Expectationally-driven market volatility: an experimental study
We study the existence and robustness of expectationally-driven price volatility in experimental overlapping generation economies. In the theoretical model under study there exist pure sunspot equilibria which can be learned if agents use some adaptive learning rules. Our data show the existence of expectationally-driven cycles, but only after subjects have been exposed to a sequence of real shocks and learned a real cycle. In this sense, we show evidence of path-dependent price volatility.
