This paper studies the effects of the carbon-based ecosystem on a country's output. We propose and estimate a dynamic game production model in which a country's ecosystem, as measured by its reservoir of carbon in land biomass and soils, is a productive input. This reservoir is diminished when...

In 1979, the "Ley de Aviaciýn Comercial" (Commercial Aviation Act) was passed in Chile. Its main goal was to improve the air transport by means of "Open Sky Policies", competence (freedom of prices) and a progressive lesser intervention of the official authority. Since then an international air...

We model how individual preferences are shaped by strategic reciprocity choices. Our model accounts for heterogeneous players — with intrinsic altruistic, selfish or spiteful preferences — who randomly engage in short-run, as well as long-run, pair- wise interactions. To disentangle the...

This paper studies the welfare implications of equilibrium behavior in a market characterized by competition between two interconnected telecommunication firms, subject to constraints: the customers belong to a social network. It also shows that social networks matter because equilibrium prices...

Global games emerged as an approach to equilibrium selection. For a general setting with supermodular payoffs unique selection of equilibrium has been obtained through iterative elimination of strictly dominated strategies. For the case of global games with strategic substitutes, uniqueness of...

We model dynamic mechanisms for a global commons. Countries benefit from both consumption and aggregate conservation of an open access resource. A country's relative value of consumption-to-conservation is privately observed and evolves stochastically. An optimal quota maximizes world welfare...

We propose a model of strong reciprocity and trust that combines elements of personality psychology and behavioral economics. In the model, positive reciprocity and negative reciprocity are components of individual utility functions, while trust is an individual bias that distorts the beliefs...
