A systematic literature review to integrate lean,agile, resilient,green and sustainable paradigms in the supply chain management

The main focus of this study is to conduct a systematic literature review to integrate lean, agile, resilient, green and sustainable (LARGS) paradigms in the supply chain (SC) domain. To achieve this aim, several research questions were designed: First, how to locate LARGS research in context of SC domain? For this, it is important to understand which types of research articles should be selected for the study? Further, where such studies were conducted (geographical location)? Second, what is the focus of research in LARGS paradigm in SCs? For this, it is important to study, which types of industries or sectors have been targeted in literature? In addition, which tools and techniques have been used mostly? Third, what are the current trends in the relationships of LARGS paradigms, among themselves, and with SC performance measures? Fourth, what are the emerging issues, unexplored areas in this field, based on these what could be future research avenues in this subject domain have been proposed? A total of 160 relevant articles published during 1999–2019 were used for analysis. Based on analysis, findings are summarised, and main research issues and possible future research directions in LARGS paradigms in SCs are highlighted.     

Supplier evaluation in the context of circular economy: A forward step for resilient business and environment concern

Resource depletion is a concern for the global economy; many think that available resources on the planet will not be able to cater to an ever-growing population. Thus, economies are trying to become circular, leaving behind the linear tradition linear approach. In the circular economy (CE), physical resources and energy are made to loop back into the supply chain (SC) for a more extended period. Proper selection of suppliers is an essential criterion towards proper execution of the CE principle in SC. In this research, we have constructed a framework for evaluating the supplier concerning the CE implementation. Further, this research identifies the criterion and sub-criterion, which are pertinent for evaluating the supplier in CE context. Fuzzy-based ‘Criteria Importance Through Inter-Criteria Correlation (CRITIC)’ method is justifiably applied to determine the aggregated weights of the criteria. Finally, ‘Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS)’ method is used to determine the suppliers' ranking in the Indian automobile industry. Six criteria and 24 sub-criteria are obtained as per recent literature and then inputs from experts. ‘Environment’ criterion came out as the most favourable criterion with a subjective weight of 0.230. The current research is one of the first such attempts to provide criteria for supplier selection in a CE environment. The developed framework would help organisations in implementing CE-based supplier selection. The identified criteria and sub-criteria would provide organisations with means to evaluate suppliers and help suppliers develop an effective and efficient CE based on the SC.     

MONEY AND INFLATION IN INDIA: EVIDENCE FROM P‐STAR MODEL

This study uses P‐star model to examine the role of money in explaining inflation in India. In particular, we compare the performance of traditional Phillips curve approach against P‐star model in forecasting inflation. Moreover, the study estimates P‐star model using the alternative measures of money such as simple sum and Divisia M3, to examine the relevance of aggregation theoretic monetary aggregates in explaining inflation. The empirical results indicate that P‐star model with real money gap has an edge over traditional Phillips curve approach in forecasting inflation. More importantly, we found that the P‐star model estimated with Divisia real money gap performs better than its simple sum counterpart. These empirical findings suggest that the changes in real money gap play a crucial role in explaining inflation in India.     

CONSISTENT ESTIMATION OF A LIMITING COVARIANCE MATRIX

This paper provides a consistent and positive semi-definite estimator of the limiting covariance matrix of a nonlinear instrumental variable estimator for a nonlinear simultaneous equation model with selectivity studied in Sapra (1989).     

An analysis of B2B ingredient co-branding relationships

The proliferation of co-branding in consumer markets has been given considerable attention in the literature, yet attention to the practice in business-to-business markets has been limited, despite the growing attention to the role of relationships in the B2B arena. In an examination of co-branding in the industrial sector, this paper discusses the use of ingredient co-branding and uses an econometric modeling approach to offer a rationale for why it occurs. The analysis provides insight into why downstream manufacturers participate in a relationship that strengthens the supplier's position in the market. We find that under the threat to the supplier of entry from a competitor whose costs are unobservable, co-branding relationships will be entered into resulting in a reduced probability of entry. This co-branding arrangement benefits both the incumbent supplier and the downstream manufacturer. The incumbent supplier benefits from the reduced probability of competitor entry, and the downstream manufacturer is rewarded with a lower price. Further, we find that the cost of the co-branded product is lower, due to a mitigation of double marginalization in a vertically-integrated solution. We examine co-branding relationships with and without advertising support and find that co-branding relationships with advertising support tend to be superior.     

Competitiveness and Efficiency of the Banking Sector and Economic Growth in Egypt

Abstract: This paper investigates the impact of financial reforms on competitiveness and production efficiency of the banking sector, as well as the short‐term and long‐term impact on economic growth, in Egypt during 1992–2007. The results suggest that the reforms have a positive and significant effect on competitiveness and production efficiency. Also, the evidence shows that state‐owned banks are generally less competitive than private banks and foreign banks are less competitive than domestic banks. The average x‐inefficiency of Egyptian banks is around 30 per cent, which is comparable to those reported for other African countries. Finally, there is evidence to suggest a significant relationship between financial bank productive efficiency and economic growth in the short run but not in the long run. Overall, the results support the argument for continuing the financial sector reform programme in Egypt.     

International equity portfolio allocations and transaction costs

In spite of the critical role of transaction cost, there are not many papers that explicitly examine its influence on international equity portfolio allocation decisions. Using bilateral cross-country equity portfolio investment data and three direct measures of transaction costs for 36 countries, we provide evidence that markets where transaction costs are lower attract greater equity portfolio investments. The results imply that future research on international equity portfolio diversification cannot afford to ignore the role of transaction costs, and policy makers, especially in emerging markets, will have to reduce transaction costs to attract higher levels of foreign equity portfolio investments.     

Comparing private and government schools in India: the devil is in the maths

Recent research shows that the gap in learning achievement between private and government schools in India can be explained away by self-selection. Analysing four rounds of panel data and distinguishing between ‘knowing’ and ‘applying’ dimensions of maths learning, I find that there is no private school advantage in the applying domain but that there is an advantage in the knowing domain.
