. Conducting counterfactual experiments, we found that the aggregate R&D expenditure in 2003 would have been lower by 3.0–3.4 percent if there had been no tax credit reform in 2003, where 0.3–0.6 percent is attributable to the effect of financial constraint, and that the aggregate R&D expenditure would have been larger by 3.1–3.9 percent if there had been no cap on the amount of tax credits, where 0.3–0.8 percent is attributable to relaxing the financial constraint of firms with outstanding debts.     

研发效率、技术溢出与政府的创新补贴

 在一个三阶段博弈模型的基础上,本文研究了存在技术溢出情况下政府的创新激励政策与企业的研发策略。结果表明,无论是实行竞争型创新补贴政策还是合作型创新补贴政策,政府都应该优先补贴那些低成本、高效率的创新行为。贸易自由化提高了国家的创新补贴水平,但是技术溢出本身对创新补贴的影响却具有不确定性。文章的结果同时显示,贸易便利化的实施与高技术溢出提高了消费者剩余与国民福利水平。贸易壁垒虽然强化了企业对本国市场的垄断,但是,在考虑了政府的创新补贴政策后,具有创新激励的企业实际上更倾向于自由贸易结果,因此,相对于严格的专利保护制度,创新补贴政策可能更容易促进国民福利水平的提高。     

A Cross‐national Comparison of R&D Expenditure Decisions: Tax Incentives and Financial Constraints*

We provide evidence on the impact of tax incentives and financial constraints on corporate R&D expenditure decisions. We contribute to extant research by comparing R&D expenditures in the United States and Canada, thereby exploiting the differences in the two countries' R&D tax credit mechanisms and generally accepted accounting principles. The two tax incentive mechanism designs are consistent with differing views of the degree of financial constraints faced by firms in these economies. Our sample also allows us to explore the effects of capitalizing R&D on Canadian firms. Employing a matched design, we document relations between tax credit incentives and R&D spending consistent with both Canadian and U.S. public companies responding as though they are not financially constrained. We estimate that the Canadian credit system induces, on average, $1.30 of additional R&D spending per dollar of taxes forgone while the U.S. system induces, on average, $2.96 of additional spending. We also find that firms that capitalize R&D costs in Canada spend, on average, 18 percent more on R&D. Collectively, this evidence is important to the ongoing debates in both countries concerning the appropriate design of incentives for R&D and is consistent with the assumptions found in the U.S. tax credit system, but not those found in the Canadian system.     

研发国际化与企业创新绩效——吸收能力和地理多样性的调节作用

新兴经济体企业的国际化行为已经成为国际商务领域的研究热点之一,但如中国这样的新兴经济体的跨国企业是否能够通过研发国际化行为提升母公司的创新绩效,现有文献对该问题尚缺乏足够的研究。文章基于2011-2017年间沪深两市310家信息技术业上市跨国企业的年度观察数据,采用泊松面板固定效应模型考察了企业研发国际化与母公司创新绩效之间的关系,并首次从逆向知识转移的视角,探讨了吸收能力和地理多样性对研发国际化和创新绩效两者关系的调节作用。实证结果表明：中国企业的研发国际化显著促进母公司创新绩效的提升;以研发投入强度衡量的企业吸收能力显著正向调节研发国际化和创新绩效之间的关系,而以布劳异质性指数测量的地理多样性则显著负向调节研发国际化和创新绩效的关系。研究结果对中国企业国际化行为具有重要启示。该研究发现意味着中国企业在国际化过程中应该加大海外研发投资力度以提升母公司创新绩效,且为更好地实现外部知识的逆向转移,应同时提高企业总体研发投入强度。但作为新兴经济体企业,不宜在地理分布上实行快速扩张,否则较高的沟通和协调成本将弱化逆向知识转移的程度,而不利于母公司创新绩效的提升。     

Advertising, in-house R&D, and growth

This paper develops a quality-ladder model of endogenous growthto study the interplay between in-house R&D and combativeadvertising expenditure, and its implications for economic growth,firm size, and welfare. The analysis shows that, somewhat surprisingly,higher incentives to engage in advertising, although combative,unambiguously foster innovation activity of firms. This, possibly,leads to faster growth and even higher welfare. These resultsrest on two features of the model which are well-supported byempirical evidence. First, if firms incur higher sunk costsfor marketing, concentration and firm size rise. Second, firmsize and R&D expenditure are positively related as largerfirms are able to spread R&D costs over higher sales. Theanalysis also suggests that R&D subsidies are conduciveto R&D and growth without inducing firms to raise advertisingoutlays.     

Strategic R&D policy in a quality-differentiated industry with three exporting countries

We examine strategic research and development (R&D) policy for quality-differentiated products in a third-market trade model. We extend the previous work by adding a third exporting country, so that the market structure is international triopoly. We show that the presence of the third exporting country affects strategic R&D policies. With three exporting countries, the lowest-quality exporting country gains from taxing domestic R&D and the middle-quality exporting country gains from subsidizing domestic R&D under both Bertrand and Cournot competition. As in the duopoly case, however, the optimal unilateral policy for the highest-quality exporting country depends on the mode of competition. Various cases of policy coordination by exporting countries are also examined.     

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.     

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.     

R&D,unemployment, and labor market policies

This paper studies the effects of labor market policies on R&D activities and unemployment. I develop a search and matching model in which firms’ R&D decisions are endogenously determined. The model demonstrates that more intensive labor market policies that protect workers reduce the levels of R&D activities. This study offers a theoretical framework to understand the relationship between R&D activities, labor market policies, and unemployment which is discussed in empirical studies.     

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.

Efficiency change and productivity growth in agriculture: A comparative analysis for selected East Asian economies

This study focuses on identifying the sources of agricultural growth for eight East Asian economies – with special emphasis on factors that can better explain different components of growth. The Malmquist productivity growth index and its two components are calculated and regressed on variables including the human capital endowment, domestic R&D, international spillovers, and country-specific farming characteristics to characterize the differential patterns of growth. Our empirical evidence suggests that domestic R&D and its interaction with human capital constitute the major determinant of individual economy's progress in agricultural technology, whereas the human capital endowment is crucial for the catching up effect. Furthermore, for foreign knowledge to contribute to productivity growth either through innovation or through catching up, the host economy has to develop a sufficient learning capacity from education. Countries that do not attempt to develop the learning capability to assimilate and exploit the freely available knowledge may not benefit from international spillovers of agricultural R&D.
