The present study assesses the commercial bank profit efficiency and its relationship to banking sector competition in a rapidly growing emerging economy, India from 2009 to 2019 using stochastic frontier analysis (SFA).

Lerner indices, conventional and efficiency-adjusted, quantify competition. Two SFA models are employed to calculate alternative profit efficiency (inefficiency) scores: the two-step time-decay approach proposed by Battese and Coelli (1992) and the recently developed single-step pairwise difference estimator (PDE) by Belotti and Ilardi (2018). In the first step of the BC92 framework, profit inefficiency is calculated, and in the second step, Tobit and Fractional Regression Model (FRM) are utilized to evaluate profit inefficiency correlates. PDE concurrently solves the frontier and inefficiency equations using the maximum likelihood process.

The results suggest that foreign banks are less profit efficient than domestic equivalents, supporting the “home-field advantage” hypothesis in India. Further, increasing competition drives bank managers to make riskier lending and investment choices, decreasing bank profit efficiency. However, this effect varies depending on bank ownership and size.

Literature on the competition bank efficiency link is conspicuously scant, with a focus on technical and cost efficiency. Less is known regarding the influence of competition on bank profit efficiency. The article is one of the first to examine commercial bank profit efficiency and its relationship to banking sector competition. Additionally, the study work represents one of the first applications of the FRM presented by Papke and Wooldridge (1996) and the PDE provided by Belotti and Ilardi (2018).

The purpose of this study is to examine and review tayyiban indicators in the context of halal food production. In Islam, food produced or manufactured must be halal and tayyiban. Even though both halal and tayyiban are always mentioned together in the Quran, the halal aspect is highlighted more than tayyiban. The discussion of tayyiban’s indicators is still vague.

The study was adopted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the review of the current research which used two main journal databases, namely, Web of Science and Scopus. Accordingly, the search resulted in a total of 40 articles that can be systematically examined.

The results of review of these articles formulated five main themes: safety, nutrition, cleanliness, quality and authenticity. These five indicators are considered relevant enough in the context of halal food production to build a comprehensive tayyiban concept.

This study enriches the field of halal food research. The concept of tayyiban as a whole has been given limited attention in academic literature. At the end of this study, a number of recommendations are suggested for the reference of future scholars.

The purpose of this study is to explore the possible impact of banking market structure on the idiosyncratic risk of financially dependent firms in China.

The study analyzes firm-level data for China from 1999 to 2018 using a two-step dynamic panel system generalized method of moments (GMM).

The findings imply that bank competition lowers corporate risk, particularly among firms that are highly dependent on external funding for their financing needs. The findings are consistent with alternative indicators of competition, corporate risk, and financial dependence. The analysis of the transmission mechanism – the channel through which competition affects corporate risk – reveals that bank competition reduces corporate risk by curtailing financing constraints faced by firms.

The competition-enhancing policy should consider the optimum level of bank competition for financial and economic stability. Further research is necessary to define the “desirable” or “optimum” level of bank competition.

In China, where the banking sector is still highly concentrated, the findings of this study call for policies aimed at encouraging healthy competition among banks. Nevertheless, such a policy must also consider the extent of bank competition that is optimal for the economy, particularly for financial and economic stability.

The paper provides the first evidence of the possible linkage between bank competition and corporate risk in China.

This study aimed to identify the quality consumers expect from functional food. This study investigated the quality dimensions and indicators female consumers expect in functional food.

This study used a quantitative approach. Data were collected through a survey using a self-administered questionnaire from 149 women aged 17 years and over in the Greater Jakarta area. Data analysis consists of three stages: exploratory factor analysis (EFA), confirmatory factor analysis-structural equation modeling (CFA-SEM) and consumer expectation value analysis. Statistical Package for the Social Sciences (SPSS) and Lisrel software were used to assist the analysis.

The analysis results showed that women expect functional food products to fulfill the aspects of product presentation, product assurance, convenience, health benefits and safety and sensory characteristics. These five aspects are referred to as the expected quality dimensions. Twenty-one indicators can be used to measure the quality of functional food expected by women.

Other researchers can use this study to understand functional food female consumers' behavior. Furthermore, functional food companies can utilize it to measure consumers' expectations of their products' quality and performance.

This research is believed to be the first study to identify the dimensions of functional food quality expected by female consumers. Most existing research on the perceived quality of functional food measures functional food quality based on performance and ignored the differences in expectations between men and women.
