Crisis curves in nonlinear business cycles

Intermittent behavior of economic dynamics is studied by a nonlinear model of business cycles when two of its control parameters, amplitude and frequency of a periodic exogenous driving force, are changed. This study points out how similar wanted situations may be reached by changing any of both parameters, and it gives a deeper understanding of what happens in actual economic data when some control parameters are changed at the same time.

► Nonlinear models of business cycles permit the study of intermittent behavior on economic dynamics.
► We study the simultaneous influence of two control parameters.
► The 2D parametric study permits to locate several bifurcation structures and the boundary crisis in economics models.
► Similar wanted situations can be reached by changing any of the two parameters, allowing to control the system.
