AN INPUT-OUTPUT APPROACH TO THE MEASUREMENT OF PRODUCTIVITY DIFFERENCES

This paper deals with the measurement of efficiency differences among countries within a federation. The key tool is the use of a suitable interpretation of the non-substitution theorem in order to get a natural technological standard. Two alternative indices are proposed. One provides a structural productivity measure, independent of consumption and prices. The other consists of a price index associated with the equilibrium aggregate demand.Input-Output Analysis; Nonsubstitution Theorem; Measurement of Productivity

MULTIDIMENSIONAL INEQUALITY AND SOCIAL WELFARE

This paper provides a cardinal welfare measure for the allocation of a bundle of goods among a group of people. Social welfare is measured as the sum of n partial indices, one for each good, each of which consists of a function of the amount of the good availabe and its dispersion, measured by Theil's first inequality index. Some applications of this welfare measure are also suggested.Inequality and Welfare; Social Goods; Cardinal Welfare Measures.

Time-dependent density functional study of the electronic spectra of oligoacenes in the charge states -1, 0, +1, and +2

We present a systematic theoretical study of the five smallest oligoacenes (naphthalene, anthracene, tetracene, pentacene, and hexacene) in their anionic,neutral, cationic, and dicationic charge states. We used density functional theory (DFT) to obtain the ground-state optimised geometries, and time-dependent DFT (TD-DFT) to evaluate the electronic absorption spectra. Total-energy differences enabled us to evaluate the electron affinities and first and second ionisation energies, the quasiparticle correction to the HOMO-LUMO energy gap and an estimate of the excitonic effects in the neutral molecules. Electronic absorption spectra have been computed by combining two different implementations of TD-DFT: the frequency-space method to study general trends as a function of charge-state and molecular size for the lowest-lying in-plane long-polarised and short-polarised $\pi\to\pi^\star$ electronic transitions, and the real-time propagation scheme to obtain the whole photo-absorption cross-section up to the far-UV. Doubly-ionised PAHs are found to display strong electronic transitions of $\pi\to\pi^\star$ character in the near-IR, visible, and near-UV spectral ranges, like their singly-charged counterparts. While, as expected, the broad plasmon-like structure with its maximum at about 17-18 eV is relatively insensitive to the charge-state of the molecule, a systematic decrease with increasing positive charge of the absorption cross-section between about 6 and about 12 eV is observed for each member of the class.Comment: 38 pages, 11 figures, 7 tables, accepted for publication in Chemical Physic

EFFICIENCY AND CORE PROPERTIES OF VALUATION EQUILIBRIUM WITH INCREASING RETURNS

This paper considers market economies involving the choice of a public environment when there are nonconvexities in production. It discusses the decentralization of efficient allocations by means of valuation equilibrium, adapting to many private goods the notion due to Mas-Colell (1980) which extends the Lindahlian approach to the pure theory of public goods. It is shown that a valuation equilibrium satisfies the two welfare theorems and is in the core.Valuation Equilibrium, Increasing Returns to Scale, Efficiency.

Objeción de conciencia de los notarios españoles con motivo de la nueva ley de jurisdicción voluntaria

La Ley de Jurisdicción Voluntaria española de 2015 habilita a los notarios para que instruyan el acta previa de capacidad y celebren matrimonios civiles, también de personas del mismo sexo. Dada la obligación del notario de actuar a petición de los particulares, este profesional podría verse forzado en contra de su conciencia respecto de esos matrimonios. La presente investigación tiene por objeto valorar la viabilidad del ejercicio del derecho de objeción de conciencia de los notarios españoles, así como la licitud moral de su cooperación al mal. Los elementos normativos examinados juegan en contra del reconocimiento de la objeción de conciencia del notario, que bien podría haberse admitido sin detrimento sustancial del objetivo perseguido por la reforma del matrimonio en el ordenamiento jurídico español. La investigación constata la desprotección jurídica que sufre la libertad de conciencia del notario

Nanoporous PMMA: A novel system with different acoustic properties

The acoustic properties of closed cell nanoporous and microporous poly(methyl methacrylate) (PMMA) foams have been well characterized, showing that nanoporous PMMA exhibit a different absorption coefficient and transmission loss behavior in comparison with microporous PMMA. Experimental differences may be explained by the different wave propagation mechanism in the micro and nanoscale, which is determined by the confinement of both the gas (Knudsen regime) and the solid phases. These results place nanoporous materials as a new class of polymeric porous material with potential properties in the field of acoustics, especially in multifunctional systems requiring a certain degree of soundproofing

THE THREE MUSKETEERS: FOUR CLASSICAL SOLUTIONS TO BANKRUPTCY PROBLEMS

This paper provides a comparative analysis of some classical solutions to bankruptcy problems from an axiomatic viewpoint. These rules are the constrained equal-awards rule, the constrained equal-losses rule, the proportional rule and the Talmud rule. The purpose of this study is to facilitate the understanding of their differences and to clarify the type of situations in which each of these rules is better.Bankruptcy problems, proportional solution, equal-awards solution

- VALUATION EQULIBRIUM REVISITED

This paper extends the notion of valuation equilibrium which applies to market economies involving the choice of a public environment. Unlike some other recent work, it is assumed here that consumers and firms evaluate alternative environments taking market prices as given (hence this notion is closer to that of competitive equilibria). It is shown that valuation equilibria with balanced tax schemas yield eficient allocations and that eficient allocations can be decentralized as valuation equilibria, with tax schemas that may be unbalanced.valuation equilibrium, non-convexities, public goods

Do Ourense medieval: o notario Gonzalo Pérez do Mato e o mosteiro de Santa Comba de Naves

O presente contributo presenta un conxunto documental protagonizado polo notario ourensán do século XIV Gonzalo Pérez do Mato e a súa descendencia, e que ilustran a vinculación destes co mosteiro de Santa Comba de Naves en canto foreiros do cenobio. Destacan, neste sentido, os pergamiños que nos informan sobre as vicisitudes do couto de Mende. No final editamos o testamento deste notario e da súa filla Maior Pérezinfo:eu-repo/semantics/publishedVersio

Capacidad de ejercicio de las personas naturales en la actuacion ante notario

60 p.Esta investigación pretende identificar los problemas que debe enfrentar el Notario en los casos en que le corresponda certificar la capacidad de ejercicio de las personas físicas. Además, de lo antes señalado, se buscará determinar si la ley le ha encomendado expresamente al Notario el cumplimiento de la función ya descrita, o si bien, esto obedecería más bien a una suerte de deber funcionario. También podremos apreciar, en el desarrollo del presente trabajo, la utilidad o beneficios que puede reportar la interrelación del derecho con otras disciplinas Con el fin de alcanzar los objetivos propuestos, se realizó un estudio y análisis de la bibliografía pertinente. Pero además, dada las características de la hipótesis planteada, se consultó la opinión de las personas que deben enfrentar esta problemática, es decir, los Notarios
