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.

Relocation and investment in R&D by firms

The literature on foreign direct investment has analyzed corporate location decisions when firms invest in R&D to reduce production costs. Such firms may set up new plants in other developed countries while maintaining their domestic plants. In contrast, we here consider firms that close down their domestic operations and relocate to countries where wage costs are lower. Thus, we assume that firms may reduce their production costs by investing in R&D and likewise by moving their plants abroad. We show that these two mechanisms are complementary. When a firm relocates it invests more in R&D than when it does not change its location and, therefore, its production cost is lower in the first case. As a result, investment in R&D encourages firms to relocate.     

How effective are level-based R&D tax credits? Evidence from the Netherlands

This article examines the impact of the R&D fiscal incentive programme on R&D by Dutch firms. Taking a factor demand approach, we measure the elasticity of firm R&D capital accumulation to its user cost. Econometric models are estimated using a rich unbalanced panel of firm data covering the period 1996 to 2004 with firm specific R&D user costs varying with tax incentives. Using the estimated user cost elasticity, we perform a cost–benefit analysis of the R&D incentive programme. We find some evidence of additionality suggesting that the level based programme of R&D incentives in the Netherlands is effective in stimulating firms’ investment in R&D. However, the hypothesis of crowding out can be rejected only for small firms. The analysis also indicates that the level based nature of the fiscal incentive scheme leads to a substantial social deadweight loss.     

Wage‐Setting Institutions and R&D Collaboration Networks

We analyse how union structures that differ in the degree of wage‐setting centralisation affect the pattern of R&D network formation. Within the context of a three‐firm industry, a central union that sets a uniform wage is shown to induce a partial R&D network that includes two firms but excludes the third. In contrast, we find that, under less centralised union structures, firms have incentives to form R&D networks with a larger number of alliances. This result is consistent with the stylised facts for industrialised countries: recent decades have seen an upsurge in R&D alliances along with labour market deregulation towards more flexible wage‐setting institutions.     

Research and development and labour productivity: do high-tech firms exhibit labour- or capital-saving technical change?

Employment and output in the advanced technology sectors have generally exhibited above-average growth for more than two decades. While this industry accounts for a relatively small share of total employment, the majority of private sector research and development (R&D) expenditures in the US is concentrated within seven sub-sectors. However, little attention has been paid as to whether high-tech productivity exhibits Hicksian capital or labour ‘savings’ bias or tendency to displace either factor input over time. Biased technical change can occur as economies transition between growth regimes. An augmented production function is employed to analyse the additional impact of R&D activity on firm-level labour productivity. A panel data set comprised of high-tech firms located across the advanced economies, China and India from 1990 to 2013 is used in the analysis. Labour-saving technical change was present across the advanced technology sectors and most countries. The expanded models of labour productivity that used fixed effects with lagged regressors confirmed the prior results as well as finding that R&D per employee, relative R&D intensity and firm market share contribute to firm-level labour productivity growth across countries and sectors. Additional support was found for diminishing returns to scale but not for R&D spillover effects.     

R&D INVESTMENTS AND SEQUENTIAL WAGE NEGOTIATIONS*

This paper analyses how the structure of wage bargaining affects R&D investment by firms that increases the productivity of labour in a Cournot duopoly. We find that total expenditure on R&D is greater when wages are set simultaneously than when they are set sequentially. Thus sequential wage negotiations reduce the incentive for firms to innovate and affect the productivity of labour. When wage negotiations are sequential the productivity of labour is greater (lower) in the follower (leader) firm than when negotiations are simultaneous. We also obtain that for same parameter values it is possible for the firm with the lower productivity to end up paying a higher wage than the firm with the higher level of labour productivity.     

Product differentiation, process R&D, and the nature of market competition

We investigate the relationship between process and product R&D and compare the incentives for both types of R&D under different modes of market competition (Bertrand versus Cournot). It is shown that: (i) process R&D investments increase with the degree of product differentiation and firms invest more in product R&D when they can do process R&D than when they cannot; (ii) Bertrand firms have a stronger incentive for product R&D whereas Cournot firms invest more in process R&D; and (iii) cooperation in product R&D promotes both types of R&D relative to competition whereas cooperation in both types of R&D discourages R&D relative to cooperation in just product R&D.     

The struggle to survive in the R&D sector: Implications for innovation and growth

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.     

