We present a model of spatial price discrimination where R&D spillovers are endogenous as they depend on firms' location. We establish that both the distance between locations and R&D efforts are an increasing function of the transportation cost coefficient and show that there is a continuum of cases where firms will choose an intermediate location. The managerial implications from the model are discussed using examples of marketing behavior by Internet retailers. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

Firm performance may be enhanced by linkages with academic institutions, other firms, and foreign markets that confer knowledge spillovers as well as internal R&D that creates firm-specific knowledge. In particular, firm productivity and innovation may be enhanced by positive externalities from knowledge and technology produced by universities and research institutions (URIs) and diffused to the domestic economy. Productive contributions from such linkages might be particularly expected in China, where policy measures have explicitly supported and facilitated connections between URIs and firms to stimulate economic development and competitiveness. In this paper, we measure the performance impact of such knowledge spillovers in Chinese firms by using a variety of specifications, estimators, and robustness checks, including an ??instrumental variable?? specification that controls for endogeneity. We find more patent activity in Chinese firms with URI connections and enhanced firm productivity particularly from linkages with research institutions (RIs). Introduction of new products, processes, and new businesses is also positively associated with linkages with research institutions, as well as with linkages with other firms.  相似文献

This paper investigates firms׳ optimal location choices explicitly accounting for the role of inwards and outwards knowledge spillovers in a dynamic Cournot oligopoly with firms that are heterogeneous in their ability to carry out cost-reducing R&D. Firms can either locate in an industrial cluster or in isolation. Technological spillovers are exchanged between the firms located in the cluster. It is shown that a technological leader has an incentive to locate in isolation only if her advantage exceeds a certain threshold, which is increasing in firms׳ discount rate, in industry dispersion, and in the intensity of knowledge spillovers. Scenarios are identified where although it is optimal for the technological leader to locate in isolation, from a welfare perspective it would be desirable that she locates in the cluster.  相似文献

This paper investigates factors affecting firm performance. Using data from Business Environment and Enterprise Performance Surveys (BEEPS 2013–2014), findings indicate that the following have a positive effect on firm performance: (i) innovative activities; (ii) knowledge spillovers; (iii) foreign ownership; and (iv) the proportion of skilled workers in the workforce. The paper therefore argues that innovation activities are endogenously related to firm performance, and that the performance of firms is influenced by knowledge spillovers and innovation activities, among other firm characteristics. The paper contributes to the literature by identifying spillovers and innovation activities as causal variables of firm performance—a novel approach to investigating knowledge spillovers and innovation activities.  相似文献

In this paper we model growth using a scale-neutral approach to innovation allowing differences between regions to emerge due to regional mechanisms. In this model, agglomeration is growth enhancing as the scale effect for innovation arises from greater access to knowledge rather than any assumed scale effects in growth-modelling techniques. Furthermore, entrepreneurs are assumed to choose the location of firms endogenously so as to minimize the costs of innovation, transport and living. The effects of such mechanisms are such that any policies that increase knowledge spillovers between locations will enhance growth and equality, but may be destabilizing for agglomeration.  相似文献

There is a growing body of research linking knowledge spillovers to strategic entrepreneurship in multiple contexts, yet the existence of purposeful spillovers has been largely ignored. This study analyses the value-accretive potential of knowledge spillover strategies, where a selected body of knowledge is purposefully and strategically disclosed to competitors. The cork industry provides the empirical context, with the many small firms possessing limited innovation capabilities in an industry under threat from rival alternative technologies. The successful fight-back against the onslaught on cork by synthetic and screwcap closures is led by the Portuguese company Corticeira Amorim, the world’s largest stopper manufacturer, whose knowhow then selectively spills-over to the rest of the industry. This multiple-case study involving 14 firms, unfolds in the context of two layers of underlying tensions. By exploring why and how knowledge selectively spillovers across filters from the industry leader to others, and knowledge revealing within small firms, the study contributes to extant literature by extending to the phenomenon of selected and purposeful spillover in the context of capability enhancement.  相似文献

This paper investigates Alfred Marshall’s hypothesis that knowledge spillovers increase where industries are localized. At the same time, we take a fresh look at the role of distance in the diffusion of knowledge spillovers. Relying on a cited-citing gravity-like equation with high-dimensional fixed effects that control for multiple sources of observed and non-observed heterogeneity, we implement a Poisson pseudo-maximum-likelihood (PPML) estimator. We find that knowledge spillovers correlate positively with industry localization and that the agglomeration of an industry can offset the adverse effect of distance. The results also corroborate the distance decay effect uncovered in earlier research. Our new approach to estimate the PPML with two high-dimensional fixed effects should prove valuable in applications to a variety of other problems in economics, such as the estimation of gravity equations widely used in modeling migration, trade and other flows among countries and regions.  相似文献

