Abstract:
Purpose This paper aims to explore the impact of Sharīʿah-compliant stocks on other investor risk preferences beyond the risk aversion, namely, prudence and temperance. Design/methodology/approach This paper uses the non-parametric model data envelopment analysis with the shortage function as a measure of performance. The model uses three specifications considering skewness and kurtosis that describe according to expected utility theory, prudence and temperance. Findings Results show that first, efficient portfolios consist mainly of conventional stocks in the three-model specification. Second

Abstract:
This study examines the causal link between bank efficiency and bank competition. The study estimates bank competition with the Lerner index and bank cost efficiency with data envelopment analysis using annual data over the period 2001–2010. Using system generalized method of moments (system GMM) estimator, the results suggest that bank cost efficiency positively Granger-causes market power and hence causality negatively runs from bank cost efficiency to bank competition indicating that bank cost efficiency precedes bank competition. However, the reverse causality running from bank competition

Abstract:
Usual efficiency evaluation methods, such as Data Envelopment Analysis and Stochastic Frontier Estimation tend to calculate efficiency scores which are valid only at a given moment and for the units where in the sample. At most, Malmquist index determines efficiency scores for period t+1. Those drawbacks can be avoided by translating efficiency scores in terms of probabilities trough the Discriminant Analysis which enables also, to provide appropriate weightings activities of research laboratories, object of this study.

ABSTRACT Purpose: The article aims to trace the behaviour of dispersed, dominant and concentrated ownership structures in Brazil and verify which of these structures is more efficient operationally and if there is a pattern to be followed. Originality/gap/relevance/implications: Static optimisation techniques are used by data envelopment analysis (DEA) to calculate the variable ‘efficiency', a differential in relation to previous studies that consider only outcome variables as a performance indicator. The article is one of the first in the area that traces the pattern of efficiency of ownershi

Abstract:
The research interest in bank profitability and efficiency is linked to the economic situation and an important issue for policymakers is to ensure economic stability. Nevertheless, managerial decisions and the environment could play a critical role in ensuring proper and efficient allocation of the resources. The purpose of this study is to understand which are the main factors that can influence the performance and efficiency of 94 commercial listed banks from Eurozone countries through a dynamic evaluation, in the period between 2011 and 2016.

Using panel data from 11 regions (9 provinces and two cities) in the Yangtze River Economic Belt (YREB) during 2002–2017, the regional differences in and spatial characteristics of the green efficiency of water resources along the YREB were analyzed. The undesirable outputs slacks-based measure-data envelopment analysis, Malmquist index, and social network analysis models were employed. A dynamic panel using a system generalized method of moments model was established to empirically examine the main factors influencing green efficiency. The results show the following.
