In this paper, we propose to identify the dependence structure existing between the returns of equity and commodity futures and its evolution through the past 20 years. The key point is that we do not do not impose the dependence structure but let the data select it. To do so, we model the...

The theoretical determinants of maximum sustainable government debt are investigated using Diamond's overlapping-generations model. A level of debt is defined to be 'sustainable' if a steady state with non-degenerate values of economic variables exists. We show that a maximum sustainable level...

The fiscal gains from, and hence the political incentives for, an increase in the inflation rate of ten percentage points may be substantial: Swedish data from 1994 suggests an annual real flow of 3–4% of GDP, or a capitalized value of nearly 100% of GDP. These gains would have arisen mainly...

Our aim is to provide insights into some basic facts of US government debt management by introducing simple financial frictions in a Ramsey model of fiscal policy. We find that the share of short bonds in total U.S. debt is large, persistent, and highly correlated with total debt. A well known...

In the context of a sticky price DSGE model subject to government expenditure and preference shocks where governments issue only nominal non-contingent bonds we examine the implications for optimal inflation of changes in the level and average maturity of government debt. We analyse these...

We show how to model portfolio models in the presence of long bonds. Specifically we study optimal fiscal policy under incomplete markets where the government issues bonds of maturity N 1. Assuming the existence of long bonds introduces an additional intertemporal mechanism that makes taxes...

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...

Foreign exchange windfalls such as those from natural resource revenues change non-resource exports, imports, and the capital account. We study the balance between these responses and, using data on 41 resource exporters for 1970-2006, show that the response to a dollar of resource revenue is,...

This paper proposes a dynamic politico-economic theory of fiscal policy in a world comprising a set of small open economies, whose driving force is the intergenerational conflict over debt, taxes, and public goods. Subsequent generations of voters choose fiscal policy through repeated elections....

We analyse different forms of international debt mutualisation in a simple framework with a political distortion and (partial) default under adverse economic circumstances. One form is a debt repayment guarantee, which can be "unlimited" or "limited", i.e. only be invoked when the guarantee...
