Human capital and firms’ innovation: evidence from emerging economies

ABSTRACT

We explore the relationship between human capital and firms’ innovation in emerging economies. Most papers consider the formal knowledge developed in R&D laboratories as a major source of innovation. However, a critical portion of knowledge required for innovation resides in human resources and is created outside any formalised R&D activity. We consider that, to improve their technological capabilities, firms should invest in different forms of human capital, namely highly educated workforce and experienced managers, but also in strategic human resource (HR) practices aimed at developing human capital by increasing employees’ firm-specific technical skills and competences. Besides looking at the type of innovation outcomes, we place greater emphasis on the strategies of innovation development, as these should signal an improved firms’ ability, not just to innovate, but to put their own creative effort in the development of innovation. Our results contrast with the traditional view of firms in emerging economies as mainly relying on the external acquisition of innovations, by showing their actual ability to develop new technologies. In this respect, HR practices aimed at fostering employees’ learning and autonomy at work appear more important than the educational attainment of workers, whilst the experience of managers does not seem effective.     

How do housing cycles influence listed firms’ R&D investment: evidence from the collateral channel

ABSTRACT

Firm innovation is essential to long-run economic growth. Financially constrained R&D firms may use firm-owned properties as collateral to finance their R&D projects. Therefore, the housing price cycle can affect firms’ R&D investment through influencing their real estate value. By examining listed R&D firms during the housing boom period 2002–2006 in the U.S., we find that a $1 increase in real estate value leads a firm to increase its R&D investment by $0.38. We also find that this collateral effect is more pronounced among financially constrained R&D firms than that among unconstrained ones. Additionally, we examine the housing bust period 2008–2012, and find that real estate depreciation retarded R&D investment, especially among constrained R&D firms.     

Board of directors’ quality and firms’ debt financing: the moderating effect of insider ownership – evidence from Omani firms

This study aims to examine the direct effects of board of directors’ quality and insider ownership on firms’ capital structure and the moderating effect of insider ownership on the relationship between board of directors’ quality and firms’ capital structure. The sample of this study consists of the time period 2005–2011. The final sample consists of 535 firm-year observations of public nonfinancial firms listed on the Muscat Securities Market (MSM). The hypotheses are tested using a random effects model. The results reveal that the coefficient sign on the board of directors’ quality is as predicted, but the coefficient sign is insignificant. Further, the results show that insider ownership is positively associated with leverage at the significant level of 10%, suggesting that the inside substantial shareholders employ higher leverage. With regard to the moderating effect of insider ownership, the findings show that the effect of the board of directors’ quality-leverage relationship becomes negative and stronger with increasing insider ownership.     

How open search strategies align with firms’ radical and incremental innovation: evidence from China

The purpose of this paper is to describe the ways in which open search strategies (i.e. open search breadth and open search depth) align with firms’ radical and incremental innovation. By analysing survey data collected from 162 firms in Chinese high-tech markets, we found that a firm pursuing radical innovation benefits more from open search breadth than open search depth to achieve its performance goals; in contrast, a firm processing incremental innovation benefits more from open search depth than open search breadth to improve its performance. Based on these results, managers should pay attention to the fit between open search strategies and radical/incremental innovation. This study not only contributes to the studies of search strategies by identifying the parallel relationship of open search strategies and two types of innovation, but also enriches the theory of open innovation with an empirical analysis.     

Patterns and determinants of skilled workers’ mobility: evidence from a survey of Italian inventors

Skilled workers’ mobility is considered to be one of the most influential channels of knowledge transmission. This has increased the interest of researchers and policy makers because of its implications for innovation diffusion and, consequently, economic welfare. However, little is still known about the determinants of this phenomenon.

This paper explores the mobility patterns for a group of Italian inventors in the pharmaceutical sector. It addresses methodological issues related to measures of inventors’ mobility through patent statistics and examines the determinants of their mobility choices.

The empirical results indicate that career paths of inventors are rarely reflected in their patenting activity and that using patent statistics frequently underestimates the intensity of the mobility phenomenon. The results also show a positive association between productivity and mobility. In particular, the econometric analysis points out that inventor's personal characteristics, inventive productivity, and geographical location matter for mobility choices.     

Agglomeration economies and clustering – evidence from German and European firms

This article empirically analyses the impact of agglomeration economies on the clustering of German and European firms using partial proportional-odds models. Firms are grouped according to industry and divided into departments. At the industry level, I find evidence for inter-industry economies derived from the New Economic Geography (NEG) framework for European firms in general and German knowledge-intensive firms in particular. At the department level, Marshallian Externalities such as the hiring of skilled labour and technological spillover, and therefore intra-industry economies, are empirically confirmed for European and German departments like Human Resources and R&D but rarely for others.     

