According to Pontryagin’s maximum principle, optimal solutions are concatenations of singular and bang arcs and exhibit the chattering or <jats:italic>Fuller</jats:italic> phenomenon, which is problematic for applications. To avoid chattering, we introduce a reduced model which is still biologically relevant and retains the important structural features of the original problem. Using a combination of analytical and numerical methods, we show that the singular arc is dominant in the studied DOCPs and exhibits the <jats:italic>turnpike</jats:italic> property.

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"}],"publication":"Journal of Optimization Theory and Applications","title":"Dynamic Monopolistic Competition","date_created":"2023-06-15T14:05:25Z","publisher":"Springer","year":"2021","issue":"2","quality_controlled":"1"},{"publisher":"Springer Science and Business Media LLC","date_updated":"2024-05-11T11:52:17Z","date_created":"2024-05-11T11:25:18Z","author":[{"first_name":"Rashed","full_name":"Khanjani Shiraz, Rashed","last_name":"Khanjani Shiraz"},{"first_name":"Madjid","last_name":"Tavana","full_name":"Tavana, Madjid","id":"31858"},{"first_name":"Debora","last_name":"Di Caprio","full_name":"Di Caprio, Debora"},{"first_name":"Hirofumi","full_name":"Fukuyama, Hirofumi","last_name":"Fukuyama"}],"volume":170,"title":"Solving Geometric Programming Problems with Normal, Linear and Zigzag Uncertainty Distributions","doi":"10.1007/s10957-015-0857-y","publication_status":"published","publication_identifier":{"issn":["0022-3239","1573-2878"]},"issue":"1","year":"2016","citation":{"ama":"Khanjani Shiraz R, Tavana M, Di Caprio D, Fukuyama H.
