Abstract: We study optimal policy in an economy in which public debt is used as collateral or liquidity buffer. Issuing more public debt raises welfare by easing the underlying financial friction; but this easing lowers the liquidity premium and increases the government's cost of borrowing. These considerations, which are absent in the basic Ramsey paradigm, help pin down a unique, long-run level of public debt. They require a front-loaded tax response to government-spending shocks, instead of tax smoothing. And they explain why a financial recession, more than a traditional one, makes government borrowing cheaper, optimally supporting larger fiscal stimuli.
