“…Most of these experimental asset markets let participants trade financial assets with others making use of a continuous double auction or a call market mechanism. 1 The finding that bubbles disappear when identical markets are repeated is very robust in these settings, in which participants trade for a finite number of periods, with usually about 10-20 periods per market (e.g., Smith et al, 1988;King et al, 1993;Van Boening et al, 1993;Dufwenberg et al, 2005;Haruvy et al, 2007;Hussam et al, 2008; the findings can even persist in considerably more difficult variations, e.g., Füllbrunn et al, 2014a;Weber et al, 2018).…”
