The effectiveness of R&D subsidies

In this paper, the effectiveness of R&D subsidies is analyzed in an oligopolistic model that we apply to the cases of international R&D competition and cooperation. We find that the existence of asymmetric information among firms on whether a rival (or partner) is being subsidized or not may play a key role in explaining whether subsidies are effective or not in increasing R&D investments. In particular, it is shown that if the existence of the subsidy is made public (e.g. because strict information release regulation about R&D subsidies is enforced) and depending on the strategic relationship between the firms’ R&D efforts, an R&D subsidy could even hurt the subsidized firm.     

Learning from successes and failures in pharmaceutical R&D

In this paper, we build a cumulative innovation model to understand the role of both success and failure in the learning dynamics that characterize pharmaceutical R&D. We test the prediction of our model by means of a unique dataset that combines patent information with R&D projects, thus distinguishing patents related to successfully marketed products from those covering candidate drugs that failed in clinical trials. Results confirm model predictions showing that patents associated with successfully completed projects receive more citations than those associated with failed projects. However, we also show that failed projects can be in turn cited more often than patents lacking clinical or preclinical information. We further explore the ‘black box’ of innovation, providing evidence that both successes and failures contribute to R&D investment decisions and knowledge dynamics in science-driven sectors.     

The Size of Firms and R&D Investment

We construct an industry-equilibrium model in which it is costly for consumers who have previously purchased from one firm to switch to competitors. This gives firms a certain degree of market power over their established customers. The equilibria we identify under these conditions have the following properties: (1) there is a nontrivial size distribution of firms, although firms are intrinsically identical, (2) larger firms make higher profits, (3) larger firms spend more on R&D, (4) larger firms charge (on average) lower prices, and (5) profits are positively correlated over time. These properties match empirical regularities concerning the manufacturing and retail sectors in the U.S. economy.     

R&D and productivity: Internal vs. external R&D - evidence from west german manufacturing industries

The paper explores the productivity effects of investment in external (contract) vs. internal (in-house) R&D in a sample of West-German Manufacturing Industries. The results provide strong evidence of a positive relationship between productivity and the share of external R&D in total R&D. This result is robust to alternative econometric specifications. Thus, findings suggest that the decision between internal and external R&D does matter. Moreover, results imply a nonlinear relationship between productivity and the share of external R&D for higher-technology industries, hinting at decreasing productivity effects of an increasing share of external in total R&D.     

Assessing the influence of differentiation strategy and R&D subsidies on R&D cooperation

This paper explores the R&D cooperation determinants of the innovative companies belonging to the Spanish manufacturing sector. Our findings suggest that the variable R&D subsidy is endogenous, significant, and has a strong positive influence on R&D cooperation. This is a clear indication that the achievement of public aid is often conditioned by the obligation for companies to cooperate in R&D. We have also found that the differentiation strategy variable is significant and has a negative influence on R&D cooperation. Companies positioned in a differentiation strategy probably own and use some different knowledge from other companies. Consequently, they will not have much interest in taking advantage of the spillovers generated by other companies. It is therefore logical that they are reluctant to establish cooperation agreements on R&D. Therefore, companies positioned in the differentiation strategy need public policies to support R&D that are not conditioned to the establishment of cooperation agreements.     

The spatial component of R&D networks

We study the role of geography in R&D networks by means of a quantitative, micro-geographic approach. Using a large database that covers international R&D collaborations from 1984 to 2009, we localize each actor precisely in space through its latitude and longitude. This allows us to analyze the R&D network at all geographic scales simultaneously. Our empirical results show that despite the high importance of the city level, transnational R&D collaborations at large distances are much more frequent than expected from similar networks. This provides evidence for the ambiguity of distance in economic collaboration which is also suggested by the existing literature. In addition we test whether the hypothesis of local buzz and global pipelines applies to the observed R&D network by calculating well-defined metrics from network theory.     

