Stock Effect

Purpose The purpose of this paper is to determine if there is a significant difference in the investment risks between small-cap manufacturers that heavily depend on one or a few buyers, referred to as “dependent-buyers,” and small-cap manufacturers that have a more diversified customer base. If there is a significant difference both statistically and economically, then investors need to be aware of the dependent-buyer effect in their security selection and portfolio construction efforts. Design/methodology/approach Using large samples of firm-level data from 2000 through 2011, the authors employ standard risk estimation modeling to compute βs, idiosyncratic risks, and total risks of both dependent-buyer firms and firms with a more diversified customer base. Findings The authors find that the βs, idiosyncratic risks, and total risks of dependent-buyer firms are much greater than that of firms not in dependent relationships. These differences are both statistically and economically significant. Research limitations/implications Buyer-supplier relationships can change quickly, and so a firm that has a diversified base in one period, for example, could be a dependent-buyer in the next period. Much depends on the reporting accuracy of firms and the ability of the securities exchange commission (SEC) to track the relationships. Practical implications First, the risk of individual small-cap stocks is likely to be greater than perceived from macro-level data, leading to the need for more securities if idiosyncratic risk is to be eliminated. Second, small-cap investors have the opportunity to enhance portfolio construction efficiency by referencing data published by the SEC. Third, most investors interested in small-cap manufacturing stocks should find it prudent to allocate a large percentage of their small-cap investments to an index fund. While this may sacrifice higher returns, it also reduces the probability of experiencing an unpleasant small-stock effect. Originality/value This is the first study to show that the difference in investment risks between small-cap manufacturers that depend on one or a few firms for their outputs and small-cap manufacturers that have a well-diversified customer base is statistically and economically significant, information that should be valuable to investors in their security selection and portfolio construction efforts.

Purpose – The purpose of this paper is to verify the impacts of the transaction costs rationale on economic agents’ innovative results when they engage in European R & D networks, supplying both firms and policymakers with empirical support for improved decision making toward economic competitiveness and construction of the European research area. Furthermore, unlike many transaction cost economics assessments, the authors evaluate the existence of transaction costs following a dynamic framework of analysis (instead of using solely ex ante governance choice as a driver of inter-firm “friction” management), offering a novel perspective on these phenomena. Design/methodology/approach – Data consist of firm-level information from Eureka’s Final Reports (1995-2006) for Spanish, Italian, French, British and German firms. Empirical assessments were performed through a two-step approach of direct and indirect effects of network management and potential sources of disturbances. Ordinal regressions were applied in order to identify transaction costs’ relevance as drivers of firms’ technological and commercial outcomes, as well as on managerial quality of alliances. Statistical controls include microeconomic and project-specific variables. Findings – Results highlight the role played by transactional aspects as drivers of companies’ outcomes and managerial complexity. Furthermore, the authors find robust evidence that formal ex ante governance structures are incapable of satisfactorily addressing dynamic disturbances that take place within R & D networks. Whereas such findings are directly related to existing transaction costs, the authors find no support for the usual variables attributed to increased complexity in international inter-firm relationships. Research limitations/implications – Self-selection issues are inherently related to the research instrument (i.e. Eureka’s Reports), while further firm-level data could not be obtained since confidentiality issues protected companies’ names and sectors. Also, network-level data are not available, allowing the evaluation of individual perceptions only. Originality/value – While literature addresses the issue of transaction costs in R & D networks via theoretical assumptions and rough proxies, this assessment offers an in-depth evaluation of a set of valuable indicators with direct implications for researchers, managers and policymakers. Main contributions concern the identification of dynamic interactions (and their respective disturbances) as a key feature of the overall performance of R & D networks, stressing the non-linearity of economic processes in these hybrid relationships, an issue that has been poorly tackled by previous empirical investigations.

Finance Innovation

Purpose The purpose of this paper is to investigate how firms in developing countries finance innovation. Notably, the study seeks to investigate whether innovative firms exhibit financing patterns different from those of non-innovative ones. It also examines the effect of financing sources on firm’s probability to innovate. Design/methodology/approach The study utilizes firm-level data from the World Bank Enterprise Survey. From 28 African countries, 11,173 firms have been included in the sample. A statistical t-test is used for two independent samples and logistic regression models. Findings The results show that innovative firms, specifically innovative small- and medium-size firms exhibit financing patterns different from non-innovative peers. Further analysis indicates that there is no statistically significant difference between the financing patterns of innovative and non-innovative large firms. In Africa, innovation is mostly financed using internal sources and bank finance. Equity finance and bank finance have shown a higher effect followed by internal finance, finance from non-bank financial institutions and trade credit finance on firms’ probability to innovate. Practical implications The management of innovative firms should reduce dependency on short-term and retained earning financing and increase the use of long-term instruments improve innovation performance. Social implications A pending policy task for African leaders is to design and evaluate reforms to create a strong financial sector that willing to support the innovation process. Originality/value This study contributes to the existent literature on finance of innovation by examining how firms finance innovation activities in developing countries. This study provides evidence on how innovative firms exhibit financing patterns different from non-innovative ones from developing countries.

