    Este artículo estudia el papel que desempeña la Teoría de juegos en la nueva Economía Política institucional. Tras presentar los rasgos principales del modelo de optimización neoclásica y de la Teoría de juegos, se centra en los juegos de coordinación y en los juegos repetidos y muestra cómo estos juegos pueden aplicarse a problemas relevantes de la moderna Economía institucional.This paper studies the role of game theory in new institucional political economy. After dicussing the main features of both the neoclassical optimization model and game theory, it deals with coordination and repeated games and shows how these games can be applied to relevant problems of modern institutional economics

    Nuevos enfoques en la historia económica de España y de América Latina. Homenaje a Robert W. Fogel y Douglas C. North, Premios Nobel de Economía 1993Editada en la Universidad Carlos IIIA partir de la tesis de Horwitz sobre la industrialización y el derecho de daños, este artículo estudia el derecho de accidentes y la regulación pública de la industria en la España del siglo XIX. Muestra que tanto el sistema del common law como los sistemas legales continentales ayudaron al desarrollo de la industria y los ferrocarriles la aplicación de la regla de responsabilidad por culpa y una regulación administrativa favorable. Concluye el artículo con una breve discusión sobre la teoría de la búsqueda de rentas y la ideología como argumentos que explican estos cambios legales.Beginning with Horwitz thesis on industrialization and tort law, this paper studies the law of accidents and the public regulation of industry in XIXth century Spain. It shows that both the common law and the continental legal systems helped to develop industry and railroads through the negligence rule and positive public regulation. The paper concludes with a short discussion of rent seeking and ideology as arguments that can explain these changes in the legal tradition.Publicad

    Low-frequency phonons in carbon nanotubes: A continuum approach

    7 págs.; 6 figs.; 2 apéndices ; PACS number s : 68.65. k, 63.22. mLow-frequency phonons in carbon nanotubes are studied using a continuum model which allows consideration of an arbitrary wall thickness for the nanotube. Phonon dispersion relations are calculated for two archetypal examples of carbon nanotubes, the (5,5) and (10,10) tubes. The dependence of the radial breathing mode frequency at Γ on the inverse nanotube diameter is verified within this model; furthermore, we prove it to hold for all pure modes within the thin-shell approximation. The effect of the nanotube wall thickness on the eigenfrequencies of carbon nanotubes is also analyzed, and a criterion to fix this parameter within a continuum model is presented. We compare our results to other continuum approaches, and show that by choosing the appropriate parameters, excellent agreement with recent first-principles calculations can be achieved. © 2006 The American Physical Society.This work has been partly supported by the Spanish DGES Grant No. MAT 2002-04540-C05-03 and the Vicerrectorado de Relaciones Internacionales UCLM.Peer Reviewe

    Squeezing enhancement by competing nonlinearities: Almost perfect squeezing without instabilities

    4 págs.; 3 figs.; PACS number~s!: 42.50.Dv, 42.50.Lc, 42.65.KyThe competition between the χ(2) nonlinearity of a resonant second-harmonic-generation (SHG) system and an added χ(3) nonlinearity shifts the Hopf bifurcation of the standard SHG towards higher photon numbers eventually completely stabilizing the system. Remarkably, perfect squeezing survives the stabilization. Two important consequences are discussed, namely, efficient bright squeezing generation and strong suppression of the excess noise which, for parameters corresponding to an experiment reported in the literature, can be reduced by two orders of magnitude without diminishing the squeezing. Possible experimental implementations are finally discussed. ©1997 American Physical SocietyThis work was supported in part by Project No. TIC95- 0563-C05-03 (CICYT, Spain).Peer Reviewe
