Iterative deletion and Nash equilibria in a 3 players game
I was waked with finding all the Pure Nash Equilibrium in this game. After using the "circle the best response" method of finding each players rational choices it seems as though there is no Nash Equilibrium. That appear to only be points at which…

Signaling Game: Beer and Quiche Payoffs and Extensive Form Representation
I am working on a signaling game scenario named "Beer and Quiche" and need some assistance with understanding the payoffs and representing the game in an extensive form.
In this game, there are two types of senders: type 1 ("coward") with a…

Nash Equilibria in a Game with Three Firms and a Shared Resource
I’m trying to understand the Nash equilibria in a game involving three firms that use water from a shared lake. Each firm can choose to purify the water before returning it to the lake or not purify it (and therefore pollute the lake). The cost of…

How to derive a Nash equilibrium pure strategy in a linear Cournot Model
Suppose there are $N$ firms each with the same positive marginal cost $c$. How would I go about finding a pure strategy Nash Equilibrium for the firms? Suppose the Inverse Demand curve is defined: $p=a-Q$ with $Q$ being the market output.
