# How do you find Nash equilibrium with best response?

## How do you find Nash equilibrium with best response?

- Find the firms’ best response functions. To find the best response of firm 1 to any action a2 of firm 2, fix a2 and solve. maxa1a1(c + a2 a1).
- A Nash equilibrium is a pair (a1*,a2*) such that a1* = b1(a2*) and a2* = b2(a1*). Thus a Nash equilibrium is a solution of the equations a1* = (c + a2*)/2. a2* = (c + a1*)/2.

## How do you determine the best response function?

To find best response function of firm 1, look at its payoff as a function of its output, given output of firm 2. Any price greater than p2 is a best response to p2: B1(p2) = {p1 : p1 > p2}. Note: a price between p2 and c is a best response!

### Is best response the same as Nash equilibrium?

The concept of a best response is central to John Nash’s best-known contribution, the Nash equilibrium, the point at which each player in a game has selected the best response (or one of the best responses) to the other players’ strategies (Nash 1950).

**Is the best outcome in a game always a Nash equilibrium?**

Unlike dominant strategy, the Nash equilibrium doesn’t always lead to the most optimal outcome, it just means that an individual chooses the best strategy based on the information they have.

**What’s the difference between dominant strategy and Nash equilibrium?**

According to game theory, the dominant strategy is the optimal move for an individual regardless of how other players act. A Nash equilibrium describes the optimal state of the game where both players make optimal moves but now consider the moves of their opponent.
