In this paper, we propose a model of mutual interactions between the economically active population and the economic growth. Our principal goal is to introduce a delayed equation of the active population evolution. The time delay, resulting from the recruitment processes, is incorporated in the effective labor demand. The dynamics are studied in terms of local stability and of the description of the Hopf bifurcation, is proven to exist as the delay (taken as a parameter of bifurcation) cross some critical value. Some numerical simulations are given to illustrate our theoretical results. Additionally we conclude with some remarks.
