En el análisis de la exclusión social, se ha constatado la importancia de la dimensión trabajo. La persistencia del paro, la temporalidad en el empleo o los bajos salarios, inciden de forma importante sobre los niveles de pobreza y exclusión social. En este trabajo se ha recopilado información sobre distintas variables relacionadas con el mercado…
The aim of this work is to propose a statistical methodology in order to estimate the macromagnitud Gross Value Added per capita (GVApc) in the local geographical area. The procedure proposed consists of estimating a panel model which includes Griffith’s spatial filtering (1996, 2000) to capture the spatial dependence in the whole analyzed period. The…
Optimization problems involving polynomial functions are of great importance in applied mathematics and engineering, and they are intrinsically hard problems. They arise in important engineering applications such as the sensor network localization problem, and provide a rich and fruitful interaction between algebraic-geometric concepts and modern convex programming. In this talk, we will discuss some recent…
Abstract Los juegos TU como funciones de particiones son estructuras apropiadas para modelizar las ganancias/costes de una coalición teniendo en cuenta como se organizan el resto de los jugadores. En esta charla revisaremos algunos valores propuestos en la literatura, centrándonos en sus propiedades. En particular, revisaremos el valor de Myerson (Myerson 1977), el valor de…
Abstract This paper extends the measurement of dynamic productivity change over time to provide its full decomposition into economically meaningful components in the Data Envelopment Analysis framework. The dynamic approach accounts for dynamics of production decisions via adjustment costs and is visualized as a dynamic Luenberger productivity change indicator. The paper also estimates the dynamic…
Abstract This paper studies the evolution of the monetary policy transmission mechanisms in the US after the financial crisis and the extraordinary monetary stimulus applied since 2008. The implementation of a modified Dynamic Factor Model allows the identification of two different structural scenarios based on the information contained in a large dataset of 110 variables….
Brazil is proportionally a relatively unimportant player in the world fisheries scenario. However, small-scale fisheries (SSF) specifically are crucial for local livelihoods and the food security of millions of people, both on the coast and inland. Such fisheries provide more than 50% of the total Brazilian catches, suggesting that they can be highly impacting on…
Abstract In a two-sector economy, we consider the endogenous determination of the level of competition in the imperfectly competitive sector, under democratic, non-manipulated voting. In the context of the Salop’s (1979) circular model, we identify conditions such that besides a competitive equilibrium (with most voters choosing the efficient level of transport cost), a «populist» equilibrium…
Abstract What are the implications of legal rules for growth and business expansion? This question has been at the center of the rich literature that explores the link between legal institutions and economic performance. While the scholarship has provided insights on the differential experience of countries which developed their own legal systems and those that…
Abstract During the last years, interest on hybrid metaheuristics has risen considerably in the field of optimization and machine learning. The best results found for many optimization problems in science and industry are obtained by hybrid optimization algorithms. Combinations of optimization tools such as metaheuristics, mathematical programming, constraint programming and machine learning, have provided very…
