Abstract
Problems of the Theory of Efficient Markets and the Empirical Testing of it
This article ventilates various, theoretical and empirical problems of efficient markets. Following a brief introduction to Fama’s theoretical groundwork, an attempt is made to reformulate the concept of the information efficiency of markets, using the marginal costs of information procurement to distinguish among centrally published, decentrally published and temporarily monopolized information. The new approach enables an economically substantiated distinction to be drawn between high and low information efficiency and, in addition, to reject the famous information paradox as a spurious problem. The critical discussion of hypothesis tests in the second part of the article culminates in the conclusion that all tests of the hypothesis of high information efficiency are invariably only weak, that is, not very restrictive tests.
