Estimating allocative efficiency in port authorities with demand uncertainty
Hidalgo, Soraya; Núñez-Sánchez, Ramón - Volkswirtschaftliche Fakultät, … - 2012
This paper aims to analyse the impact of port demand variability on the allocative efficiency of Spanish port … different approaches: error components approach and parametric approach. We model the variability of port demand from the … that port authorities have excess capacity and their resources are misallocated. Finally we establish that the allocative …

Production Efficiency and Diversification in Mexican Coffee-Producing Districts
Vedenov, Dmitry V.; Houston, Jack E.; Cardenas, Gabriela - In: Journal of Agricultural and Applied Economics 39 (2007) 03
Coffee production system is analyzed for 24 municipios (districts) in Veracruz, Mexico, from 1997 to 2002. A stochastic frontier approach is used to estimate an input distance function and to evaluate production efficiency. Results show the production process to be stable over time despite...

Technical and Environmental efficiencies and Best Management Practices in Agriculture
Tamini, Lota D.; Larue, Bruno - Volkswirtschaftliche Fakultät, … - 2009
An input distance function (IDF) is estimated to empirically evaluate and analyze the technical and environmental efficiencies of 210 farms located in the Chaudière watershed (Quebec), where water quality problems are particularly acute because of the production of undesirable outputs that are...

The Measurement Of Efficiency Where There Are Multiple Outputs
Whiteman, John L. - Centre of Policy Studies and Impact Project (COPS), … - 1999
This paper is motivated by the empirical observation that in many studies the elasticity of output with respect to labour is often negative and/or insignificant. The present study applies multiple output models to estimate the technical efficiency of enterprises in the international electricity,...

A Multiple Output Stochastic Ray Frontier Production Model
Löthgren, Mickael - Economics Institute for Research (SIR), … - 1997
This paper proposes an approach to specify and estimate multiple input, multiple output production frontiers and technical efficiency using a stochastic ray frontier production model A possible model extension is to incorporate a technical efficiency effects model to allow estimation of the...

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.

Unobserved Heterogeneity and International Benchmarking in Public Trasport
Cullmann, Astrid; Farsi, Mehdi; Massimo, Filippini - USI Università della Svizzera italiana - 2009
We analyze the technical efficiency of German and Swiss urban public transport companies by means of SFA. In transport networks we might face different network structures or complexities, not observed, but influencing the production process. The unobserved factors are typically modeled as...
