Strategic Rivalry With Spillovers Within Segmented Versus Integrated Markets

We consider a two-stage game with firms investing in R&D in the first stage while competing [a] la Cournot in the second stage. The firms are located in two countries, which are either segmented or integrated. R&D spillovers occur between firms located in the same country as well as between firms located in different countries.

We first examine the consequences of market integration on the impact of national and international R&D spillovers on innovative efforts, effective R&D, profits and total welfare. Comparing the resulting equilibrium levels, we subsequently conclude that market integration always leads to higher R&D investments and output if international R&D spillovers are limited, while the welfare consequences are ambiguous. Finally, we also analyze the welfare maximization problem of a ‘constrained social planner who can only decide on the level of R&D spillovers.     

ANTIDUMPING,INTRA‐INDUSTRY TRADE,AND QUALITY REVERSALS

We examine an export game where two (home and foreign) firms produce vertically differentiated products. The foreign firm is more R&D efficient and is based in a larger and richer market. The unique (risk‐dominant) Nash equilibrium exhibits intra‐industry trade, and the foreign producer manufactures a higher‐quality product. When transport costs are low, unilateral dumping by the foreign firm arises; otherwise, reciprocal dumping occurs. For some parameters, a domestic antidumping policy leads to a quality reversal in the international market whereby the home firm becomes the quality leader. This policy is desirable for the implementing country, though world welfare decreases.     

The effectiveness of R&D subsidies

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.     

Process R&;D and Product Line Deletion by a Multiproduct Monopolist

Relative to single-product firms, a multiproduct monopolist can internalize the negative externalities of its R&D investments (the ``cannibalization effect') in two ways: (1) To lower R&D investment for each product; and (2) To delete some of its product lines so as to enlarge the market size for the remaining lines. It is shown that line deletion is profitable if products are close substitutes. If products are not close substitutes, the multiproduct monopolist keeps all product lines and invests less in cost-reducing R&D than single-product firms engaging in Cournot competition with product differentiation. However, it invests more in R&D than single-product firms if there are significant economies of scope in R&D, or if the oligopolistic firms can cooperate in their R&D decisions.      

Research joint ventures in an international economy

D'Aspremont and Jacquemin's model is extended to study alternative configurations of research agreements in a two-country integrated world economy. Under unambiguous conditions on spillovers, we show that: (1) allowing national firms to cooperate in research and development (R&D) confers them an advantage over foreign rivals, an effect similar to R&D subsidies. (2) In a policy game, each government would allow national cooperative agreements. (3) Contrary to other trade policies which lead to a “prisoners' dilemma” result, welfare in both countries increases when they both allow R&D cooperation. (4) Welfare is even higher if a generalized (international) coalition is formed.     

The role of price and nonprice factors in predicting Australia's trade performance

This article investigates the role of price and nonprice factors in predicting Australia's trade performance. Results broadly suggest that Australia's trade performance is largely explained by the nonprice factors namely, R&D, reliability of domestic supply, aggregate world demand and Foreign Direct Investment (FDI) flows in long run. Price factors such as, relative price of Australian exports and domestic prices are also important predictors of trade competitiveness. The policy implications of these findings are that there are dividends in terms of improved trade performance by encouraging R&D expenditure, attracting FDI, improving domestic supply and implementing appropriate policies to improve price competitiveness.     

Innovation and international trade in technology

The international market for technology is growing rapidly relative to world GDP. To study the international technology market, I present a model of innovation and international trade in which inventors auction their technology in both domestic and foreign markets. There is monopolistic competition in differentiated products. International trade in technology has number of significant economic effects. Technology trade improves the quality of innovation by increasing the pool of R&D experiments from which the best technology is chosen. Technology trade increases the efficiency of invention while at the same time lowering the total number of inventors relative to the equilibrium without technology trade. Technology trade increases the volume of trade in goods. Technology trade increases product variety at the market equilibrium. Technology trade increases national income in each country and increases total gains from trade.     

R&D competition, absorptive capacity, and market shares

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.     

Competitiveness and R&D competition revisited

This paper formulates a duopoly model of firms concerned with relative profits as well as their own profits and investigates the relationship between the degree of competitiveness in a market and R&D expenditure. We find a non-monotone relationship between the two variables. When the duopoly market is not particularly competitive and when it is highly competitive, R&D activities are intensified. Thus, we are able to obtain similar results to both the pro-competitive and the Schumpeterian views in a single framework. We also discuss the welfare implications of changing competitiveness and consider cases of oligopoly and R&D cooperation as extensions to our basic model.     

Costs,knowledge and market structure: understanding the puzzle of international competitiveness with Greek export data

This is an analysis of the sources of international competitiveness with Greek export data for the period 1987–2007. The framework used in the study incorporates factors that do not only represent cost competitiveness but also shed light on the determinants of economic complexity. Economic complexity is the amount of knowledge capabilities embodied in exports that indicates – as a source of comparative advantage – the ability for product differentiation and product variety. The empirical analysis shows that industries benefit substantially from their own R&D activity but, owing to weak economic complexity in the country, there are no cross-industry knowledge spillovers (both at national and international level) that can benefit export activity. Greek exports were found to be sensitive to relative unit labour costs (RULC) but the most important export component of this index is relative labour productivity and not labour cost. Not all institutional arrangements have the same impact on exports, for example high trade union density might harm competitiveness but this factor is uncorrelated with R&D investment. In the view of these findings, Greece’s route to international competitiveness should be primarily by improving its economic complexity, making sure that the country specialises in productive activities that enrich its knowledge capabilities as well as increase the potential of knowledge transfer.     