Bank distress and firms’ investment during the Great Recession - evidence from Ireland

This article investigates the impact of bank distress on firms’ performance using unique data during the Great Recession for Ireland. The results show that bank distress, measured as banks’ credit default swap spreads (CDS), has negatively and statistically significantly affected firms’ investment expenditures. Interestingly, firms with access to alternative sources of external finance are not impacted by bank distress. The results are robust to accounting for external finance dependence, demand and trade sensitivities, which affect firm performance and the demand for credit.     

How does FDI affect domestic firms’ wages? theory and evidence from Vietnam

This paper explores the role of inward foreign direct investment (FDI) as a determinant of domestic firms’ wages, namely wage spillovers. We first construct a theoretical model to demonstrate that the presence of FDI firms affects domestic firms’ expected average wages via productivity spillovers and a cut-off capability. We then estimate FDI-induced wage spillovers by employing IV-GMM estimator with a five-year panel dataset of a growing service industry in Vietnam. Despite FDI firms on average pay 2.25 times that of domestic firms, they put a downward pressure on domestic firms’ wages. A one percent increase in FDI presence causes domestic firms to cut average wages by 2.03 percent. The estimations also find that firm-specific features are attributable to significant differences in their wages as well as FDI-linked wage spillovers.     

The impact of science and technology parks on firms’ product innovation: empirical evidence from Spain

Science and Technology Parks (STP) have attracted considerable attention and public funds in recent years. However, the conclusions on their effectiveness remain mixed. This work evaluates the impact of STP on firm product innovation in the Spanish context, as an example of a less developed innovation system in which regional and national governments are prioritizing STP initiatives. This work draws on a large sample of firms provided by the Spanish Survey on Technological Innovation that is conducted annually by the National Statistical Institute. We explore alternative econometric methods to obtain average treatment effects for firms located in 22 Spanish STPs. Our results show that Spanish STPs have a strong and positive impact on the probability and amount of product innovation achieved by STP located firms. These results hold when the endogeneity of STP location is taken into account.     

Home-country environment and firms’ outward foreign direct investment decision: Evidence from Chinese firms

This paper takes a holistic view and examines the environmental effect of the home country on firms’ outward foreign direct investment (OFDI) decisions. We construct an economic growth index to assess the overall economic environment of Chinese regions and find that the home country’s business environment is negatively associated with firms’ decisions to invest abroad, and that such a negative relationship can be intensified for firms with state ownership or without an export network. Moreover, unlike previous literature, we look at both the environmental effect on OFDI decisions and the consequential impact of OFDI on firm performance. We employ propensity score matching and difference-in-differences methods, as well as the Heckman two-step model, for our estimations. Our results show that OFDI does indeed improve Chinese firms’ productivity and sales. This paper, therefore, contributes to the literature by identifying a range of home country business environmental factors that have a combined effect on firms’ OFDI decisions, adding to a more comprehensive understanding of OFDI originating from emerging economies.     

Credit and business cycles’ relationship: evidence from Spain

This study provides evidence on the interaction between business and credit cycles in Spain during the period 1970–2014. The paper works on three analyses: the cycle turning points are identified; the main features of credit and business cycles are documented; and in both cycles the causal relationship is assessed. We find differences in the features of the business and credit cycle phases, which lead to a scant degree of synchronization over time. The lack of synchronization might be a sign that the cyclic interaction could be non-contemporaneous. Our results reveal that there is causation. A significant lagged relationship between business and credit cycles is found; specifically, fluctuations of the business cycle lead fluctuations of the credit to non-financial corporations and a lag exists with respect to the fluctuations of the credit to households. We also examine episodes of credit boom and credit crunch. In the period 1970–2014, Spanish credit booms did not involve deeper business cycle contractions and credit crunches were not associated with deeper and longer business cycle contractions. These differences are related with the great importance of the real estate sector in Spain.     

Law environment,government regulation and implicit contract: Empirical evidence from the scandals of China’s listed companies

In China’s transitional economy, government regulation could be a substitute for the lack of law mechanism and regulator’s power could spill over into other areas not regulated. Then, theoretically it could construct implicit contracts. For example, China Securities Regulatory Commission (CSRC) has the rights to choose initial public offering(IPO) firms among applicants. It might construct implicit contracts between CSRC and local governments if the former consider the frequency and the severity of the scandals among different areas. Local governments could make decisions on whether and how much to implement the implicit contracts.     

