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…
A project scheduling problem is defined by a set of activities, their precedence relations, and the corresponding execution times. The goal is to sequence and schedule the activities so that some performance measure of interest is optimized. Often, specific resources that exist in a limited amount are required to execute the activities. This extension of…
We take the axiomatic approach to uncover the structure of the revenue-sharing problem from broadcasting sports leagues. Our starting point is to explore the implications of three basic axioms: additivity, order preservation and weak upper bound. We show that the combination of these axioms characterizes a large family of rules, which is made of compromises…
La medición de la eficiencia en los diversos ámbitos de la economía pública ha suscitado gran interés durante las últimas décadas. Las técnicas más utilizadas en la literatura para estimar el desempeño de las unidades productivas han sido claramente los modelos de frontera no paramétricos tales como el DEA, el FDH o, más recientemente, sus…
Un problema de atribución consiste simplemente en determinar cuál es la relevancia de una serie de factores para la consecución de un objetivo particular. Aunque la formulación del problema parece sencilla, no lo es tanto, y por ello existe toda una literatura sobre este problema en muy diversos campos. Por ejemplo, este tipo de problemas…
There is a growing literature on enhancing the interpretability of Machine Learning methods involved in Data Driven Decision Making. Interpretability is desirable for non-experts; it is required by regulators for models aiding, for instance, credit scoring; and since 2018 the European Union has extended this requirement by imposing the so-calledright-to-explanation in algorithmic decision making. Mathematical…
