Abstract

Recent Developments in the Theory of Efficient Capital Markets

The hypothesis that prices reflect all available information in financial markets is predominant in the financial literature. Despite the popularity of the efficient capital market hypothesis it has not been based on a rigourous theoretical foundation. Recently a highly technical literature has developed in which problems of information in competitive markets are rigourously analysed, and where the issue of informational efficiency of financial markets is explicitly addressed. The purpose of this paper is to give a non-technical introduction and review of this theoretical literature as it specifically relates to the efficient capital market hypothesis. Since the literature relies heavily on the rational expectations equilibrium concept market hypothesis we shall start out by discussing this methodology in some detail. Subsequent to this an illustrative model is developed which allows us to address the following issues of information in financial markets: information dissemination by prices, information costs, information and wealth dynamics, information dissemination by quantity signals, existence of markets and sequential trading.
