An Approach to the stability of international environmental agreements: the absorbing sets solution
(2003-12)
We study international environmental negotiations when agreements between countries can not be binding. A problem with this kind of negotiations is that countries have incentives for free-riding from such agreements. We ...
Profit and Cost in "Modern" Post-Marxian Profit Theory: A Case Study from Varian's "Intermediate Microeconomics"
(2003-09)
In this paper, I examine the treatment of competitive profit of professor Varian in his
textbook on Microeconomics, as a representative of the “modern” post-Marxian view on competitive profit. I show how, on the one hand, ...
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 ...
Factores de riesgo y supervivencia libre de tumor en pacientes con trasplante renal de cadáver
(2003)
[Background] There is an agreement in the fact that cancer incidence in transplant recipients increases at a rate disproportionately greater than in the general population. Several clinical studies have identified cancer ...
Productivity's development in the Basque Economy during the period 1985-1994
(1998-09)
[EN] The aim of this paper is to analyse the development of Basque Country's economy's productivity in the period 1985-1994 and, identify which are the factors that decide that evolution. We specify a Cobb-Douglas production ...
A Fundamental Contradiction in Standard Rent Theory: A Case Study on Varian's "Intermediate Microeconomics"
(2004)
In this paper, I examine Varian’s treatment of rent in his textbook on Microeconomics. I argue that he holds contradictory conceptions: sometimes rent is defined as surplus over cost whereas sometimes it is defined as cost, ...
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 ...
Entrada endógena ineficiente
(2002-07)
[EN] Stewart (1994) presents a model of endogenous entry. In his article Stewart proposes the following topic for future research: "An important feature of the model is that entry would be inefficient from the producers' ...
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.
