A three-player normal form game with two strategies per player. 7 7. comments. Game Tree between the Spammer and the Defender Model definition. This game has nine Nash equilibria, which is the maximal number of regular Nash equilibria possible for a game of this size. If you are using a Mac, you will already have Python installed. (hint: set up the game with two players, each of which can undertake low or high shing activity). The classical Stackelberg game (Stackelberg 1934) models competition in a duopoly market composed of one leader and one follower. Back Matter. Stackelberg Model of Duopoly Stackelberg Duopoly Suppose that two rms (Firm 1 and Firm 2) face an industry demand P = 150 Q where Q = q 1 + q 2 is the total industry output. The situation can be modeled as a Stackelberg game, i.e. equilibria which are incompletely mixed, and a continuum of completely mixed equilibria. I know how to solve Stackelberg game using backward induction but have no idea about bayesian. I am trying to calibrate a stackelberg game, solved by backward induction method. It should print 2.

Firms have to compete by choosing the amount of output Q1 and Q2 to produce, but one of the two firms goes first. 3.3. Learn more. Subgame-Perfect Nash Equilibrium. PDF. Clempner and Poznyak described a Stackelberg security game that expresses a strategic game in which the defenders cooperate, and attackers do the opposite (do not cooperate). Although the numerical techniques should be those indicated in the Programme Structure, the economic topics may be adapted to the interest of the audience, and the aim is to have economic examples also when presenting the basics of Python.
