Inter-firm complementarities in R&D: a re-examination of the relative performance of joint ventures

We compare duopoly outcomes between two alternative modes of research and development (R&D), viz. independent R&D and non-cooperative research joint ventures (RJVs), when there are complementarities between firm-specific R&D resources. When complementarity is high, RJVs lead to higher technological improvement and the reverse holds for low complementarity. In the intermediate range, the comparison depends on the relative imperfection in spillovers afflicting independent R&D. In sharp contrast to results on cooperative RJVs, non-cooperative RJVs lead to higher technological improvement when spillovers affecting independent R&D are low; the reverse holds for high spillovers. When RJVs yield higher technological improvement, they also yield higher industry profit and social welfare.     

The welfare effects of cooperative R&D in oligopoly with spillovers

This paper provides a more complete characterization of the welfare effects of cooperative cost-reducing R&D investments in Cournot oligopoly with spillovers. I show that R&D cooperation reduces both R&D spending and social surplus when the spillover rate in R&D is neither sufficiently high nor sufficiently low. As the elasticity of the slope of the inverse demand function increases, however, the set of spillover rates over which cooperative R&D reduces social welfare shrinks, and in the limit, cooperative R&D is socially beneficial for all spillover rates.     

Cost Reduction,Competitive Pressure and Firms' Optimal R&D Strategies in a Duopolistic Industry

This paper deals with a duopolistic industry where firms are engaged in cost-reducing R&D activity in order to maximize their market shares. Firms' R&D competition is characterized as a dynamic noncooperative feedback game where the optimal strategies are affected by the extra-industry R&D activity and the degree of intra-industry spillovers. Numerical simulations highlight the importance of the assumptions on the firms' absorptive capacity (to exploit external knowledge) in determining the optimal levels of firms R&D investrnents.     

Cooperative R&D between vertically related firms with spillovers

This paper analyzes the effects of cooperative R&D in two vertically related duopolies, which are two final-good manufacturers and two input suppliers, with horizontal and vertical spillovers. Vertical R&D cartels yield a larger social welfare than non-cooperative R&D and, if the horizontal spillover rate between the input suppliers is not sufficiently high, than horizontal R&D cartels. Technological improvement is accelerated by forming vertical research joint ventures (RJVs), whether or not their member firms' R&D decisions are coordinated. Vertical RJV cartels yield the largest social welfare when the vertically related firms can coordinate their R&D decisions and/or share useful knowledge fully.     

Heterogeneity in R&D cooperation strategies

We explore heterogeneities in the determinants of innovating firms' decisions to engage in R&D cooperation, differentiating between four types of cooperation partners: competitors, suppliers, customers, and universities and research institutes (institutional cooperation). We use two matched waves of the Dutch Community Innovation Survey (in 1996 and 1998) and apply system probit estimation. We find that determinants of R&D cooperation differ significantly across cooperation types. The positive impact of firm size, R&D intensity, and incoming source-specific spillovers is weaker for competitor cooperation, reflecting greater appropriability concerns. Institutional spillovers are more generic in nature and positively impact all cooperation types. The results appear robust to potential simultaneity bias.     

Market failures and the additionality effects of public support to private R&D: Theory and empirical implications

We extend the theoretical basis of the empirical literature on the effects of R&D subsidies by providing an estimable model of strategic interaction among subsidy applicants, and public and private sector R&D financiers. Our model incorporates fixed R&D cost and a cost of external finance. We derive the optimal support rule. At the intensive (extensive) margin the costs of external funding reduce (increase) the optimal subsidy rate. We also establish necessary and sufficient conditions for the existence of additionality. It turns out that additionality at the intensive margin is less likely with higher spillovers. Our results suggest that the relationship between additionality and welfare may not be straightforward.     

FDI and quality-enhancing technology spillovers

When Northern firms undertake FDI in the South, their superior technology spills over to Southern firms and enables Southern firms to enhance their product quality. This paper explores quality-enhancing technology spillovers in an international duopoly model of vertical product differentiation. We find that the Northern firm strategically reduces its product quality to limit the amount of technology spillovers upon FDI. The trade-off between the Northern firm’s endogenous product quality choice and technology spillovers—similar to that between R&D and technology spillovers as discussed previously–plays a critical role in welfare consequences and policy implications of quality-enhancing technology spillovers.     

