corresponding payoffs constitute Nash equilibrium. Stated simply‚ Amy and Phil are in Nash equilibrium if Amy is making the best decision she can‚ taking into account Phil’s decision‚ and Phil is making the best decision he can‚ taking into account Amy’s decision. Likewise‚ a group of players is in Nash equilibrium if each one is making the best decision that he or she can‚ taking into account the decisions of the others. However‚ Nash equilibrium does not necessarily mean the best payoff for all the

reflect the decision maker’s perspective and attitude toward risk. Each payoff is assigned a utility value. Higher payoffs get larger utility value. The optimal decision is the one that maximizes the expected utility. Determining Utility Values The technique provides an insightful look into the amount of risk the decision maker is willing to take. The concept is based on the decision maker’s preference to taking a sure payoff versus participating in a lottery. Determining Utility Values Indifference

Asian Options have payoffs that depend on the average price of the underlying asset during at least some portion of the life of the option. • Barrier Options have payoffs that depend both on the asset’s price at expiration and on whether the underlying asset’s price has crossed through some barrier. If the asset’s price crosses the barrier the option might automatically expire. Or if the asset’s price does not cross the barrier the option may not pay. • Lookback Options have payoffs linked to the

by changing only their own strategy unilaterally. If each player has chosen a strategy and no player can benefit by changing strategies while the other players keep theirs unchanged‚ then the current set of strategy choices and the corresponding payoffs constitute Nash equilibrium. 1.1 John Forbes Nash Jr. John Forbes Nash‚ Jr. is an American mathematician who was born on June 13‚ 1928.