This paper assesses the impact of Research and Development (R&D) spillovers on production for a panel of 1,203 Italian manufacturing firms over the period 1998–2003.The estimations are based on a nonlinear translog production function augmented by a measure of R&D spillovers which combines the geographical distance between firms, the technological similarity within each pair of firms and the technical efficiency of each firm. The estimation method takes into account the endogeneity of regressors and the potential sample selection issue regarding the decision by firms to invest in R&D. Results show that the translog production function is more suitable than the Cobb-Douglas for modelling firm behaviour and that returns to scale are increasing. Moreover, the internal and external stocks of technology exert a significant impact on firms’ production. Finally, it emerges that, for Italian manufacturing firms, R&D capital and R&D spillovers are highly substitutes.  相似文献

In this paper a simple simultaneous model is constructed to examine whether there are productivity spillovers from both the presence of foreign direct investment (FDI) and competition between local and foreign firms. The model is tested on the data from China’s latest industrial census in 1995. The results indicate that the extent to which spillovers occur varies with different types of ownership of local firms and of FDI. While collective- and private-owned enterprises benefit from demonstration and contagion effects from foreign presence, productivity gains of state-owned enterprises largely come from competition with foreign firms. Productivities of local and foreign firms are jointly determined. Evidence also suggests that market-oriented FDI tends to generate spillovers mainly via competition with local firms.  相似文献

How should an organization be designed in order to provide its members with minimal incentives to defect? And how does the optimal design depend on the type of strategic interaction between defectors and remaining organizational members? This paper addresses such issues in a game theoretic model of cooperation, in which an organization is formally represented by a connected network, and where gains from cooperation are given by a partition function. We show that critical structural features of the organization depend in a clear-cut way on the sign of spillovers. In particular, positive spillovers favor the adoption of dispersed and centralized forms, while negative spillovers favor cohesive and horizontal ones. Moreover, if the organizational form determines all the communication possibilities of members, a highly centralized organization—the star—emerges under positive spillovers, whereas two horizontal architectures—the circle and the complete—emerge under negative spillovers.  相似文献

I study knowledge spillovers in an industry where firms are heterogeneous in their ability to adopt knowledge (absorptive capacity). I set up a model in which firms choose locations anticipating potential gains and losses from other firms’ R&D activity. I apply the model to the US software industry and obtain the following results: the data supports localized knowledge spillovers; firms that have higher absorptive capacity are sorted into more agglomerated counties; ignoring firm heterogeneity leads to biased estimates of gains from spillovers; spillovers play an important role in explaining the geographic distribution of firms, but only within regions with high R&D activity.  相似文献

We study the relationship between a patent-based measure of knowledge spillovers that calculates technological proximity based on technologically relevant firms and innovation success. We find – for a representative sample of Swiss firms – that knowledge spillovers have a positive and significant association with the commercial success of innovative products. The paper shows the importance of market conditions for the relationship of spillovers with innovation performance: It is only positive and significant in markets with a medium number of competitors in the main product market, but not in monopolistic or polypolistic market structures.  相似文献

We examine an asymmetric research and development (R&D) duopoly, where firms differ in their research and development productivity, one firm being technologically advanced. We find that both firms can benefit and increase their profitability by entering into a voluntary information sharing agreement despite their asymmetry and highlight the conditions needed for such an agreement to take place.  相似文献

This paper examines the effect of innovation efficiency on firm performance using the Greek version of the Community Innovation Survey (CIS) 2012–2014 and employs a dataset of 1,274 innovative manufacturing firms. Introducing a data envelopment analysis (DEA)-type benchmarking strategy with non-continuous knowledge inputs, the main findings suggest that innovation efficiency, although does not exert a direct impact on firm performance, moderates the relationship between the internally generated knowledge and firm performance. On the other hand, such a moderation relationship is not confirmed for the relationship between external knowledge and innovation spillovers on firm's performance. Although the impact of the embodied to innovation inputs spillovers, on firm performance, is always positive and significant, empirical results indicate that absorptive capacity exhibits diminishing returns with respect to performance.  相似文献

