We provide a comprehensive analysis of the determinants of trading in the sovereign credit default swaps (CDS) market, using weekly data for single-name sovereign CDS from October 2008 to September 2015. We describe the anatomy of the sovereign CDS market, derive a law of motion for gross...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore crosscountry spillovers of tax...

Europe's debt crisis casts doubt on the effectiveness of fiscal austerity in highly-integrated economies. Closed-economy models overestimate its effectiveness, because they underestimate tax-base elasticities and ignore cross-country tax externalities. In contrast, we study tax responses to debt...

The COVID-19 pandemic is unlike any other crisis that we have experienced in that it hit all economies in the world at the same time, compromising the risk sharing ability of nations. At the onset of the pandemic, the World Bank (WB) and the International Monetary Fund (IMF) jointly pledged 1.16...

We introduce a novel database on sovereign defaults that involve public debt instruments governed by domestic law. By systematically reviewing a large number of sources, we identify 134 default and restructuring events of domestic debt instruments, in 52 countries from 1980 to 2018. Domestic-law...

This paper surveys the literature on sovereign debt from the perspective of understanding how sovereign debt differs from privately issue debt, and why sovereign debt is deemed safe in some countries but risky in others. The answers relate to the unique power of the sovereign. One the one hand,...

This paper presents an overview of the Ararat Fiscal Strategy Model (AFSM), which is a structural, New-Keynesian, DSGE, small open economy model with a rich fiscal block that includes several expenditure and revenue instruments, and types of debt. The AFSM is now a formal part of the Ministry of...

We estimate various panel fiscal reaction functions, including those of the main categories of general government revenue and expenditure for the 12 Euro area member states over the 1970-2013 period. We find that in the peripheral countries where sovereign bond yields decreased sharply in the...

This paper uses a risk-management approach to re-profile the sovereign debt of countries facing debt crises. Using scenario analysis we develop a risk measure of the sovereign's debt -- Conditional Debt-at-Risk -- and an optimization model is used to trace risk profiles that tradeoff expected...

We develop models for portfolio diversification in the sovereign credit default swap (CDS) markets and show that, despite literature findings that sovereign CDS spreads are affected by global factors, there is sufficient idiosyncratic risk to be diversified away. However, we identify regime...
