Estimation of the production profile and metafrontier technology gap: a quantile approach
In this paper, a quantile function is suggested as an alternative description of a production technology. Since the quantile function may not share the same functional properties as the frontier function, it i...

Semiparametric smooth coefficient quantile estimation of the production profile
In this paper, quantile regression models are suggested as an alternative description of a production technology. The quantile of continuous order defines the production profile and the quantile-based individu...

A new approach to estimating the metafrontier production function based on a stochastic frontier framework
This paper proposes a new two-step stochastic frontier approach to estimate technical efficiency (TE) scores for firms in different groups adopting distinct technologies. Analogous to Battese et al. (J Prod An...

Maximum likelihood estimation of seemingly unrelated stochastic frontier regressions
In this paper, we propose the copula-based maximum likelihood (ML) approach to estimate the multiple stochastic frontier (SF) models with correlated composite errors. The motivation behind the extension to sys...

A simple closed-form approximation for the cumulative distribution function of the composite error of stochastic frontier models
This paper derives an analytic closed-form formula for the cumulative distribution function (cdf) of the composite error of the stochastic frontier analysis (SFA) model. Since the presence of a cdf is frequent...

Estimation of stochastic frontier models based on multimodel inference
In most empirical studies, once the best model has been selected according to a certain criterion, subsequent analysis is conducted conditionally on the chosen model. In other words, the uncertainty of model s...

Likelihood ratio tests for model selection of stochastic frontier models
An important issue when conducting stochastic frontier analysis is how to choose a proper parametric model, which includes choices of the functional form of the frontier function, distributions of the composit...

Cultivation Arrangements and the Cost Efficiency of Rice Farming in Taiwan
In this paper, a switching regression model is developed to analyze farmers' choice behavior and cost efficiency in field plowing arrangement in Taiwan. We find that the decision on the choice of plowing arran...

An Average Derivative Estimation of Stochastic Frontiers
This paper utilizes the average derivative estimation of Stoker (1986) and the pesudo-likelihood estimation of Fan, Li, and Weersink (1996) to estimate a semiparametric stochastic frontier regression, y = g(x)...
