This paper adds a land market to a standard Harris-Todaro framework. In the standard model, the equilibrating force that limits rural-urban migration is a decline in the probability of formal employment, which follows from enlargement of the informal sector. The key insight of the present paper,...

Recent theoretical work has examined the spatial distribution of unemployment using the efficiency wage model as the mechanism by which unemployment arises in the urban economy. This paper extends the standard efficiency wage model in order to allow for behavioral substitution between leisure...

We study the impact of job proximity on individual employment and earnings. The analysis exploits a Swedish refugee dispersal policy to get exogenous variation in individual locations. Using very detailed data on the exact location of all residences and workplaces in Sweden, we find that having...

We develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to his/her Katz-Bonacich centrality measure. This measure takes into account both direct and indirect friends of each individual, but puts less weight to his/her...

[fre] Segmentation et marchés locaux du travail par Jacques-François Thisse et Yves Zenou . L'existence de segmentations et de cloisonnements spatiaux sur le marché du travail est un fait empirique bien établi. L'objet de cet article est d'exposer et d'évaluer les principales explications...

[fre] Salaire d'efficience et politique de l'emploi. . Une étude de quelques propositions, . par Yves Zenou.. . En s'appuyant sur un modèle de salaire d'efficience avec concurrence monopolistique sur le marché des produits, des propositions de politiques d'emploi sont étudiées : un système...

We develop a model in which delinquents compete with each other in criminal activities but may benefit from being friends with other criminals by learning and acquiring proper know-how on the crime business. By taking the social network connecting agents as given, we study the subgame perfect...

Finite population non-cooperative games with linear-quadratic utilities, where each player decides how much action she exerts, can be interpreted as a network game with local payoff complementarities, together with a globally uniform payoff substitutability component and an ownconcavity effect....

We study a structural model of R&D alliance networks in which firms jointly form R&D collaborations to lower their production costs while competing on the product market. We derive the Nash equilibrium of this game, provide a welfare analysis and determine the optimal R&D subsidy program that...
