Purpose Previous research has found that industry concentration and firm efficiency affect stock returns. However, it is not clear if concentration is a byproduct of efficiency and hence its effect on stock returns is driven by efficiency. This paper aims to examine the relationships between industry concentration, firm efficiency and average stock returns. Mainly, it aims to answer if the effects of industry concentration and firm efficiency on stock returns are independent and significant. Design/methodology/approach The stochastic frontier approach is used to estimate firm efficiency. The Herfindahl index is used to measure industry concentration. Regression and vector autoregressive analyses are performed to examine cross-sectional and lagged relationships between concentration, efficiency, profitability and stock returns. The characteristics-based benchmark approach is also used to investigate performance of test portfolios. Findings Industry concentration and firm efficiency have independent and significant effects on average stock returns through profit margins and market shares, which are related to firms’ profitability. Industry concentration has a greater positive impact on market shares than on profit margins, whereas firm efficiency has a greater positive impact on profit margins than on market shares. In sum, highly efficient firms in highly concentrated markets have lower distress risks and hence provide lower average stock returns. Originality/value The paper shows the linkages between industry concentration, firm efficiency, profitability and stock returns that have not been documented together in prior studies. Businesses can better understand the impact of concentration and efficiency on market shares and profit margins. Researchers may consider incorporating concentration and efficiency, both of which are meaningful microeconomic variables, into an asset pricing model. Investors can enhance their returns by having a zero-cost portfolio with long and short positions in stocks of firms with different levels of concentration and efficiency.

The Impact

Purpose The existing literature has established the importance of industry concentration in explaining firm performance and information environments. However, little is known about whether and how industry concentration affects investors’ ability to anticipate future earnings. This paper aims to investigate this query by identifying and testing two channels, product market power and intra-industry information transfer, through which industry concentration affects the informativeness of stock returns about future earnings. Design/methodology/approach The paper measures the informativeness of stock returns about future earnings by the future earnings response coefficient (FERC)). This study estimates the FERC using a firm-level sample from 38 economies. Findings The authors find that industry concentration significantly enhances investors’ ability to predict future earnings. Further tests show that both product market power and intra-industry information transfer contribute to explaining the positive association between industry concentration and the FERC, with the former playing a more salient role. Finally, the authors show that a country’s effective competition law attenuates the positive impact of industry concentration on the FERC by weakening the economic impact of the two underlying channels. Originality/value This study contributes to the growing literature on the price-leading-earnings relation, industry concentration and international corporate governance.

Purpose Many construction businesses are currently building and keeping social media pages for their enterprises to be visible to the public to improve their social interaction, promote business interest, build trust and relationships with their targeted audience on social media. The purpose of this study is to examine the impact of social mediausage on performance of construction businesses (CBs) in Abuja, Nigeria. Design/methodology/approach This study used a quantitative research approach by identifying constructs that reveal three aspects of organisation’s physiognomies that impact the process of espousing, implementing and using technological innovations in conducting businesses. Well-structured questionnaire was used to obtain data from 113 purposively sampled building materials’ merchant operating in Dei-Dei Market, Abuja, Nigeria. This study used partial least squares structural equation modelling technique to establish the relationship among the constructs. Findings The results of this study indicated that technology has significant relationship with social media adoption, whereas social media adoption has a very strong positive impact on organisation’s performance (P < 0.001) with respect to improved customer relations and services and enhanced information accessibility. Research limitations/implications This study has implications for CBs that wish to adopt social media to promote their businesses by presenting to them the opportunity to understand the impact of technology, environment and organisational potential in improving business performance. This study is cross-sectional in nature, and this calls for caution in interpreting the results. Originality/value This paper developed and tested a conceptual framework presented to understand the interrelationships amongst the constructs, which would be of great significance to business owners in developing their social interaction and promote business interest via social media. The outcome of this research is beneficial to researchers to further study how the different social media tools could help in influencing business decisions.

