Abstract:     
Accounting and finance researchers show semi-strong efficiency or lack thereof by using sequences of prices from CRSP and COMPUSTAT data for which there is not a model of how these prices came about through individual decisions. One needs a setting in which the prices (including bids and asks) as well information about individuals making the choices are both available. To begin to bridge the gap between theory and data we extend work done by experimental economists on the double auction and model price formation that is/is not semi-strong efficient. Agents in the model uncover prices in a manner reminiscent of Hayek (1948)'s notion of price discovery.
