We report the results of an experiment designed to study the role of trading institutions in the formation of bubbles and crashes in laboratory asset markets. We employ three trading institutions: Call Market, Double Auction, and T\^atonnement. The results show that bubbles are significantly smaller in uniform-price institutions than in Double Auction. We reproduce this and other critical patterns of the data by calibrating a heterogeneous agent model with fundamental and myopic-noise traders. The model produces larger bubbles under Double Auction because multiple trades occur within a period, amplifying the impact of myopic traders with positive bias on transaction prices. |
