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 ...

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 ...

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 ...

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 ...

This paper studies the e ect of home-owners' migration costs on migration and unemployment in an economy where workers move both for work- and nonwork- related reasons. To this end, a search model with heterogeneous locations ...

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 literature on foreign direct investment has analyzed firms’ location decisions when they invest in R&D to reduce production costs. Such firms may set up new plants in other developed countries while maintaining their ...

This paper studies how the size of the labour market aff ects workers' decision to invest in human capital. We consider a model of mismatch where firms rank workers according to their level of skills. The matching process ...

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 ...

In this paper, we analyze the effect that the timing of wage setting (i. e. whether wages set sequentially or simultaneously) has on the investment in R&D of firms, when that investment increases the productivity of labor, ...
