Seminario 17/17: Guoyin Li (U. New South Wales) – Some Recent Advances in Polynomial Optimization

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…

Seminario 17/16: Gloria Fiestras Janeiro (U. Vigo) – Valores para juegos TU como funciones de particiones: una revisión

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…

Seminario 17/15: Magdalena Kapelko (Wroclaw University of Economics) – Measuring Productivity Change Accounting for Adjustment Costs: Evidence from the Food Industry in the European Union

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…
