The double scroll chaotic attractor in the dynamics of a fixed-price IS-LM model

Biographical notes: Giovanni Bella’s actual research is inserted in the literature of environmental economics, with particular attention to the different typologies of economic equilibrium that emerge when introducing an environmental variable. His recent interest regards the application of search theory to the problem of pollution control, while particular attention is reserved to the problem of indeterminateness of the equilibrium solutions, and the consequent problems of bifurcation and chaos in the steady state trajectories. This also implies the study of the dynamic problems that characterise the economic systems in the transition towards a sustainable development. A deep analysis of the environmental Kuznets curve hypothesis within OECD countries is also analysed. A further field of analysis regards the application of the predator-prey theory, and its impact on the exploitation of the natural resources and the mass tourism concerns.
