The purpose of this dissertation is to study the optimal response of salesadvertising models for duopolies using modern optimization software (JModelica.org and JuMP). Specifically, the models adopted were the Vidale-Wolfe-Deal and the Three Populations, a Lotka-Volterra type model. Duopoly analysis is split in two parts: one that solves an optimal control problem with the objective of maximizing the net profit of both firms in one-shot, referred to as simultaneous co-operation, and the other that places the two firms as opponents in a sequential game, each with the individual goal of maximizing net profit on its turn, referred to as sequential competition. The contributions of this dissertation are: providing a stability analysis for the Vidale-Wolfe-Deal model, which shows that any control attaining final constant positive values leads to a stable equilibrium of market shares, proposing a duopolistic version of the Three Populations model, and, lastly, proposing and solving a sequential game based on Leader-Follower iteration for the Vidale-Wolfe-Deal model.
