Abstract
This article studies an agent's valuation of the right to trade in a complete contingent claims market. The proposed measure generalizes the Pratt (1964) risk premium, which captures the willingness to pay to replace a given risky wealth prospect with an actuarially equivalent, nonrisky wealth. Specifically, we define ageneralized risk premium to be the willingness to pay to trade at going market prices. If state prices are actuarially fair, the Pratt premium is obtained as a special case. We derive several properties of this generalized premium and note its relationship to the option price of a public project under uncertainty.