Irrigation production is a means by which agricultural production can be increased to meet the growing food demands in the world. This study evaluated the effect of irrigation ecology on farm household technical, allocative, and economic efficiency of smallholder rice farmers. Cross-sectional data was obtained from 350 rice farmers across rain fed and irrigation ecologies. Stochastic frontier analyses are used to estimate the production efficiency and endogenous treatment effect regression model is used to estimate the impact of irrigation ecology on rice production efficiency. The impact of irrigation ecology on technical efficiency is about 0.05, which implies farmers producing under irrigation ecology are more technically efficient in their rice production than those in rain fed production. The impact of irrigation ecology on allocative efficiency is about 0.33, which shows that farmers participating in irrigation farming are more allocatively efficient in their rice production than those in rain fed production. The impact on economic efficiency is about 0.23, meaning that farmers participating in irrigation farming are more economically efficient in their rice production than those in rain fed production. Irrigation ecology has positive impact on production efficiency; hence farmers should be encouraged to produce more under irrigation for increased yield and profit.

Purpose This paper aims to examine the impact of interest rate liberalization on economic growth and the relevance of corruption in the five selected sub-Saharan African countries. Design/methodology/approach The study used the modified version of Driscoll and Kraay’s model by Hoechle, which solved the effects of cross-sectional dependence and heteroscedasticity. Findings The findings reveal a positive impact of the index on economic growth, and it was found that foreign direct investment (FDI) and credit to private sector by banks (CPSB) all stimulate economic growth. The interaction terms of corruption with FDI and CPSB indicate negative effects that show how corruption erodes the benefits of liberalization. Finally, the paper recommends the pursuit of appropriate policies with the sole aim of eradicating corruption and providing a conducive environment for business. Originality/value The paper developed a composite domestic financial liberalization index to capture the timing and essential dimensions of the reform process. The study investigates the effect of interest rate liberalization on economic growth and the relevance of corruption. Most of the recent and past studies only examined the impact of interest rate reforms on growth without investigating the relevance of corruption.

PurposeThis paper aims to investigate patterns in UK stock returns related to downside risk, with particular focus on stock returns during financial crises.Design/methodology/approachFirst, stocks are sorted into five quintile portfolios based on the relevant beta values (classic beta, downside beta and upside beta, calculated by the moving window approach). Second, patterns of portfolio returns are examined during various sub-periods. Finally, predictive powers of beta and downside beta are examined.FindingsThe downside risk is observed to have a significant positive impact on contemporaneous stock returns and a negative impact on future returns in general. In contrast, an inverse relationship between risk and return is observed when stocks are sorted by beta, contrary to the classic literature. UK stock returns exhibit clear time sensitivity, especially during financial crises.Originality/valueThis paper focuses on the impact of the downside risk on UK stock returns, assessed via a comprehensive sub-period analysis. This paper fills the gap in the existing literature, in which very few studies examine the time sensitivity in relation to the downside risk and the risk-return anomaly in the UK stock market using a long sample period.

Purpose – The purpose of this paper is to answer the following two questions: What are the HRM practices that have a significant impact on employees’ functional retention?, and Does the impact of these HRM practices on functional retention differ based on the employee’s status as an expert or a non-expert? Our theoretical foundation rests on human capital theory and social exchange theory. Design/methodology/approach – This study uses longitudinal data that come from multiple surveys conducted on new employees within a Canadian subsidiary of an international information technology (IT) firm. Findings – Results show that four out of five HRM practices under study have a significant and positive impact on functional retention of employees regardless of their expert status: satisfaction with a respectful and stimulating work environment, satisfaction with training and development, satisfaction with innovative benefits and satisfaction with incentive compensation significantly increase functional retention of employees. Functional retention was found to be higher for experts than for their non-expert counterparts. Last, results show that expert/non-expert status play a moderating role between HRM practices and functional retention. Originality/value – In short, this study offers five main contributions to the literature: first, it focuses on retention rather than turnover; second, it goes further by examining functional retention as the dependant variable; third, it distinguishes between two categories of employees: experts and non-experts; fourth, it extends the limited literature on IT workers, HRM practices and retention; and fifth, it is based on longitudinal data whereas the overwhelming majority of published studies have been based on cross-sectional data.

