The analysis is restricted to bounded quantity and price paths that fulfill the necessary conditions for an open-loop Nash equilibrium. I show that there exists a symmetric steady state and that its stability depends on the degree of product differentiation. When moving from complements to perfect substitutes, the steady state is either a locally asymptotically unstable (spiral) source, a stable (spiral) sink or a saddle point. I further apply the Hopf bifurcation theorem and prove the existence of limit cycles, when passing from a stable to an unstable steady state. Lastly, I provide a numerical example and show that there exists a stable limit cycle.","lang":"eng"}],"user_id":"477","project":[{"_id":"7","grant_number":"160364472","name":"SFB 901 - A3: SFB 901 - Der Markt für Services: Anreize, Algorithmen, Implementation (Subproject A3)"},{"_id":"1","grant_number":"160364472","name":"SFB 901: SFB 901: On-The-Fly Computing - Individualisierte IT-Dienstleistungen in dynamischen Märkten "},{"_id":"2","name":"SFB 901 - A: SFB 901 - Project Area A"}],"type":"journal_article","title":"Dynamic Monopolistic Competition","author":[{"full_name":"Hoof, Simon","last_name":"Hoof","first_name":"Simon"}],"date_created":"2023-06-15T14:05:25Z","publication_identifier":{"issn":["1573-2878"]},"citation":{"short":"S.
