Incumbent firms have two basic possibilities to improve their competitive position in the product market: Investment in R&D and the creation of entry barriers to the disadvantage of potential rivals, e.g. through lobbying activities, campaign contributions, bribes or the adoption of incompatible technologies. This paper proposes a simple oligopoly model which raises the possibility that such anti-competitive conduct and R&D investment are complementary activities for incumbents. Consequently, an institutional framework or technological possibilities which encourage anti-competitive conduct, although impeding entry of potential rivals and accentuating standard oligopoly distortions, may foster R&D-based growth and welfare. However, this outcome is less likely if entrants exert technological spillover effects, e.g. through foreign direct investment. Stronger protection of intellectual property rights, although triggering anti-competitive conduct and thereby impeding market entry as well, is more likely to foster economic growth. 相似文献

Abstract . We examine firms' incentives to protect their non-cooperative R&D investments from spilling over to competitors. We show that, contrary to findings in most of the literature, the lack of full appropriability can lead to an increase in R&D investments. Consequently, as long as the R&D spillovers are not too strong, firms decide to let their R&D knowledge flow. Since, as we show, welfare is higher when R&D spillovers are present, it follows that public policies that promote the dissemination of technological knowledge could be welfare-enhancing. 相似文献

Firm success is often associated with the development of better products. Private firms undertake applied R&D seeking market advantage, by capitalizing on the freely accessible results of basic research. But unpatentable basic research often fails to address applied R&D open problems. What is the role of the incentives in improving the innovative performance of an economy by matching partially motivated public researchers to their mission? Sometimes government-funded research projects are mission-directed, and yet in many cases the public sector academics indulge in carrier-driven research. An innovation system where, as in the United States, basic research is also driven by patents implicitly sets an ex-post incentive to the researchers guided by invisible hand. For a public innovation system – like the European one – designing an incentive scheme to motivate public researchers is of key importance for fostering the performance of the economic system. This paper extends the Schumpeterian multisector growth model with vertical innovation by highlighting a link between the degree of 'targetness' of public research and aggregate innovation. A positive effect of social capital is also proved. 相似文献

By allowing for investment activities by research and development (R&D) firms to prevent product obsolescence, we show that if legal patent protection is too strong, a higher R&D subsidy rate delivers insufficient investments for survival in the R&D sector, depressing innovation and growth in the long run. 相似文献

Abstract. This paper analyses R&D cooperation with asymmetric spillovers. It is shown that the change in R&D by a firm following cooperation is proportional to the gap between the spillover rate transmitted by that firm and a critical level of spillovers. In consequence, cooperation increases total R&D investments when the average of firms' spillover rates is sufficiently high. Whereas with symmetric spillovers cooperation is always beneficial to firms, with asymmetric spillovers only a very limited range of spillovers makes cooperation beneficial to both firms. Asymmetries also create a potential conflict between maximizing total welfare and maximizing effective cost reduction. JEL classification: L13, O33 相似文献

This paper analyzes the normative side of an R&D growth model in which market structure and growth are jointly determined in the equilibrium of a one‐sector economy under monopolistic competition. We find that a distortion in the allocation of R&D, namely the presence of technological spillovers between firms, generates two market failures: insufficient growth and excessive entry of firms. We show that this result is driven by the interplay between market structure and growth. A simple tax/subsidy scheme to support the efficient solution is proposed. 相似文献

We construct a two-country North-South Product-cycle model of trade with endogenous growth and trade barriers. We remove the scale effects on growth by incorporating rent protection activities by Northern incumbents. We examine the effects of two forms of globalization - an expansion of the relative size of the South and unilateral trade liberalization by either country. We find that the location of rent protection institutions and the sectoral trade structure determine whether or not globalization raises steady-state economic growth. We demonstrate that for accelerating worldwide economic growth, contrary to conventional wisdom, unilateral Northern trade liberalization is preferable to bilateral trade liberalization. 相似文献

