Abstract We consider two families of strategy-proof social choice functions based on the majority principle: extended majority voting rules on the universal domain of preferences over two alternatives and generalized median voter schemes on the domain of single-peaked preferences over a finite and linearly ordered set of alternatives. We characterize their respective subclasses of obviously…

Abstract In this paper a dynamic model of economic growth, tourism and environment is studied. The model considers tourists in the economy as optimizing agents, interacting with domestic consumers. The number of tourists arriving in the country follows the Tourism Are Life-cycle model with a tourism carrying capacity dependent on environmental quality. Tourism hurts environment and abatement activities have…

Abstract The appeal of the concept of perfectly competitive equilibrium (PCE), to describe the outcome of trade in competitive markets, relies on three assumptions: 1) in the absence of frictions, PCE is the result of the centralized or decentralized interaction of rational agents, 2) whenever the market is out of equilibrium, an adjustment process would…

Abstract We consider an online retailer facing heterogeneous customers with initially unknown product preferences. Customers are characterized by a diverse set of demographic and transactional attributes. The retailer can personalize the customers’ assortment offerings based on available profile information to maximize cumulative revenue. To that end, the retailer must estimate customer preferences by observing transaction…

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….
