A spreading method to improve efficiency prediction.

Dios-Palomares, Rafaela; Paz, Jose Miguel Martínez - Centro de Estudios Andaluces, Government of Andalusia - 2004

In efficiency analysis by means of a stochastic frontier production function, the composite error variable includes the inefficiency component. For this reason, individual prediction cannot be made directly from an estimation of the error in the model. In order to solve this problem, Jondrow et...

Statistical Inference in Nonparametric Frontier Models: The State of the Art

Simar, Léopold; Wilson, Paul - In: Journal of Productivity Analysis 13 (2000) 1, pp. 49-78

Efficiency scores of firms are measured by their distance to an estimated production frontier. The economic literature proposes several nonparametric frontier estimators based on the idea of enveloping the data (FDH and DEA-type estimators). Many have claimed that FDH and DEA techniques are...

Generalized Stochastic Frontier Production Models

Löthgren, Mickael - Economics Institute for Research (SIR), … - 1996

This paper proposes a generalization of the single output stochastic production frontier model. The generalization allows estimation of production frontiers and distance functions (technical efficiency) for multiple output technologies using cross section or panel data on inputs and outputs.

A Frontier Model for Landscape Ecology: The Tapir in Honduras

Flesher, Kevin; Ley, Eduardo - EconWPA - 1995

We borrow a frontier specification from the econometrics literature to make inferences about the tolerance of the tapir to human settlements. We estimate the width of an invisible band surrounding human settlements which would act as a frontier or exclusion zone to the tapir to be around 290 meters.
