We introduce soft budget constraint and stop-go policy into a stable two-sector AK macro-model. As the extended model does not have any fixed point, we use computer-simulation to examine the dynamic behaviour of the model. We show that depending on the starting position and the parameter values,...

The paper studies the characteristics of the evolution over time of modal split for a transport system in which various modes compete with each other and face the freight flow increase in different ways. It is shown that the modal split evolution is constituted by a sequence of time periods, in...

Activities of genes are controlled in a combinatorial fashion by the concentrations of chemical called transcription factors. We model this type of network by piecewise linear differential equations formed by embedding a logical switching network in a differential equation. We generate...
