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...

Beyond natural sterility, there are two main types of childlessness: one driven by poverty and another by the high opportunity cost to child-rearing. We argue that taking childlessness and its causes into account matters for assessing the impact of development policies on fertility. We measure...

Through indirect inference, we investigate the extent to which religions’supposed pronatalism is detrimental to growth via the fertility/education channel. Using censuses from South-East Asia, we first estimate an empirical model of fertility and show that having a religious affiliation...

Even in countries where there is a male-biased sex ratio, it is still possible for the marriage market to be balanced if men marry younger women and population is growing. We define a missing Brides Index to reflect the intensity of the possible imbalance at steady state, taking into account the...

Consider an economy populated by males and females, both rich and poor. The society has to choose one of the following marriage institutions: polygyny, strict monogamy, and serial monogamy (divorce and remarriage). After having identified the conditions under which each of these equilibria...
