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.     

In-house R&D,external R&D and cooperation breadth in Spanish manufacturing firms: is there a synergistic effect on innovation outputs?

ABSTRACT

This study explores the nature of relationship between in-house R&D, external R&D and cooperation breadth and their joint impact on patent counts as well as technological, product and process, innovations in Spanish manufacturing firms. With regards to patent counts, empirical findings from a Generalized Method of Moments (GMM) estimator suggest a complementarity effect of internal and external R&D activities conditional on the breadth of R&D cooperation. Concerning technological innovation, results from dynamic random-effects probit models indicate no synergistic effects. In addition, we find evidence of persistence of all three innovation output measures. Our results suggest policy implications in relation to strengthening firms’ absorptive capacity that could have long-run effects.     

R&D and patents: is it a two way street?

ABSTRACT

This paper provides empirical evidence on the link between firms’ R&D expenditure and patent registrations by applying the Granger causality test. We use a panel of Spanish manufacturing firms for the period 1990–2013. We first, examine the R&D-patents relationship in the manufacturing firms as a whole and subsequently, manufacturing was broken down into three groups of firms according to the technological level of the industries to which the firms belonged: high and medium-high (HMHT), low medium (LMT) and low (LT) technology firms. For the entire panel, our results provide support for a bidirectional relationship between R&D and patents, supporting both the traditional view and the reverse causality approach (patents cause R&D). When the sample is split into the three technology levels, we also find strong support for a bidirectional relationship in HMHT firms and weak support in LT ones. We found no evidence of this bidirectional link in LMT firms.     

Foreign direct investment in R&D and domestic entrepreneurship in China’s manufacturing industries

This paper argues that internationalization of innovation and the related spillovers can also affect the likelihood of firm entry and exit into an industry. By making use of firm-level panel data from China over the period 2005 to 2007, this paper examines the impact of foreign direct investment (FDI) in research and development (R&D) and the related linkages on entry and exit likelihoods of domestic firms in (i) transport equipment and (ii) electrical machinery and equipment manufacturing industries. In order to evaluate the region-of-origin effect, this paper also separately examines the impact of FDI in R&D originating from (i) all countries except Hong Kong, Macau and Taiwan and (ii) Hong Kong, Macau and Taiwan. Furthermore, the impact of FDI in R&D on entry and exit of Chinese firms in the two industries is examined by splitting the data into large and small firms within the two industries. The results of the pooled probit regression reveal that FDI in R&D and the related spillovers can have a significant impact on the likelihood of entry and exit of domestic firms in transport equipment and electric machinery and equipment industries. The empirical analysis also suggests that the impact of changes in FDI in R&D and the related spillovers varies across firm size.     

Does issuing equity help R&D activity? Evidence from unlisted Italian high-tech manufacturing firms

This paper evaluates the causal effect of issuing equities on the probability that a firm engages in R&D activity. Equity is a better source of external finance than debt for innovation. It does not require collateral, does not exacerbate moral hazard problems connected with the substitution of high-risk for low-risk projects, quite common when using debt, and, unlike debt, does not increase the probability of bankruptcy; equity also allows investors to reap the entire benefit of the returns of successful innovative projects. This paper focuses on high-tech firms for which asymmetric information problems are more pervasive. Implementing an instrumental variable estimation, we find that issuing equity increases the probability that the firm has R&D expenditures by 30–40%. We detect considerable heterogeneity in this effect: the impact of issuing equity is significant only for small, young and more highly leveraged high-tech firms. We also find interesting evidence that issuing equity increases R&D expenditures in relation to sales.     

Efficiency and productivity in the Indian unorganized manufacturing sector: did reforms matter?

This paper analyzes total factor productivity growth of the unorganized manufacturing sector in India using several rounds of the large scale national sample survey state level data for 15 major Indian states for the period 1978–1979 to 2000–2001. Data envelopment analysis is used to compute Malmquist total factor productivity index and its components. The impact of economic reforms on efficiency and productivity is examined. Evidence suggests that total factor productivity registered a positive growth during the period in the country as a whole. Most states in the country witnessed higher total factor productivity growth in the post 1990s reforms period than in the pre-reforms period. Decomposition of the Malmquist productivity index shows that improvement in technical efficiency rather than technical progress had contributed to the observed acceleration in the growth rate. Econometric analysis of the determinants of total factor productivity growth demonstrates that ownership, literacy, farm growth and infrastructure availability significantly influence total factor productivity growth in the sector.

Is export diversification good for profitability? First evidence for manufacturing enterprises in Germany

This article uses a tailor-made newly available data set for enterprises from manufacturing industries in Germany to investigate for the first time the links between export diversification over destination countries and goods on the one hand and the profitability of the exporting firms on the other hand. We find that profits tend to be larger in firms with less diversified export sales over goods and in firms with more diversified export sales over destination countries.     

On the Time‐Varying Relationship between Unemployment and Output: What shapes it?

This paper revisits, by means of both time series and panel data analyses, the empirical regularity popularized by Okun's (Proc Bus Econ Sect, 98‐103, 1962) seminal paper focusing on a sample of 20 advanced economies between 1978 and 2015. Not only do we provide arguably better estimates of the Okun's Law coefficient (OLC) (using the gap version) by employing a new filtering technique, but more importantly, we also contest the hypothesis that the OLC has been static over time. By estimating country‐specific time‐varying Okun coefficient models, we confirm that the unemployment‐output responsiveness has been changing over time. The dispersion between countries’ OLCs has been determined by some (structural) characteristics. The starting level of unemployment and the phase of the business cycle increase the estimated OLCs, while informality and certain labour and product market policies lower them. Our evidence sustains the fact that aggregate demand policies aiming at increasing output growth can equally contribute to the recovery in labour markets.     

