SLACK AND NET TECHNICAL EFFICIENCY MEASUREMENT: A BOOTSTRAP APPROACH

Slack and Net Technical Efficiency Measurement: a Bootstrap Approach

A Technical Approach to Net Neutrality

A recent statement by AT&T CEO Ed Whitacre sparked considerable fear in the public that the Internet may not be open any more: the ISPs dictate which sites/applications flourish and which flounder. The statement triggered the heated debate on net neutrality and ignited the battle to enact net neutrality legislation. However, by the date of writing, all attempts to pass net neutrality laws have ...

New Technical Efficiency Estimates with Improved Bootstrap Confidence Interval Coverage

Bootstrap confidence intervals on fixed-effects efficiency estimates from finite-sample panel data models exhibit low coverage probabilities, because the traditional estimate involves a "max" operator that induces a finite sample bias. Attempts to bootstrap confidence intervals for the traditional estimate have focused on correcting bias. Rather than addressing this bias at the bootstrap stage,...

Slack-Based Measurement with Rough Data

Rough data envelopment analysis (RDEA) evaluates the performance of the decision making units (DMUs) under rough uncertainty assumption. In this paper, new discussion regarding RDEA is extended. The RSBM model is proposed by integrating SBM model and rough set theory. The process of reaching solution is presented and this model is applied to efficiency evaluation of the DMUs with uncertain ...

Technical Efficiency of Nigerian Insurance Companies: A Data Envelopment Analysis and Latent Growth Curve Modelling Approach

The main purpose of this paper is to investigate the performance of Nigerian insurance companies using Data Envelopment Analysis (DEA). Because of the unavailability of the required data, the study is limited to ten Nigerian insurance companies for the period of five years from 2008 to 2012. The input employed were commission expenses and management expenses, while premium and investment income...
