RePub, Erasmus University RepositoryTrade liberalization and the allocation over domestic and foreign supplies: a case study for Spanish manufacturing

The purpose of the present paper is to investigate whether Spain's accession
to the European Union in 1986 caused a structural break in the allocation of total supplies of manufactures over domestic and foreign supplies. To that end we use the homogeneity-constrained Almost Ideal Demand System to
specify the long-run equilibrium relationships between the shares in total supplies and total real demand and relative prices and a first-order error correction mechanism in order to describe the adjustment process to equilibrium. Using a formal statistical test, it turns out that a
structural break actually occurred and led to a rather sharp decrease in the share of Spain and an increase in the shares of the other members of the European Union.A dynamic specification of an AIDS import allocation model

In this paper we use the first-order autoregressive scheme in order to introduce dynamics into the AIDS model. We also consider the theoretical restrictions of additivity, homogeneity and symmetry, and use two different specifications of the covariance matrix. We estimate the models using import allocation data for the UK 1952-1979 of five EEC countries and test different specifications against each other.On Bayesian and non-Bayesian estimation of a two-level CES production function for the Dutch manufacturing sector
http://repub.eur.nl/pub/15310/
Sat, 01 Jan 1977 00:00:01 GMT<div>R. Harkema</div><div>S. van der Loeff</div>
In this paper maximum-likelihood estimates of the parameters of the two-level CES function, obtained by direct estimation of this function, are given. In addition the authors propose to show how a Bayesian analysis may help to find a solution to the difficulties related with, but not specific to, this particular estimation problem. It is shown that numerical integration of the posterior distribution may give an indication as to which parameter has to be pinpointed and at which value when multi-collinearity precludes unconditional maximization of the likelihood. It is suspected that this approach has a wider field of application.A note on aggregation of CES-type production functions

In this note we shall be concerned with the aggregation of the constant elasticity of substitution (CES) type of production function. In particular we will derive the error made by using the arithmetic averages as they are usually published, rather than the theoretically required averages.