Strategic timing in R&D agreements

We study the endogenous formation of R&D agreements in a R&D/Cournot duopoly model with spillovers where also the timing of R&D investments is endogenous. This allows us to consider the incentives for firms to sign R&D agreements over time. It is shown that, when both R&D spillovers and investment costs are sufficiently low, firms may find difficult to maintain a stable agreement due to the strong incentive to invest noncooperatively as leaders. In this case, the stability of an agreement requires that the joint investment occurs at the initial stage, thus avoiding any delay. When spillovers are sufficiently high, the coordination of R&D efforts becomes a profitable option, although firms may also have an incentive to sequence noncooperatively their investment over time. Finally, when spillovers are asymmetric and knowledge mainly leaks from the leader to the follower, investing as follower may become extremely profitable, making R&D agreements hard to sustain unless firms strategically delay their joint investment in R&D.     

Capacity investment and green R&D in a dynamic oligopoly under the potential shift in environmental damage

We develop a differential oligopoly game to investigate firms’ capacity investment and green R&D efforts in the presence of the potential shift in environmental damage and under the spillover effect of R&D activities among firms. We find that when both the probability of potential shift in environmental damage and the efficacy of R&D activities are high, the spillover effect will discourage the R&D effort but encourage the capacity investment. Otherwise, the spillover effect will encourage the R&D effort but discourage the capacity investment. Moreover, the potential shift in environmental damage can significantly impact the capacity and green R&D decisions as well as the Pigouvian tax, especially in the case of a large number of firms, a high profitability of the product, a high level of interest rate, and a high level of R&D spillover among firms.     

Does foreign exchange derivatives market promote R&D? International industry-level evidence

Efficient financial markets can motivate and nurture innovation. The foreign exchange derivatives (FXD) market, an important part of financial markets, provides instruments to hedge profits from currency fluctuations. However, whether and how FXD market development benefits innovation remains unclear. Using data from a sample of 45 developed and emerging economies, this paper is among the first to examine the impact of the development of the FXD market on industry-level research and development (R&D) investment. We find that a better-developed FXD market significantly enhances industry-level R&D investment, especially in emerging economies. When the average daily FXD turnover that measures FXD market development increases by one standard deviation, industry-level R&D expenses increase by 27% in the following year. This effect is more significant for industries with higher foreign exchange rate risk. Policymakers should consider the benefits of developing the FXD market to the real economy when optimising FXD regulations.     

R&D and manufacturing production specialization in developed economies

A study of the relation between technology and manufacturing production specialization in a series of developed economies is performed by means of models relating indicators of revealed symmetric comparative advantage of value added and exports to similar measures of comparative performance of R&D expenditure, capital intensity, total factor productivity and wage costs. The production and R&D specialization are shown to be substantial and sticky. This contrasts with the evidence of a substantial degree of convergence in the patterns of the other variables. Regression estimates show that, although all variables play their part, the impact of comparative R&D efforts on production specialization is by far the strongest. This impact is found to be stronger in the smaller economies and it is especially important in research-intensive industries. The influence of comparative wages is, moreover, found to be positive here, suggesting the dominance of a labour skill and efficiency wage effect over a wage cost competitiveness effect. These findings are shown to conform quite well with the predictions of Schumpeterian theory and of certain contributions to ‘new trade theory’ that have stressed the importance of dynamic economies of scale.     

Trade and Technology from a Schumpeterian Perspective

This paper attempts to implement empirically a Schumpeterian model of international trade. After briefly discussing the literature on trade and technology, we formulate a model in which ‘real’ factors such as R&D expenditures, investment and wage costs have an impact on bilateral trade flows between advanced economies. We also take into account the effect of exchange rate differences. The model is empirically estimated on sectoral data for nine OECD countries. We find that what determines competitiveness differs by sector. In many sectors, either R&D expenditures or wage costs are important. The results for investment indicate a weaker role. Consistent with the Marshall-Lerner logic, we find that the sign of exchange rate changes varies by sector. We conclude the paper by a discussion of the relevance of the results for ‘technology-based’ theories of international trade.     

R&D spillovers and employment: evidence from European patent data

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.     

Costly investment, complementarities and the skill premium

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities between intermediate goods. We only find a positive relationship between the relative labour endowment and both the skill premium and economic growth within determined intervals of relative labour endowment values, which vary with the absolute productive advantage of high over low-skilled labour. The model thus accommodates theoretically mixed empirical results on the relative labour endowment-skill premium relationship. We further find that the impact on both the relative labour endowment and the skill premium of a rise in investment costs or in the complementarities degree depends on: (i) the absolute productivity advantage of high over low-skilled labour; and (ii) the relative labour endowment.     

