El objetivo de este artículo, que hace parte de un estudio más extenso, es analizar el tema de las fluctuaciones del producto en un escenario de competencia imperfecta a la luz de los hechos estilizados. Se conclue que estas se pueden originar por shocks de oferta o demanda, o simplemente por...

This article presents an equilibrium concept that, contrary to the traditional walrasian one, allows for the unbalance between supply and demand in different markets, making easier the analysis of those situations in which they differ persistently, as in the case of the labor market....

This paper shows one type of asymetric information problems, their theorethical implications, the design of contracts that mitigate them, as well as some experimental evidence. Furthermore, by extrapolating the results, the paper tries to illustrate certain macroeconomic implications obtained...

This paper characterizes interim efficient mechanisms for public good production and cost allocation in a two-type environment with risk neutral, quasi-linear preferences and fixed size projects, where the distribution of the private good, as well as the public goods decision, affects social...

Projects of the same type are subject to common type-specific shocks. Hence focusing is more risky within each period, but...

We show that, in repeated common interest games without discounting, strong `perturbation implies efficiency' results require that the perturbations must include strategies which are `draconian' in the sense that they are prepared to punish to the maximum extent possible. Moreover, there is a...
