A theoretical and widely-quoted finding is that levels of cooperative R&D exceed noncooperative R&D levels when technological spillovers are relatively large, while the opposite holds for relatively small technological spillovers. We qualify this result by showing that for relatively small technological spillovers the comparison is not driven by the extent of technological spillover, but by the increase in technological spillover due to cooperation in R&D. In particular, an agreement to cooperate in R&D always raises R&D efforts if the post-cooperative technological spillover rate is high enough.  相似文献

The paper analyzes, in a model of quantity-setting three firms, the interaction between cooperation decisions at the R&D stage and merger decisions at the production stage. We assume that only two of the three firms are capable of doing cost-reducing research. Two types of cooperative research, viz., the knowledge-sharing agreement and research joint venture are considered. Cost reduction in the case of a successful research joint venture is larger compared to knowledge sharing or independent research, due to possible synergies. We show that allowing mergers can change the organization of the R&D process, and admitting cooperative research can affect the occurrence and nature of mergers at the production stage.  相似文献

In this paper a model of multistage R&D patent policy is investigated. We study the impact of the duration of patent protection for intermediate products on R&D races when the discovery of the final product requires the accomplishment of an intermediate step. Using a multistage model where firms choose their levels of research investment at each stage, we find all subgame-perfect equilibria of the game. We also determine how competition affects a firm's level of research investment at different stages of the R&D competition.  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 consider a differential game of R&D competition and explore the impact of rivalry on the firms' investment behavior over time. Using closed-loop strategies and hence allowing for strategic interactions among rival firms we show that R&D spending by the individual competitor is increased due to competition in the race for priority. This leads us to argue that competitive encounters enhance R&D activities at the same time as increasing efficiency in the race for a technological breakthrough.  相似文献

Cooperation and the efficiency of regional R&D activities   总被引:7,自引:0,他引:7  
This paper investigates the relationship between the cooperativebehaviour of manufacturing establishments in a region and theefficiency of their R&D activities, using data for 11 Europeanregions. Some significant differences in the attitude towardsR&D cooperation as well as with regard to the efficiencyof R&D activities between the regions can be found. However,these two issues appear to a large degree to be empiricallyunrelated. Therefore, the role of R&D cooperation in regionalinnovation systems remains unclear.  相似文献

The Long-Run Growth Effects of R&D Subsidies   总被引:4,自引:0,他引:4  
This article presents a generalized versionof Howitt's (1999) model of R&D-driven growth withoutscale effects and a complete characterization of the long-rungrowth effects of R&D subsidies. R&D subsidiescan either promote or retard long-run economic growth, and surprisingly,the growth-retarding outcome occurs for a wide range of plausibleparameter values. This article also presents a new intuitiveexplanation for why R&D subsidies can have long-rungrowth effects (both positive and negative).  相似文献

Technology spillover and research and development (R&D) budget are relevant on government subsidies that aim at improving social welfare through enhancing R&D incentives of firms. However, there has not been related literature considering these two factors. To fill this gap, this paper examines the effect of technology spillover and R&D budget on R&D competition of duopolistic firms and government subsidies by constructing a game-theoretic model. We find that while each firm's profit sometimes increases with R&D budget for low coefficient of technology spillover, this profit may decrease with R&D budget for high coefficient of technology spillover due to the intensified R&D competition. We show that when both R&D budget and the coefficient of technology spillover remain high, R&D subsidy leads to higher social welfare than output subsidy and otherwise R&D subsidy results in lower social welfare.  相似文献

This paper analyses strategic R&D policy in a third-country trade model where multiproduct firms with different production technologies compete in a vertically differentiated market. I show that the optimal R&D policies for both countries are subsidies when the product market is under price competition.  相似文献

Abstract

We have investigated non-cooperative and jointly optimal R&D policies in the framework of Spencer & Brander (1983) in the presence of R&D spillovers. When R&D activities are strategic substitutes and the R&D game exhibits a positive externality, the result of Spencer & Brander (1983) reverses: the non-cooperative policy is a tax while the jointly optimal policy is a subsidy. Moreover, when R&D activities are strategic complements, the usual result of the prisoners' dilemma in the strategic subsidy game does not hold, implying that a welfare intervention is preferable over laissez-faire. When spillovers are sufficiently large, the joint welfare increases with subsidies being higher than those under non-cooperation.  相似文献

