(1) ___________ exists when one party to a transaction changes his behavior in a way that is hidden from or costly to the other party. For example, once we are covered by insurance, we may take greater risks, knowing the insurance will cover our mistakes.  In this case, asymmetric information exists (2) ______________ an exchange.

We refer to a “game” every time we consider a scenario in which the action of one agent (either individual, firm, or government) affects other agents’ well-being. Elements of the game: (1) Player: The set of individuals, firms, governments or countries, that interact with one another. We consider games with 2 or more players. (2) Strategy: A complete plan describing which actions a player chooses in each possible situation (contingency). (3) Payoff: What every player obtains under each possible strategy path. Consider 2 people (i.e., Bob and Nathan) who are arrested by the police and are placed in different cells. They cannot communicate with each other. The police separately offer to each of them the deal represented in the following matrix (where positive values indicate the amount of fine that causes disutility): The “Nash Equilibrium (NE)”, named after Nash (1950) builds on the notion that every player finds her “best response” to each of her rivals’ strategies. A strategy profile is a NE if every player chooses the best response to her rivals’ strategies. The strategic profile of two Nash Equilibrium (NE) in the above game are: The first Nash Equilibrium (NE):  (Nathan does not confess and pays $2000 as a fine and Bob does not confess and pays $2000 as a fine) — case 1. The second Nash Equilibrium (NE): (Nathan confesses and pays $3000 and Bob confesses and pays $3000 as a fine) — case 4. Based on the above results, Two individuals (i.e., Nathan and Bobs) , charged with jointly committing a crime, would be best off in this setting if (1) _________________ however, individually rational behavior leads to a jointly inefficient outcome where (2) ______________ The name of this well-known game in game theory is prisoner’s dilemma.