The Relationship

Purpose – The purpose of this paper is to examine whether the framework of Prospect Theory and Mental Accounting proposed by Grinblatt and Han (2005) can be applied to analyzing the relationship between the disposition effect and momentum in the Chinese stock market. Design/methodology/approach – The paper applies the methodology proposed by Grinblatt and Han (2005). Findings – Using firm-level data, with a sample period from January 1998 to June 2013, the authors find evidence that the momentum effect in the Chinese stock market is not driven by the disposition effect, contradicting the findings of Grinblatt and Han (2005) concerning the US stock market. The discrepancies in the findings between the Chinese and US stock markets are robust and independent of sample periods. Research limitations/implications – The findings suggest that Grinblatt and Han’s model may not be applicable to the Chinese stock market. This is possibly because of the regulatory differences between the two stock markets and cross-national variation in investor behavior; in particular, the short-selling prohibition in the Chinese stock market and greater reference point adaptation to unrealized gains/losses among Chinese compared to Americans. Originality/value – This study provides evidence of the inapplicability of Grinblatt and Han’s model for the Chinese stock market, and shows the differences in the relationship between disposition effect and momentum between the Chinese and US stock markets.

Purpose This paper investigates discrimination against women within the Brazilian labour market using firm-level data from the World Bank Investment Climate Survey. The purpose of this paper is to determine whether the female employees in the Brazilian labour market are paid less than their productivity warrants due to the existence of discrimination. Design/methodology/approach Based on employer discrimination model proposed by Becker (1971) that considered the proportion of female employees as a proxy for the extent of discrimination, the authors estimate the profit function using OLS analysis, and regress it on the proportion of female employees and other firm characteristics. To address the endogeneity problem caused by unobservable productivity shocks, the authors employed the methods proposed by Olley and Pakes (1996) and Levinsohn and Petrin (2003), respectively. Findings The results indicate that the proportion of female employees has positive effect on firms’ profit in 2002, but has no effect in 2007. This finding gives evidence of the existence of discrimination against female employees within the Brazilian labour market in the early 2000s, while the gender discrimination was reduced overtime. Originality/value This paper’s main contribution is to provide an approach that differs from that of previous research to determine whether discrimination exists within the Brazilian labour market. This paper also provides policy insights for Brazilian labour market.

Purpose The study aims to examine the importance of access to finance in firm innovation by using firm-level data from the World Bank enterprise survey (WBES) on selected African countries. Design/methodology/approach This study utilises firm-level data from the WBES database and computes aggregate innovation index by using multiple correspondent analysis. The authors then apply instrumental variable models (to control for possible endogeneity between innovation and finance) to assess the link between finance and innovation. Findings The research finds that finance in the form of overdraft overwhelmingly drives innovation in all selected countries – Cameroon, Kenya, Morocco, Nigeria and South Africa. Trade credit enhances innovation among firms in Nigeria, South Africa and Cameroon, while asset finance drives innovation amongst firms in Cameroon, Nigeria and South Africa. Practical implications Policy incentives such as tax breaks could be put in place for financial intermediaries that have shown proof of extending loans to financially constraint firms to enable them to innovate. Furthermore, different financial institutions such as microfinance institutions can be supported to increase credit to enterprises. Partnerships with organisations willing to fund firms and support start-ups should be encouraged. One of such support mechanisms could be specialised schemes such as a credit guarantee scheme to encourage and secure lending to enterprises to promote innovation. Originality/value This paper provides empirical insights into how finance enhances innovation in African enterprises. It also shows how different finance structures (overdraft, asset finance and trade credit) affect firm innovation in different African countries.

Practical Implications

Purpose – High-growth firms (HGFs) have attracted an increasing amount of attention from researchers and policymakers, and the Eurostat-Organisation for Economic Co-operation and Development (OECD) definition of HGFs has become increasingly popular. The paper aims to discuss this issue. Design/methodology/approach – The authors use a longitudinal firm-level data set to analyze the implications of using the Eurostat-OECD definition. Findings – The results indicate that this definition excluded almost 95 percent of surviving firms in Sweden, and about 40 percent of new private jobs during 2005-2008. Research limitations/implications – The proportion of small firms and their growth patterns differ across countries, and the authors therefore advise caution in using this definition in future studies. Practical implications – Policy based on the Eurostat-OECD definition of HGFs might be misleading or even counterproductive. Originality/value – No previous studies have analyzed the implications of using the Eurostat-OECD definition of HGFs.

