On solving two stage stochastic linear problems by using a new approach, Cluster Benders Decomposition
(2010-11)
The optimization of stochastic linear problems, via scenario analysis, based on Benders decomposition requires to appending feasibility and/or optimality cuts to the master problem until the iterative procedure reaches the ...
The Weekend-Dividend Effect in the Spanish Market
(University of the Basque Country, Department of Foundations of Economic Analysis II, 2002-06)
In this paper we develop an econometric test of a corollary of the irrelevance of the dividend policy principle, namely, that the rescheduling of dividends does not affect the market valuation of the firm. In particular, ...
On Downloading and Using CPLEX within COIN-OR for Solving Linear/Integer Optimization Problems
(2011-11)
The aim of this technical report is to present some detailed explanations in order to use the solver CPLEX within COIN-OR
environment. In particular, we describe how to download, install and use the corresponding source ...
Risk management for mathematical optimization under uncertainty
(2016)
We present a general multistage stochastic mixed 0-1 problem where the uncertainty appears everywhere in the objective function, constraints matrix and right-hand-side. The uncertainty is represented by a scenario tree ...
Two-Stage Nonparametric Regression for Longitudinal Data
(1999-01)
In the analysis of longitudinal data it is of main interest to investigate the existence of group and individual effects under correlated observations across time. In this paper, we develop a nonparametric two-step procedure ...
Absorbing Sets in Coalitional Systems
(2001-12)
The purpose of this paper is twofold: First, to present an approach and a solution for analyzing the stability of coalition structures: We define a coalitional system (a set and a binary relation on that set) that explains ...
Nonparametric estimation of time varying parameters under shape restrictions
(2001-01)
In this paper we propose a new method to estimate nonparametrically a time varying parameter model when some qualitative information from outside data (e.g. seasonality) is available. In this framework we make two main ...
Conditional beta pricing models: A nonparametric approach
(2010)
We propose a two-stage procedure to estimate conditional beta pricing models that allow for flexibility in the dynamics of assets' covariances with risk factors and market prices of risk (MPR). First, conditional covariances ...
Generating cluster submodels from a multistage stochastic mixed integer optimization model using break stage
(2013-07)
We present a scheme to generate clusters submodels with stage ordering from a (symmetric or a
nonsymmetric one) multistage stochastic mixed integer optimization model using break stage. We
consider a stochastic model ...
Measuring the Effect of the Real Estate Bubble: a House Price Index for Bilbao
(2011-11)
A spatio-temporal model is proposed aimed at producing an index of housing prices. A hedonic model with geographically varying coefficients is coupled with a non parametric estimation of the trend, whence a price index is derived.
