In this paper we attempt to describe the general reasons behind the world population explosion in the 20th century. The size of the population at the end of the century in question, deemed excessive by some, was a consequence of a dramatic improvement in life expectancies, attributable, in turn,...

In this paper, we characterize the relationship between the initial distribution of human capital and physical inheritances among individuals and the long-run distribution of these two variables. In a model with indivisible investment in education, we analyze how the initial distribution of...

I document extremely son-biased sex ratios at birth among Asian-born parents in Spain. Using data on the universe of registered births in Spain during 2007- 2012, I show that there are 117 boys per 100 girls born to Indian parents, compared with a national average of 107 boys per 100 girls. The...

We take advantage of a natural experiment to provide new, credible evidence on the health consequences of scheduling births early for non-medical reasons. In May 2010, the Spanish government announced that a 2,500-euro universal “baby bonus” would stop being paid to babies born after...

In this paper we analyse the reasons behind the evolution of the gender gap and wage inequality in South and East Asian and Latin American countries. Health human capital improvements, the exposure to free market openness and equal treatment enforcement laws seem to be the main exogenous...

The aim of this paper is to understand recent observations of fertility, female employment, and participation rates in O.E.C.D. countries. These observations indicate that fertility rates are positively correlated with female employment ratios and participation rates across O.E.C.D. countries...

Aid for fighting infectious and parasitic diseases has had a statistically significant role in the under-five mortality reduction in the last decade. Point estimates indicate a country average reduction of 1.4 deaths per thousand under fives live-born attributable to aid at its average level in...
