In this document we propose a model based in matching games to analyze the problem of workers' selection by the National Electoral Institute of Mexico. After a revision of the theoretically relevant results, an allocation mechanism is proposed to select the workers. This mechanism improves the...

The Kyoto Protocol sets national quotas on CO2 emissions and allows international trade of these quotas. We argue that this trade is characterized by asymmetric, identity-dependent externalities, and show that bilateral trade may not be sufficient for an efficient allocation of emissions. We...

The Kyoto Protocol sets national quotas on CO2 allowing international emissions trading. We argue that this trade is characterized by asymmetric, identitydependent externalities, and show that bilateral trade may not be sufficient for, and may even prevent, an efficient allocation of emissions....

We characterize the stationary competitive equilibrium in a model in which private decisions have to be made to define effective property rights on land. We show that there is an interior competitive equilibrium in which there will be some agents producing in free access lands and others in...