The Determinants of Industrial R&D in Australia*

This paper offers some evidence on the determinants of RAD spending in Australian manufacturing. Two-stage regressions are employed. Large size has a negative effect on RAD after adjustment for simultaneous equations bias. There is some indication that foreign ownership has a positive effect on RAD in higher technology industries. Tests to examine the role of government subsidy produced only insignificant coefficients.     

The R&D system for industrial development in Taiwan

The research and development (R&D) system for industrial development in Taiwan is made up of three parts: industrial firms, government-supported institutes (GSIs), and academic institutes and universities. The Taiwanese experience showed that the effective interaction of the GSIs and the industrial firms has successfully supported the development of its industry. The Industrial Technology Research Institute (ITRI) played the key role in industrial development during recent decades. This study provides a comprehensive analysis of ITRI and the way in which it fulfills its role through an examination of its major tasks. The implications for developing countries are also discussed.     

A dual economy model of endogenous growth with R&D and market structure

This paper develops a dual economy endogenous growth model to consider the effects of market structure and innovation on the rate of growth of an economy. There is an innovative goods sector where firms consistently invest in research and development to produce new products within a framework of monopolistic competition. Firms in the traditional goods sector produce a homogenous good, compete in a form of oligopoly (quantity competition), and seek to reduce their production costs. It is shown that growth is increasing in the market power that firms in the innovative goods sector obtain but decreasing in the equilibrium number of firms in the traditional goods sector.     

On the effect of R&D in returns to experience

Using a recent macroeconomic database, we empirically estimate an ‘erosion effect’: we show that Total Factor Productivity (TFP) growth decreases returns to experience. The ‘erosion effect’ is typically stronger within the rich and the most experienced countries in the world. This article complements the scarce microeconomic literature on the issue and the theoretical macroeconomic literature recently coming to the conclusion that this effect has important implications for the interaction between human capital accumulation and TFP.     

The Internet,R&D expenditure and economic growth

We examine the effect of the Internet on the relationship between R&D expenditure and economic growth. Data for 105 countries over the period 1994–2014 are used for panel data analysis. The effect of R&D expenditure on economic growth proves to be affected positively by the Internet and the effect of the Internet on the economic growth is positively strengthened by an increase in R&D expenditure.     

Institutions and the R&D of GM-crops

This paper analyzes how different institutional structures shape the research and development (R&D) of genetically modified crops (GM-crops). Whether this R&D is conducted within companies, cooperatives or public research organizations (both publicly and privately funded R&D) is expected to influence the type of crops and traits that are developed and therefore the effects on society and ecosystems that potentially could follow from the use of GM-crops. This issue is analyzed empirically by statistical analysis of 1323 notifications for field trials with GM-crops that have been submitted under two EU Directives in seven European countries. The results show that the type of R&D organization influences the traits and crops that are developed. Companies are more likely to submit notifications that concern GM-crops that secure the potential for profit than are other types of R&D organizations, while R&D organizations that are purely publicly funded are more likely to submit notifications that only concern biosafety research than are cooperatives and companies. Consideration of the environment, food safety and food security might justify institutional reforms of R&D of GM-crops. This might include increased public funding combined with changes in intellectual property rights.     

Multistage Contracting with Applications to R&D and Insurance Policies

An agent undertakes a nonobservable first‐stage effort. The principal observes whether the effort results in a successful project or not. If the project succeeds, only the firm observes its interim quality, and can further improve it with a nonobservable second‐stage effort. If the agent accepts penalties when the first‐stage fails, moral hazard and asymmetric information do not prevent the principal from implementing her first‐best outcome. However, if the agent is bounded by the maximum loss he can bear when the first‐stage fails (limited liability), the principal induces the agent to exert a first‐stage effort below the first‐best level and a second‐stage effort above the first‐best level when the interim quality of his project is low. This distortion in efforts implies that the ex post rent left to the agent with a project of high interim quality is above the first‐best level. This provides a rationale for the optimality of expanding the use of the “carrot” (second‐stage rent) when the use of the “stick” (first‐stage penalty) is restricted. Implications of the theory for R&D, bank, job, and insurance contracts are discussed.     

