Enhanced reliability and the demand impact of jointly normal distributed signals

The objective of this paper is to contribute to a better understanding of rational expectations equilibria. These equilibria emerge from demand decisions of investors who try to extract Information about future market prices from current ones. Therefore from an eeonomisfs perspective it seems crucial to quantify the impact of information on investors' demand decisions in a way that readily allows for economic interpretation. Unfortunately matrix algebra although widely used in normal distribution theory has its shortfalls with respect to this aim. That is why this paper pro-vides a different approach.
