Production smoothing and the shape of the cost function

Galeotti, Marzio; Guiso, Luigi; Sack, Brian; … - 1997

We present estimates of inventory models based on firm level panel data and investigate whether over-simplified specification of the production technology may account for the frequent failure to find technological incentives to smooth production in the context of the standard linear-quadratic...

Unobserved heterogeneous effects in the cost efficiency analysis of electricity distribution systems

Agrell, Per J.; Farsi, Mehdi; Filippini, Massimo; … - 2013

The purpose of this study is to analyze the cost efficiency of electricity distribution systems in order to enable regulatory authorities to establish price- or revenue cap regulation regimes. The increasing use of efficiency analysis in the last decades has raised serious concerns among...

Long-run cost functions for electricity transmission

Rosellón, Juan; Vogelsang, Ingo; Weigt, Hannes - 2010

Electricity transmission has become the pivotal industry segment for electricity restructuring. Yet, little is known about the shape of transmission cost functions. Reasons for this can be a lack of consensus about the definition of transmission output and the complexitity of the relationship...

The cost efficiency of German banks: a comparison of SFA and DEA

Koetter, Michael; Karmann, Alexander; Fiorentino, Elisabetta - 2006

We investigate the consistency of efficiency scores derived with two competing frontier methods in the financial economics literature: Stochastic Frontier and Data Envelopment Analysis. We sample 34,192 observations for all German universal banks and analyze whether efficiency measures yield...

Curvature conditions and substitution pattern among capital, energy, materials and heterogeneous labour

Koebel, Bertrand M.; Falk, Martin - 1999

This study deals with the determinants of factor demand in 27 industries of the manufacturing sector during the period 1978 to 1990. Using a quadratic cost function, six production factors are distinguished : capital, energy, three types of labour and intermediate materials. A parametric test of...

A dynamic heterogeneous labour demand model for German manufacturing

Falk, Martin; Koebel, Bertrand M. - 2000

This paper presents an application of the Generalised Error Correction Model (GECM) for heterogeneous factor demands based on the quadratic cost function. Using data for 26 West German manufacturing industries over the period 1976-1995, it turns out that less general specifications such as the...

Outsourcing of services, imported materials and the demand for heterogeneous labour : an application of a generalised box-cox function

Falk, Martin; Koebel, Bertrand M. - 2000

This paper examines the effects that purchased services and imported intermediate materials have on the labour demand for different skills in the manufacturing sector. We derive and estimate a factor demand system based on the generalised Box-Cox cost function nesting both the normalised...

Imposing and testing curvature conditions on a Box-Cox function

Koebel, Bertrand M.; Falk, Martin; Laisney, François - 2000

We present a new method for imposing and testing concavity of a cost function using asymptotic least squares, which can easily be implemented even for cost functions which are nonlinear in parameters. We provide an illustration on the basis of a (generalized) Box-Cox cost function with six...
