With this paper, our objective is to empirically study public debt sustainability by estimating a fiscal reaction function where the primary balance relative to GDP is assumed to be a function of the public debt to GDP ratio of the previous year and of other macroeconomic variables. In...

Is there a role for debt beyond curing overaccumulation of capital? Does dynamic efficiency and the infeasibility of debt Ponzi schemes eliminate any Pareto-improving role for a government in a competitive economy with complete markets? Is there an optimal maturity structure of public debt?...

We provide a systematic analysis of fiscal consolidation in a medium-scale dynamic general equilibrium model. Our results show that the choice of the consolidation instrument is very important, not only with respect to the short- and long-run output effects of the different consolidation...

The COVID-19 crisis has caused public debt to increase dramatically, which is why the German and European fiscal rules are currently suspended. In addition to the new assessment of the fiscal costs at low interest rates (r g), the discussion on the reintroduction of fiscal rules in Germany and...

We analyse the international transmission of interest rates by focusing on the role of the accumulation of international reserves and on the financing of sovereign debt. An increase in foreign exchange reserves is expected to moderate the influence of U.S. interest rates. However, a high level...

In times when elevated government debt raises concerns about dimmer global growth prospects, we ask: How can the government provide incentives for innovation in a fiscally sustainable way? We address this question by examining the Ramsey problem of finding optimal tax and subsidy schemes in a...

We provide a systematic analysis of fiscal consolidation in a dynamic general equilibrium model with a detailed government sector and a share of credit-constrained households. We simulate permanent cuts in government consumption, government investment, and transfer payments as well as permanent...

This paper studies the effectiveness of Euro Area (EA) fiscal policy, during the recent financial crisis, using an estimated New Keynesian model with a bank. A key dimension of policy in the crisis was massive government support for banks - that dimension has so far received little attention in...

The current fiscal imbalances and fragilities in the Southern and Eastern Mediterranean countries (SEMC) are the result of decades of instability, but have become more visible since 2008, when a combination of adverse economic and political shocks (the global and European financial crises, Arab...

This paper uses a multi region DSGE model with collateral constrained households and residential investment to examine the effectiveness of fiscal policy stimulus measures in a credit crisis. The paper explores alternative scenarios which differ by the type of budgetary measure, its length, the...
