Unsuccessful patent application and cooperative R&;D

We show that uncertainty in patent approvals may induce the firms to do cooperative R&D. With an exogenous probability of success in patent application, we show that, if all firms apply for patents under non-cooperative R&D, the firms prefer cooperative R&D than non-cooperative R&D for moderate (high) probabilities of success in patent applications, if the cost of patenting is small (large). We also show the implications of entry of non-innovating firms and endogenous probability of success in patent applications.      

Strategic Product R&D Investment Policy under International Rivalry in the Presence of Demand Spillover Effects

Abstract

We develop a model of product (i.e., quality-improving) research and development (R&D) investment competition in a horizontally differentiated duopoly. In particular, based on a third-country market model, we consider the optimal product R&D investment policy under international rivalry in the presence of demand spillover effects associated with improving the quality level of a product. We show how the optimality of a non-cooperative and a cooperative R&D investment policy depends on the strength of demand spillover effects. Furthermore, we consider the same issues in the case of heterogeneous consumers and alternative utility functions.     

Cooperative R&D and Commitment to A Policy of Know-how Trading

In this paper, we develop a theoretical framework to investigate the impact of adopting a strategy of know-how trading on the degree of research and development (R&D) cooperation. We show that the consequences of cooperation in know-how sharing under the conditions of the model are similar to a policy of cooperation in R&D investments in areas with large spillovers. An industry-wide policy of cooperation among competitors with respect to R&D investment and sharing would simply result in maximal joint profits. This cooperative R&D outcome could be generalized to any degree of spillover other than 100%. In this paper, the commitment to a policy of know-how trading by the participants in an industry is explained by the firm’s attempt to induce the equilibrium of a single industry-wide cooperative research joint venture. In a repeated game framework, we show that pre-commitments by non-cooperative firms to disclose their own know-how to the industry can be effective in inducing cooperative R&D investments by the participants.     

Can a larger market foster R&D under monopolistic competition with variable mark-ups?

We study monopolistic competition with symmetric directly additive preferences (generating variable mark-ups) and an endogenous technology choice. Each firm chooses an investment in R&D to decrease its marginal cost. We prove that the equilibrium R&D investment increases with market size (a larger population or trade) only if the price-elasticity of demand is an increasing function. Together with the output levels, such equilibrium investments may be socially excessive or insufficient, depending on whether the elasticity of the subutility is increasing or decreasing. The main implication is that opening up to free trade can foster R&D through variable mark-ups.     

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.      

On the incentives for cooperative research

This paper analyzes incentives for cooperative research for firms competing in the product market. Contrary to the literature, we portray situations to show that non-cooperative R&D can occur even if the probability of success in R&D is large. We then model synergy in cooperative R&D and show that when the innovation size is large, cooperative research is likely to occur.     

Matching public support for private product-innovating R&D: a theoretical analysis

This paper develops a theoretical model of product innovation where research and development (R&D) effort by a monopolist firm is endogenous and its outcome uncertain. The government attempts to aid such efforts with a matching grant. We consider different scenarios depending on whether two parties act simultaneously, act sequentially, or take part in a dynamic cooperative game with a trigger strategy. We also consider cases (i) when the products are exported, (ii) when the firm lobbies for R&D subsidy, and (iii) when the firm is foreign owned. We characterize situations when government intervention increases the chances of product innovation and when it does not.     

To what extent do earnings affect the R&D decision of Chinese manufacturing firms?

ABSTRACT

As R&D activities are involved in inherent uncertainty of large investment, high risk and long return periods, earnings, as the main source of internal financing, have been a significant factor of R&D decision in the firms. In contrast to the previous research, this study investigates the impacts of firm’s earnings on R&D decision, in which earnings are measured by the indicators of earnings level, earnings quality and earnings persistence, while separating firm R&D activity into two stages of (i) the decision to undertake R&D activity and (ii) the amount to be invested on innovation activities. We document that earnings level can increase the probability of undertaking R&D activity, but has no effect on R&D investment intensity. Earnings quality and earnings persistence have a promotional effect on both stages of R&D decision. The empirical evidence of the subsamples shows that the impacts of earnings are heterogeneous across different ownership and technology-intensity firms.     