R&D policy in a vertically related industry

In this paper, we analyze the effectiveness of public policy aimed to stimulate business-performed R&D in a vertically related market. We examine the role of an R&D active upstream supplier in a four-stage R&D model, where we incorporate public funding. The considered policy instrument is direct funding of firms’ R&D efforts. We calculate the optimal policies and show that they have a positive impact on firms’ R&D investments. From a welfare point of view, it is optimal to differentiate the subsidy rates between the upstream and the downstream markets. Competition in the product market leads to a higher subsidy rate to the upstream supplier than to the downstream firms. When concentration is high in the downstream market, the optimal solution is an R&D subsidy for these firms, otherwise the optimal solution is an R&D tax for the downstream firms.     

International Cooperation on Climate-friendly Technologies

We examine international cooperation on technological development as an alternative to international cooperation on emission reductions. We show that without any R&D cooperation, R&D in each country should be increased beyond the non-cooperative level if (i) the technology level in one country is positively affected by R&D in other countries, (ii) the domestic carbon tax is lower than the Pigovian level, or (iii) the domestic carbon tax is set directly through an international tax agreement. We also show that a second-best technology agreement has higher R&D, higher emissions, or both compared with the first-best-outcome. The second-best subsidy always exceeds the subsidy under no international R&D cooperation. Further, when the price of carbon is the same in the second-best technology agreement and in the case without R&D cooperation, welfare is highest, R&D is highest and emissions are lowest in the second-best R&D agreement.     

Does R&D spending boost tangible investment? An analysis on European firms

This article investigates the relationship between firm’s R&D intensity, expressed as R&D expenditure over sales, and investment intensity in tangible assets. It is commonly acknowledged that R&D requires additional physical investment to be implemented. R&D increases a firm’s productivity and return to tangible investments, thus, providing to the firm incentives to bear high tangible capital costs and to invest more. This represents a crucial issue for a firm’s growth, particularly considering the strong interaction between physical capital accumulation and technological progress. The analysis is based on a large sample of manufacturing firms across seven European countries in the period 2007–2009. Since the sub-sample of firms performing R&D might not be random, there may potentially be an endogeneity issue. The analysis also considers that firms may decide to spend on R&D and investment in physical capital simultaneously. The questions of both endogeneity and simultaneity are dealt with by employing an instrumental variable two-step procedure. We find a positive and significant impact of R&D intensity on firms’ tangible investment intensity. The econometric results highlight the importance of financial factors, particularly with respect to firms’ internal resources. Exposure to international trade has a negative impact on investment, possibly depending on the time-span of the sample used.

International R&D Collaboration and Strategic Trade Policy

We study an international trade model with symmetric countries and symmetric firms, with countries making strategic trade policies, anticipating the decisions of firms on R&D collaboration at the subsequent stage. In general we should observe a conflict between the equilibrium outcome and the efficient one. We find that an asymmetric outcome where one country unilaterally liberalizes trade while the other does not is likely to occur. We also find that while banning international R&D collaboration may help to reach free trade equilibrium in certain situations, it provides little assistance in reaching the outcome that maximizes global welfare.     

R&D investment and internal finance: the cash flow effect

This paper investigates the cash flow effect on R&D investments for firms in Denmark. Evidence is found that internal funds are important in explaining R&D investments, indicating that R&D investment decisions are affected by credit market imperfections. Cash flow sensitivities are larger both for smaller firms and for firms with low debt relative to assets. Furthermore, this effect is also present after controlling for cash flow’s potential role as a predictor of future profitability.     

Dynamic R&D choice and the impact of the firm's financial strength

ABSTRACT

This article investigates how a firm's financial strength affects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German firms in high-tech manufacturing industries. The model incorporates a measure of the firm's financial strength, derived from its credit rating, which is shown to lead to substantial differences in estimates of the costs and expected long-run benefits from R&D investment. Financially strong firms have a higher probability of generating innovations from their R&D investment, and the innovations have a larger impact on productivity and profits. Averaging across all firms, the long-run benefit of investing in R&D equals 6.6% of firm value. It ranges from 11.6% for firms in a strong financial position to 2.3% for firms in a weaker financial position.     

Multinationals,R&D and Endogenous Productivity Asymmetries

We analyze the influence of endogenous productivity asymmetries between firms, in terms of competitiveness and size, on multinational activity. In the model, productivity depends on cost-reducing R&D (research and development). We show that when firms differ on commitment power in R&D, the R&D leader, independently of being a multinational or a domestic firm, tends to invest more in R&D than the R&D follower. Because of these productivity advantages, the R&D leader can more easily become multinational. Therefore, in addition to the proximity-concentration trade-off, we identify another FDI (foreign direct investment) determinant: technological competition.     

Strategic R&D policy under multiproduct duopoly and quality-price competition

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.     

Employment growth and innovation at the firm level

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.     

Trade,labour market rigidity,and aggregate productivity in OECD countries

As the economy becomes more open to trade, aggregate productivity can increase by driving out the least productive firms (the selection effect). Since the selection effect reallocates resources toward the more productive firms, this process can be hindered by rigidity in domestic labour market institutions. Based on the selection effect by Melitz (2003), this article empirically examines how rigidity in labour market institutions affects the consequence of trade on aggregate productivity. Findings from panel dynamic ordinary least square (DOLS) estimators suggest that a high degree of labour market rigidity in an open economy reduces Total Factor Productivity (TFP). In particular, in the case of extremely high labour market rigidity but low foreign R&D capital stocks, openness to trade can cause a country to experience decreasing TFP.
