Nonparametric Estimation of Higher-Order Moments of Technical Efficiency
نویسندگان
چکیده
In this paper nonparametric techniques are used to estimate higher-order moments of technical efficiency. The procedures given in this paper allow the moments to be estimated with relative ease, while at the same not requiring restrictive assumptions on the distribution of inefficiency. The results given by these estimates will allow researchers to gain additional information on the inefficiency of a given firm. As an empirical example, the estimators are applied to a data set examining labor efficiencies of 17 railway companies over a period of 14 years.

The purpose of this article was to estimate the effect of higher education on total productivity changes and technical efficiency in the 4-digit classification code of ISIC in Iran during the period of 1994-04. In this regard, a two-way stage approach was used. In the first stage, Malmquist Productivity Index (MPI) and technical efficiency index by Data Envelopment Analysis (DEA) and Stochastic...

متن کاملPseudo Zernike Moment-based Multi-frame Super Resolution
The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
متن کاملStochastic Nonparametric Envelopment of Data: Frontier Estimation Subject to Shape Constraints
Literature of productive efficiency analysis is currently divided between two main paradigms: the parametric Stochastic Frontier Analysis (SFA) and the deterministic, nonparametric Data Envelopment Analysis (DEA). This paper develops a new encompassing framework that melds the SFA-style stochastic composite error term to the DEA-type nonparametric frontier that satisfies monotonicity and concav...
متن کاملNonparametric estimating equations based on a penalized information criterion
It has recently been observed that, given the mean-variance relation, one can improve on the accuracy of the quasi-likelihood estimator by the adaptive estimator based on the estimation of the higher moments. The estimation of such moments is usually unstable, however, and consequently only for large samples does the improvement become evident. The author proposes a nonparametric estimating equ...
