In this paper an attempt is made to explain the basic concept of efficiency, frontier production function, technical efficiency, deterministic frontier, and stochastic frontier. Efficiency of a firm/industry refers to its performance in the utilization of resources at its disposal and is a relative concept. Technical efficiency of a production function is defined as the maximum quantity of outp...

This report investigates 2nd Fall and 3rd Fall retention rates by Expected Family Contribution (EFC) for recent full-time, first-time (FTFT) freshman cohorts. This report serves as an update to, and extension of, prior retention by EFC reports that focused on 2 Fall Retention as the sole dependent variable. Sub-groups of interest including First Generation students, minority ethnicity students,...

Area exploration in robotics is done by number of methods some of which select next target based on shortest distance, other uses utility function and the most frequently used method is through frontier based area exploration which is boundary between explored and unexplored cells. In view of Multi robot, extra care should be taken as it may possible that two robot may collide or explore alread...

This paper extends the existing research on real estate investment trust (REIT) operating efficiencies. We estimate stochastic-frontier, panel-data models specifying a translog cost function. The specified model updates the cost frontier with new information as it becomes available over time. The model can identify frontier cost improvements, returns to scale, and cost inefficiencies over time....

in order to study the effective factors in sugar beet production, evaluation of technical, allocative and economical efficiency of sugar beet producers in bardsir city, 150 sugar beet producers were questioned by classified method. data were collected through questionnaire forms filled by producers in 2004-05. the stochastic frontier production and cost function method were used to analyze the ...

Many combinatorial optimization problems require the assignment of a set of variables in such a way that an objective function is optimized. Often, the objective function involves different criteria, and it may happen that the requirements are in conflict: assignments that are good wrt. one objective may behave badly wrt. another. An optimal solution wrt. all criteria may not exist, and either ...

In this paper we report the results from a detailed investigation of the shifts of the world production frontier function over the period 1980-2010. Analogous to a radar we implement a novel measurement approach for these shifts using nonparametrically computed productivity measures to scan the frontier shifts across the entire input-output space. The shifts of the frontier function measured in...

The paper is concerned with several kinds of stochastic frontier models whose likelihood function is not available in closed form. First, with output-oriented stochastic frontier models whose one-sided errors have a distribution other than the standard ones (exponential or half-normal). The gamma and beta distributions are leading examples. Second, with input-oriented stochastic frontier models...

the aim of this study is to investigate the context by which veterinary services may affect technical efficiency (te) of iranian dairy farms. a data envelopment analysis (dea) was applied to a random sample of 840 dairy farms from six provinces across iran to estimate regional frontier and metafrontier production functions and also to calculate corresponding te of these farms. the relationship ...