Relocation and investment in R&D by firms

The literature on foreign direct investment has analyzed corporate location decisions when firms invest in R&D to reduce production costs. Such firms may set up new plants in other developed countries while maintaining their domestic plants. In contrast, we here consider firms that close down their domestic operations and relocate to countries where wage costs are lower. Thus, we assume that firms may reduce their production costs by investing in R&D and likewise by moving their plants abroad. We show that these two mechanisms are complementary. When a firm relocates it invests more in R&D than when it does not change its location and, therefore, its production cost is lower in the first case. As a result, investment in R&D encourages firms to relocate.     

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.     

Profit-maximizing R&D in response to a random carbon tax

This paper determines a firm’s profit-maximizing R&D response to an uncertain carbon tax, for two different R&D programs: cost reduction of low carbon energy technologies and emissions reductions of currently economic technologies. We find that optimal R&D does not increase monotonically in a carbon tax. R&D into alternative technologies increases only if the firm is flexible enough; R&D into conventional technologies first increases then decreases in a carbon tax. Firms that are very flexible may increase R&D into alternative technologies when the uncertainty surrounding a carbon tax is increased; otherwise firms will generally decrease R&D investment in uncertainty.     

R&D and Productivity in German Manufacturing Firms

This papcr uses a new firm panel data set to explore the relationship between R&D and productivity in German manufacturing firms for the period from 1979 to 1989. The results confirm the view that K&D is an important determinant of productivity growth. In the cross-section, the elasticity of sales with respect to R&D capital is on the order of 14 per cent. Using fixed-effects estimators yields R&D elasticities of about 8 per cent. Assuming different depreciation rates for R&D capital has virtually no effect on these results. Differencing estimates improve considerably when growth rates are computed over longer time periods, suggesting that the divergence between time-series and cross-sectional estimates is driven by random measurement errors. The paper also considers differences between high technology and other firms. Cross-section and panel elasticity estimates of the R&D effect diverge considerably for the two groups, while the corresponding rate of return estimators display far less variation. There is some evidence that the R&D elasticity increased during the early 1980s, and that it fell sharply back to its 1979 value during the period from 1985 to 1989.     

R&D spillovers and employment: evidence from European patent data

In this paper we investigate the role of patents in the relationship between R&D activity, spillovers and employment at the firm level. A reduced-form labour demand equation is estimated. Our analysis is based upon a dataset consisting of 879 R&D-intensive manufacturing firms worldwide for which information was collected for the period 2002–2010. We use data from all EU R&D investment scoreboard editions issued every year until 2011 by the JRC-IPTS (scoreboards). Since the innovation output of the industrial strategy of every firm is the number of patents, the main contribution to the existing literature is to investigate also the impact of patents/R&D ratio and patents/spillovers ratio on employment level. The empirical results suggest a significant impact of R&D spillover effects on company employment although the results differ substantially according to the spillover stock, which may considerably affect policy implications.     

Cooperative R&D and Commitment to A Policy of Know-how Trading

In this paper, we develop a theoretical framework to investigate the impact of adopting a strategy of know-how trading on the degree of research and development (R&D) cooperation. We show that the consequences of cooperation in know-how sharing under the conditions of the model are similar to a policy of cooperation in R&D investments in areas with large spillovers. An industry-wide policy of cooperation among competitors with respect to R&D investment and sharing would simply result in maximal joint profits. This cooperative R&D outcome could be generalized to any degree of spillover other than 100%. In this paper, the commitment to a policy of know-how trading by the participants in an industry is explained by the firm’s attempt to induce the equilibrium of a single industry-wide cooperative research joint venture. In a repeated game framework, we show that pre-commitments by non-cooperative firms to disclose their own know-how to the industry can be effective in inducing cooperative R&D investments by the participants.