Environmental Research Joint Ventures under Emission Taxes   总被引:1,自引:0,他引:1  
The effect of environmentalpolicy depends crucially on the strategicbehavior of firms. Firms can undertakepollution abatement innovation cooperativelythrough environmental R&D joint ventures(RJVs). Environmental RJVs have not onlyenvironmental but also economic impacts. Threetypes of environmental RJV are discussed inthis paper: R&D cartelization in which firmschoose R&D efforts to maximize the jointprofit, RJV competition in which firms sharethe R&D fruits to maximize their own profits,and RJV cartelization in which firms share R&Dfruits and maximize the joint profit. An R&Dcartelization minimizes output quantities,maximizes the total emission, and minimizes thesocial surplus. An RJV cartelization with asufficiently high spillover coefficientmaximizes R&D efforts, minimizes the totalemission, and maximizes the social surplus.  相似文献

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market.  相似文献

This study examined the moderating effects of two kinds of internal R&D (parent R&D and subsidiary R&D) on the relationship between local R&D outsourcing and subsidiary productivity as internal R&D challenges the collaborative relationships in the local environment. Due to the specific feature of a subsidiary mandate, we further investigate whether two distinct kinds of internal R&D have different moderating effects between exploitation-oriented subsidiaries and exploration-oriented subsidiaries, based on a sample of longitudinal data set of 263 Taiwan-based manufacturing subsidiaries over the period 2006–2009. The empirical results show that for exploitation-oriented subsidiaries parent R&D plays a significant and negative moderating role on the impact of local R&D outsourcing based on local collaboration, while a positive moderating role is observed with parent R&D and subsidiary R&D for exploration-oriented subsidiaries.  相似文献

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.  相似文献

Prior studies implicitly assume that knowledge search modes are homogeneous, and little is known about the impacts of specific search modes on innovation. Drawing upon the knowledge search literature, we differentiate among four types of search modes and analyze their impacts on innovation performance. Moreover, we enrich the theoretical framework by recognising the moderating role of strategic R&D orientation in affecting the relationship between specific types of search modes and innovation performance. Using a unique dataset of 418 Chinese firms, we find that, except for inward licensing, value chain search, capital search, and industry-university-research institute collaboration (IUR collaboration) exert positive effects on innovation performance. Moreover, the empirical results indicate that a strategic R&D orientation amplifies the positive effects of value chain search and IUR collaboration while it mitigates the negative effect of inward licensing on innovation performance.  相似文献

This paper studies incentives for cooperative research vis-à-vis non-cooperative research in an incomplete information framework. We show that with quantity competition under asymmetric information, the expected payoff from non-cooperative research goes down compared to the case of symmetric information; hence research joint venture incentives of the firms are larger under asymmetric information. In either case, however, the larger is the size of the cost-reducing innovation the lower is the incentive for cooperative research. Finally, in our model, incomplete information does not affect the consumers' welfare, but the firms become worse off.  相似文献

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.  相似文献

R&D spillovers and productivity: Evidence from U.S. manufacturing microdata   总被引:1,自引:0,他引:1  
This paper deals with the estimation of the impact of technology spillovers on productivity at the firm level. Panel data for American manufacturing firms on sales, physical capital inputs, employment and R&D investments are linked to R&D data by industry. The latter data are used to construct four different sets of `indirect' R&D stocks, representing technology obtained through spillovers. The differences between two distinct kinds of spillovers are stressed. Cointegration analysis is introduced into production function estimation. Spillovers are found to have significant positive effects on productivity, although their magnitudes differ between high-tech, medium-tech and low-tech firms.

In a dynamic patent race model we analyze the formation and breakup of joint ventures in relation to: (a) the relative as well as absolute position of the firms in the race; (b) the degree of competition in the ex post market. Fudenberg et al. (1983) studied the main features of a patent race when firms compete in R&D, showing that firms in the same position compete fiercely, dissipating the rent from innovation. By contrast, we show that if firms can cooperate or compete in R&D, and if they start in the same position, they cooperate at the outset but break their agreement in the last stage if they will be serious competitors in the downstream market, while, if they can collude in the ex post market, they cooperate from the outset and they innovate jointly. When the firms are lagged by one step, cooperation does not take place, except in the case the value of the race is negative and the cost saving due to cooperation is large. However, cooperation never occurs if the leader is more than one step ahead. Finally, when the firms cooperate in R&D they proceed to the discovery at low speed. We test these conclusions via experiments on the incentive to cooperate during the course of a race. The results of a sample of 86 races support our theoretical conclusions, although the experimental findings are less clear-cut than the theoretical ones.  相似文献

We compare the subgame perfect equilibrium emerging in four regimes of research and development (R&D) competition between duopolists: (i) full competition, (ii) coordination of research strategies, (iii) joint venture with cross licensing of patents, and (iv) full collusion in R&D and the product market. The outcome of the firms' interaction depends on the interplay of the degree of product market competition, the similarity of the research strategies, and the cost of R&D, relatively to market size. Our main result is that each of the four regimes can, for plausible parameter combinations, yield the highest level of welfare. Therefore it is problematic to draw general rules applicable to all proposed research joint ventures.  相似文献