Endogenous Spillovers and the Performance of Research Joint Ventures

We present a model of R&D with endogenous spillovers and demonstrate that noncooperation can produce maximal spillovers. The only other noncooperative outcome is minimal spillovers. When noncooperation achieves maximal spillovers so does an RJV, whereas minimal noncooperative spillovers imply partial—but not necessarily maximal—spillovers by an RJV. Partial RJV spillovers are chosen for anti-competitive reasons and an RJV may also close a lab for anti-competitive reasons. The possibility of anti-competitive outcomes is precluded in the existing literature on RJVs which focuses on symmetric outcomes. Our model predicts when anti-competitive behaviour by an RJV arises.     

A Structural Empirical Model of R&D,Firm Heterogeneity,and Industry Evolution*

This article develops and estimates an industry equilibrium model of the Korean electric motor industry from 1991 to 1996. Plant-level decisions on R&D, physical capital investment, entry, and exit are integrated in a dynamic setting with knowledge spillovers. We apply the novel approximation of oblivious equilibrium to estimate the R&D cost, magnitude of knowledge spillovers, adjustment costs of physical investment, and plant scrap value distribution. Knowledge spillovers are essential to explaining the firm-level productivity evolution and the equilibrium market configuration. A $15\%$ R&D subsidy maximizes industry output and is broadly consistent with a past policy initiative of the Korean government.     

Growing in the changing global landscape: the intangible resources and performance of high-tech corporates

The Belt and Road Initiative and Sino-US trade war stand for the trend of globalization and de-globalization. The changing environment motivates innovative high-tech corporates to reassess their intangible resources such as R&D investment and top managers team (TMT) political ties, in order to attain competitive advantages. The study based on a sample of 223 listed Chinese most innovative high-tech corporates (2014–2018) confirms R&D intensity as burden and political ties as support for corporates’ short-term performance. TMT political ties may attenuate the negative effect of R&D intensity on performance. The negative influences of R&D are aggravated when high environmental dynamism in both the US and B&R countries markets. However, the positive influences of political ties are moderated differently by environmental dynamism in the two markets. For the US market, export environmental dynamism implies de-globalization and diminishes the positive effect of the political relations on performance. By contrast, for the B&R market, it suggests globalization and strengthens the positive effect of political ties.

     

Business R&;D and the Interplay of R&;D Subsidies and Product Market Uncertainty

This paper examines the effect of product market uncertainty and government research and development (R&D) subsidies on firm-level R&D investment. Using a sample of German manufacturing firms, we find that product market uncertainty reduces R&D investment and government R&D subsidies increase R&D investment. Moreover, our results indicate that R&D subsidies mitigate the effect of product market uncertainty on R&D investment. These findings suggest that public policies aimed at increasing business R&D investment can achieve this objective by reducing the degree of uncertainty in the product market.      

Common ownership,market power,and innovation

I examine the effects of overlapping ownership on market power when there are external effects across firms. This is done in an oligopoly model with cost-reducing innovation with technological spillovers where firms have an overlapping ownership structure based largely on López and Vives (2019). The model allows for Cournot competition with homogeneous product and for Bertrand with differentiated products as well as for strategic effects of R&D investment. It derives positive testable implications and normative results to inform policy.     

From Which Source Do Small Firms Derive Their Innovative Inputs? Some Evidence from Italian Industry

This paper relies upon the hypothesis that the “knowledge production function” – defined in the geographical sense – is characterized by coefficient estimates which vary with firm size. In particular, large firms depend for their innovative output on direct and indirect R&D inputs, whereas small firms more extensively exploit the spillovers from research activities carried out by universities and by other firms. This hypothesis is tested against two different sets of data: the first based on patent statistics and dealing with 20 Italian regions over the period 1978–86; the second consisting of a selected number of product innovations identified by a literature-based counting procedure and dealing with 46 Italian provinces in year 1989. The results of regression analysis support the hypothesis that firms belonging to different size classes resort to different sources for the knowledge relevant to their innovative output. In particular, industry R&D prove to play a relatively more important function than do spillovers from university research in generating innovative output in large firms, whereas the opposite is true in the case of small firms.     

