This paper examines the implications of different monetary and fiscal policy rules in an economy characterized by Harrodian instability. We show that (i) a monetary rule along Taylor lines can be stabilizing for low debt ratios but becomes de-stabilizing if the debt ratio exceeds a certain...

The authors analyze the effects of government spending cuts on economic activity in an environment of severe fiscal strain, as reflected by a sizeable risk premium on government debt. Specifically, they consider a 'sovereign risk channel,' through which sovereign default risk spills over to the...

The initial government debt-to-GDP ratio and the government's commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation...

This paper builds a two-country Heterogenous Agents New Keynesian (HANK) model for the Euro Area (EA). The two countries differ in the degree of public indebtedness, i.e., the Periphery has a relatively higher public debt-output ratio vis-à-vis the Core. The model captures some key features of...

Societies often rely on simple rules to restrict the size and behavior of governments. When fiscal and monetary policies are conducted by a discretionary and profligate government, I find that revenue ceilings vastly outperform debt, deficit and monetary rules, both in effectiveness at curbing...

Fiscal policy and public debt may be required to maintain full employment and avoid secular stagnation. This conclusion emerges from a range of different models, including OLG specifications and stock-flow consistent (post-) Keynesian models. One of the determinants of the required long-run debt...

This paper makes three main points. Fiscal policy, first, may be needed in the long run to maintain full employment and avoid secular stagnation. If fiscal policy is used in this way, second, the long-run debt ratio depends (i) inversely on the rate of growth, (ii) inversely on government...

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...

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...

Governments can issue public debt for both good and bad reasons. The former include intertemporal tax smoothing, fiscal stimulus, and asset management. In contrast, the bad reasons, which generate higher indebtedness, are mainly associated with political cycles, rent capture, intergenerational...
