Abstract
This investigation aims at developing a methodology to establish stability
and bifurcation dynamics generated by a class of delayed economic model, whose
state variable is described by the scalar delay differential equation of the form . At appropriate
parameter values, linear stability and Hopf bifurcation including its direction and
stability of the economic model are obtained. The main tools to obtain our results
are the normal form method and the center manifold theory introduced by Hassard.
Simulations show that the theoretically predicted values are in excellent agreement
with the numerically observed behavior. Our results extend and complement some
earlier publications.
