Abstract

Purpose

By testing the weak form of efficient market hypothesis (EMH) this study aims to forecast the short-term stock prices of the US Dow and Jones environmental socially responsible index (SRI) and Shariah compliance index (SCI).

Design/methodology/approach

This study checks the validity of the weak form of EMH for both SCI and SRI prices by using different parametric and non-parametric tests, i.e. augmented Dickey-Fuller test, Philip-Perron test, runs test and variance ratio test. If the EMH is invalid, the research further forecasts short-term stock prices by applying autoregressive integrated moving average (ARIMA) model using daily price data from 2010 to 2018.

Findings

The research confirms that a weak form of EMH is not valid in the US SRI and SCI. The historical data can predict short-term future price movements by using technical ARIMA model.

Research limitations/implications

This study provides better guidance to risk-averse national and international investors to earn higher returns in the US SRI and SCI. This study can be extended to test the EMH of Islamic equity in the Middle East and North Africa region and other top Islamic indexes in the world.

Originality/value

This study is a new addition to the existing literature of equity investment and price forecasting by comparing and investigating the market efficiency of two interrelated US SRI and SCI.

Abstract

This chapter reviews the extent of influence new regionalism has had on the development of the education sector in South Asia. The history of South Asian Association of Regional Cooperation (SAARC) development, and its regional state-supported initiative, the South Asian University, reflect a multitude of local challenges to effective regionalization for cross-national educational development. The chapter describes and distinguishes the various forms of regional efforts for cooperation and integration among government actors, nongovernmental organizations, and local activist groups and forums, to chart certain key regional efforts to consolidate intraregionalism as well as establish interregional relations of educational development and policy with countries of sub-Saharan African region. It utilizes the transnational advocacy networks framework to understand and interpret diverse manifestations of interregional cooperation between nonstate partners in South Asia and sub-Saharan Africa.

Abstract

Purpose

This study aims to investigate and compare the characteristics of three topologies of moving-magnet linear oscillating actuator (LOA) based on their mover position. Positive aspects and consequences of every topology are demonstrated. Three topologies of axially magnetized moving-magnet LOA; outer mover, inner mover (IM) and dual stator (DS) are designed and examined. Due to its characteristically high thrust density and more mechanical strength, axially magnetized tubular permanent magnets (PMs) are used in these topologies.

Design/methodology/approach

LOAs are designed and optimized using parametric sweep, in term of design parameters and output parameters like thrust force, stroke and operating resonance frequency of the LOA. All the pros and cons of each topology are investigated and compared. Output parameters of the LOAs are compared using same size of the investigated LOAs. Mover mass, which plays a vital role in resonant operation, is analyzed for IM and DS designs. Investigated LOAs are compared with conventional designs of LOA for compressor in refrigeration system with regards of motor constant, stroke and thrust per PM mass.

Findings

This paper analyzes three topologies of moving-magnet LOAs. The basic difference between investigated LOAs is the radius of tubular-shaped mover from its central axis. All the design parameters are compared and concluded that thrust per PM mass of IMLOA is maximum. OMLOA provides maximum motor constant of value 180 N/A. DSLOA provides thrust force with motor constant 120 N/A and required intermediate materials of PMs. All the three designs give the best results in terms of motor constant and thrust per PM mass, compared to conventional designs of LOA.

Originality/value

This paper determines the impact of mover position from its central axis in a tubular-shaped moving-magnet LOA. This work is carried out in correspondence of latest papers of LOA.

Abstract

Subject area

This case study has been written to illustrate the basic difference between goods and services, the difficulties of customer education in a developing county and the transition from goods to goods-cum-services for a company.

Study level/applicability

This is an ideal case to be taught in the second class of service marketing at the BBA level and will highlight the differences between goods and services in the same company.

Case overview

Haseen Habib is a company selling a combination of products and services in Pakistan. It is involved in the supply of fire protection equipment together with the provision of training and other facilities to enable organizations to take a proactive approach to disasters caused by fire and the appropriate response in case of a fire related disaster. This dimension of business is still in the infancy stage in Pakistan, and few people actually realize the need for fire protection services. Safety, risk management and risk prevention are often matters which take a backseat in the corporate, industrial, residential and commercial spheres. The emphasis is on dealing with the aftermath of events rather than to prepare them in advance. The company has a very clear vision and mindset which aims at taking a proactive approach toward managing and preventing risk. They are the pioneers of the safety industry in Pakistan and hold a strong work ethic. The company imports its equipment from the USA, China and Europe. Their target market mainly includes high risk sectors including oil and gas, chemicals, textiles, paint, nuclear and defense. The product portfolio included firefighting equipment like fire extinguishers, safety items which included head-to-toe safety attire for industrial workers and fire alarm systems including smoke detectors. The company also provides different levels and kinds of training and has experienced staff trained abroad in state-of-the-art techniques. However, in Pakistan, investment in risk management is often considered unnecessary, and in such a situation, imparting knowledge is a considerable challenge. The case can be used to study a number of topics. It can be used in a services marketing class to highlight the ways in which services marketing differs from conventional marketing of goods. It can also be used in disaster management courses or to reflect the status and position of developing countries, such as Pakistan, in dealing with unexpected disasters and catastrophes.

