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...

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 analyzes the optimal level of public debt when taxes are used not only for funding public expenditures but also for correcting externalities from climate change. Taking into account externalities implies that the optimal policy deviates from tax smoothing. Provided cumulative marginal...

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...

Using an OLG model with skill uncertainty and private savings, we investigate whether an optimally designed set of public pension transfers can usefully supplement a nonlinear labor income tax as a welfare-enhancing policy instrument. We consider a Mirrleesian setting where agents' skills are...

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...

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...

This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the...

Occasional crises have been shown to be part of growth enhancing mechanism (see Rancière, Tornell and Westermann, 2008). In this paper, we document that neither the stereotypical case study of India vs. Thailand, nor the benchmark growth-regression in this earlier research support this result...
