Comments on Debt Dynamics
The present paper deals with the accumulation of public debt based on different kinds of non-linear models. The same problem is analysed here in three different models. In the first model difference between growth rate and interest rate depends lineary on the debt/GDP ratio and the budget deficit. In the second model version this connection was non-linear, so two kinds of economic policy could be applied. In the third version the growth rate as well as the interest rate are in close connection with the debt/GDP ratio, in this case a stable equilibrium or a saddle path could be shown up.
