The paper utilizes duality theory to derive an exact representation of the core of a supermodular capacity for finite-state-space Choquet expected utility preferences. Using the dual representation we develop an algorithm that uses information on willingness to pay and willingness to sell to elicit a supermodular capacity in a finite number of iterations.
