An Alternative View of the US Price-Dividend Ratio Dynamics
(2014-12)
As a necessary condition for the validity of the present value model, the price-dividend ratio must be stationary. However, significant market episodes seem to provide
evidence of prices significantly drifting apart from ...
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 ...
El espacio cuerpo en la educación transformadora
(2014)
[ES] La integralidad de los seres humanos conlleva la comprensión del cuerpo como parte inseparable del ser que somos. Somos consciencia corpórea. Psicología, fisiología, emocionalidad e inclusive vivencia espiritual y ...
A new look at Marx's refutation of Ricardo's refutation of the labor theory of value
(2011)
In this paper, I would like to bring back to light the forgotten critique of Marx to the widely accepted view that Ricardo succeeded in refuting the universal validity of the labor theory of value in "Principles", chapter ...
Are Labor and Freedom Compatible? Political Economy, Hegel’s Practical Philosophy and the Young Marx
(Fundamentos del Análisis Económico I, UPV/EHU, 2017)
The question discussed in this paper is whether a political society not emancipated from labor can be a free society. In a less abstract way, the question can be posed as follows; can a society with a laboring class and a ...
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 two-stage stochastic mixed integer optimization models
(2018-10-22)
Stochastic optimization problems of practical applications lead, in general, to some large models. The size of those models is linked to the number of scenarios that defines the scenario tree. This number of scenarios can ...
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.
Characterization of efficient networks in a generalized connections model with endogenous link strength
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2019-05-09)
We consider a natural generalization of Jackson and Wolinsky s (1996) connections model where the quality or strength of a link depends on the amount invested in it and is determined by a non-decreasing function of that ...
