   The private capital market clearing equation {eq}`EqMarkClr_KtKdKf` is stationarized by dividing both sides by $e^{g_y t}\tilde{N}_t$, as is the expression for excess demand at the world interest rate {eq}`EqMarkClr_ExDemK` and the exogenous expression for foreign private capital flows {eq}`EqMarkClr_zetaK`.
