First, consider the prisoner’s dilemma.
Another interesting observation to make is that (-5, -5) which is the only Non-Pareto optimal outcome in the game is also the dominant strategy every player is expected to play, making it the Nash equilibrium. This is why the prisoner’s dilemma is A Nash equilibrium (NE) (5, 6) is a strategic profile in which each player’s strategy is a best response to the strategies chosen by the other players. The concept of NE is a standard game-theoretic formalization of noncooperative self-interest on the part of all players. A pure Nash equilibrium (PNE) is a NE and a pure strategic profile. Which means that the Nash Equilibrium solution is for a player to always Defect. However, the Pareto efficient outcome would be for neither to Defect, and both to Cooperate.
They provide a way to identify reasonable outcomes when an easy argument based on domination (like in the prisoner’s dilemma, see lecture 2) is not available. Nash Equilibrium & Pareto Optimality. One of the features of a Nash equilibrium is that in general, it does not correspond to a socially optimal outcome.

But, on the other hand, there are particular games in which Nash equilibria turn out to be Pareto-optimal [1], [4], [6], [18], [20]. Which means that the Nash Equilibrium solution is for a player to always Defect.

Interchange Fees in ”Equilibrium Vertical Foreclosure”. American. I detta fall är situationen (A1, B1) Pareto optimal. Nash Equilibrium är en uppsättning rörelser där ingen vill göra något annorlunda efter en fait accompli. 'Pareto optimality' is an efficiency concept. So no state will be Pareto Optimal if, at least one of the players can get more payoff without decreasing the payoff of any other player. There are many many examples of Nash Equilibria which are not pareto optimal.
Solving each FOC equation for −λand rearranging we see
A Nash equilibrium is what's strategically feasible. A Pareto optimal solution is what's efficient.

In game theory, the Nash equilibrium, named after the mathematician John Forbes Nash Jr., is the most common way to define the solution of a non-cooperative game involving two or more players. In a Nash equilibrium, each player is assumed to know the equilibrium strategies of the other players and no player has anything to gain by changing only their own strategy. The principle of Nash equilibrium dates back to the time of Cournot, who applied it to competing firms choosing outputs.

This paper is organized as follows. Section 2 presents a detailed literature survey of spectrum sensing techniques for PA in a MIMO network. Pareto optimality Nash equilibrium Always at least one Pareto optimal profile in which the strategies are pure . Nau: Game Theory 4 5, For a given system, the Pareto frontier or Pareto set is the set of parameterizations (allocations) that are all Pareto efficient.

By contrast, we prove a previously conjectured result: Every finite normal-form game of complete information and common knowledge has at least one Pareto-optimal nonmyopic equilibrium (NME) in pure strategies, which we define and illustrate. The outcome it gives, which depends on where play starts, may or may not coincide with that given by a Nash equilibrium. Nash equilibria can be used to predict the outcome of finite games, whenever such equilibrium exists.

Pareto optimality Nash equilibrium Always at least one Pareto optimal profile in which the strategies are pure . Nau: Game Theory 4 5, For a given system, the Pareto frontier or Pareto set is the set of parameterizations (allocations) that are all Pareto efficient. Finding Pareto frontiers is particularly useful in engineering. By yielding all of the potentially optimal solutions, a designer can make focused tradeoffs within this constrained set of parameters, rather than needing to consider the full ranges of parameters.
