This paper studies the conditions under which an IT revolution may endogenously occur. To this end, we construct an endogenous growth multisectoral model with a preeminent IT sector. Technological progress is embodied : New softwares can only be run on the most recent generations and hardware....

We compare the dynamics under myopic foresight and under perfect foresight in an overlapping generations model with capital accumulation and two-period lived individuals. When the rational dynamics are defined and the myopic dynamics are monotonic, the study of myopic foresight allows to...

We argue the inequality and growth are linked through differential fertility and the accumulation of human capital. We build an overlapping-generations model in which dynasties differ in their initial endowment with human capital. Growth, the income distribution, and fertility are endogenous....

The idea that sector-specific unions has mainly been used to support the empirical observation that wages are highly correlated among industries. The sources of wage interdependence can mainly be found in unions‚ preferences, in the nature of technology and in price and demand determination....

Past experiences and social forces have been incorporated into tastes in order to analyze various microeconomic issues. We use these extended preferences to model the making of standard-of-living aspirations and study their effect on macroeconomic variables. We concentrate first on consumption...

To cope with the observed drop in fertility, four policy options are generally considered : lowering pension benefits, increasing social security contributions, postponing retirement, and reducing public debt in advance. To assess the respective merits of these options, we analyze the optimal...

We address the issue of optimal growth when standard-of-living aspirations are transmitted from one generation to the next. We derive the condition for the optimal solution to be stable in the saddle-point sense and show that this optimal solution may display damped oscillations even when the...

We study how economic growth is affected by demographics in an overlapping generations model with a realistic survival law. Individuals optimally chose the dates at which they leave school to enter the labor market and at which they retire. Endogenous growth arises thanks to the accumulation of...

This paper evaluates the relevance of q theories under stochastic demand and capacity constraints by estimating an investment function for the Belgian economy. Under these theoretical conditions, we find that the investment rate depends on average q and on the expectations about the degree of...