Expected learning outcomes

Following are the expected learning outcomes: to appreciate the difference between goods and services; to understand the issues in moving from a goods-oriented to a service-oriented company; to understand the challenges facing Haseen Habib in the context of customer education, keeping in mind it is functioning in an emerging marketing with a particular socio-cultural context; and to propose a way forward for Haseen Habib.

Abstract

Purpose

To improve the loan repayment performance (LRP) of microfinance banks (MFBs) in Pakistan, this study aims to look at the direct impact of multiple borrowing (MB) on LRP and client-business performance (CBP), as well as the direct impact of CBP on LRP. The moderating function of pandemic factors in the relationship between MB and CBP, as well as the mediating effect of CBP in the association between MB and LRP, was also investigated in this study.

Design/methodology/approach

A questionnaire was used to obtain data from 531 lower-level workers of microfinance institutions (MFIs) for the study. The respondents were chosen using stratified sampling, which divided the target population into four influential groups: lending officers in agriculture, lending officers in businesses, lending officers in gold loans and lending officers in salary loans. In this study, a two-stage structural equation modeling approach was used, including a measurement model (outer model) and a structural model (inner model). The validity and reliability of the questionnaire were investigated using the measurement model (outer model), whereas PLS-SEM bootstrapping was performed to test the hypothesis and find the relationship among different underpinning constructs by using the structural model (inner model).

Findings

The outcomes of this study demonstrate that MB has a direct impact on CBP, and that CBP has a direct impact on LRP. MB, on the contrary, had no direct and significant impact on LRP in this study. The idea that CBP mediates the relationship between MB and LRP, as well as the moderating effect of pandemic factors on the relationship between MB and CBP, is supported by this research.

Originality/value

Until now, the influence of MB on LRP via the mediating role of CBP and the moderating role of a pandemic factor in the setting of Pakistani MFBs has received little attention. During the COVID-19 pandemic, this research also aids MFBs in better understanding MB and its impact on LRP. Furthermore, based on the findings of this study, Pakistani MFIs can enhance their LRP by implementing new lending regulations, particularly with reference to MB and the COVID-19 pandemic.

Abstract

Purpose

The purpose of this study is to investigate the moderating impact of corporate governance (CG) on the relationship between economic policy uncertainty (EPU) and the sustainable growth (SG) of Chinese firms.

Design/methodology/approach

The study collects data of 975 Chinese non-financial listed firms for the period from 2010 to 2017. The study measures SG using a comprehensive index based on nine financial indicators and applies industry and year fixed effects regression to investigate the direct and moderating impact of CG on the relationship between EPU and SG of Chinese firms.

Findings

The results of the study explain that EPU negatively affects SG, while concentrated ownership, board independence and board gender diversity (BGD) positively contribute to the SG of the Chinese firms. The results also explain that concentrated ownership and BGD reduce the negative impact of EPU on the SG of the Chinese firms.

Research limitations/implications

The study considers only non-financial firms; therefore, the results of this study cannot be generalized for financial firms. Future research can be carried out while considering financial firms as a unit of analysis.

Practical implications

The investigation of the negative impact of policy uncertainty on SG is essential for the government and policymakers to devise policies to reduce uncertainty. The investigation of the moderating effect of CG enriches the literature on corporates’ response to policy uncertainty. It provides valuable insights for corporates regarding CG mechanisms to attain SG.

Originality/value

To the best of the authors’ knowledge, this is the first study that investigates the moderating impact of CG on the SG of Chinese firms using an index-based measurement of SG.

Abstract

Purpose

This study aims to investigate the relationship between bank policy-related practices and green financing sustainability in Pakistan. The study uses a mediating-moderation analysis to examine how the influence of bank policies on green financing sustainability is mediated by green banking activities and moderated by the employees’ green value and green knowledge sharing.

Design/methodology/approach

In this study, a structural questionnaire was used to gather data from Pakistani bank personnel through stratified sampling. A two-stage structural equation modelling approach was used in this investigation. The measuring scale’s validity and reliability are assessed using the measure model. A structural model was used to ascertain the connection between the underpinning constructs.