PurposeThe growth of socially responsible assets has been exponential over the last decade, they now account for almost a third of professional investments. As the growth persists, faith and conviction investors reshape the equity markets. To fully comprehend the impact of socially conscious participants on security returns, this paper attempts to provide insights on how responsible investment growth has impacted the returns of sustainable stocks. The examination is split by investment horizon to account for short and long effects.Design/methodology/approachUsing an exclusive dataset of non-financial ratings, provided by MSCI ESG research, the authors examine the cross-sectional returns of US and European sustainability-leading and lagging corporations between 2007 and 2019. Panel models robust to country, firm-year and industry effects were then employed to examine the impact of responsible investment growth on future stock returns.FindingsThe authors find evidence that the impact of responsible investment growth is dual contingent upon the timeframe considered. In the short run, sustainability-leading and lagging firms display similar stock returns. However, the spread in returns is negative over long horizons and increasing over time.Originality/valueThe examination performed in this study highlights the significant effect of responsible investment growth on future stock returns. Overall, the authors’ findings are consistent with the price pressure hypothesis in the short run and the cost of capital alteration over longer horizons.

Spirituality Development

PurposeThe unending ambivalence in the academic environment and the job market is detrimental to management graduates' wellbeing. The study looks into the possible intervening methods to enhance the wellbeing of students during difficult times. The study proposes spirituality development as means through which psychological resources like perceived employability and psychological capital are developed in an individual. This study also tries to identify how spirituality development leads to life wellbeing among management students.Design/methodology/approachCross-sectional study was conducted among 212 management students from Kerala, India. Multi-stage random sampling was used to collect data. Structural equation modelling using IBM-AMOS was done to gain insights into the proposed relationships.FindingsThe results indicated that spirituality had a significant impact on the wellbeing of management students. Both perceived employability and psychological capital mediated the relationship between spirituality and life wellbeing.Research limitations/implicationsThe positive impact of developing spirituality among students is discussed in the paper with the theoretical underpinning of broaden and build theory. The findings suggest that colleges should try to make their campus climate more supportive of students' non-academic needs and open them to a spiritual environment especially during these challenging times.Originality/valueThe study is one of the first attempts to discern how spirituality development leads to an accumulation of psychological resources and life wellbeing among management graduates'.

The Capital Structure

Purpose The purpose of this study is to investigate the effect of environmental performance on the capital structure and financial performance of Turkish listed firms. Design/methodology/approach This study used data of 49 firms listed on Istanbul Stock Exchange during the period between 2014 and 2019, resulting in 205 firm-year observations. The environmental performance data were drawn from the carbon disclosure project Turkey climate change reports. Ordinary least squares and binary logistic regression models were used to examine whether environmental performance impacts the capital structure and financial performance. Findings The findings of this research revealed that environmental performance significantly positively affects the firm leverage. Findings also showed that environmental performance has a significantly positive impact on return on assets, operating profitability and return on equity, but no significant impact on stock returns. Practical implications Given the increased borrowing costs for Turkish firms after the 2018 currency crisis in Turkey, the findings of this study are very important as they enable managers of Turkish firms to make better decisions related to capital structure and to understand the role of environmental performance in reducing the cost of debt and enhancing financial performance. Originality/value To the author’s knowledge, this research is the first to investigate the effect of environmental performance on capital structure in the Turkish context, and is one of few that explained how environmental performance affects the financial performance of Turkish firms.

Purpose A long history of literature has considered the role of information risk in determining the cost of equity. The question that has remained unanswered is whether information risk plays any systematic role in determining the cost of equity. One of the fundamental decisions that every business needs to make is to assess where to invest its funds and to re-evaluate, at regular intervals, the quality of its existing investments. The cost of capital is the most important yardstick to evaluate such decisions. Greater information is associated with the lower cost of capital via mitigating transaction costs and/or reducing estimation risk and stock returns. This study aims to investigate the impact of information risk on the cost of equity and corporate stock returns. Design/methodology/approach The research sample consists of 960 firm-year observations for companies listed on the Tehran Stock Exchange from 2009 to 2018. The research hypotheses were tested using multivariate regression models based on panel data. Findings The results reveal that information risk has a significant positive impact on the firm’s cost of equity. However, the impact of information risk on stock returns is not statistically significant. Originality/value To the best of the knowledge, the current study is almost the first of its kind in the Iranian literature which investigates the subject matter; therefore, the findings of the study not only extend the extant theoretical literature concerning the information risk in developing countries including the emerging capital market of Iran but also help investors, capital market regulators and accounting standard setters to make timely decisions.
