A Marginalist Model of Network Formation
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
A Note on Efficiency in a Unifying Model of Strategic Network Formation
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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). ... -
A Unifying model of strategic network formation
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
Absorbing Sets in Coalitional Systems
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 ... -
An Approach to the stability of international environmental agreements: the absorbing sets solution
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 ... -
Asymmetric flow networks
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(Departamento de Fundamentos del Análisis Económico I, UPV-EHU, 2012-06-22)
This paper provides a new model of network formation that bridges the gap between the two benchmark models by Bala and Goyal, the one-way flow model, and the two-way flow model, and includes both as particular extreme ... -
Characterization of efficient networks in a generalized connections model with endogenous link strength
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
Choice of Flexible Production Technologies Under Strategic Delegation
This work analyzes a managerial delegation model in which firms can choose between a flexible production technology which allows them to produce two different products and a dedicated production technology which limits ... -
Cost-Saving production technologies and strategic delegation
This work analyzes a managerial delegation model in which firms that produce a differentiated good can choose between two production technologies: a low marginal cost technology and a high marginal cost technology. For ... -
Efficiency of weighted networks
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
Efficiency vs. Stability in a Mixed Network Formation Model
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
From bilateral two-way to unilateral one-way flow link-formation
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(Departamento de Fundamentos del Análisis Económico I, 2014-11-26)
We provide a model that bridges de gap between the simplest variation of two benchmark models of strategic network formation: Bala and Goyal s one-way ow model without decay, where links can be unilaterally formed, and a ... -
Information, stability and dynamics in networks under institutional constraints
In this paper we study the effects of institutional constraints on stability, efficiency and network formation. More precisely, an exogenous "societal cover" consisting of a collection of possibly overlapping subsets that ... -
Internal Organization of Firms and Cartel Formation
We introduce and characterize a new solution concept for TU games. The new soluction is called SD-prenucleolus and is a lexicographic value although is not a weighted prenucleolus. The SD-prenucleolus satisfies several ... -
Network formation under institutional constraints
We study the effects of institutional constraints on stability, efficiency and network formation. An exogenous "societal cover" consisting of a collection of possibly overlapping subsets covering the set of players specifies ... -
The impact of liberalizing cost-saharing on basic models of network formation
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(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 ... -
Unilateral vs. Bilateral link-formation: Bridging the gap
Olaizola Ortega, María Norma; Valenciano Llovera, Federico
(Departamento de Fundamentos del Análisis Económico I, UPV/EHU, 2014-05-28)
We provide a model that bridges the gap between two benchmark models of strategic network formation: Jackson and Wolinsky' s model based on bilateral formation of links, and Bala and Goyal's two-way fl ow model, where links ...