Purpose The purpose of this paper is to make two main contributions: first, showcase the diversity of service research in terms of the variety of used theories and methods, and second, explain (post-publication) success of articles operationalized as interest in an article (downloads), usage (citations), and awards (best paper nomination). From there, three sub-contributions are derived: stimulate a dialogue about existing norms and practices in the service field, enable and encourage openness amongst service scholars, and motivate scholars to join the field. Design/methodology/approach A mixed method approach is used in combining quantitative and qualitative research methods while analyzing 158 Journal of Service Management (JOSM) articles on several criteria such as their theory, methodology, and main descriptive elements (e.g. number of authors or references) and then using automated text analysis (e.g. investigating the readability of articles, etc.). Findings The results show that the JOSM publishes a large variety of articles with regard to theories, methods of data collection, and types of data analysis. For example, JOSM has published a mixture of qualitative and quantitative articles and papers containing firm-level and customer-level data. Further, the results show that even though conceptual articles create the same amount of interest (downloads), they are used more (citations). Research limitations/implications This paper presents many descriptive results which do not allow for making inferences toward the entire service research discipline. Further, it is only based on one service research journal (JOSM) through a five-year span of publication. Practical implications The results have a number of implications for the discipline that are presented and discussed. Amongst them are that: the discipline should be more open toward conceptual articles, service research shows an imbalance toward theory testing, there is more potential to work with transactional data, and writing style should be more accessible (i.e. readable). Originality/value This paper is the first to conduct an in-depth analysis of service research articles to stimulate dialogue about common publishing practices in the JOSM and to increase the openness of the field.

Object. Glycerol is considered to be a marker of cell membrane degradation and thus cellular lysis. Recently, it has become feasible to measure via microdialysis cerebral extracellular fluid (ECF) glycerol concentrations at the patient's bedside. Therefore the aim of this study was to investigate the ECF concentration and time course of glycerol after severe traumatic brain injury (TBI) and its relationship to patient outcome and other monitoring parameters. Methods. As soon as possible after injury for up to 4 days, 76 severely head-injured patients were monitored using a microdialysis probe (cerebral glycerol) and a Neurotrend sensor (brain tissue PO2) in uninjured brain tissue confirmed by computerized tomography scanning. The mean brain tissue glycerol concentration in all monitored patients decreased significantly from 206 ± 31 µmol/L on Day 1 to 9 ± 3 µmol/L on Day 4 after injury (p < 0.0001). Note, however, that there was no significant difference in the time course between patients with a favorable outcome (Glasgow Outcome Scale [GOS] Scores 4 and 5) and those with an unfavorable outcome (GOS Scores 1–3). Significantly increased glycerol concentrations were observed when brain tissue PO2 was less than 10 mm Hg or when cerebral perfusion pressure was less than 70 mm Hg. Conclusions. Based on results in the present study one can infer that microdialysate glycerol is a marker of severe tissue damage, as seen immediately after brain injury or during profound tissue hypoxia. Given that brain tissue glycerol levels do not yet add new clinically significant information, however, routine monitoring of this parameter following traumatic brain injury needs further validation.

Purpose This paper aims to examine the effect of the Sarbanes–Oxley Act (SOX), which was signed by President George W. Bush and came into effect on July 30, 2002, on firm productivity. Design/methodology/approach The authors use the total factor productivity (TFP) as our measure of firm productivity. Findings Analyzing annual firm-level data from the Compustat database for the period of 1991-2006, the authors find that firm productivity increases at a higher rate in the post-SOX period. The results indicate that, although firms incur significant costs in complying with the requirements of the SOX, they also benefit from these requirements as evidenced by the improved productivity over time post-SOX. There is also a shift in the output elasticities from capital toward labor. The SOX has a positive effect on the output elasticity of labor but a negative impact on that of capital. Research limitations/implications The results have the following important implications. The SOX is a value-enhancing regulation in that it not only strengthens a firm’s corporate governance but also improves its productivity. However, compliance with the SOX can impose a long-term cost on firms: the decrease in the capital investment, leading to a decline in the output elasticity of capital. If this decline in the capital investment continues, it can have an adverse effect on firm productivity in the long term. Originality/value This paper extends the literature along the line of the actual operational effects of the SOX regulation by examining its effect on the productivity of firms.

Purpose As reporting environmental, social and governance (ESG) information is not yet mandatory in all countries, it is intriguing to understand ESG’s underlying driving mechanisms. This study aims to investigate ESG determinants in the banking sector of the Middle East and North Africa countries. Design/methodology/approach The authors gather data for 38 listed banks for the period 2011–2019. The data used is threefold as follows: data related to ESG; firm-level; and country-level data. While ESG and firm’s level data are taken from Refinitiv, country-level data are extracted from the World Bank. Using panel regression, the authors test the effect of firm- and country-specific variables on the overall ESG score and its pillars. Findings Results indicate that banks’ ESG scores are negatively affected by performance and positively affected by size. The level of economic development exerts a negative impact on the environmental pillar while the social development exerts a positive impact on ESG and governance pillar. Corruption is the only country-level that gathers a homogenous effect on ESG scores. Finally, the three pillars follow heterogeneous patterns. Originality/value This study extends the scope of previous studies by introducing new country-level independent variables to contribute to the understanding of ESG antecedents.
