Rational expectations in an experimental asset market with shocks to market trends

We construct an experimental asset market in which the time trend of the fundamental value is subject to a shock. The design of the experiment allows testing of whether prices adhere to Rational Expectations levels, and whether there is over- or under-reaction to new information. We find that prices conform closely to Rational Expectations and episodes of mispricing are rare. A meta-analysis allows us to update our beliefs about whether experimental asset markets exhibit a generic tendency to misprice, particularly in bearish environments.
