We use a sovereign default model to study the effects of introducing limits to the decision-making capabilities of governments-fiscal rules. We show that optimal limits to the debt level vary greatly across parameterizations of the model that deliver different levels of debt tolerance. In...

We quantify gains from introducing non-defaultable debt as a limited additional financing option into amodel of equilibrium sovereign risk. We find that, for an initial (defaultable) sovereign debt level equalto 66 percent of trend aggregate income and a sovereign spread of 2.9 percent,...

We study gains from introducing a common numerical fiscal rule in a "Union" of model economies facing sovereign default risk. We show that among economies in the Union, there is significant disagreement about the common debt limit the Union should implement: the limit preferred by some economies...

As a response to economic crises triggered by COVID-19, sovereign debt standstill proposals emphasize debt payment suspensions without haircuts on the face value of debt obligations. We quantify the effects of standstills using a standard default model. We find that a one-year standstill...

Using a quantitative sovereign default model, we characterize constrained efficient borrowing by a Ramsey government that commits to income-history-contingent borrowing paths taking as given ex-post optimal future default decisions. The Ramsey government improves upon the Markov government...

We study the sovereign debt duration chosen by the government in the context of a standard model of sovereign default. The government balances off increasing the duration of its debt to mitigate rollover risk and lowering duration to mitigate the debt dilution problem. We present two main...
