This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall 'life-cycle' risk aversion. We provide a...

In earlier work we documented two episodes in which a sharp fiscal consolidation was associated with a surprisingly large expansion in private domestic demand. In this paper we draw on further evidence to investigate if and when fiscal policy changes can have such non-Keynesian effects. In the...

This paper shows that multiple growth paths may occur in a politico-economic model of endogenous growth. This multiplicity is characterized by the coexistence of a low-tax, low-capital-flight equilibrium and a high-tax, high-capital-flight equilibrium. The likelihood of multiplicity is crucially...

We investigate intergenerational risk sharing in two-pillar pension systems with a pay-as-you-go pillar and a funded pillar. We consider shocks in productivity, depreciation of capital and inflation. The funded pension pillar can be either defined contribution or defined benefit, with benefits...

It is well known that over the next few decades there will be significant changes in the demographic structures of nearly all developed countries; in the absence of massive immigration, or of catastrophic new fatal illnesses, by the middle of the next century the ratio of people of working age...

In this paper we construct a stochastic overlapping-generations general equilibrium model in which households are subject to aggregate shocks that affect both wages and asset prices. We use a calibrated version of the model to quantify how the welfare costs of severe recessions are distributed...

In this paper we perform simulations with a stylized model of Germany and the United Kingdom to show which generations might be direct gainers, and which losers, from a transition to funded state pensions. We estimate what the structure of inter-generational bequests would need to be in a...

In an overlapping generations model, rents to human capital play a key role in increasing savings. In the absence of such rents, the return to human capital is entirely appropriated by the old and accumulation is entirely determined by the income to fixed factors. If rents are introduced by...

We analyse the impact of micro-founded political institutions on environmental policy and economic growth. We model an overlapping-generations economy, where individuals differ in preferences over the environment (as well as in age). Labour taxation and capital taxation is used to finance a...

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...
