The variable pt is referred to as the conditional risk premium and corresponds to the conditional expectation of the payoff. As Equation (10.10) suggests, one approach to learning about risk premia is to build a forecasting model for the payoffs to the carry trade. An approximation to the mathematical expectation in Equation (10.10) is implicit in any forecasting model. Therefore, model forecasts correspond to estimates of the risk premium (Fama, 1984).

Consider an example of an individual-currency carry trade in which the domestic interest rate exceeds the foreign interest rate, that is, images, or, equivalently that the foreign currency is at a forward premium: Ft > St. Assume that the carry trader sells units, rather than ...
