Assessments of whose income growth is the greatest and whose is the smallest are typically based on comparisons of income changes for income groups (e.g. rich versus poor) or income values (e.g. quantiles). However, income group and quantile composition changes over time because of income...

We propose a characterisation of an aggregate measure of growth that takes into account the initial economic conditions of individuals. Our measure is a weighted average of individual income growth with weights that are decreasing with the rank of the individual in the initial income...

Gender-based discrimination is a pervasive and costly phenomenon. To a greater or lesser extent, all economies present a gender wage gap, associated with lower female labour force participation rates and higher fertility. This paper presents a growth model where saving, fertility and labour...

This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction.

Relatively little is known about the impact of welfare reform on children's living arrangements, which was an important focus of reformers. We use data from the March CPS to examine this question. Our findings suggest three main conclusions. First, welfare reform in some cases has had large...

This paper examines the association between use of infertility treatment and infant and child health outcomes. Infertility treatment makes conception possible for many couples who otherwise would have been unable to reproduce. Many treatments also increase the chance of having a multiple birth,...

This paper addresses the issue of optimum population with two concerns : avoiding both the absolute repugnant solution that amounts to giving to an infinite number an infinitesimal amount and the marginal repugnant solution in which equilibrium consumption decresases with income. To avoid these...

This paper argues that earlier quantitative research on the relationship between heterosexual partners' earnings and time spent on housework has two basic flaws: First, it has focused on the effects of women's shares of couples' total earnings on housework, not considering the simpler...
