“…This results from the tradition for public banks to act as a kind of employment agency in countries with restricted employment opportunities. Furthermore, public banks tend to support public activities with a low level of profitability (Kumar and Gulati, ).…”

“…Public banks are not usually tested in efficiency analyses, but, in the Angolan context, public banks account for 16% of the sample, which justifies the present hypothesis. The efficiency of public banks has been examined by Kumar and Gulati (). H2: Public ownership has a positive impact on the efficiency of Angolan banks.…”
Section: Theoretical Background and Hypothesesmentioning
This article studied the technical efficiency of Angolan banks from 2005 to 2012 using a Bayesian stochastic frontier model. The intermediation approach to banking was adopted. The results revealed that Angolan banks were very efficient and that efficiency varies little among the banks analysed. Furthermore, the differences in efficiency between foreign banks, public banks, large‐sized banks and banks that belong to a local conglomerate were examined. It was concluded that the greatest efficiency was to be found in the case of foreign banks. Since size and conglomerate membership do not seem to lead to greater bank efficiency, it was proposed that Angolan policymakers should promote competition in the banking sector.

“…the bank, university, business network and microfinance institution) can be found. See, for examples, Sarrico and Dyson (2000), Mouzas (2006), Kumar and Gulati (2010), and Widiarto and Emrouznejad (2015). Note.…”
“…In academic literature, operating revenue is also used to express operational results of a company. For examples, operating revenue for measuring effectiveness of service organizations (Gronroos & Ojasalo, 2004), and operating revenue (i.e., operating income which equals net-interest income plus non-interest income in the bank industry) for measuring effectiveness of Indian public sector banks for the financial year 2006/2007 (Kumar & Gulati, 2010).…”
Section: Operating Revenue and Fortune Global 500mentioning
Feed manufacturing play a key role in agriculture development and economic growth. The present paper elucidates an operating revenue-DEA efficiency (OR-DEAE) matrix to evaluate both big and strong aspects of feed enterprises in China based on the evaluation measure of Fortune Global 500 and a Data Envelopment Analysis (DEA) method, i.e., super-efficiency CCR model, in order to achieve a healthy and sustainable development in feed manufacturing. Results show that there is a big difference between the performances of feed companies in China. Most of the feed companies are in the question mark quadrant or dog quadrant of the OR-DEAE matrix, showing that their operation levels are relatively low. Only two benchmarking companies were in the star quadrant which reflects they have both big and strong capability. We therefore provide several suggestions for the backward companies to improve their performance.
“…Unfortunately, to construct efficiency frontier with high quality is not so easy and it is still a hot issue in research. Kumar and Gulati [7] use linear programming in 2010 to construct efficiency frontier for 27 public sector banks operating in India and find out that high efficiency does not necessarily create high effectiveness and performance.…”
Financial crises, like Asian financial crisis in 1997 and credit crunch from USA in 2007, have huge influence worldwide. For the importance and uniqueness of China's stock market, it is interesting and attractive to research it under influence of financial crises. The purpose for this research is to find out the influence of financial crises on Chinese stock market and focus on efficiency frontier. For research methodology, the efficiency frontiers are built using cross-sectional data through linear programming with an optimization model for different periods for Chinese stock markets portfolios and for a portfolio from Chinese, UK and USA stock markets together under current financial crisis. This research finds out that Chinese stock markets have a positive risk return trade off and it varies under the influence of financial crises; the investment efficiency in Chinese stock markets are relative good currently and if further diversified with western markets, higher investment efficiency can be achieved. The implication for this paper is to offer a suitable method to construct Chinese stock market efficiency frontier, and to improve investment efficiency through further diversification. This paper enjoys the originality that it perhaps is the first paper to build Chinese stock market efficiency frontier through linear programming.
