Italian Abstract: Viene impostato il calcolo esplicito dei celeberrimi modelli di Kreps e Wilson (1982) e Milgrom e Roberts (1982) utilizzando funzioni lineari nel caso di una impresa monopolista pre-esistente e una potenziale entrante. Il modello calcola le strategie statiche, le strategie nei giochi ripetuti e nei giochi con informazione asimmetrica. In questi ultimi viene esplicitato anche il calcolo delle probabilità bayesiane a posteriori.

English Abstract: Explicit computations for the famous models by Kreps and Wilson (1982) and Milgrom and Roberts (1982) are presented, using linear functions in the case of the monopolist incumbent and a potential entrant. The model calculates the static equilibrium strategies, the strategies in repeated games and in games with asymmetric information, where the incumbent can cheat about being strong. In the latter explicit derivation of posterior Bayesian beliefs is shown.
