We develop a sovereign debt model with offcial and private creditors where default risk depends on both the level and the composition of liabilities. Higher exposure to offcial lenders improves incentives to repay but carries extra costs, such as reduced ex-post flexibility. The model implies...

We shed light on the function, properties and optimal size of austerity using the standard sovereign debt model augmented to include incomplete information about credit risk. Austerity is defined as the shortfall of consumption from the level desired by a country and supported by its repayment...

We propose a theory of tax centralization and inter governmental grants in politico-economic equilibrium. The cost of taxation differs across levels of government because voters internalize general equilibrium effects at the central but not at the local level. This renders the degree of tax...

I offer a macroeconomic perspective on the "Reserves for All" (RFA) proposal to let the general public use electronic central bank money. After distinguishing RFA from cryptocurrencies and relating the proposal to discussions about narrow banking and the abolition of cash I propose an...

Standard models of tax evasion implicitly assume that evasion is either fully detected, or not detected at all. Empirically, this is not the case, casting into doubt the traditional rationales for interior evasion choices. I propose two alternative, dynamic explanations for interior tax evasion...

A balanced budget requirement does not only prevent fiscal policy makers from smoothing tax distortions but also affects their preferred choice of government spending. The paper analyzes the conditions under which groups opposed to government spending might want to implement a balanced budget...

We analyze economic rationales for, and possible alternatives to, the Stability and Growth Pact (SGP). We identify various cross-country spillover effects and domestic policy failures as potential rationales. The two sets of problems suggest different corrective measures, and different measures...

We analyze the effect of changes in fertility and longevity on taxes, the composition of government spending, and productivity. To that purpose, we introduce politics in an OLG economy with endogenous growth due to human and physical capital accumulation. Population ageing shifts political power...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

I analyze how lack of commitment affects the maturity structure of sovereign debt. Governments balance benefits of default induced redistribution and costs due to income losses in the wake of a default. Their choice of short- versus long- term debt affects default and rollover decisions by...
