Examining the determinants of efficiency using a latent class stochastic frontier model

Examining the Inefficiency of Transit Systems Using Latent Class Stochastic Frontier Models

Managerial performance and cost efficiency of Japanese local public hospitals: a latent class stochastic frontier model.

The paper explores the link between managerial performance and cost efficiency of 617 Japanese general local public hospitals in 1999-2007. Treating managerial performance as unobservable heterogeneity, the paper employs a panel data stochastic cost frontier model with latent classes. Financial parameters associated with better managerial performance are found to be positively significant in ex...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Properties of Technical Efficiency Estimators in the Stochastic Frontier Model

The estimation of frontier cost and production functions has been given impetus by the introduction of the stochastic frontier.’ This model is distinguished by a disturbance term composed of two parts a one-sided component, non-positive for production functions and non-negative for cost functions, representing the degree of inefficiency, and a symmetric component representing the usual statisti...
