Research Topics, Overview of the research

• Research Topics

  nonlinear economic dynamics

• Overview of the research

  I have studied nonlinear economic dynamics by appealing to the bifurcation theory of dynamical syatem and the theory of Markov process. More concretely, I have obtained some results concerning the existence of sunspot equilibrium in continuous time models and the existence of periodic, chaotic and homoclinic solutions on equilibrium paths in various kinds of multisector growth models.
