摘要：Existing studies have shown that experiencecan affect price expectation and investment behavior, but most studies focus onthe effects of bubbles rather than crash. In this lab in the field experiment, weadapt the experimental design of Gong et al. (2013) and change the twobubble-and-crash markets setting to two crash-and-recovery markets.  We recruit real individual investors toinvestigate how they behave in a laboratory asset market crash and whether theyform different price expectations and behave differently after experiencing acrash and its recovery, especially in terms of disposition effects. The experimentalresults indicate that afterexperiencing a laboratory crash-and-recovery, investors tended to hold higherexpectations on future market prices, trade smaller sizes a reduction in theduration of holding both profitable and loss-incurring stocks. Overall, experiencedinvestors’ expectations for future stock prices become more optimistic, and thedisposition effect is mitigated. The increase in expectations also weakens theimpact on the disposition effect of investors.
