Contrasting with the 1929 great crisis, authorities intervened forcefully in 2008 to stop the disintegration of the financial system. Governments and central banks then sought to revise the prudential regulation in depth. It would be optimistic, however, to believe that prudential measures,...

This paper argues that in Euro-area economies, where the ECB cannot bail-out …nancially distressed governments, the …scal multiplier is adversely affected by the amount of public debt. A regression model on a panel of 26 EU countries over the period 1996-2011 shows that a 10 percentage point...

Barro's model is an AK model, and there cannot be dynamic inefficiency since the social yield of the capital is higher than the growth rate. But it may be that the private yield and thus the interest rate are lower than the growth rate. One can thus have a Ponzi game and the government can allow...

This paper studies the inflationary implications of interest bearing regional debt in a monetary union. Is this debt simply backed by future taxation with non inflationary consequences ? Or will the circulation of region debt induce monetization by a central bank ? We argue here that both...

This paper assesses the long-run optimal level of public debt in a framework where aggregate fluctuations are taken into account. Households are subject to both aggregate and idiosyncratic shocks and the market structure prevents them from perfectly insuring against risk. We find that the...

This paper analyses the effect of transitory increases in government spending when public debt is used as liquidity by the private sector. Aggregate shocks are introduced into an incomplete-market economy where heterogenous, infinitely-lived households face occasionally binding borrowing...

This article analyzes the consequences on capital accumulation and environmental quality of environmental policies financed by public debt. A public sector of pollution abatement is financed by a tax and/or public debt. We show that if the initial capital stock is high enough, the economy...

We introduce public debt in a Ramsey model with heterogenous agents and a public spending externality affecting utility which is financed by income tax and public debt. We show that public debt considered as a fixed portion of GDP can have a stabilizing or destabilizing effect depending on some...

Some recent evidence on government finance statistics of European countries suggests that countries with public debt issues also show a low tax revenue-GDP ratio. In this paper we develop a small open economy model of endogenous growth in which the engine of growth is public spending. We assume...

Imposing some constraints on public debt is often justified regarding sustainability and stability issues. This is especially the case when the ratio of public debt over GDP is restricted to be constant. Using a Ramsey model, we show that such a constraint can however be a fundamental source of...