Exchange rate disconnect and financial constraints —evidence from Chinese firms

One puzzling observation in international economics is the lack of response of exports to exchange rate fluctuations. Employing the most comprehensive export data from China for the 2000–2007 period, we provide sector- and firm-level evidence that the response of exports to exchange rate movements depends crucially on the level of financial constraints. For sectors with large financial constraints, the response is small, whereas, for less financially constrained sectors, the response can be much larger, with the estimated elasticity decreasing with the sector's degree of financial constraints. At the firm-level, financial constraints affect the firm's response to exchange rate shocks at both the intensive and the extensive margins. At the intensive margin, financial constraints dampen the effect of exchange rate on exports by restricting the firm's export value to the existing destination market; at the extensive margin, financial constraints restrict the number of firms participating in exporting, the number of firm-product pairs being exported, and the probability of entering a new destination market.     

R&D spillover effects on firms’ export behavior: evidence from South Korea

This paper investigates the spillover effects of R&D investments made by foreign multinational enterprises (MNEs) and domestic firms on their export activities, using a manufacturing firm-level panel dataset from South Korea. The theoretical framework predicts two conflicting spillover effects: positive technology spillovers and negative market rivalry spillovers. Thus, the net spillover effect is determined by the relative degree of the two conflicting spillovers. The empirical results show that negative intra-industry spillovers exist from the R&D of foreign MNEs on the export performance of firms, which implies that, in general, negative market rivalry spillovers dominate positive technology spillovers. However, notably, in the case of firms equipped with absorptive capacity, the negative spillovers can be alleviated; firms can gain positive spillovers by muting negative ones. Firms without absorptive capacity cannot avoid such negative effects. This paper shows that absorptive capacity is vital in capturing positive spillovers as firms build competency by accumulating their own know-how and improving their ability to capture better external technologies.     

Impact of split share structure reform on capital structures: empirical evidence from China’s listed companies

An econometric model based on a natural experiment and the difference-in-differences method is introduced to empirically investigate the impact of split share structure reform on capital structures. A total of 1026 listed companies in Chinese A-share during 2001–2011 are used as the sample for the research and interest-bearing debt ratios (BDRs) are taken as a representative indicator for capital structures. The theoretical and empirical analysis indicates that both market expansion effect and corporate governance effect caused by the split share structure reform are associated with an increase in BDR. As far as the timeliness is concerned, the effects of split share structure reform on capital structures will last 3–4 years.     

Natural disasters and university enrolment: evidence from L’Aquila earthquake

Although there are several studies looking at the effect of natural disasters on economic growth, less attention has been dedicated to their impact on educational outcomes, especially in more developed countries. We use the synthetic control method to examine how the L’Aquila earthquake affected subsequent enrolment at the local university. This issue has wide economic implications as the University of L’Aquila made a large contribution to the local economy before the earthquake. Our results indicate that the earthquake had no statistically significant effect on first-year enrolment at the University of L’Aquila in the three academic years after the disaster. This natural disaster, however, caused a compositional change in the first-year student population, with a substantial increase in the number of students aged 21 or above. This is likely to have been driven by post-disaster measures adopted in order to mitigate the expected negative effects on enrolment triggered by the earthquake.     

Involuntary excess reserve and bankers’ remuneration: evidence from Chinese banks

This article analyses the effects of involuntary excess reserves (IER) on bankers’ remuneration and the penalty associated with bank risk-taking if discovered. The study finds that IER help conceal tail risks, improves bankers’ performance and remuneration. However, the risks once discovered result in heavy penalties on bankers’ remuneration. The study extends the agency theory to the context where banks hold large IER.     

Biases in patent examination and firms’ responses: Evidence from the pharmaceutical industry

Empirical analysis of matched patent application data in the world’s major patent offices has shown considerable variation in patent granting probability and examination duration across different countries. This phenomenon is attributed to institutional misclassifications or patent examiners’ mistakes by some authors. Others argued that cross-country heterogeneity could also be caused by deliberate manipulation of patent examination procedures with the goal to foster native inventors through suppressing foreign patent applicants. To explore whether manipulation exists, this study presents a case study of pharmaceutical patents granted by the US patent office and approved by the US FDA. Especially it focuses on the filing behavior of pharmaceutical companies in Korea, Japan and China. The regression results show that the granting ratio of the previous applications of a foreign company is correlated with the company’s probability of lodging a new patent application, which provides a supplementary evidence of the existence of the manipulated patent examination procedures.     

The persistence of firms’ knowledge base: a quantile approach to Italian data

The paper investigates the patterns of persistence of innovation and of the properties of firms’ knowledge base (KB) across a sample of Italian firms in the period 1998–2006. The analysis draws upon a theoretical representation of knowledge as a collective good, stemming from the recombination of knowledge bits that are fragmented and dispersed across economic agents. On this basis, we derived properties of the KB like the coherence, the cognitive distance and the variety, and investigated their patterns of persistence over time. The empirical analysis is implemented by exploring the autocorrelation structure of such properties within a quantile regression framework. The results suggest that the properties of knowledge are featured by somewhat peculiar patterns as compared with knowledge stock, and that such evidence is also heterogeneous across firms in different quantiles.
