We build a tractable stylized model of external sovereign debt and endogenous international interest rates. In corrupt economies with rent-seeking groups stealing public resources, a politico-economic equilibrium is characterized by permanent fiscal impatience which leads to excessive issuing of...

Large and growing levels of public debt in the United States, United Kingdom, Japan and the Euro Area raise new interest in the cross-country effects of a large open economy's deficits. We consider a dynamic optimizing model with costly tax collection and exogenously given public spending and...

We welfare rank various tax-spending policies. The setup is a New Keynesian model of a semi-small open economy featuring sovereign risk premia and loss of monetary policy independence. The model is calibrated to match data from the Italian economy 2001-2011. We compute various optimized...

We study the desirability of limits on the public debt and of political turnover in an economy where incumbents have an incentive to set public expenditures above the socially optimal level due to rent-seeking motives. Parties alternate in office and cannot commit to future policies, but they...

The implications of high indebtedness for strategic tax setting in internationally integrated capital markets have found little attention so far. We analyze when and how changes in initial debt levels affect the distribution of economic activity across space. When public borrowing is...

In this paper we analyse debt stabilization in a monetary union that features endogenous risk premia. In particular, we analyse debt stabilization in two diametrically opposed regimes. In the first regime, the “national fiscal discipline regime”, financial markets impose sovereign risk...

We consider an economy where competing political parties alternate in office. Due to rent-seeking motives, incumbents have an incentive to set public expenditures above the socially optimum level. Parties cannot commit to future policies, but they can forge a political compromise where each...

We explore the benefits of intergenerational risk-sharing through both private funded pensions and via the public debt. We use a multi-period overlapping generations model with a PAYG pension pillar, a funded pension pillar and a government. Shocks are smoothed via the public debt and variations...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...
