Neimark-Sacker bifurcation for the discrete-delay Kaldor model

We consider a discrete-delay time, Kaldor non-linear business cycle model in income and capital. Given an investment function, resembling the one discussed by Rodano, we use the linear approximation analysis to state the local stability property and local bifurcations, in the parameter space. Finally, we will give some numerical examples to justify the theoretical results.business cycle; Neimark-Sacker bifurcation; discrete-delay time

Hopf bifurcation in a dynamic IS-LM model with time delay

In this paper we investigate the impact of delayed tax revenues on the fiscal policy out-comes. Choosing the delay as a bifurcation parameter we study the direction and the stability of the bifurcating periodic solutions. With respect to the delay we show when the system is stable. Some numerical examples are finally given for justifying the theoretical results.Comment: 13 pages, 12 figure
