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.  相似文献

This paper presents the effects of an R&D subsidy in a Schumpeterian general equilibrium model with rich industry dynamics. R&D subsidies raise the long-run growth rate, but they also raise the level of industry concentration. In the model firms compete for market share through process R&D endogenously determining the market structure within and across industries. Endogeneity of the market structure allows for analysis of changes in the moments of the firm size distribution in response to policy. R&D subsidies primarily benefit large incumbent firms who increase their innovation rates creating a greater technological barrier to entry. Concentration increases with fewer firms and a higher variance in the market shares. In general equilibrium, the greater distortions in the product market cause the wage rate to fall which leads to increased turnover rates. In addition, the analysis demonstrates that the model captures a large number of empirical regularities described in the industrial organization literature, but absent from most endogenous growth models. These features, such as entering firms are small relative to incumbents, the hazard rate of exit is negatively related to firm size, and large firms spend more on R&D than small firms play important roles in understanding the impact of R&D subsidies on the economy.  相似文献

R&D subsidies are a common tool of technology policy, but little is known about the effects they have on the behavior of firms. This paper presents evidence on the effects that R&D subsidies have on the R&D effort of recipients, and on the probability that a firm will participate in a program granting R&D subsidies. The empirical model consists of a system of equations: a participation equation; and an R&D effort equation. Endogeneity of public funding is controlled for. Estimates are obtained with a cross-section sample of Spanish firms. The main findings are that: 1) small firms are more likely to obtain a subsidy than large firms, probably reflecting one of the public agency's goals; 2) overall, public funding induces more private effort, but for some firms (30% of participants) full crowding out effects cannot be ruled out, and 3) firm size remains related to effort, whether or not a firm gets public funding.  相似文献

This paper is one of the first attempts in the literature to evaluate the effectiveness of R&D policies in Europe during the great crisis of the late 2000s. Using homogenous firm-level data for the largest EU Member States over the period 2007–2009, we test whether manufacturing firms receiving public subsidies spent more on R&D. The analysis is performed using both non-parametric techniques and parametric estimation methods accounting for the possible endogenous selectivity of R&D subsidies. The hypothesis of full crowding-out is rejected in all countries under exam as firms did not replace their own resources with public grants. However, these firms did not allocate additional funds to research and hence, differently from earlier works, we do not find evidence for additionality effects of R&D subsidies. Our estimates indicate that, albeit not expansive, public subsidies to R&D thwarted the reduction of firm R&D efforts in the aftermath of economic crisis.  相似文献

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.  相似文献

This paper analyses the question of optimum R&D subsidies in the context of a two-stage asymmetric Cournot duopoly model with endogenous R&D. For the special case of symmetric duopoly, whether the firms should be subsidized or taxed in their R&D activities crucially depends on the concavity/convexity property of the demand function. It is also shown that a firm with some initial cost advantage should be subsidized in its R&D activities and a firm without should be taxed. In this way, we obtain policy implications that cast doubts on the universal applicability of competition policies.

Whereas the provision of R&D subsidies has been central to public policy for many years, governments have recently become increasingly involved in stimulating cooperation for innovation and R&D. In many countries, financial support for technology intermediaries has become one of the key measures of indirect public support. However, little research has assessed the impact of indirect policy measures. In this paper, we shed light on the conditions under which technology intermediaries contribute to knowledge and networking outcomes generated by the firms that call upon them. We hereby focus on firm network and competence additionality as measures for cognitive capacity additionality and study the impact of technology intermediaries on firms. In doing so, we distinguish between R&D and R&D related activity technology intermediaries engage in. The results indicate that absorptive capacity of the technology intermediary does not affect cognitive capacity additionality generated by firms in R&D activities, while the results for R&D related activities are mixed and depending on the type of cognitive capacity additionality studied. The absorptive capacity of firms does not directly affect cognitive capacity additionality, but the results of mediation analysis show that firms with higher levels of absorptive capacity use the services of the technology intermediary more intensively, and subsequently generate higher levels of cognitive capacity additionality.  相似文献

We analyse the impact of public subsidies on private sector research and development (R&D) activity for a sample of East German firms. Using propensity score matching, our empirical results indicate that subsidized firms indeed show a higher level of R&D intensity (R&D expenditures relative to total turnover) and a higher probability for patent application compared with non‐subsidized firms. We find that, on average, the R&D intensity increases from 1.5% to 3.9%. The probability of patent application rises from 20% to 40%. These results closely match earlier empirical findings for East Germany. Given the fact that the East German innovation system is particularly driven by small‐ and medium‐sized enterprises (SMEs), we draw special attention to the effectiveness of R&D subsidies for this latter subgroup. Here, no specific empirical evidence is available so far. Our findings indicate that policy effectiveness also holds for private R&D activity of SMEs, with the highest increase in terms of R&D intensity being estimated for microbusinesses with up to ten employees.  相似文献

