Self-involved Belief and Disposition Effect:An Agent-based Simulation
After a review of the extant theories on the disposition effect (DE),we examine whether DE is caused by the selfinvolved belief persistence.Based on the specification of various types of belief persistence,we employ agent-based computational simulation to generate artificial price and trading data.We test DE indirectly by the approach referred by Lakonishok and Smidt (1986) and directly as Odean (1998) does,and find selfinvolved belief persistence would generate true DE.However,if the agents are allowed to adjust their self-involved belief according to their prior sale-related belief,DE will shrink or vanish.Simple belief persistence creates mean reversion in price but no true DE in trading behavior.The main conclusion is robust to the change of other exogenous parameters.
