Our aim is to provide insights into some basic facts of US government debt management by introducing simple financial frictions in a Ramsey model of fiscal policy. We find that the share of short bonds in total U.S. debt is large, persistent, and highly correlated with total debt. A well known...

We show how to model portfolio models in the presence of long bonds. Specifically we study optimal fiscal policy under incomplete markets where the government issues bonds of maturity N 1. Assuming the existence of long bonds introduces an additional intertemporal mechanism that makes taxes...

Using a stochastic growth model we derive analytic expressions for optimal labour and capital tax rates under both complete and incomplete markets. We find taxes are driven by two factors reflecting : (a) Ramsey efficiency considerations and (b) the financing needs of the government which vary...