Metaphors for manufacturing: What could it be like to be a manufacturing system?

In the world of modern manufacturing, considerable emphasis is placed upon properties of manufacturing systems described by the terms “flexibility,” “complexity,” “reliability,” “self-repairing,” and so forth. To understand and deal with such properties, one needs a theoretical framework allowing one to pose and analyze various questions surrounding the meaning and interrelations of these terms. This paper addresses the questions of what sort of system-theoretic frameworks would be likely candidates to form the basis for such a theory of manufacturing.Our approach to the modeling problem is to examine several different paradigms that have proven useful in other fields—engineering, biology, linguistics, computer science, chemistry—and to explore the degree to which these “metaphors” can be used to characterize manufacturing systems. The paper concludes with an assessment of the strengths and weaknesses of each metaphor and a suggestion for a program devoted to further development of the most promising approaches.     

Intellectual property rights and R&D subsidies: are they complementary policies?

IPR protection and R&D subsidy are simultaneously implemented in many economies. Are they complementary policies for improving the welfare of consumers? We address this question in a dynamic general equilibrium model with innovation-driven growth. Under concave utility, the answer is yes for two cases: (1) the economy does not begin from steady state and the elasticity of intertemporal substitution (EIS) is relatively large; (2) the economy begins from steady state with either a sufficiently small initial consumption and a relatively large EIS or a sufficiently big initial consumption and a relatively small EIS. Under linear utility, the answer is yes if the discounted lifetime utility is finite in equilibrium, no matter the economy begins from the steady state or not. As empirical evidence finds cross-country heterogeneity in EIS, they are not complementary for all economies. We also identify reasonable cases whereby they are substitute policies, so we show when it is not welfare-enhancing to simultaneously implement both policies.     

Does R&D,human capital and FDI matter for TFP in OECD countries?

ABSTRACT

This study investigates the interplay between research and development (R&D), human capital (HC), foreign direct investment (FDI) and total factor productivity (TFP) in OECD countries. We divide the sample into two sub-groups; the European and the non-European states so as to account for underlying country heterogeneity. The analysis follows a panel data approach over the period 1995–2015, taking into account the modelling on non-stationarity, long-run relationships and short-run dynamics with a panel VAR. Both R&D and HC have a positive effect on TFP, whilst FDI has a positive and significant effect only in the case of non-European countries. Moreover, the contribution of R&D is higher than that of HC and FDI in all cases. Thus, based on these findings, policymakers should design and implement policies to increase resources invested in R&D, with a consistent ongoing spending review, to attract foreign direct investment, especially for the majority of the European and some of the non-European countries and to improve education system on a more productive innovation and research base.     

R&D expenditures and firm growth – is small beautiful?

ABSTRACT

This paper examines how efficiently different groups of firms use their R&D expenditures. To this end, it investigates how the empirical relationship between firms' R&D expenditures and their sales growth varies with different values of firm size, firm age, and the number of firms in the respective industry. Using panel data for Switzerland ranging from 1995 to 2012, the paper finds that smaller, more mature firms show a more positive relation between R&D expenditures and sales growth than both relatively larger or younger firms. The paper argues that, on the one hand, these firms can benefit from various small size advantages in the R&D process, such as more motivated researchers, caused by a stronger connection to the firm's fate. On the other hand, these firms can also benefit from a well-established R&D department that allows absorbing the latest technological developments. The paper further finds that industries consisting of many small firms show a more positive relation between R&D expenditures and sales growth than industries consisting of only a few large firms. The intuition behind this result is that industries consisting of many small firms imply more independent innovative trials, which then together result in a higher probability of discovering successful innovations. In sum, the paper finds that groups consisting of a large number of small, more mature firms spend their R&D in the most efficient way.

Is Embodied Technology the Result of Upstream R&D? Industry-Level Evidence

This paper provides an exploratory analysis of whether data on the research and development (R&D) spending directed at particular technological/product fields can be used to measure industry-level capital-embodied technological change. Evidence from the patent literature suggests that the R&D directed at a product, as the main input into the “innovation” production function, is proportional to the value of the innovations in that product. I confirm this hypothesis by showing that the decline in the relative price of a good is positively correlated with the R&D directed at that product. The hypothesis implies that the technological change, or innovation, embodied in an industry's capital is proportional to the R&D that is done (“upstream”) by the economy as a whole on each of the capital goods that a (“downstream”) industry purchases. Using R&D data from the National Science Foundation, I construct measures of capital-embodied R&D. I find they have a strong effect on conventionally measured total-factor productivity growth, a phenomenon that seems to be due partly to the mismeasurement of quality change in the capital stock and partly to a positive correlation between embodied and disembodied technological change. Finally, I find the cross-industry variation in empirical estimates of embodied technological change accord with the cross-industry variation in embodied R&D.

Reverse causality in the R&D–patents relationship: an interpretation of the innovation persistence

Starting from the failure of the R&D–patents traditional relationship, when time-series and/or within-industry dimensions are included in the empirical analysis, the present work tries to contribute to the empirical literature from two directions. First, it performs a Granger causality test based on the theoretical presumption of a reverse patents→R&D link as an explanation for the failure of the traditional relationship. Second, assuming the reverse patents–R&D causality, we test and interpret the lag structure of such a relationship which shows the effective patent life that firms can expect within the two Schumpeterian patterns of innovations they belong to. In the light of the effective patent life, we offer a further explanation of innovation persistence which overturns the findings of the existing literature on persistence.
