The home market effect in the Spanish industry, 1965-1995

This study was intended to identify empirically the existence of the home market effect (HME) in Spanish manufacturing industry, a case which shows some incipient evidence in very early stages of development, and an increasing relevance of this phenomenon over time. Our empirical test is carried out with 17 regions between 1965 and 1995, and lends support to the hypothesis of the existence of the HME in five of the nine industries analysed. These results are obtained using a specification in line with the traditional one but new in the sense that it is defined in proportions instead of levels; this approach has conceptual advantages because it is a relative one, like the definition of HME itself

External economies as a mechanism of agglomeration in EU manufacturing

International audienceProductive externalities are significant determinants of agglomeration, not deeply studied at the industry and international level. We analyse the impact on productivity growth of technological externalities, both inter- and intraindustry, national or international, at the industry level for the European Union (EU) countries and the period 1995-2002. The results confirm the advisability of considering international externalities when countries are takes as regions, whose omission underestimates national spillovers. Together with national endowments and a central geographical position, the growth of productivity is encouraged by national and international specialization as a general result; moreover, it is fuelled by stronger interindustry spillovers and productive diversification, a result more evident for high technology industries, while lower technology industries are more sensitive to the omission of international externalities. Economic integration seems to be relevant, because supranational regions with less friction for goods and factor movements are more likely to take advantage of external economies as a mechanism of productivity growth and agglomeration

Asymptotic Behaviour of Inhomogeneous String Cosmologies

The asymptotic behaviour at late times of inhomogeneous axion-dilaton cosmologies is investigated. The space-times considered here admit two abelian space-like Killing vectors. These space-times evolve towards an anisotropic universe containing gravitational radiation. Furthermore, a peeling-off behaviour of the Weyl tensor and the antisymmetric tensor field strength is found. The relation to the pre-big-bang scenario is briefly discussed.Comment: 15 pages, Late

Zonal flows and long-distance correlations during the formation of the edge shear layer in the TJ-II stellarator

A theoretical interpretation is given for the observed long-distance correlations in potential fluctuations in TJ-II. The value of the correlation increases above the critical point of the transition for the emergence of the plasma edge shear flow layer. Mean (i.e. surface averaged, zero-frequency) sheared flows cannot account for the experimental results. A model consisting of four envelope equations for the fluctuation level, the mean flow shear, the zonal flow amplitude shear, and the averaged pressure gradient is proposed. It is shown that the presence of zonal flows is essential to reproduce the main features of the experimental observations.Comment: 19 pages, 7 figure

Space-times admitting a three-dimensional conformal group

Perfect fluid space-times admitting a three-dimensional Lie group of conformal motions containing a two-dimensional Abelian Lie subgroup of isometries are studied. Demanding that the conformal Killing vector be proper (i.e., not homothetic nor Killing), all such space-times are classified according to the structure of their corresponding three-dimensional conformal Lie group and the nature of their corresponding orbits (that are assumed to be non-null). Each metric is then explicitly displayed in coordinates adapted to the symmetry vectors. Attention is then restricted to the diagonal case, and exact perfect fluid solutions are obtained in both the cases in which the fluid four-velocity is tangential or orthogonal to the conformal orbits, as well as in the more general "tilting" case.Comment: Latex 34 page
