Abstract
This paper studies the interaction between fiscal policy and bondholders against the backdrop of high sovereign debt levels. For our analysis, we investigate the case of Italy, a country that has dealt with high public debt levels for a long time, using a Bayesian structural VAR model. We extend a canonical three variable macro mode to include a bond market, consisting of a fiscal rule and a bond demand schedule for long-term government bonds. To identify the model in the presence of political uncertainty and forward-looking investors, we derive an external instrument for bond demand shocks from a novel news ticker data set. Our main results are threefold. First, the interaction between fiscal policy and bondholders’ expectations is critical for the evolution of prices. Fiscal policy reinforces contractionary monetary policy through sustained increases in primary surpluses and investors provide incentives for “passive” fiscal policy. Second, investors’ expectations matter for inflation, and we document a Fisherian response of inflation across all maturities in response to a bond demand shock. Third, domestic politics is critical in the determination of bondholders’ expectations and an increase in the perceived riskiness of sovereign debt increases inflation and thus complicates the task of controlling price growth.

Eine Hochfrequenzanalyse zur Abgrenzung von überlagernden Effekten am Beispiel des Ausfallrisikos italienischer Staatsanleihen

Abstract
Die wirtschaftliche Aktivität und das Ausfallrisiko staatlicher Schulden beeinflussen sich gegenseitig. Sinkt die wirtschaftliche Aktivität einer Volkswirtschaft, steigt wegen fallender Steuereinnahmen das Risiko, dass der Staat Zinszahlungen und Tilgungen auf Staatsanleihen nicht zurückzahlen kann. Umgekehrt kann das staatliche Ausfallrisiko seinerseits die wirtschaftliche Aktivität beeinflussen. Steigt das Ausfallrisiko, geraten Banken unter Druck, die Staatsanleihen in ihren Bilanzen führen, und reduzieren die Kreditvergabe an Unternehmen. In der Konsequenz sinkt die wirtschaftliche Aktivität. Dieser Beitrag nutzt hochfrequente News-Ticker-Daten zur Ableitung politischer Ereignisse und davon ausgelöster Fluktuationen im Staatsschuldenrisiko. Diese allein politisch bedingten Fluktuationen ermöglichen es, den Effekt des Staatsschuldenrisikos auf die wirtschaftliche Aktivität zu messen, ohne dass die Schätzung von der gegenläufigen Beziehung der Variablen beeinträchtigt wird. Das Vorgehen wird am Beispiel Italiens erläutert.

Ricardian Equivalence, Foreign Debt and Sovereign Default Risk

Abstract
We study the impact of sovereign solvency on the private-public savings offset. Using data on 80 economies for 1989–2018, we find robust evidence for a U-shaped pattern in the private-public savings offset in sovereign credit ratings. While the 1:1 savings offset is observed at intermediate levels of sovereign solvency, fiscal deficits are not offset by private savings at extremely low and high levels of sovereign solvency. Particularly, the U-shaped pattern is more pronounced for countries with high levels of foreign ownership of government debt. The U-shaped pattern is an emerging market phenomenon; additionally, it is confirmed when considering foreign currency rating and external public debt, but not for domestic currency rating and domestic public debt. For considerable foreign ownership of sovereign bonds, sovereign default constitutes a net wealth gain for domestic consumers.
