Abstract: 

We consider an experimental setting where traders in stock markets or exchange rate markets receive one stylized piece of information at a time about the value of an asset. We find that having limited knowledge about the prior distribution of true asset values does not hamper the decision making by traders and markets. There is empirical support for the common modeling assumption of simplifying agent heterogeneity into two types, a rational one and a less rational one. A correspondence exists between the average degree of belief conservatism found with individual buying and selling prices and that observed with market prices.
