A Quantitative Exploration of the Golden Age of European Growth
Income per capita in some Western European countries more than tripled in the two and a half decades that followed World War II. The literature has identified several factors behind this outstanding growth episode, specifically; structural change associated with large migrations from agriculture to nonagricultural sectors, the Marshall Plan combined with the public provision of infrastructure, the surge of intra-European trade, and the reconstruction process that followed the devastation of the war. This paper is an attempt to formalize and quantify the direct contribution of each one of these factors to growth during the European Golden Age. Our results highlight the importance of reconstruction growth and structural change, and point to the limited role of the Marshall Plan, and the late contribution of intra-European trade.Economic Growth, European Economic History 1913-, Computable General Equilibrium Models.
A first principles study of thiol-capped Au nanoparticles: Structural, electronic, and magnetic properties as a function of thiol coverage
We have studied the stability of thiolated Au38 nanoparticles (NPs) via density functional theory based calculations varying the coverage from 0 up to 32 molecules. Three different initial core arrangements were considered for the cluster, spherical, tubular, and bi-icosahedral, while thiol groups were attached to the cluster via the sulfur atom either as single molecules or forming more complex staple motifs. After molecular dynamics runs several metastable configurations are found at each coverage thus allowing to analyze the properties of the NPs in the form of ensemble averages. In particular, we address the structural and electronic properties as a function of the number of thiols. The study emphasizes the strong influence of the core structure on the stability of the NPs, and its interplay with the thiol coverage and adsorption geometries. The magnetic properties of the NPs have also been explored via spin-polarized calculations including spin-orbit coupling. No evidence for the existence of a robust intrinsic ferromagnetism is found in any of the structures. © 2013 AIP Publishing LLC.This research was supported by the Spanish Ministry of Innovation and Science under Project No. MAT2010-18432.Peer Reviewe
Coinfection in a stochastic model for bacteriophage systems
A system modeling bacteriophage treatments with coinfections in a noisy context is analysed. We prove that in a small noise regime, the system converges in the long term to a bacteria-free equilibrium. Moreover, we compare the treatment with coinfection with the treatment without coinfection, showing how coinfection affects the convergence to the bacteria-free equilibrium
