This article introduces a dynamic stochastic frontier analysis (SFA) framework with unobserved heterogeneity, persistent and transient inefficiency effects, based on recent advances in the SFA literature. The newly developed model is applied sample of French crop-livestock farms. estimates provide useful insights for estimation technical efficiency scores as well associations contextual drivers...

OBJECTIVE This paper reports the measurement of technical efficiency of Tuscan Local Health Authorities and its relationship with quality and appropriateness of care. DESIGN First, a bias-corrected measure of technical efficiency was developed using the bootstrap technique applied to data envelopment analysis. Then, correlation analysis was used to investigate the relationships among technica...

 The importance of community's health followed by the consideration of endogenous growth models has led to an increase in health expenditure of countries to speed up economic growth and development. This has made the efficiency of health production function to an essential issue especially in developing countries. Based upon this, the present study with employing the stochastic frontier analysi...

In the past decade, corporate firms have globally increasingly adopted social responsibility (CSR) practices; however, so far less is known about how productivity change in presence of socially responsible and undesirable output can be evaluated. This paper develops a framework that integrates CSR dynamic by-production technology which captures transformation multiple inputs into marketed outpu...

Low productivity in agriculture is mainly due to the inability of the farmers to exploit the available technologies fully, resulting in lower efficiencies of production. The present study has estimated the technical and scale efficiencies of tomato-producing farms in Karnataka, considering different production levels and has identified the determining factors of their technical efficiency. The ...

The study was conducted in two ginger growing districts, namely Nilphamari and Khagrachari of Bangladesh during the period of 2009-10 to estimate the technical efficiency of ginger growers. The study revealed that ginger production was profitable and the average benefit cost ratio (BCR) was found 2.17. The estimated results showed that the average level of technical efficiency among the sample ...

In the standard stochastic frontier model, the two-sided error term V and the one-sided technical inefficiency error term W are assumed to be independent. In this paper, we relax this assumption by modeling the dependence between V and W using copulas. Nine copula families are considered and their parameters are estimated using maximum simulated likelihood. The best model is then selected using...

Objective: To assess the effect of patient-specific virtual reality rehearsal (PsR) before endovascular infrarenal aneurysm repair (EVAR) on technical performance and procedural errors. Background: Endovascular procedures, including EVAR, are executed in a complex multidisciplinary environment, often treating high-risk patients. Consequently, this may lead to patient harm and procedural ineffic...

One of the main drivers for determining the operating temperature of the Solar-B EIS CCDs is the possibility that substantial Charge Transfer Inefficiency may occur towards the end of the mission lifetime. The magnitude of the CTI has been discussed in several technical notes (references 1-3) and this information has been used to judge the optimum and minimum operating temperature of the CCD (r...
