Lewbel, Arthur - Department of Economics, Boston College - 2007

Shape invariance is a property of demand functions that is convenient for semiparametric demand modelling. All known shape invariant demands are derived from utility functions that, up to monotonic transformation, are called IB/ESE (independent of base - equivalence scale exact) utility...

On the Restrictiveness of Separability: The Significance of Energy in German Manufacturing

Frondel, Manuel; Schmidt, Christoph M. - 2006

Any researcher would certainly agree with Hamermesh?s (1993:34) intuition about separability that the ease of substitution between any two production factors should be unaffected by a third factor that is separable from the others. This paper emphasizes that such a notion of separability needs...

Measuring Scale Economies in a Heterogeneous Industry: The Case of European Settlement Institutions

van Cayseele, Patrick; Wuyts, Christophe - 2006

We examine whether the European settlement institutions are technically efficient. This is done by means of estimating a translog cost function, and investigating whether scale economies are fully exploited. Since the sample is quite heterogeneous, fixed effects regression is introduced. From...

Estimating the marginal costs of airport operation by using multivariate time series model with correlated error terms

Link, Heike; Götze, Wolfgang; Himanen, Veli - Wirtschaftswissenschaftliche Fakultät, Westfälische … - 2006

The research presented in this paper was motivated by the central role of infrastructure charing in European transport policy. It is dedicated to the question whether and to what extent marginal infrastructure costs of airports, e.g. the marginal costs of maintaining, renewing and operating...

Tricks With Hicks: The EASI Demand System

Lewbel, Arthur; Pendakur, Krishna - Department of Economics, Boston College - 2006

We invent Implicit Marshallian Demands, a new type of demand function that combines desirable features of Hicksian and Marshallian demand functions. We propose and estimate the Exact Affine Stone Index (EASI) Implicit Marshallian Demand system. Like the Almost Ideal Demand (AID) system, EASI...

Stochastic frontier models

Wang, Hung-Jen - Volkswirtschaftliche Fakultät, … - 2006

The stochastic frontier model was first proposed in the context of production function estimation to account for the effect of technical inefficiency. The inefficiency causes actual output to fall below the potential level (that is, the production frontier) and also raises production cost above...

VOCs’s Cost functions in the Design of Emission Abatement Strategies

Mariam, Yohannes; Barre, Mike - Volkswirtschaftliche Fakultät, … - 1996

. Cost optimization requires the availability of abatement cost functions. The current study presents methodologies to derive … cost functions for VOCs in Canada. Abatement cost functions are mathematical representations of discrete emission reduction … points and their corresponding total annualized cost. The objective for which cost functions are derived determines the …
