Social interactions arguably provide a rationale for several important phenomena, from smoking and other risky behavior in teens to e.g., peer effects in school performance. We study social interactions in dynamic economies. For these economies, we provide existence (Markov Perfect Equilibrium...

Cycles dragged by switches in preferences are obtained in a stochastic model economy. Both the supply and the demand side, each one of them composed by infinite countable interacting agents, are modelled as dynamic probabilistic processes. Interactions happen at three levels. At a local one,...
