In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. We characterize sub-game perfect Markov equilibria where immigration policy and pay-as-you-go (PAYG) social security...

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...

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...

Rejuveniles are "grown-ups who cultivate juvenile tastes in products and entertainment". In this note, we study a standard AK growth model of overlapping generations populated by rejuveniles. For our purposes, rejuveniles are old agents who derive utility from "keeping up" their consumption with...

This paper presents a two-country migration model, following Galor (1986), in which the world population consists of two types individuals. Individuals with a high (low) degree of altruism give to their children a high (low) level of bequest. Production uses three inputs: immobile land, mobile...

This paper investigates the effect of altruism on the pattern of labour migration in a two-country overlapping generations model. We show that differences in degrees of altruism across countries lead to bilateral migration flows. Starting from the autarkic steady-state equilibrium, restrictions...

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...

This paper examines the existence condition of a balanced growth path in an overlapping generations model in which production uses three inputs, physical capital, human capital and land, with increasing returns to scale. Human capital is the engine of economic growth. It is shown that, unlike...
