A generalized model for forecasting technological substitution

This paper presents a generalized mathematical model for forecasting technological substitution under a wide variety of circumstances. Some of the existing models are shown as special cases of the generalized model. Methods are also suggested for improving the reliability of the model by taking corrective measures on the available data and following a step-wise forecasting procedure.     

Public-private partnerships in micro-finance: Should NGO involvement be restricted?

This paper examines public–private partnerships in micro-finance, whereby NGOs can help in channelizing credit to the poor, both in borrower selection, as well as in project implementation. We argue that a distortion may arise out of the fact that the private partner, i.e. the NGO, is a motivated agent. We find that whenever the project is neither too productive, nor too unproductive, reducing such distortion requires unbundling borrower selection and project implementation, with the NGO being involved in borrower selection only. Further, we compare and contrast two alternative credit delivery mechanisms, the linkage mechanism (which is the focus of this paper), with the ‘Grameen’ one.     

Designing a reverse logistics network for optimal collection, recovery and quality-based product-mix planning

This study proposes an integrated, reverse logistics supply chain planning process with modular product design that produces and markets products at different quality levels. A mixed integer programming (MIP) model formulates the overall planning process required to maximize profit by considering the collection of returned products, the recovery of modules and the proportion of the product mix at different quality levels. This paper proposes the collection of returnables (end-of life, defective, product under warranty) through retail outlets combined with the recovery of modules from the collected products using a network of recovery service providers. The proposed modular product design approach would create a design criterion that provides an improved recovery process at a lower cost. This study uses a total supply chain view that considers the production, transportation and distribution of products to customers, while a numerical problem illustrates the applicability of the models.     

Religiosity and Voluntary Simplicity: The Mediating Role of Spiritual Well-Being

Although there has been considerable theoretical support outlining a positive relationship between religiosity and voluntary simplicity, there is limited empirical evidence validating this relationship. This study examines the relationships among religious orientations (Allport and Ross in J Pers Soc Psychol 5(4):432–443, 1967) and voluntary simplicity in a sample of Australian consumers. The results demonstrate that intrinsic religiosity is positively related to voluntary simplicity; however, there is no relationship between extrinsic religiosity and voluntary simplicity. Furthermore, this research investigates the processes through which intrinsic religiosity affects voluntary simplicity. The relationship between intrinsic religiosity and voluntary simplicity is sequentially mediated by communal/personal well-being and environmental well-being. The findings not only identify a prosocial role of intrinsic religiosity in motivating voluntary simplicity, but also indicate that secular pursuits that enhance communal/personal well-being and environmental well-being may also motivate voluntary simplicity.     

Group Contests with Internal Conflict and Power Asymmetry

We investigate simultaneous inter‐ and intra‐group conflict in the shadow of within‐group power asymmetry and complementarity in members' group‐conflict efforts. A more symmetric group faces a higher degree of internal conflict, and might expend more effort in external conflict when the group‐conflict effort technology is highly complementary. Depending on the degree of complementarity, the stronger player's relative contribution to external conflict might be higher in a more asymmetric group and, as a result, it is possible for the weaker player to earn a higher payoff. In the absence of any complementarity, the rent‐dissipation is non‐monotonic with the within‐group power asymmetry.     

Heterogeneity,leveling the playing field,and affirmative action in contests

The heterogeneous abilities of players in various competitive contexts often lead to undesirable outcomes such as low effort provision, a lack of diversity, and inequality. A range of policies is implemented to mitigate such issues by enforcing competitive balance, that is, by leveling the playing field. Some of those policies, known as affirmative action (AA) policies, are practiced in ethical response to historical discrimination against particular social groups, and are also aimed at increasing competition. This survey summarizes the rapidly growing literature on contest theory regarding AA and other policies that level the playing field. Using a general theoretical structure, we outline the theoretical, experimental, and empirical research findings on contest outcomes under a multitude of policy mechanisms, and in doing so, we touch upon some of the common debates in the AA literature.     

Shannon's Entropy and Its Generalisations Towards Statistical Inference in Last Seven Decades

Starting from the pioneering works of Shannon and Weiner in 1948, a plethora of works have been reported on entropy in different directions. Entropy‐related review work in the direction of statistical inference, to the best of our knowledge, has not been reported so far. Here, we have tried to collect all possible works in this direction during the last seven decades so that people interested in entropy, specially the new researchers, get benefited.     

Macroeconomic impacts of remittances in Bangladesh: The role of reverse flows

Das and Serieux (2010; 2015) and Serieux (2011) used the term “reverse flows” to define the part of external resources that is not domestically absorbed; instead used to finance debt obligations, capital flight, and accumulate reserves. While there is a vast literature on the growth and development impact of remittances in developing countries, the existing empirical literature has mostly ignored the potential diversion of remittances to reverse flows. This paper bridges the gap in the literature by estimating the reverse flows in the case of Bangladesh, which is one of the top remittance recipient countries in the world. The data set runs from 1976 to 2015. Econometric results obtained by employing the Autoregressive Distributed Lag (ARDL) approach show that almost 13–14% of remittances (as the ratio of gross domestic product, GDP) are diverted to finance reverse flows. In other words, the effects of remittances (as the ratio of GDP) on consumption and investment rates are no more than 86–87%. Therefore, the underlying assumption made in the existing literature that all remittances are used to increase consumption and/or investment overstates the impact of this external resource flow in Bangladesh. Findings from this study have important policy implications not only for Bangladesh but for other remittance recipient developing countries. Our findings will help the government to design policies to ensure the optimum allocation of remittances in the domestic economy.     

Social business collaboration at the bottom of the pyramid: The case of orchestration

Social business orchestrators (SBOs) help social businesses of various sizes to tackle major societal issues by filling gaps in knowledge and resources. However, research has overlooked these types of collaboration. Situated within a bottom of the pyramid context in Bangladesh, the current study sheds light on the process of value creation for SBO–social businesses partnerships by comparing different collaboration partners. Multiple case study research through the lens of the relational view were used to ask how SBOs facilitate value creation in social businesses by flexibly adapting resource inputs and governance mechanisms to the specific endowment and size of partners; this approach was informed by interviews and field note analyses. The combined deductive–inductive analysis enhances knowledge of idiosyncrasies of SBO–social business collaborations. Our study draws attention to the role of large orchestrators, whose model could be scaled and transferred to other world regions, including industrialised countries.     

Circular economy to enhance sustainability of small and medium‐sized enterprises

The circular economy (CE) represents a major paradigm shift of moving from the concepts of linear to circular supply chains across multiple industries. Although some aspects of CE adoption within industrial supply chains have been researched extensively (particularly addressing challenges of design, implementation, and operations), the research that relates CE practices with sustainability performance to reveal the current state of CE practices within small and medium‐sized enterprises (SMEs) is scant. The aim of this research was to facilitate SMEs to achieve greater sustainability through CE implementation. This research addresses three research questions—How are CE fields of action related to sustainability performance? What are the issues, challenges, and opportunities of adopting CE in SMEs? And what key strategies, resources, and competences facilitate effective implementation of CE in SMEs? This study adopts a mixed method approach (qualitative and quantitative) using survey research, focus group, and case studies; 130 randomly selected SMEs within the Midlands of the United Kingdom have been surveyed, and the responses are analysed using statistical tools along with findings from focus groups and case studies. The study reveals that all CE fields of action (take, make, distribute, use, and recover) of SMEs are correlated to economic performance, but only make and use are related to environmental and social performance. The study further derives strategies, resources, and competences for achieving sustainability across all the CE field of actions. Additionally, this research reveals the issues and challenges, strategies, resources, and competences required for implementing CE in SMEs.
