Model uncertainty and efficiency measurement in stochastic frontier analysis with generalized errors
Abstract Advanced efficiency measurement methods usually fall within Stochastic Frontier Analysis (SFA), Data Envelopment (DEA), or their derivatives. Although SFA has some theoretical advantages, it been criticized for relying on arbitrary and potentially restrictive assumptions about model specification. One strand of the literature suggests use nonparametric SF models to cope with issue. We ...
Frontier techniques have been used to measure healthcare provider efficiency in hundreds of published studies. Although these methods have the potential to be useful to decision makers, their utility is limited by both methodological questions concerning their application. The aim of this paper is to search articles applying combined data envelopment analysis (DEA) and stochastic frontier analy...
This paper investigates cost and profit efficiency of German hospitals. More specifically, it deals with the question how hospital efficiency varies with ownership, patient structure, and other exogenous factors, which are neither inputs nor outputs of the production process. We conduct a Stochastic Frontier Analysis (SFA) on a multifaceted administrative German dataset combined with the balanc...

Purpose This study aims to analyse the efficiency effects of institutional distance on Chinese outward foreign direct investment (FDI) in Africa. Design/methodology/approach The utilised true fixed-effect stochastic frontier analysis (SFA) model. Data from 2003 2016 (14 years) were acquired 42 targeted African countries, which are included analysis. Findings results reveal that FDI flow can be ...
Background: Health Sector is considered as one of the most important service subsystems and at the same time a segment of social security and development indices. Among this, hospitals are mentioned as the greatest and most costly operational unit of health sector that need to apply economical and performance analysis to access optimal use of facilities and resources. This study is co...
This article basically tries to examine the relationship between efficiency and risk in Iranian banking system. The scholars here simply employ two approaches, i.e. parametric (economic-based) approach, and non-parametric (mathematical optimization-based) approach, to assess the efficiency, rank the banks, select the optimal model and at last, identify the impact of credit, operational and liqu...
INTRODUCTION Hospitals are the most expensive health services provider in the world. Therefore, the evaluation of their performance can be used to reduce costs. The aim of this study was to determine the efficiency of the hospitals at the Kurdistan University of Medical Sciences using stochastic frontier analysis (SFA). METHODS This was a cross-sectional and retrospective study that assessed ...
