The paper also compares the observed banks in terms of total factor productivity growth for the aforementioned period. The results obtained from the exercise indicate improvement in mean technical efficiency scores in 2004–05 relative to the previous four years. However, mean technical efficiency showed a declined in the next year. The observed private sector banks exhibited higher mean technical efficiency relative to the observed public sector banks for 2000–01 to 2003–04 (and 2005–06) while the reverse is true for 2004–05. The public sector banks, however, exhibit higher mean scale efficiency relative to the observed private sector banks. In so far as total factor productivity growth is concerned, the observed public sector commercial banks exhibited relatively higher Malmquist TFP growth than the observed private sector banks. However, the commercial banks, across ownership groups, exhibited negative mean total factor productivity growth. The negative growth (in real terms) may be the result of emphasis laid on off balance sheet activities on the part of the commercial banks

This article considers the three alternative paradigms—Value at Risk (VaR), Expected Shortfall (ES) and Expected Excess Loss (EEL) that may be used to determine the regulatory capital. The study also articulates the methodology for dealing with the granularity problem. Furthermore, it outlines the Indian banking sector scenario in respect of capital adequacy for the period ...

For this, single stage and Malmquist DEA have been used. The paper excludes the foreign commercial banks from the discussion. The period of analysis is 2001-02 to 2004-05. Thirty-eight Indian commercial banks have been included in the analysis. The results obtained from the exercise indicate substantial fluctuations in mean technical efficiency scores for the observed years. Further, the mean technical efficiency scores of the observed public sector commercial banks is considerably lower than the observed private sector banks. Both under constant and variable returns to scale, the overall mean technical efficiency score of the observed public sector banks is about 85 per cent of the observed private sector banks. In so far as total factor productivity growth is concerned, the observed commercial banks exhibit negative growth. A comparison of results across bank categories indicate that the observed public sector commercial banks exhibited marginally higher Malmquist TFP Index than the observed private sector banks.

However, managerial ability is the cognitive capability which is not directly observable/measurable. In this article, an indirect estimate of managerial ability under a three-stage approach for 20 Indian general insurance companies based on 120 firm-year observations spread over the period 2012–2013 to 2017–2018 is provided. The three-stage estimation method for the measurement of firm-specific managerial ability includes data envelopment analysis (DEA)-goal programming, pooled regression, residual of the pooled regression, Ordinary Least Squares, and General Additive Model regression. Unlike other studies, in this study, DEA-goal programming method is considered to improve discriminatory power for proper classification of the Indian general insurance companies. The results indicate that the influence is statistically significant.

This paper makes use of two nonparametric methodsthe Free Disposal Hull approach (FDH) and the Data Envelopment approach for construction of the cost frontier for efficiency measurement. In the FDH approach, we take segments of the cost frontier as the benchmark. In the DEA approach, the authors take a linear version of the entire frontier as the benchmark. As per the FDH results, observed public sector commercial banks exhibit higher mean efficiency scores (when the year-wise figures are averaged) than the observed private sector banks when net interest margin or non-interest income are taken as the output indicators. However, if loan is taken as the output indicator, the mean efficiency score of the observed private sector banks is higher than the observed public sector banks. In terms of DEA, the observed private sector commercial banks have higher mean cost, technical and cost efficiencies than the observed public sector commercial banks. In case of allocative efficiency, however, the results indicate fluctuations in efficiency scores across the commercial bank groups when loan is taken as the output indicator. Test of significance has been carried out to examine if the mean cost efficiencies of the two bank groups are significantly different across bank groups. The results are positive for both FDH and DEA.

The present study evaluates the efficiency performance of fifteen Indian general insurance companies for the period 2011/12-2016/17 using a robust nonparametric approach. The study also seeks to explain efficiency by considering the influence of environmental variables on the efficiency scores. The results indicate that efficiency is positively related to ownership, insurer age, market share, and return on equity but negatively related to size.

The present paper employs Bootstrap Data Envelopment Analysis (DEA) for evaluating the performance of a few sectoral mutual fund schemes for the second half of 2010. The study uses input-oriented, output-oriented and graph hyperbolic measures of efficiency for the purpose of bootstrap DEA analysis. The computation is made in “R”.

The study applied data envelopment analysis for estimating labour-use efficiency. In the second stage, the study applied censored Tobit regression for determining the impact of several contextual variables on efficiency. The study reveals that the mean labour-use efficiency score of the selected branches is 76% when averaged for the in-sample branches over the observation period. Results of the Tobit regression identified cluster 2 and total business of the branches as the significant factors for determining efficiency and the number of employees as a significant variable influencing inefficiency.

The present paper makes use of non-parametric endogenous benchmarking to evaluate the performance of 16 sectoral mutual fund schemes based on observations for the period July-December 2010. The study uses both the reward to variability and reward to lower partial moment framework for the measurement of pure technical efficiency and scale efficiency of the in-sample mutual fund schemes. The results indicate that 3 schemes achieved technical efficiency in the reward to variability framework while 2 schemes were found to be efficient if one uses the reward to lower partial moment framework.

From an impact-driven development programme, microfinance institutions (MFIs) today emerged as commercially oriented profit-making entities. In addition to bringing their commercial and social objectives into balance, MFIs today are striving for efficient level of operation. Efficiency in the level of operation of MFIs allows them to remain competitive and attain financial sustainability. However, it is also imperative for MFIs to remain socially committed towards the ultimate mission of reaching the poorest at the bottom of the pyramid. Hence, it is of research interest to see the trade-off between MFIs’ social objective of spreading outreach and at the same time remaining financially sustainable. Against this backdrop, this article is devoted to study the potential impact of competition and commercialisation on efficiency of MFIs in India and Banglad...

In the first stage, a robust bootstrap approach is followed for the estimation of technical efficiency scores of 16 in-sample public and private sector general insurance companies. In the second stage, the impact of solvency on the efficiency of the insurers has been considered via truncated regression. The results point out a statistically significant relationship between input/output oriented efficiency and solvency ratio.

A major weakness of the static framework is that the efficiency results are not inter-temporally comparable. In order to overcome this problem, the present study uses a dynamic slacks-based DEA model proposed by Tone and Tsutsui (2010) for performance evaluation of 15 in-sample life insurance companies for a seven-year period (2005–2006 to 2011–2012). The unique selling point (USP) of the present approach is that unlike the conventional static DEA models, the present framework, by using a link variable, connects the observed years and thereby creates a common benchmark. The results reveal significant fluctuations in mean technical efficiency over the period of observation.