Whether international R&D spillovers are global and trade-related is still a debated issue. By adopting two specifications that nest models previously estimated in the literature, we test the hypothesis that international R&D spillovers are global and trade-unrelated for a sample of OECD countries over the period 1971–2004. In particular, via a randomization exercise, we reject the null hypothesis of a “global pool of technology” and show that there are partitions of countries associated with relatively strong/weak knowledge spillovers. Then, we estimate a nonlinear specification that includes simultaneously geographical distance and international trade among the determinants of domestic TFP. We find robust evidence that both factors affect how foreign knowledge impacts on the domestic productivity of each recipient country. 相似文献

We define a notion of stability of equilibrium in an infinitely repeated step-by-step R&D race. The unique symmetric equilibrium is shown to be unstable, and stable asymmetric equilibria arise, if product market competition is intense, firms are patient, imitation is difficult and innovations are large. Some predictions based on symmetric equilibria, e.g. that less patient firms always invest less in research, or that more intensive competition leads to higher economic growth, are reversed for “realistic” values of the underlying parameters. 相似文献

This note suggests that the association between income inequality and economic growth rates might arguably depend on the political ideology of incumbent governments. Estimates indicate that under leftwing governments, inequality is negatively associated with growth while the association is positive under rightwing governments. This may provide a qualification to recent studies of inequality. 相似文献

After a decade of research on the relationship between institutions and growth, there is no consensus about the exact way in which these two variables interact. In this paper we re-examine the role that institutions play in the growth process using data for developed and developing economies over the period 1975–2005. Our results indicate that the data is best described by an econometric model with two growth regimes. Political institutions are the key determinant of which regime an economy belongs to, while economic institutions have a direct impact on growth rates within each regime. These findings support the hypothesis that political institutions are one of the deep causes of growth, setting the stage in which economic institutions and standard covariates operate. 相似文献

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. 相似文献

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. 相似文献

Using R&D-based models of economic growth as a foundation, this paper argues that market-driven knowledge creation is necessarily linked as an engine of productivity growth to economies of scale and market-power. A cost function and factor demand model is applied to a cross-country industry data set to study market-power, economies of scale and the role of knowledge in an integrated approach. Empirical results reveal the presence of market-power and economies of scale in all of the industries investigated. R&D and spillovers explain some of the productivity growth observed. Spillovers are identified as an external source of economies of scale. 相似文献

Abstract. We analyze a situation where a principal wants to induce two firms to produce an output, for example electricity from renewable energy sources. Firms can undertake non-contractible investments to reduce production cost of the output. Part of these investments spills over and also reduces production cost of the other firm. Comparing a general price subsidy and an innovation tournament, we find that the principal's expected cost of implementing a given expected output is always higher under the tournament, even though this scheme may lead to more innovation. 相似文献

This paper discusses the impact of oligopolistic product markets for innovation and growth, highlighting a novel, fundamental role of spillovers. We develop a model of endogenous growth with non-tournament R&D, where spillovers raise the relative R&D efficiency of laggards. A key feature is that the rate of innovation and the market configuration (i.e. the distribution of market shares) are jointly determined. Our results emphasize the role of spillovers in sustaining the competitive pressure that is fundamental for long-run innovation and economic growth. 相似文献

This paper proposes an alternative theory for the observed persistence in income inequality across households, a theory based on limited parental altruism. We argue that the degree of parental altruism is ‘limited’ by the economic status of the parent. A poor parent not only has less ability, but also has less willingness to invest in children's human capital formation. This generates a non-linearity in such investment expenditures. As a result, initial income differences may perpetuate over time—even with convex technology and convex preferences. In this context, we also compare the efficacy of the public vis-à-vis the private education system from the perspective of long run growth. 相似文献

This paper empirically examines whether there exists stochastic convergence of income inequality among 48 contiguous states within the US over the 1916–2005 period. For that purpose, we employ the recently developed panel stationarity test of Carrion-i-Silvestre, Del Barrio-Castro and López-Bazo (2005), which assumes a highly flexible trend function by incorporating an unknown number of structural breaks. In addition, the issues of cross-sectional dependence as well as control for finite-sample bias are accommodated through bootstrap methods. Overall, for the US case, our analysis provides strong evidence in support of the hypothesis of inter-state inequality convergence. Moreover, the results are robust to alternative inequality measures applied, different notions of stochastic convergence defined, and alternative panel stationary test employed. 相似文献