This article investigates the way in which regions innovate. Its conceptual framework departs from the simple notion that scientific activities equate with knowledge, which assumes that the presence of local knowledge produced by research centres, universities and firms is a necessary and sufficient condition for increasing the innovative capacities in local firms, fed by local spillovers. In particular, the paradigmatic jump in interpreting regional innovation processes lies in a conceptual framework interpreting not a single phase of the innovation process, but the different modes of performing different phases of the innovation process. This article conceptually identifies different territorial patterns of innovation and highlights the context conditions (internal and external to the region) that accompany each innovation pattern. Based on this debate, I express some doubts on the usefulness of EU policy aims for achieving a figure of 3% of the EU's GDP (public and private) to be invested in R&D/innovation and instead strongly support normative suggestions towards thematically and regionally focused innovation policies.  相似文献

Considering oligopolistic contests with R&D spillovers and strategic delegation three results can be obtained: (1) There exist multiple asymmetric equilibria where one owner highly favors sales as a basis for his manager's incentives which drives the other firm out of the market. (2) If R&D spillovers are zero, a managerial firm will have a strong strategic advantage when competing with an entrepreneurial firm. If both owners endogenously decide about delegation, each owner's dominant strategy will be to delegate, given that the manager's reservation value is not too large. (3) If R&D spillovers are maximal, collusive market outcomes become very likely, which makes strategic delegation less important. Copyright © 2004 John Wiley & Sons, Ltd.  相似文献

This paper attempts to use an integrated theory based on the framework of a firm's internal and external sources of knowledge to analyze how R&D activities differ in innovation from non-R&D activities, especially in the context of low and medium-low tech (LMT) sectors where most of the firms are SMEs. Simultaneously, the paper also explores the key differences between R&D and non-R&D innovators. The empirical analysis is based on a representative panel of 2023 Spanish manufacturing firms from the Spanish Ministry of Industry for 2005 and 2006. Innovation in product and process is explained using non-R&D variables such as marketing, design or the hiring of tertiary degree employees. Only innovation in product is explained by R&D expenditures. Regarding innovation in process, the R&D variables work in a few specific cases. Therefore, innovation can be explained using non-R&D variables. The firms with more internal resources, those which conduct R&D activities, present a better absorptive capacity (AC) and this leads them to engage in cooperation agreements and to access external flows of knowledge. The paper has important implications for policymakers due to the fact that most policies for R&D are based just on R&D programmes.  相似文献

According to NEG literature, spatial concentration of industrial activities increases growth at the regional and aggregate level without generating regional growth differentials. This view is not supported by the data. We extend the canonical model with an additional sector producing non-tradable goods which benefits from localized knowledge spillovers coming from the R&D performing industrial sector. This view, motivated by the evidence, generates both an anti-growth and a pro-growth effect of agglomeration for both the deindustrializing and the industrializing regions and leads to two novel results: (1) when agglomeration takes place, growth is lower in the periphery; (2) agglomeration may have a negative effect on the growth rate of real income, both at the regional and at the aggregate level. Our conclusions have relevant policy implications: contrary to the standard view, current EU and US regional policies favouring industrial dispersion might be welfare-improving both at the regional and the aggregate level and may reduce regional income disparities.  相似文献

This research focuses on the behavior of not-for-profit enterprises. In particular, using a familiar model of cost-reducing R&D with spillovers, we examine strategic interactions between labor-managed firms in a duopoly. Research spillovers have not been previously considered in the context of labor-managed firms. Among four market scenarios involving (i) competition in research and production; (ii) cooperation in research and production; (iii and iv) competition or cooperation in research and the reverse in production, our results show that research is greatest under full cooperation, while output is greatest under full competition. Output and R&D are the lowest in the case when firms compete in research, but form a production cartel. The degree of research spillovers has a crucial bearing upon these rankings. Some of these results differ from those for profit-maximizing firms. The effects of changes in research spillovers on employment (output) are shown to depend upon the nature of the underlying production technology. Policy implications are discussed.  相似文献

Statistical evidence suggests that the relevance of knowledge spillovers has increased over time. In this paper we focus on regional knowledge spillovers and adopt a new econometric transformation that allows inference on potential inter-regional knowledge spillovers, accounting for spatial interdependencies.Determinants of inter-regional knowledge spillovers are explained with a sample of 103 Italian provinces. We find that a region’s absorptive capacity, measured by local R&D expenditure and social capital, implies a reduction of outward knowledge spillovers.Identification is based on the use of Two Stages Least Squares and Fixed Effects estimates.  相似文献
