Generalized minority games with adaptive trend-followers and contrarians.
نویسندگان
چکیده
We introduce a simple extension of the minority game in which the market rewards contrarian (respectively, trend-following) strategies when it is far from (respectively, close to) efficiency. The model displays a smooth crossover from a regime where contrarians dominate to one where trend-followers dominate. In the intermediate phase, the stationary state is characterized by non-Gaussian features as well as by the formation of sustained trends and bubbles.

Effects of contrarians in the minority game.
We study the effects of the presence of contrarians in an agent-based model of competing populations. Contrarians are common in societies. These contrarians are agents who deliberately prefer to hold an opinion that is contrary to the prevailing idea of the commons or normal agents. Contrarians are introduced within the context of the minority game (MG), which is a binary model for an evolving ...

متن کاملRational Trend-Followers and Contrarians in Excessively Volatile, Correlated Markets
This paper studies an overlapping generations model with multiple securities and heterogeneously informed agents. There are two types of multiplicity of equilibria, one due to noisy rational expectations and the other resulting from self-fulfilling prophecies. Under general conditions, there exists an equilibrium in which stock returns are highly volatile and strongly correlated, even if all un...