Many studies have established the importance of investment in R&D to facilitate innovation and consequently improve firm productivity. Firms decide whether or not to undertake R&D depending on a range of factors such as market orientation, business objectives, competitive advantages and absorptive capacity. This paper studies the factors that influence this decision in peripheral locations; and for firms that do not undertake R&D, we analyse the reasons for not doing so. The research is based on data from a survey of some 250 matched firms operating in Northern Ireland, about half undertaking R&D and half not. Northern Ireland is an interesting case study because it exhibits a low level of investment in R&D despite the public subsidies and policy initiatives that have existed over the last 30 years. For firms that undertake R&D, our results mostly confirm the findings of others while for firms that do not undertake R&D the results point to a capabilities-gap rather than a resource-gap as the fundamental problem. Policy conclusions are drawn as to what might be done to boost both the amount of R&D undertaken and the number of firms engaged in R&D in peripheral regions.  相似文献

Although the econometric evaluation of R&D has attracted wide interest in many countries, it has not attracted much in the UK. The main objective of this paper is to fill this void, i.e., to estimate the impact of R&D on productivity growth of the UK manufacturing sector. However, there are some additional objectives. Firstly, we estimate the impact of R&D on productivity growth of large and small firms and we discuss a number of theoretical arguments regarding the role of firm size. Secondly, given that the technological infrastructure influences the innovative capacity of a firm, we compare the impact of R&D on productivity growth of high-tech firms with the corresponding impact on productivity growth of low-tech firms. Thirdly, we investigate whether the contribution of R&D to productivity growth has changed over time.

Based on firm-level data (78 firms, 1989–2002), we find that the contribution of R&D is approximately 0.04. Although the R&D-elasticity of large firms (0.044) is higher than the corresponding elasticity of small firms (0.035), the difference is small. In contrast, the R&D-elasticity is considerably high for high-tech sectors (0.11), but statistically insignificant for low-tech sectors. Finally, the investigation of the elasticity of R&D over time revealed an interesting discontinuity showing that although until 1995 the R&D-elasticity was approximately zero, after 1995 it increased dramatically to 0.09. We investigate the potential causes of such non-linearity and we suggest a number of possible explanations.  相似文献

Equity financing is the optimal strategy for innovating firms, which can use their financial structure as a signalling device to attract outside investors. This situation is likely to arise when the firm undertakes a specific purpose R&D project aimed at developing a certain product innovation. Typically, innovations of this kind draw on the firm's cumulative. idiosyncratic knowledge base and, accordingly, the innovation process involves an high degree of asset specificity. Under such circumstances, the terms of debt financing will be adjusted adversely, and equity financing will represent the most economically efficient solution.

These arguments are developed in standard static principal-agent models dealing with New Technology Based Firms and publicly held large firms undertaking an aggressive R&D strategy. In the case of NTBFs, two kinds of optimal venture capital contracts are considered, which render the sharing rules independent (a) of the agent's action and (b) of both the agent's action and the specific assets involved in the transaction. Regarding innovating large firms, it is argued that in this case, too, equity represents the optimal financing strategy, and that top executives use their equity share to signal the firm's expected return stream and value to outside investors.  相似文献

ABSTRACT

This paper examines how efficiently different groups of firms use their R&D expenditures. To this end, it investigates how the empirical relationship between firms' R&D expenditures and their sales growth varies with different values of firm size, firm age, and the number of firms in the respective industry. Using panel data for Switzerland ranging from 1995 to 2012, the paper finds that smaller, more mature firms show a more positive relation between R&D expenditures and sales growth than both relatively larger or younger firms. The paper argues that, on the one hand, these firms can benefit from various small size advantages in the R&D process, such as more motivated researchers, caused by a stronger connection to the firm's fate. On the other hand, these firms can also benefit from a well-established R&D department that allows absorbing the latest technological developments. The paper further finds that industries consisting of many small firms show a more positive relation between R&D expenditures and sales growth than industries consisting of only a few large firms. The intuition behind this result is that industries consisting of many small firms imply more independent innovative trials, which then together result in a higher probability of discovering successful innovations. In sum, the paper finds that groups consisting of a large number of small, more mature firms spend their R&D in the most efficient way.  相似文献

