Abstract

ABSTRACTA series of experiments illustrate that relaxing short‐selling constraints lowers prices in experimental asset markets, but does not induce prices to track fundamentals. We argue that prices in experimental asset markets are influenced by restrictions on short‐selling capacity and limits on the cash available for purchases. Restrictions on short sales in the form of cash reserve requirements and quantity limits on short positions behave in a similar manner. A simulation model, based on DeLong et al. (1990), generates average price patterns that are similar to the observed data.