The Determinants of Pharmaceutical R&D Expenditures: Evidence from Japan

During the past 20 years, the world pharmaceutical industry has experienced a dramatic increase in R&D intensity. We apply and extend a model developed by Grabowski and Vernon (2000, Journal of Evolutionary Economics, 10, 201–215) with a pooled data sample of the 15 publicly listed Japanese drug firms for the period 1987–1998. As in the original study, we find expected returns to be an important determinant of R&D spending in the Japanese drug industry, albeit considerably smaller than in the U.S., which is particularly obvious in the case of returns from newly introduced drugs. However, our results are sensitive to econometric model specification, in particular to controlling for serial correlation and to a dynamic specification of the baseline model. Likewise, estimates on financial constraints are sensitive to model specification, indicating that Japanese drug firms face small or no financial constraints. Our results are consistent with the general literature on R&D investment behaviour, yet raise some methodological questions with regard to the original study.     

Research among copycats: R&D,spillovers, and feedback strategies

We study a stochastic dynamic game of process innovation in which firms can initiate and terminate R&D efforts and production at different times. We discern the impact of knowledge spillovers on the investments in existing markets, as well as on the likely structure of newly forming markets, for all possible asymmetries in production costs between firms. While an increase in spillovers may improve the likelihood of a competitive market, it may at the same time reduce the level to which a technology is developed. We show that the effects of spillovers on investments and surpluses crucially depend on the stage of technology development considered. In particular, we show that high spillovers are not necessarily pro-competitive as they can make it harder for the laggard to catch up with the technology leader.     

Competition in Research and Development: A Theory for Contradictory Predictions

This paper develops reasons for the many seemingly contradictory findings in the literature about competition and research and development (R&D) investment. The theory of R&D competition implies that increases in competitive pressure may increase R&D investment, decrease it, increase it initially but decrease it over greater levels of competitive pressure (an inverted-U relation), decrease it initially but increase it over greater levels (a U relation), or have no effect at all.      

Complementary assets,start-ups and incentives to innovate

We examine to what extent market conditions facilitating start-up formation affect firms' R&D investment and profits. We consider a model in which R&D efforts of an incumbent firm generate partly tacit technological know-how embodied in a key R&D employee, who might use it to form a start-up. The availability of complementary assets influences whether new firms are created and determine expected profits for start-up's founders. A large availability of complementary assets has the direct effect that the generation of start-ups is fostered. However, as a strategic effect, the incentives of incumbents to invest in R&D may be reduced because of the increased danger of knowledge loss occurring through start-up formation. We characterize the effects of an increase in the availability of complementary assets, showing that counter-intuitively there are cases in which it induces an increase in incumbents' R&D investment.     

Effects of R & D Spillovers on the Profitability of Firms

This cross-section study of a sample of 278 firms from the COMPUSTAT II database explores the relationship between a firm's profitability and other variables, notably its own R & D capital, knowledge and market spillovers and appropriability. The proxy for knowledge spillovers is based on technological distance. Market spillovers are based on a patent input-output matrix. Both spillover proxies combine information on R & D expenditures and patent counts.The results do not reject the hypothesis that R & D has a direct, positive effect on profitability, especially in industries with effective patent protection. Information spillovers affect profits negatively, market spillovers positively.     

Location advantages and subsidiaries’ R&;D activities in emerging economies: Exploring the effect of employee mobility

With multinational corporations increasingly seeking subsidiaries’ specific advantages in foreign countries to develop their innovative capabilities, internationalization of research and development has been greatly emphasized. However, in emerging economies, managers are encountering the challenge of high employee mobility under the weak intellectual property protection regime. This article investigates subsidiaries’ employee mobility and proposes that it negatively moderates the relationship between location advantages and the level of subsidiaries’ R&D. This article extends R&D internationalization and enhances current understanding of subsidiaries’ R&D activities. Further, it provides managerial implications as to how managers can improve R&D outcome by mitigating obstacles in emerging economies.

Creating relational rents: The effect of business groups on affiliated firms’ performance in Indonesia

This research attempts to extend the discussion of business groups in emerging economies by treating business groups as a form of interorganizational network that generates relational rents among affiliated firms by creating technological and managerial capabilities. Based on the relational view, this research investigates whether value created by business groups depends upon sharing, combining, and exchanging unique and specific resources or assets among affiliated firms. Results show that technological capabilities contribute to create relational rents in terms of affiliated firms’ investment in R&D and human capital. Managerial capabilities also contributed to generating relational rents through investment in managerial knowledge acquisition for affiliated firms without R&D units and in training for affiliated firms with R&D units. However, learning by exporting and learning from imported input do not yield relational rents within business groups. Overall, these findings reveal that business groups as interorganizational networks are contingent on their internal, unique, and specific capabilities, as social capital theory argues.
