Two puzzling observations have motivated this paper: First, the standard paradigm of optimal fiscal policy, following Lucas & Stokey (1983), assumes counterfactually that public debt is held in state-contingent securities. Is the existing theory as irrelevant as it is silent about fiscal policy...

The public sector, in carrying out its operations, often incurs foreign currency denominated liabilities and, as such, is exposed to exchange rate fluctuations that could affect the value of public debt to GDP ratios over time. This paper shows that converting foreign currency denominated flows...

We offer a new methodology for the assessment of public debt sustainability in a stochastic economy when sovereign default taken into account. The default threshold differs from the no-Ponzi condition and depends on the post-default debt recovery rule. We distinguish sustainability and...

This paper discusses an alternative route to a balanced budget, namely through debt control. Two models are compared: the debt brake which has been used in Switzerland since 2003 and the debt limitation model proposed by Compact for America. The paper concludes that the former, while apparently...

There have been many attempts at solving the problem of determining the “fundamental value” of the credit spread of a government bond. This is particularly important in the case of Eurozone, where the ECB intervention on the government bonds' market is allowed only if the “spread” paid...

How important is the planning horizon of households for the effects of fiscal plans? We address this question through the lens of a New-Keynesian model where households are boundedly rational and plan over a finite number of periods. We show that the planning horizon affects the medium-run...

Why do countries tend to repay their domestic and external debt, even though the legal enforcement of the sovereign debt contract is limited? Contrary to conventional wisdom, we argue that temporary market exclusion after default is costly. When the domestic financial market is characterized by...

A windfall of natural resource revenue (or foreign aid) faces government with choices of how to manage public debt, investment, and the distribution of funds for consumption, particularly if the windfall is both anticipated and temporary. We show that the permanent income hypothesis prescription...

We analyze fiscal consolidations using a New-Keynesian model where agents have finite planning horizons and are uncertain about the future state of the economy. Both consumers and firms are infinitely lived, but only plan and form expectations up to a finite number of periods into the future....
