A lot of research has been dedicated to solving combinatorial optimization problems during past decades, both in the Operations Research field and in Artificial Intelligence. As a result, researchers and/or practitioners are able to choose between a wide range of both exact and approximate techniques when faced with an optimization problem of that type. Nevertheless,…

The tariff rate quota (TRQ) is a common market access instrument in global agricultural trade that allows a predetermined quantity of a product to be imported at a lower tariff rate than the rate typically applied to that product. In this study, we examine the design and administration of TRQ systems from an operations management…

Abstract This paper theoretically explores the role of elites in the rise of progressive taxation in Western countries at the beginning of the XXth century and in its posterior erosion in the last four decades. We focus on its interaction with the level of inequality between the elite and the citizens. We analyse a stylized…

El cómputo exacto de soluciones de juegos cooperativos presenta una alta complejidad computacional cuando el número de jugadores involucrados es lo suficientemente grande. En este sentido, las metodologías de muestreo se presentan como alternativa para su aproximación en general. En esta charla revisaremos algunas de las propuestas en la literatura basadas en muestreo, así como…

La investigación científica y la divulgación, esto es poner al alcance de un público más amplio son dos caras de una misma moneda, pero no es lo mismo. Entre los científicos y también entre los economistas encontramos a grandes investigadores que con el paso de los años también se han convertido en divulgadores muy populares…

This paper formulates and analyzes a dynamic game between two trading regions that face a transboundary pollution problem. We study how the distribution of firms and trade costs affect the optimal emission decision of governments and how the resulting environmental policy would alter the allocation of the industry between both countries. The underlying microeconomic behaviour…

Project management is an important body of knowledge and practices that comprises the planning, organization and control of resources to achieve one or more pre-determined objectives. In this presentation, we introduce ProjectManagement, a new R package that provides the necessary tools to manage projects in a broad sense, and illustrate its use by examples. We…

We consider the problem of randomly allocating indivisible units of a resource among agents with conflicting claims on the resource. In the two-agent case, we characterize three focal rules combining axioms reflecting principles of compensation and sacrifice: probabilistic uniform awards, probabilistic uniform losses and probabilistic concede-and-divide. In the general case of n agents, the two…

Interior point methods (IPMs) have shown to behave very well in some classes of large-scale structured optimization problems. We will discuss a successful approach for block-angular structures that relies on the combination of Cholesky factorizations and preconditioned conjugate gradients for the normal equations. In the first part of the talk we will outline such specialized…
