A Unifying model of strategic network formation
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2015-02-17)
We provide a model that merges two basic models of strategic network formation and incorporates them as extreme cases: Jackson and Wolinsky' s connections model based on bilateral formation of links, and Bala and Goyal' s ...
Efficiency vs. Stability in a Mixed Network Formation Model
(Departamento de Fundamentos del Análisis Económico I, 2015-03-26)
The purpose of this paper is twofold. First, the incomplete results relative to effciency in a transitional model introduced in a previous paper, distinguishing two types of links, strong or doubly-supported and weak or ...
A Marginalist Model of Network Formation
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2016-08-18)
We develop a network-formation model where the quality of a link depends on the amount invested in it and is determined by a link-formation "technology" , an increasing strictly concave function which is the only exogenous ...
The impact of liberalizing cost-saharing on basic models of network formation
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2015-09-12)
This paper studies the impact of "liberalizing " the cost-sharing of links on some basic models of network formation. This is done in a setting where both doubly supported and singly supported links are possible, and which ...
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 ...
Efficiency of weighted networks
(Fundamentos del Análisis Económico I, UPV/EHU, 2017-11-14)
In this paper, we address the question of the efficiency of weighted networks in a setting where nodes derive utility from their direct and indirect connections. Under rather general conditions, based on a set of assumptions ...
A Note on Efficiency in a Unifying Model of Strategic Network Formation
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2018-05-15)
The main point of this note is to provide a simpler and shorter proof of the result on efficiency in Olaizola and Valenciano (2017a) based on a result on efficiency of weighted networks in Olaizola and Valenciano (2017b). ...
