Empirical evidence shows that vertically integrated producers are more productive, bigger and are matched to better suppliers (with high productivity and size). I present a dynamic stochastic model of an industry with heterogeneous firms interacting as buyers and sellers, and market frictions...

We study how the sequential formation of free trade areas affects trade flows between member countries. In a three-country, three-good model of comparative advantage if two countries have an FTA, and both sign a similar agreement with the third, trade between the two decreases. However, if only...

We first observe that two of Maskin's results do not extend beyond three players: we construct a four-player partition function with non-positive externalities whose unique solution is inefficient, as well as a four-player characteristic function that has a unique efficient solution for each...

This paper puts forth a unified theory of growth that captures a number of relevant features of countries’ transitions from stagnant, predominantly rural economies to vibrant, industrialized economies that have been overlooked by the literature. In our theory, increasing variety of consumer...

This paper looks at the relationship between fiscal and political decentralization and the evolution of regional inequalities in a panel of 26 countries -- 19 developed and 7 developing -- for the period between 1990 and 2006. Using an instrumental variables method, it finds that whereas for the...

This article is a survey on bargaining theory. The focus is the game theoretic approach to bargaining, both on its axiomatic and strategic counterparts. The application of bargaining theory to large markets and its connections with competitive allocations are also discussed.

Este breve artículo glosa algunas de las aplicaciones recientes de sistemas dinámicos estocásticos a la Teoría de Juegos y la Economía. El modelo que se describe con más detalle demuestra que la única asignación estocásticamente estable de un proceso de intercambio entre coaliciones...

We study the classic implementation problem under the behavioral assumption that agents myopically adjust their actions in the direction of better-responses within a given institution. We offer results both under complete and incomplete information. First, we show that a necessary condition for...

We study the relationship between urban sprawl and obesity. Using data that tracks individuals over time, we find no evidence that urban sprawl causes obesity. We show that previous findings of a positive relationship most likely reflect a failure to properly control for the fact the individuals...

Our concern is the extension of the theory of the Shapley value to games with externalities. Using the standard axiom systems behind the Shapley value for an arbitrary exogenous coalition structure leads to the identification of bounds on players’ payoffs around an \"externality-free\" value....
