Customer motivations for sustainable consumption: Investigating the drivers of purchase behavior for a green‐luxury car

The purpose of the study is to investigate the effect of status motivation on customers' purchase intention of a green‐luxury car associated with owning a green‐luxury car, and whether materialism and horizontal–vertical individualism/collectivism moderate this relationship. The quantitative research methodology using online survey technique was used to collect cross‐cultural data from respondents (507) from China and Germany. Purposive sampling technique was used to identify and collect data from current and prospective customers of the BMW brand. Collected data were analyzed using structural equation modeling (SEM). The results demonstrated that materialism and cultural value (horizontal–vertical collectivism and vertical individualism) can serve as moderators of the effects of status motivation and purchase intention of the green‐luxury car. Although some studies have explored the factors involved in customer purchasing behaviour for green‐luxury products, our results theoretically and empirically show that materialism, vertical individualism, horizontal collectivism, and vertical collectivism enhance the positive effects of status motivation on customer purchasing behaviour for a green‐luxury car.     

Reconceptualizing Informal Work Practices: Some Observations from an Ethnic Minority Community in Urban UK

Whilst paid informal work has been conceptualized as a form of paid employment imbued with solely economic motivations, this article critically argues that such a market‐­oriented reading fails to take into account alternative explanations for the existence of informal work practices. Using evidence from 50 interviews conducted within a Pakistani urban community in a northern UK city, this article, uses a mixed‐embeddedness perspective to highlight the importance of predominantly socially and culturally driven motives in the decision to engage in informal work. The findings highlight that participation in informal work, whilst a product of marginalization due to certain institutional and structural factors, is also driven by a range of non‐monetary motives—a result of certain socially embedded work relations between ethnic minority workers and their employers. It is this social embeddedness of the employer–employee relationship in the Pakistani ethnic minority community that explains the continuation of informal work practices in the face of prevailing laws and regulations. The findings add weight to the understanding of informal work as being about more than just economics and constraints, offering these ethnic minority workers opportunities, even status, and giving them agency in an otherwise disempowered situation.     

Mixture cumulative count control chart for mixture geometric process characteristics

A statistical process control chart named the mixture cumulative count control chart (MCCC-chart) is suggested in this study, motivated by an existing control chart named cumulative count control chart (CCC-chart). The MCCC-chart is constructed based on the distribution function of a two component mixture of geometric distributions using the number of items inspected until a defective item is observed ‘n’ as plotting statistics. We have observed that the MCCC-chart has the ability to perform equivalent to the CCC-chart when number of defective items follows geometric distribution and better than the CCC-chart when the number of defective items produced by a process follows a mixture geometric model. The MCCC-chart may be considered as a generalized version of CCC-chart.     

Corporate social responsibility and Islamic banks: a systematic literature review

Although CSR is an extensively studied topic, a systematic, comprehensive and diverse review in the domain of CSR and Islamic banking is missing. This paper intends to present a broad review of this domain. Through a state-of-the-art review, we have divided the paper into different sections, the first two are general i.e. CSR measurement, it deals with measuring methods of CSR in Islamic banking, and CSR theories, it gives a brief overview of theories referred in under-review studies. While, the other three sections are separated according to the nature of studies i.e. CSR narrative under the Islamic paradigm, CSR disclosure by Islamic banks, and CSR exposition in Islamic banks. At the end of each section, we have included a ‘commentary’ to discuss and summarize major points, highlight trends and issues, provide insights into limitations and suggest future research directions.

Determining the optimal capacity and occupancy rate in a hospital: A theoretical model using queuing theory and marginal cost analysis

We model the hospital as seeking to balance the costs to itself in providing care, as well as the societal cost of people waiting for care. We use queuing theory to show that the optimal capacity and the corresponding optimal occupancy rate are dependent on the marginal cost of expanding capacity, the marginal cost of waiting, and the rates of patient arrival and discharge. Therefore, a universal occupancy target is unfounded. As well, the model shows that increasing capacity to respond to increased patient influxes is inadequate, suggesting that the health care system must explore alternate responses to burgeoning patient populations.     

Industry 4.0 and the circular economy: A literature review and recommendations for future research

Research regarding the Fourth Industrial Revolution (Industry 4.0) and the circular economy has gained traction since 2014. Paralleling the growth in the internet of things (IoT), the circular economy poses both risks and opportunities to various stakeholders in its development. This literature review aims to identify Industry 4.0 stakeholders' interests and expectations regarding how the IoT can be part of circular economy management. Contributions include identifying various IoT tools for dealing with circular economy challenges while also addressing implementation best practices. The transition of the circular economy within Industry 4.0 requires a better understanding of government, suppliers, international organizational interests, and expectations regarding the IoT. This study enables future research on circular economy practices and their potential sustainability benefits for manufacturing firms. This study's findings allow practitioners and researchers to understand the literature and critical elements of the transition toward a more circular economy.     

Volatility Decomposition and Correlation in International Securitized Real Estate Markets

This study contributes to the literature in international securitized real estate market volatility in three ways. Each market’s conditional volatility is decomposed into a “permanent” or long-run component and a “transitory” or short-run component via a component-GARCH model. Even though with the same number of common factors derived from the “permanent” and “transitory” volatility series, their loadings are not similar and consequently the long-run and short-run volatility linkages for some markets are different. Finally there are significant volatility co-movements between real estate and stock markets’ “permanent” and “transitory” components suggesting that real estate markets are at least not segmented from stock markets in international investing.     

A more general class of biased estimators of the co-efficients in linear regression

In a recent paper, Ullah and Ullah (1978) proposed a class of biased estimators, namely double k-class (k₁, k₂) for the coefficients in a linear regression model. Even though, this set of estimators contains James and Stein (1961) as a special case, in its present form, it does not contain the ridge type estimators. The aim of this note is to extend Ullah and Ullah set of estimators and then establish a relationship with the various operational ridge estimators. The conditions under which the extended set of estimators dominates the ordinary least squares estimator are analyzed.     

Organic versus cosmetic efforts of the quality of carbon reporting by top New Zealand firms. Does market reward or penalise?

This study explores the quality of carbon reporting (QCR) by New Zealand (NZ) firms and its changes over time. It also explores the impact of QCR on the market reputation of firms. Using a sample of 300 company-year observations between 2015 and 2020 from top listed firms of NZ, the study develops a 14-item QCR index. The study finds that the company-level QCR reporting by NZ firms overall is not praiseworthy, as firms need to improve QCR in many aspects (both in-house efforts as well as external reporting). Although QCR has increased over time, firms' QCR efforts cannot be treated completely authentic. Majority of firms in NZ have disclosed unaudited carbon information to investors and other stakeholders. Additionally, our study finds that QCR positively affects the market reputations of firms, and the market behaves accordingly. Specifically, firms' organic carbon efforts are paid-off (through increased market reputation) by the market players and cosmetic/decoupled behaviour is penalised (through decreased market reputation). This study is the first on QCR reporting using a sample of NZ firms and an account of their initiatives towards the carbon emission reduction initiative and related disclosures. The study's findings have policy implications.
