This paper analyses the effects of disease and war on the accumulation of human and physical capital. We employ an overlapping-generations frame-work in which young adults, confronted with such hazards and motivated by old-age provision and altruism, make decisions about investments in schooling...

This paper surveys intergenerational altruism in neoclassical growth models. It first examines Barro's approach to intergenerational altruism, whereby successive generations are linked by recursive altruistic preferences. Individuals have an altruistic concern only for their children, who in...

In an overlapping generations economy, lenders fund risky investment projects of firms by drawing up loan contracts in the presence of an informational asymmetry. An optimal contract entails the issue of only debt, only equity, or a mix of the two. The equilibrium choice of contract depends on...

In this paper we study the implications of population ageing in an economy with a sizeable non-traded goods sector. To this effect a highly stylized micro-founded macro model is constructed in which the age structure of the population plays a non-trivial role. The model distinguishes separate...

One of the key decisions that economists working on integrated studies of climate change face is the selection of the method of accounting for damages resulting from possible climate change across a long temporal scale and the method for the intertemporal comparison of the costs associated with...

In this paper we have analyzed existence, uniqueness and stability of a steady-state equilibrium in an overlapping generations model with monopolistic competition and free entry and exit of firms. We establish a strenghtened Inada condition that is sufficient to exclude global contraction for...

The issue addressed in this paper is how robust dynamically efficient steady state equilibria in a 55 period overlapping generations economy are to changes in the parametrization of the model. Numerical simulations are used to detect parameter constellations which lead to non Pareto optimal...

Rejuveniles are people who cultivate tastes and mind-sets traditionally associated with those younger than themselves. (Noxon, 2006) In this paper, we study a standard AK growth model of overlapping generations populated by rejuveniles. For our purposes, rejuveniles are old agents who derive...

This paper extends Gertler's (1999) tractable overlapping generations model with life-cycle features by allowing for distortionary taxation, demographic transition and stochastic variation in demographic structure. The model is then used to study demographic change in the small open economy of...

It is shown that although government debt in principle has an ambiguous effect on the steady state capital stock in an OLG model of the Blanchard-Cass-Yaari variety, once stability of the steady state equilibrium is imposed there is an unambiguous negative relation between the level of...
