We study the Ramsey policy problem in an economy in which firms face a collateral constraint. Issuing more public debt alleviates this friction by increasing the aggregate quantity of collateral. In so doing, however, the issuance of more debt also raises interest rates, which in turn increases...

The textbook optimal policy response to an increase in government debt is simple—monetary policy should actively target inflation, and fiscal policy should smooth taxes while ensuring debt sustainability. Such policy prescriptions presuppose an ability to commit. Without that ability, the...

Optimal debt management can be thought of in three stages. First, if taxes are lump sum and the other conditions for Ricardian equivalence hold, then the division of government financing between debt and taxes is irrelevant, and the whole level of public debt is indeterminate from an optimal-tax...

Under free capital mobility, confidence crises can result in devaluations even when fixed exchange rates are viable, if fiscal authorities can obtain temporary money financing. During a crisis, domestic interest rates increase reflecting the expected devaluation. Rather than selling debt at...

A traditional explanation for why sovereign governments repay debts is that they want to keep good reputations so they can easily borrow more. Bulow and Rogoff show that this argument is invalid under two conditions: (i) there is a single debt relationship, and (ii) regardless of their past...

A tax-smoothing objective is used to assess the optimal consumption of public debt with respect to maturity and contingencies. This objective motivates the government to make its debt payout contingent on the levels of public outlay and the tax base. If these contingencies are present, but asset...

In an economy with a debt overhang, investment depends on expected tax rates. On the other hand, expected tax rates depend on the debt's face value. Therefore investment depends on the face value of debt. I show that this may lead to a positive or negative association between debt and investment...

What determines the sustainability of sovereign debt? We develop a model where myopic governments seek popularity but can nevertheless commit credibly to service external debt. They do not default when debt is low because they would lose access to debt markets and be forced to reduce spending;...

A new aggregation scheme used to measure the sources of fiscal financing of indebted countries suggests that there was a fundamental improvement in the seniority of domestic debt at the expense of foreign bank debt during the late 1980s. We argue that this was the revenue maximizing response of...

This paper examines the effect that the coexistence of small and large banks, with different interests in the international market, has on the debt renegotiation process. Making use of a reputational model, we argue that the presence of small banks implies that debtor countries have a harder...
