Abstract
We describe a rational expectations model in which there is not only asymmetric information about payoffs but also asymmetric information about the preference, proportion and precision of private information of investors. We define this payoff-irrelevant risk as transaction risk, which is described by market state variables unrelated to payoffs. When derivative assets are introduced, the prices of the derivative assets can reveal information about transaction risk. Due to the informational role of derivative-asset prices, introducing derivative assets can increase social welfare and the price of the underlying asset even though no investors are trading in these derivative assets.