We analyze the influence of innovation on growth rates of employment in 859 Dutch manufacturing firms over the period 1983–1988. Whereas the (growth of the) R&D intensity of firms has a slightly negative impact on employment, we find that firms with a high share of product-related R&D (as a proxi of R&D related to industrial activities in an early stage of the life cycle) experienced an above average growth of employment. The same holds for firms which directed their R&D towards information technology. Smaller firms have, ceteris paribus, substantially higher growth rates of employment than their larger counterparts. Against our expectations, R&D cooperation has no significant impact on employment growth. The same holds for activities in the fields of biotechnology and new materials.  相似文献

This article studies the influence of corporate governance factors on firm R&D investment in a transitional economy like China. By using the data from the listed companies in China, this article statistically tests the hypotheses on the relations between corporate R&D intensity and managerial discretion of CEOs, independent outside directors, degree of share concentration, share held by the state, and share held by a manager. According to the results, the managerial discretion of CEOs has a significant and negative correlation with the firm R&D investment. The number of the independent outside directors in the board has a positive influence on the R&D investment. And as the shares held by a manager increase, the firm R&D intensity will decrease at first, and then increase along an inverted parabolic curve. All these findings show that the improvement of corporate governance and stock incentive plan, and the cultivation of active and long-term stock investors, may finally lead to the upgrade of corporate innovation capabilities.  相似文献

In this paper, we define public technology infrastructure to mean public resources that bring new R&D into existence. Examples are public research that yields knowledge spillovers and government contracts that broker new research. Using this definition we explore the effect of public infrastructure on cooperative R&D, especially R&D sourcing and research joint ventures (RJVs). Our findings strongly suggest that public infrastructure promotes cooperative R&D. We begin by studying the role of federal laboratories in R&D sourcing by private laboratories, finding that sourcing increases as a result. Then we examine patents arising from RJVs sponsored by the Advanced Technology Program (ATP). We find that R&D subsidies as well as difficulty and novelty increase patents produced by the RJVs. Contractual oversight by ATP has no direct effect but an indirect effect appears to exist, since firms value ATP oversight more highly for more difficult and novel projects, and these produce more patents.  相似文献

R&D competition, absorptive capacity, and market shares   总被引:3,自引:0,他引:3  
This paper deals with an oligopolistic industry where firms are engaged in cost-reducting R&D activity to maximize their market shares. The existence and uniqueness of a feedback-Nash-optimal R&D strategy for each firm are discussed. Our simulations highlight that variations in spillovers hardly influence the firms' R&D investment, if their absorptive capacities to exploit extramural knowledge depend on their R&D efforts. Moreover, extramural knowledge cannot completely replace in-house R&D. However, a high level of public R&D favors the firm with the most restrictive R&D expenditure constraint and/or with the lowest initial R&D stock, provided it invests in R&D.  相似文献

We propose a general theory of innovation that illustrates the relative benefits of performing process versus product R&D when firm size is endogenous. A firm's size, scope, and R&D portfolio are shown to reflect the same underlying characteristic of the firm, namely manufacturing efficiency. We demonstrate that efficient firms become larger, have greater scope, and perform more of both process and product R&D. In light of decreasing returns to R&D, this implies small firms obtain more product innovations per dollar of R&D than large firms, which is consistent with evidence we present that small firms are more innovative than large firms as they obtain more patent counts and citations per dollar of R&D.  相似文献

This article analyses the effects of public R&D subsidies on R&D input and output of German firms. We distinguish between the direct impact of subsidies on R&D investment and the indirect effect on innovation output measured by patent applications. We disentangle the productivity of purely privately financed R&D and additional R&D investment induced by the public incentive scheme. For this, a treatment-effect analysis is conducted in a first step. The results are implemented into the estimation of a patent production function in a second step. It turns out that both purely privately financed R&D and publicly induced R&D show a positive effect on patent outcome.  相似文献

Using a comprehensive dataset covering 42 countries spanning 2002–2013, this paper empirically examines the effect of environmentally sustainable practices (ESP) on R&D intensity in firms. We use three separate firm-level ESP scores that distinguish between the mandatory and voluntary compliance of environmental regulations mandated within an industry and a country. Our main finding is that an increase in ESP increases R&D intensity. Therefore, ESP encourages a higher number of innovations and there is a negligible trade-off between these two factors of firm performance. Further, the positive effect of ESP is stronger in countries where institutional quality and R&D infrastructure supports are superior. Our results have important policy implications for firms, investors and national governments.  相似文献

This work studies the effects of R&D activities and investment, both physical and R&D, on the growth of firms by considering a dynamic firm growth model with serial correlation. The main hypotheses maintain that firms with a strong commitment to R&D have a higher growth rate, and investment has a positive effect on firm growth. We investigate such relations with reference to an unbalanced panel data set of Portuguese manufacturing firms over the period of 1990 to 2001. We find that a systematic tendency for smaller firms to grow more quickly is the main reason why firm growth is not entirely stochastic.  相似文献
