In this paper, we first study the static equilibrium of a a closed economy model in terms of dependence on national income and interest rate from the main factors namely the marginal propensity to consume, tax rate, investment rate and the rate of currency demand. In the second part, we study...

In this paper, we will continue the study of the dynamic equilibrium solutions in the purpose of investigating the dependence limits (potential output and interest rate limit). We find also an interesting linear relation between the potential output and interest rate limit.
