This paper proposes an AK-model with endogenous time preferences and borrowing constraints. It is assumed that the subjective discount factor of a household is an increasing function of its relative income. First we describe the structure of balanced-growth equilibrium paths, on which the...

We analyze the impact of globalization upon education and inequality in advanced countries (the North) and upon the world welfare. We build a simple two-goods North-South intergenerational model with human capital formation and in which globalization consists of an increase in the size of the...

We develop two models of economic growth with exhaustible natural resources, exogenous technical progress and consumers heterogeneous in time preferences. The first model assumes private ownership of natural resources. In the second model, natural resources are public property and the resource...

This paper considers a one-sector economic growth model with several infinitely-lived heterogeneous households, who differ both in the discount factors as well as preferences over consumption. Unlike the extreme form of borrowing constraint observed in the classical Ramsey model, recently...

We model a successive-generation economy in which parents, motivated by fam- ily altruism, decide to nance or not their o spring's capital accumulation on the basis of their altruistic motive, their own income and the equilibrium ratio between skilled-labor and unskilled-labor wages. The...

We model a successive-generation economy in which parents, motivated by family altruism, decide to finance or not their offspring's human capital accumulation on the basis of their altruistic motive, their own income and the equilibrium ratio between skilled labor and unskilled labor wages. The...

We assume a population of in nitely-lived households of the economy split into two groups : one with a high discount factor (the patient) and one with a low one (the impatient). The environmental quality is deteriorated by rm's polluting emissions. The governmen tal policy consists in proposing...

We study a parametric politico-economic model of economic growth with productive public goods and public consumption goods. The provision of public goods is funded by a proportional tax on consumers' income. Agents are heterogeneous in their initial capital endowments, discount factors and the...

We investigate the convergence property of the capital stock sequence in Ramsey equilibria with limited borrowing by the households. In our model, at the beginning of each period, households are allowed to borrow against their end of the period wage income. Under this assumption the capital...
