The European Central Bank is unique in setting monetary policy for several sovereign states with heterogeneous debt levels and different maturity structures. The monetary-fiscal nexus is central to the functioning of the euro area. We focus on one particular aspect of that nexus, the effect the...

Advanced economies borrowed substantially during the Covid recession to fund their fiscal policy. The Covid recession differed from the Great Recession in that sovereign debt markets remained calm and spreads barely responded. We study the experience of Greece, the most extreme manifestation of...

This paper proposes a non-linear New Keynesian Phillips curve (Inv-L NK Phillips Curve) to explain the surge of inflation in the 2020s. Economic slack is measured as firms' job vacancies over the number of unemployed workers. After showing empirical evidence of statistically significant...

We develop a new class of general equilibrium models with partially unfunded debt to propose a fiscal theory of trend inflation. In response to business cycle shocks, the monetary authority controls inflation, and the fiscal authority stabilizes debt. However, the central bank accommodates...

Infrequent but turbulent overt sovereign defaults on domestic creditors are a "forgotten history" in Macroeconomics. We propose a heterogeneous-agents model in which the government chooses optimal debt and default on domestic and foreign creditors by balancing distributional incentives v. the...

Despite a formal 'no-bailout clause', we estimate significant net present value transfers from the European Union to Cyprus, Greece, Ireland, Portugal and Spain, ranging from roughly 0.5% (Ireland) to 43% (Greece) of 2011 output during the recent Eurozone crisis. We propose a model to analyze...

How will sovereign debt markets evolve in the 21st century? We survey how the literature has responded to the Eurozone debt crisis, placing "lessons learned" in historical perspective. The crisis featured: (i) the return of debt problems to advanced economies; (ii) a bank-sovereign "doom-loop"...

The `Excessive Deficit Procedure' of the Maastricht Treaty on Economic and Monetary Union proposes two fiscal convergence conditions for entry and continued membership in the EMU: 1) a country's overall budget deficit for each fiscal year must be equal to or below 3% of GDP, and 2) a country's...

What makes an asset a "safe asset"? We study a model where two countries each issue sovereign bonds to satisfy investors' safe asset demands. The countries differ in the float of their bonds and their resources/fundamentals available to rollover debts. A sovereign's debt is more likely to be...

The recent debt crises in Europe and the U.S. states feature similar sharp increases in spreads on government debt but also show important differences. In Europe, the crisis occurred at high government indebtedness levels and had spillovers to the private sector. In the United States, state...
