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...

This paper finds optimal fiscal rule parameter values and measures the effects of imposing fiscal rules using a default model calibrated to an economy that in the absence of a fiscal rule pays a significant sovereign default premium. The paper also studies the case in which the 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...

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...

We propose a modification to a baseline sovereign default framework that allows us to quantify the importance of debt dilution in accounting for the level and volatility of the interest rate spread paid by sovereigns. We measure the effects of debt dilution by comparing the simulations of the...

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