In the discrete-time new-Keynesian model with public debt, Ramsey optimal policy eliminates the indeterminacy of simple-rules multiple equilibria between the fiscal theory of the price level versus new-Keynesian versus an unpleasant equilibrium. If public debt volatility is taken into account...

This paper shows that debt-financed fiscal multipliers vary depending on the maturity of debt issued to finance spending. Utilizing state-dependent SVAR models and local projections for post-war US data, we show that a fiscal expansion financed with short term debt increases output more than one...

This paper proposes a methodology to price bonds jointly issued by a group of countries—called Eurobonds in the euro-area context. We consider two types of bonds: the first is backed by several and joint (SJG) guarantees, the second features several but not joint (SNJG) guarantees. A crucial...

Exploiting information contained in the term-structure of sovereign credit spreads, we estimate time-varying fiscal limits – defined as the maximum outstanding debt that can credibly be covered by future primary budget surpluses. Our approach is based on a novel sovereign credit risk model...

Debt-financed fiscal stimulus programmes directly stimulate aggregate demand through government expenditure or tax cuts, but their effectiveness is highly dependent on direct crowding out of private sector expenditure, spillover effects to the private sector through a higher risk premium on...

Governments around the world have gone on a massive fiscal expansion in response to the Covid crisis, increasing government debt to levels not seen in 75 years. How will this debt be repaid? What role do conventional and unconventional monetary policy play? We investigate debt sustainability in...

In this paper, I demonstrate that an indicator which is commonly used to assess the long-term fiscal sustainability of public finances in EU member states (“S2”) is also defined if government borrowing rates are assumed to be permanently lower than the growth rate of GDP. I illustrate this...

We apply non-linear error-correction models to the empirical testing of the sustainability of the government's intertemporal budget constraint. Our empirical analysis, based on Italy, shows that the Italian government is meeting its intertemporal budget constraint, in spite of the high levels of...
