This paper presents a model for asset markets with a subjectively rational solution for the price of the traded asset. Traders cannot act objectively rational and an increase in the number of traders does not enlarge the information set neccessary for determining the "true'' price. Consequentely, many well-known "puzzles'' vanish as there is no objective truth to which data could live up. An empirical test is conducted which demonstrates the relevance of the argument across time, space, and markets.
