The real exchange rate of the dollar for a panel of OECD countries: Balassa-Samuelson or distribution sector effect?

The purpose of this paper is to analyse the role of productivity in the behaviour of the dollar real exchange rate against a group of OECD countries’ currencies. To do this, a general specification is tested, paying special attention to the breakdown of the productivity variable into tradables, non-tradables and distribution sector productivity. The applied methodology relies on the Pool Mean Group estimation methodology proposed by Pesaran et al (1999) to obtain error correction models in panels without imposing equal long and shortrun parameters for the panel. The results point to the relevance of the differences in the distribution sector productivity to explain the real exchange rate, especially in the European Union countries. These results are in accordance with New Open Macroeconomics models predictions concerning the role of both distribution sector productivity and fiscal expenditure on the real exchange rate.real exchange rates, productivity, cointegration, panel, distribution sector

How translators can improve multilingual terminology in a link: teaching case study examples

Gómez-Camarero, C. y Palomares Perraut, R. (2016). How translators can improve multilingual terminology in a link: teaching case study examples (Poster). En 38th Translating and the Computer Conference (TC38). London, 17-18 november 2016.El objetivo de este trabajo consiste en describir un método para enriquecer y mejorar la terminología multilingüe del traductor intérprete de textos especializados en diversas disciplinas desde un único link. El método consiste en utilizar lenguajes controlados, especialmente tesauros con tecnología linked open data en el contexto de la web semántica. Esta tecnología permite que cada concepto sea identificado de forma unívoca con una URI (Uniform Resource Identifier), utilizando el lenguaje SKOS (Simple Knowledge Organization System), uno de los lenguajes de la web semántica to use of knowledge organization systems such as thesauri, classification schemes, subject heading systems and taxonomies. Con este trabajo queremos destacar la importancia para el traductor de los lenguajes controlados, que constituyen unas herramientas muy eficaces y útiles para conocer, no sólo los conceptos a traducir, sino para tener una visión más amplia del contexto de los textos especializados. Además, es fundamental que el estudiante de traducción sepa manejarse en los nuevos espacios La finalidad de utilizar estos lenguajes controlados en nuestras clases reside en destacar la importancia y valor de saber qué es una palabra clave. Para ello, se describen varios ejemplos empleados en clase para enseñar las funciones y la utilidad de un lenguaje controlado para el traductor/intérprete: para desambiguar, para controlar el contexto de un concepto, para aumentar el vocabulario, para conocer más términos del mismo campo semánticos, para conocer los equivalentes normalizados en otros idiomas. Entre los lenguajes controlados empleados en estas prácticas se encuentran el Tesauro de la Unesco, el Tesauro del Patrimonio Cultural de España, los encabezamientos de materia de las bibliotecas nacionales: Catálogo de Autoridades de la Biblioteca Nacional Española, el Répertoire d’autorité-matière encyclopédique et alphabétique unifié (Rameau) de la Bibliothèque Nationale Française, la Library of Congress Subject Headings-LCSH.Universidad de Málaga.

Classes of Symmetric Cayley Graphs over Finite Abelian Groups of Degrees 4 and 6

The present work is devoted to characterize the family of symmetric undirected Cayley graphs over finite Abelian groups for degrees 4 and 6.Comment: 12 pages. A previous version of some of the results in this paper where first announced at 2010 International Workshop on Optimal Interconnection Networks (IWONT 2010).

Symmetric Interconnection Networks from Cubic Crystal Lattices

Torus networks of moderate degree have been widely used in the supercomputer industry. Tori are superb when used for executing applications that require near-neighbor communications. Nevertheless, they are not so good when dealing with global communications. Hence, typical 3D implementations have evolved to 5D networks, among other reasons, to reduce network distances. Most of these big systems are mixed-radix tori which are not the best option for minimizing distances and efficiently using network resources. This paper is focused on improving the topological properties of these networks. By using integral matrices to deal with Cayley graphs over Abelian groups, we have been able to propose and analyze a family of high-dimensional grid-based interconnection networks. As they are built over $n$-dimensional grids that induce a regular tiling of the space, these topologies have been denoted \textsl{lattice graphs}. We will focus on cubic crystal lattices for modeling symmetric 3D networks. Other higher dimensional networks can be composed over these graphs, as illustrated in this research. Easy network partitioning can also take advantage of this network composition operation. Minimal routing algorithms are also provided for these new topologies. Finally, some practical issues such as implementability and preliminary performance evaluations have been addressed

Estimating exports and imports demand for Manufactured goods: The role of FDI

In this paper we examine the joint performance of FDI and trade under a full liberalization process consistent with New Trade Theory models. The testing framework consists of the estimation of demand for exports and imports of manufactured goods for a panel containing the majority of the EU countries as well as the US and Japan. The model includes as explanatory factors, not only the traditional determinants of trade, but also new ones, such as the stock of foreign direct investment (FDI). We apply a variety of panel unit root and cointegration tests to the cases of both homogeneous and heterogeneous panels. Whereas there is no evidence of cointegration when using just the traditional formulation, the results are favorable to the existence of long-run relationships linking the variables of the augmented model. Moreover, the results point mainly to a complementarity relationship between trade and FDI.

A panel cointegration approach to the estimation of the peseta real exchange rate

In this paper we estimate different specifications of a model for the determination of the bilateral real exchange rate of the peseta relative to nine European Union members. The model is based on Meese and Rogo (1988) monetary approach as extended by MacDonald (1998). The applied econometric techniques are the recent panel cointegration tests developed by Kao (1999), McCoskey and Kao (1998) and Pedroni (1999) for homogeneous and heterogeneous panels. The results are favorable to a model containing relative productivities in tradables and non-tradables and the real interest rate di¤erentials as explanatory variables.real exchange rate, European Monetary Union, panel cointegration

Nonlinear trend stationarity of real exchange rates: the case of the Mediterranean countries

The aim of this article is to provide additional evidence on the fulfilment of the Purchasing Power Parity hypothesis in the so-called Mediterranean countries. In order to test for the empirical validity of such hypothesis, we have applied two types of unit root tests. The first group is due to Bierens (1997) who generalizes the alternative hypothesis to nonlinear trend stationariry and, the second is the Leybourne, Newbold and Vougas (1998) approach that uses a nonlinear specification for the intercept and slope in order to detrend the series. The results suggest that the evidence in favour of the Purchasing Power Parity hypothesis increases when we allow for nonlinear alternatives

Re-examining CO2 emissions. Is the assessment of convergence meaningless?

This paper re-examines CO2 emissions in 22 OECD countries over the period 1870–2006. It contributes to the field of environmental economics trying to clarify the possible sources of the mixed evidence on CO2 emissions convergence. To this end we employ a detailed methodological strategy. First we start with standard linear tests as the ones proposed by Ng and Perron (2001). Then, using the Lee and Strazicich (2003) tests, we take into account the possible existence of structural breaks in the series. Finally, we apply a non-linear test within a smooth transition autoregressive (STAR) framework proposed by Kapetanios et al. (2003). The empirical evidence provided by our methodological strategy suggests that the original per capita CO2 emissions for the largest span, from 1870 to 2006, are stationary, so that to continue with the assessment of convergence in this context would not be adequate. However if we consider instead the period 1950-2006, per capita CO2 emissions are in a non-stationary local regime. Thus, in this case we proceed with the study of convergence. Bearing in mind plausible nonlinearities, CO2 emissions convergence is assessed using two versions of the Kapetanios et al. (2003) test, and conclude that there is no robust convergence among these 22 OECD countries.CO2 emissions, stationarity, non linear test, smooth transition, convergence.
