How costly are sovereign debt crises? In this paper we study output losses during sovereign default and debt renegotiation episodes since 1980. In contrast to previous work, we account for the severity of default and not only for its occurrence. Specifically, we distinguish between "hard" and...

What is an optimal or a sustainable external debt - for a country, region or sector? How should one monitor and evaluate debt to preclude a crisis? We use stochastic optimal control/dynamic programming to derive an optimal debt. The deviation of the actual from the optimal will serve as a...

Rising public debt everywhere has raised the question of how to reduce debt again in the future. High public debt also seems to be an impediment for the exit of central banks from ultra-low interest rates and quantitative easing. Historical precedents and proposals have included austerity,...

One of the main functions of public debt is to smooth taxes and spending over time. In the Covid crisis, the Maastricht deficit restrictions were temporarily suspended to allow for large temporary deficits. As recovery sets in, countries are confronted with the task of consolidating the Covid...

This paper investigates the long-run effects of public debt and inflation on economic growth. Our contribution is both theoretical and empirical. On the theoretical side, we develop a cross-sectionally augmented distributed lag (CS-DL) approach to the estimation of long-run effects in dynamic...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

In a monetary union, the interaction between several governments and a single central bank is plagued by several sources of deficit bias, including common pool problems. Each government has strong preferences over local spending and taxation but suffers only part of the costs of union-wide...

This paper develops a dynamic two-country neoclassical stochastic growth model with incomplete markets. Short-term credit flows can be excessive and reverse suddenly. The equilibrium outcome is constrained inefficient due to pecuniary externalities. First, an undercapitalized country borrows too...

We analyze optimal monetary policy under commitment in an economy with uninsurable idiosyncratic risk, long-term nominal bonds and costly inflation. Our model features two transmission channels of monetary policy: a Fisher channel, arising from the impact of inflation on the initial price of...

This paper empirically studies whether it pays off (in terms of economic growth) to fulfill the convergence criteria on the public budget and participation in the Euro-zone. The analysis is based on data of European economies with a special focus on twelve Euro-zone members and a control group...