Findings

This study found a positive significant effect on bank employed related practices on green banking activities, besides the mediate role of green banking activities between the bank policies-related practices and green financing. In addition, this study also found the moderating role of employees’ green value and green knowledge sharing on the relationship of bank policies-related practices and green banking activities as well as green banking activities and green financing, respectively.

Originality/value

As environmental sustainability becomes more and more important on a worldwide scale; the study looks into the ways that financial institutions may become more environmentally conscious and help create a more sustainable future. To shed light on the ways in which financial institutions can be crucial in advancing green sustainability in an emerging economy such as Pakistan, this study used sophisticated statistical tools.

Abstract

Purpose

Drawing upon the institutional theory, this study examines the influence of responsible leadership on firm performance. Furthermore, this research investigates environmental management practices (EnvMP) as an underlying mechanism and institutional pressures as boundary condition between responsible leadership and firm performance.

Design/methodology/approach

Time-lagged data were collected using survey-questionnaire from 385 mid-level employees of construction industry in Pakistan. Partial least square-structural equation modeling (PLS-SEM) was used to analyze the data.

Findings

Results demonstrate that responsible leadership impacts firm performance (financial and nonfinancial) directly and through EnvMP. Furthermore, institutional pressure moderates the link between responsible leadership and EnvMP. However, moderated mediation effect of intuitional pressures was found insignificant.

Practical implications

This study suggest that EnvMP is a key process through which responsible leadership influences firms' financial and nonfinancial performance and shed lights as to when responsible leaders matter most in terms of firm performance through low or high institutional pressures.

Originality/value

This paper is an early attempt which contributes to the body of literature on responsible leadership by investigating mechanisms (how) and boundary condition (when) through which responsible leadership influences firms' financial and environmental performance.

Abstract

Purpose

This study aims to investigate earnings management practice of classification shifting of revenues in Chinese-listed firms.

Design/methodology/approach

The study employs a dataset of 2,920 A-listed firms from Chinese stock exchanges of Shanghai and Shenzhen for the period of 2003–2019. We apply both univariate and panel regression analysis by using fixed effect estimation with robust standard errors.

Findings

Our findings reveal that firms misclassify revenues by taking advantage of the flexibility provided by applicable financial reporting standards. The empirical evidence obtained through regression analysis suggest that managers reclassify non-operating revenues as operating revenue to alter the economic reality while seeking the advantage of financial reports users’ vulnerability for valuing the upper half of income statement items more as compared to lower part. The results further indicate that international financial reporting standards adoption inhibits the earnings management practices using classification shifting of revenues. It is also concluded that firms, which are suffering losses or having low growth, are more persistently involved in misclassification of revenues.

Originality/value

The study is unique from the point of view that it investigates earnings management from the prospective of revenue’s classification in an emerging market characterized by various market imperfections such as lower investor protection and higher information asymmetry.

Abstract

Purpose

This study aims to reconcile and address Bowman’s paradox empirical criticism from the lens of financial theory, corporate strategy and their econometric adversaries based on three issues, i.e. risk conceptualization, measurement and econometric modeling in Asian emerging countries (AEC).

Design/methodology/approach

The study is conducted on panel data sampling from 2,872 firms across four Asian Emerging Countries (AEC) and employs a two-stage least squares (2SLS) estimation technique. We proposed a theoretical framework based on triangulation that outlines four risk-return relationships based on proxies derived from capital market and firm-level data and used different econometric models to answer Bowman’s paradox ongoing criticism.

Findings

The empirical results negate the empirical artifact viewpoint in AEC. The risk-return relationship estimated on firm accounting-based ratios or its combination with market-based measures supports Bowman’s paradox and thus upholds the corporate strategy point of view. Whereas the risk-return relationship based on market-based ratios upholds the financial theory point of view. However, the results are mixed when risk is subdivided into systematic and business risk. Our results are robust across standard deviation and semi-standard deviation-based measures of risk, and there is no evidence of a non-linear relationship.

Originality/value

A compelling debate exists that Bowman’s paradox is an empirical artifact. We provide an innovative approach that aims to reconcile and address the ongoing debate by employing diverse risk-return proxies and econometric models in Asian emerging countries. Methodological issues such as endogeneity, sample biases, temporal fluctuations, downside risk variations, multiple moments of a variable and model misspecification are also addressed. This triangulation enhances the robustness of our analysis, providing a comprehensive perspective on AEC and laying the groundwork for future researchers to explore Bowman’s paradox through alternative measures and models.