Market structure and R&D investment spillovers

This paper examines research and development (R&D) investment spillovers across different market structures. In particular, we extend the recent work in Matsumura et al. (2013) to incorporate R&D investment spillovers. When the market is a duopoly, noncooperative (cooperative) R&D investment is preferred for small (large) spillovers of less (more) than half. We show that as a market structure becomes more competitive, noncooperative R&D investment is more likely to be preferred. Moreover, noncooperative R&D is not always decreasing with the intensity of competition, even though it is ultimately zero with perfect competition. Our theoretical results fit well with existing empirical findings.     

Cooperation or competition in R&D when innovation and absorption are costly

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.     

Effect Of Liquidity On Firms' R&D Spending

The effect of firms financial condition on their R&D investment is explored using a relatively long panel data set for five high-technology industries. We find that financial condition, whether measured as cash flow, the stock of liquid assets or the ratio of liquid assets to current liabilities, does affect the R&D spending of small firms. The effect persists after controlling for unobserved permanent firm effects, and the pattern of significance of lagged effects supports the interpretation of causality running from liquidity to R&D. For larger firms, there is no evidence of such an effect. Using these data, we cannot say whether the absence of an effect in larger firms results from better access to capital markets or from higher adjustment costs in R&D.     

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.     

Noncooperative versus cooperative R&D with endogenous spillover rates

This paper deals with a general version of a two-stage model of R&D and product market competition. We provide a thorough generalization of previous results on the comparative performance of noncooperative and cooperative R&D, dispensing in particular with ex-post firm symmetry and linear demand assumptions. We also characterize the structure of profit-maximizing R&D cartels where firms competing in a product market jointly decide R&D expenditure, as well as internal spillover, levels. We establish the firms would essentially always prefer extremal spillovers, and within the context of a standard specification, derive conditions for the optimality of minimal spillover.     

Pollution abatement with disruptive R&D investment

This paper examines a model of investment in abatement where polluting firms produce output while investing in R&D. This investment, however, increases production costs, thus disrupting first-period output. We identify three equilibrium profiles where firms choose to either: (1) invest in R&D alone (thus rationalizing a common modeling assumption in the literature); (2) produce output alone; or (3) engage in both activities. We evaluate how the emergence of each result is affected by the market structure in which firms compete and by the severity of spillover effects. We then measure welfare levels in each equilibrium profile. Overall, we show that firms endogenously choose to focus on R&D only when the market is concentrated and spillover effects are small. In other type of industries, our findings indicate that firms may focus on output production or engage in both activities under relatively large conditions.     

STRATEGIC R&D AND NETWORK COMPATIBILITY

We analyse the effects of network externalities in strategic R&D competition. We present a model of two firms competing with R&D investments and prices in a differentiated consumer market. Buyers form firm-specific networks which can be compatible. A high degree of compatibility and large spillovers moderate price competition due to weak strategic value of firm-specific networks and R&D investments, respectively. Asymmetry in product qualities brings out network effects that cancel out in conventional symmetric settings. The lower quality firm increases R&D and decreases its price as spillovers or network compatibility is increased. This happens when R&D and firm-specific network size have high strategic value.     

Firm Metrics with Continuous R&;D,Quality Improvement,and Cournot Quantities

The paper considers a dynamic two-firm model of intra-industry trade in which the firms compete for the same market on the basis of product reliability. By assumption, the home firm always has the reliability cost advantage but it may or may not have the manufacturing cost advantage. The results suggest that reliability improvement always helps customers in that they pay a lower full quality price. Comparing the home firm with the foreign firm, metrics such as price, sales, profit margins, and variable profits depend on the relative costs, with the low cost firm performing better. Finally, although this is not the common outcome, the paper suggests that it is possible for the reliability cost advantages gained by R&D expenditures to overcome manufacturing cost disadvantages.     

