We analyze the short and long run effects of demographic ageing---increased longevity and reduced fertility---on per-capita growth. The OLG model captures direct effects, working through adjustments in the savings rate, labor supply, and capital deepening, and indirect effects, working through...

We consider intergenerational transfer policies that are equivalent in terms of the allocation they support, in particular pay-as-you-go financed policies on one hand and policies with explicit government debt on the other. We analyze the conditions under which political decision makers are...

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...

The recent sovereign debt crisis has rekindled the debate on the role of austerity. By austerity, we mean consumption levels below those desired and supported by a country's repayment capacity. We shed light on the function, properties, and optimal size of austerity by developing a model that...

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...

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...

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...

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 develop a model with official and private creditors where the probability of sovereign default depends on both the level and the composition of debt. Higher exposure to official lenders improves incentives to repay but also carries extra costs such as reduced ex post flexibility. We...