R&D subsidies and private R&D expenditures: evidence from Italian manufacturing data

This paper uses a comprehensive firm level data set for the manufacturing sector in Italy to investigate the effect of government support on privately financed R&D expenditure. Estimates from a non‐parametric matching procedure suggest that public assistance has a positive effect on private R&D investment in the sense that the recipient firms achieve more private R&D than they would have without public support. This indicates that the possibility of perfect crowding out between private and public funds can be rejected. Furthermore, in this sample of Italian firms, tax incentives appear to be more effective than direct grants. The paper also examines whether public funding affects the financial sources available for R&D and finds that grants encourage the use of internal sources. The results also show some evidence of positive effects on credit financing for R&D.     

Innovation or imitation? The effect of spillovers and competitive pressure on firms’ R&D strategy choice

In this paper a firm’s R&D strategy is assumed to be endogenous and allowed to depend on both internal firm characteristics and external factors. Firms choose between two strategies, either they engage in R&D or abstain from own R&D and imitate the outcomes of innovators. This yields three types of equilibria, in which either all firms innovate, some firms innovate and others imitate, or no firm innovates. Firms’ equilibrium strategies crucially depend on external factors. We find that the efficiency of intellectual property rights protection positively affects firms’ incentives to engage in R&D, while excessive competitive pressure has a negative effect. In addition, smaller firms are found to be more likely to become imitators when the product is homogeneous and the level of spillovers is high. Regarding social welfare our results indicate that strengthening intellectual property protection can have an ambiguous effect. In markets characterized by a high rate of innovation a reduction of intellectual property rights protection can discourage innovative performance substantially. However, a reduction of patent protection can also increase social welfare because it may induce imitation. This indicates that policy issues such as the optimal length and breadth of patent protection cannot be resolved without taking into account specific market and firm characteristics.     

Firm value and the diversification choice: international evidence from global and industrial diversification

Our study examines the nature of industrial and global diversification for a sample of more than 12?000 firms across 35 emerging and developed countries during the period 1991–2006. Consistent with previous studies, we find that industrial diversification, either alone or combined with global diversification, results in a reduction of firm excess value. Global diversification alone, however, does not exert a significant impact on excess value. In an analysis of the decision to diversify, we find that firms in civil law countries or less developed nations are more likely to diversify, suggesting the greater utility of internal capital markets in economies where it is difficult to raise external capital. We observe that high leverage, larger size, lower levels of growth, R&D, free cash flow, profitability and Tobin's q encourage firms to diversify industrially. Higher values of q, firm size, R&D expenditures, free cash flow and liquidity, but reduced growth rates and profitability are associated with global diversification.     

Multimarket contact and inter-firm cooperation in R&D

Research joint ventures (RJVs) have been widely acclaimed for their alleged ability to restore private incentives to undertake R&D. Economists have, however, also sounded the alarm concerning the opportunities RJVs may create for collusion between partners. The danger of anti-competitive behavior increases significantly when repeated R&D collaboration occurs between firms that also “meet” in many product markets. This phenomenon is shown to be present in a large set of U.S.-based RJVs. The question is about the incentive trade-off: Are the alleged advantages of RJVs in terms of enhancing incentives for R&D sufficient to overcome the potential disadvantages in terms of decreasing incentives for R&D due to simultaneous multiproject and multimarket contact? Significant foreign participation, high technological and market uncertainties, and the set up of “porous” RJVs may operate as a check to anti-competitive behavior.     

Determinants of Chinese direct investments in the European Union

This article analyses the determinants of Chinese foreign direct investment (FDI) activities in the European Union (EU). Evidence is based on panel Poisson models drawing on two investment monitors at the individual project level. Greenfield investments (GI) and mergers and acquisitions (M&A) are distinguished. The findings indicate that market size and bilateral trade are the main factors for Chinese investment in the EU. In contrast, business-friendly institutions do not foster FDI. Probably, Chinese investors are risk averse, and prefer regions with less competitive markets. The striking difference between GIs and M&As is related to unit labour costs. Higher costs make the host country less attractive for the establishment of new firms, but do not affect the involvement in existing firms. The sectoral dispersion of Chinese FDI in the EU did not change much since the global financial crisis. Most relevant shifts have occurred in research and development (R&D), where low-income EU countries have become increasingly attractive.