Effects of coordinated strategies on product and process R&;D

Using a game theoretical model on firms’ simultaneous investments in product and process R&D, we advance and empirically test hypotheses on the role of externalities on the optimal R&D portfolio of cooperating firms and independently competing firms. We use Community Innovation Survey data on 3,696 Italian manufacturing firms. In line with our model we find that members of a group of firms invest significantly more into product, process, and aggregate R&D than independent firms. Further, their R&D portfolios tend to show a higher product versus process ratio. However, with regard to R&D performance and efficiency we find that independent firms are superior.      

R&;D: A Small Contribution to Productivity Growth

In this article I evaluate the contribution of R&D investments to productivity growth. The basis for the analysis are the free entry condition and the fact that most R&D innovations are embodied. Free entry yields a relationship between the resources devoted to R&D and the growth rate of technology. Since innovators are small, this relationship is not directly affected by the size of R&D externalities, or the presence of aggregate diminishing returns in R&D after controlling for the growth rate of output and the interest rate. The embodiment of R&D-driven innovations bounds the size of the production externalities. The resulting contribution of R&D to productivity growth in the US is smaller than 3–5 tenths of 1% point. This constitutes an upper bound for the case where innovators internalize the consequences of their R&D investments on the cost of conducting future innovations. From a normative perspective, this analysis implies that, if the innovation technology takes the form assumed in the literature, the actual US R&D intensity may be the socially optimal.     

Evidence on the impact of R&D and ICT investments on innovation and productivity in Italian firms

Both research and development (R&D) and information and communication technology (ICT) investment have been identified as sources of relative innovation underperformance in Europe vis-à-vis the USA. In this article, we investigate the R&D and ICT investment at the firm level in an effort to assess their relative importance and to what extent they are complements or substitutes. We use data on a large unbalanced panel data sample of Italian manufacturing firms constructed from four consecutive waves of a survey of manufacturing firms, to estimate a version of the CDM model of R&D, innovation, and productivity [Crépon–Duguet–Mairesse 1998. Research, innovation and productivity: An econometric analysis at the firm level. Economics of Innovation and New Technology 7, no. 2: 115–58] that has been modified to include ICT investment and R&D as the two main inputs into innovation and productivity. We find that R&D and ICT are both strongly associated with innovation and productivity, with R&D being more important for innovation, and ICT investment being more important for productivity. For the median firm, rates of return to both investments are so high that they suggest considerably underinvestment in both these activities. We explore the possible complementarity between R&D and ICT in innovation and production, but find none, although we do find complementarity between R&D and worker skill in innovation.     

A simple theory and evidence on the determinants of firm R&D

This paper derives a simple, but informative, model of firm R&D to figure out key factors that determine firm R&D effort. The model suggests a demand-pull, technology-push theory of R&D by showing that a firm's profit-maximizing R&D expenditure is determined jointly by both demand-side factors and technology-side factors. The former includes demand size (firm sales) and consumer preference over quality and price and the latter includes R&D cost structure or the production-cost effect of product R&D and firm-specific technological competence. In addition, the model shows that other things being equal, the stock of exogenous technological knowledge, including the firm's previously accumulated technological knowledge, relevant to current R&D which is negatively related with current R&D effort. An empirical analysis of firm R&D intensities and technological capabilities of more than 1600 firms in nine industries across six countries provides supportive evidence for the theory. Further, the theory implies that R&D intensity or the R&D-to-sales ratio is independent of firm size unless firm size affects technological competence and that given consumer preference and R&D cost structure facing all firms in the same industry, the distribution of firm-specific technological competence among firms determines the distribution of firm R&D intensities within the industry.
