New types of characterization of Pareto efficiency based on data envelopment analysis are extended here in several new directions involving allocative efficiency and stochastic filtering methods.

‎in this paper allocating a fixed resource for producing ‎finite projects in order to obtaining a desired level of‎ ‎efficiency will be discussed‎. ‎note that it is assumed that a ‎vector of limited sources is at hand‎. ‎this vector of resources can‎ ‎be contained human resource‎, ‎budget‎, ‎equipment‎, ‎and facilities‎. ‎in ‎any firm there exist different suggestions from subunits for ‎running...

in this current study a generalized super-efficiency model is first proposed for ranking extreme efficient decision making units (dmus) in stochastic data envelopment analysis (dea) and then, a deterministic (crisp) equivalent form of the stochastic generalized super-efficiency model is presented. it is shown that this deterministic model can be converted to a quadratic programming model. so fa...

This paper aims to assess the environmental efficiency of refineries in the public sector with emphasis on generated effluents and water consumption in the production process. In order to conduct this research, the addressed method was quantitative with a qualitative approach to the environmental aspects of controllable and uncontrollable variables imp...

Abstract We introduce methods to apply stochastic frontier analysis (SFA) financial assets as an alternative data envelopment analysis, because SFA allows us fit a with noisy data. In contrast conventional SFA, we wish deal estimation risk, heteroscedasticity in noise and inefficiency terms. investigate measurement error the risk return measures using simulation–extrapolation method develop res...

While it is widely believed that advertising media spending may not be optimal or efficient, it is not easy to measure the inefficiency, or the potential loss of sales due to inefficient ad spending. Advertising media spending efficiency needs to be measured and benchmarked. Here two approaches are presented and compared to evaluate top 100 advertisers’ media spending inefficiency. The two meth...

The efficiency of social housing providers is a contentious issue. In the Netherlands, there is a widespread belief that housing corporations have substantial potential for efficiency improvements. A related question is whether scale influences efficiency, since recent decades have shown a trend of mergers among corporations. This paper offers a framework to assess the effects of scale and merg...
