This study aims to investigate the efficiency of Indian commercial banks from 2002 to 2018 using the stochastic frontier analysis.

This study uses the parametric approach of the stochastic frontier to examine the technical efficiency of banks acknowledging exogenous shocks, omitted variables and measurement errors, filling a gap in the existing financial literature. The scope of this study was constrained to 71 scheduled commercial banks to make it manageable and productive with 1,036 observations.

The results show that the mean technical efficiency of new private banks remained constant at 92.7% during the study period because of technology diffusion in banking systems. The technical efficiency of the nationalized, old private and foreign banks has enhanced over the period because of the efficient utilization of various innovative information technology services such as mobile banking, cheque truncation system, magnetic ink character recognition. However, the foreign banks are still laggards with a mean technical efficiency of 81.7%. The empirical findings suggest that new private sector banks depict higher efficiency than nationalized, old private and foreign banks.

This study’s sample represents all categories of banks (public, private and foreign) including the banks that merged or consolidated during the period of study. To achieve the desired results, the authors incorporate the consolidated and merged banks in their data set. Further, the authors excluded all scheduled small finance banks and scheduled payment banks from their analysis, as these entities commenced operations post-2015. Additionally, the authors also excluded regional rural banks because of their distinct mandate aimed at servicing the rural populace and agricultural sector.

This study contributes to the literature on the performance of conventional banks in general and emerging markets, in particular, using the most recent data and covering a relatively long period using the stochastic frontier approach.

This study aims to explore the global issues of impulse buying, compulsive purchasing and materialism. It examines how materialism relates to self-esteem and the tendencies for impulsive and compulsive buying. In addition, the study delves into the impact of religiosity on self-esteem and materialistic values in an Islamic country.

Enumerators visited universities, distributing 415 questionnaires and receiving 397 in return. Due to the unavailability of a sample frame for the target population, the study used nonprobability sampling for statistical analysis, which included assessments of normality, reliability, validity and bootstrapping for the structural model, the researchers used Smart PLS.

The study confirmed 13 hypotheses while rejecting four. The unsupported hypotheses are: (i) materialism negatively impacts impulsive purchasing behavior, (ii) impulsive purchasing does not mediate the relationship between materialism and compulsive purchasing, (iii) materialism does not mediate the relationship between religiosity and impulsive purchasing and (iv) in an Islamic country, neither materialism nor impulsive purchasing significantly mediates the relationship between religiosity and compulsive purchasing.

This study was conducted in a city within a developing Islamic nation, focusing on college students. It suggests that future research could include more cities, a diverse population segments and multicultural perspectives. The research primarily examined the direct relationships between religiosity and factors such as self-esteem, materialism and impulsive purchasing. Future studies could explore religiosity as a mediating factor. This study highlights that materialism (M), impulsive buying (IB) and compulsive buying (CB) are not only closely interconnected but also adversely affect individual, family and societal well-being, raising global concerns. While occasional impulsive behavior is common among individuals in Islamic nations, repeated indulgences in the same behavior could lead to an obsession with excessive purchasing.

This study holds significant implications for consumers and retailers. Excessive and unnecessary spending can increase financial burden and adversely affect family welfare. Often, families and acquaintances inadvertently teach children to engage in extreme purchasing behaviors. To combat this, families and religious leaders should educate individuals about the detrimental effects of impulsive and compulsive purchasing. In addition, colleges and other institutions should organize seminars and workshops to address these issues. Retailers, whose sales largely depend on impulsive and compulsive consumers, should employ interpersonal influencers and brand advocates to connect with this customer segment effectively.

This study examined the relationship between religiosity, materialism, self-esteem and impulsive and compulsive purchasing behaviors. This study thoroughly tested 17 hypotheses, encompassing direct, mediating and multimediating relationships. The findings reveal that materialism’s impact on impulsive behavior is negligible compared to previous research, corroborating the findings presented in the cited literature.

Although literature abounds on lean sustainability (LS), its contributions to manufacturing industries’ triple bottom line performance (TBLP) through top management commitment (TMC) remain scanty. This research explores the mediating role of TMC in the nexus between LS and TBLP.

Given the study’s quantitative focus, the causal design was utilised. The structured questionnaire, a survey instrument, was used to gather primary data from 285 manufacturing organisations in Ghana, a developing country. Data analysis was done with structural equation modelling.

It was found that LS and TMC positively influence TBLP, whereas TMC partially mediates the connection between LS and TBLP of Ghanaian manufacturing organisations.

The study concentrates on Ghana’s manufacturing industry and embraces the stakeholder theory and quantitative methods.

This research underlines why top managers must prioritise investment in LS to promote sustainable development and attain their organisations’ TBLP targets. The study also provides key insights for top managers to consistently commit enormous resources towards developing lean practices, contributing favourably to TBLP. By establishing the interplay among LS, TMC and TBLP, manufacturing practitioners and researchers can further advance new strategies to address the growing sustainability concerns and achieve higher economic, social and environmental performance.

The study’s originality lies in analysing the mediation effect of TMC on the linkage between LS and TBLP in a developing economy where manufacturing organisations are continuously exposed to resource and waste management problems and lack adequate commitments from top managers towards sustainability initiatives. It is also the first to establish relationships between top management commitment and TBLP in the manufacturing industries of developing economies, concentrating on Ghana.
