|Does ageing impoverish developed economies?
Topic: In this short article in the journal Pour l'éco (in French), I
explain why ageing should not be seen a threat for our societies. I
recall how the Ben-porath effect has contributed to the growth of our
economies and how immigration may help solving issues related to thedistortions of age pyramids due to ageing.
The engine of technology: growth, development and family.
this debate (in French) with David Stadelmann from University of
Bayreuth, we expose our views on the past, the present and the future
of economic growth. I explain why I believe in humankind's capacity to
address the climate challenge but also why I am convinced that this can
be done only if governments invest massively in research.

Childlessness is high in the US once again, but this time it’s driven by choice, not poverty:
Abstract: Recent years have seen a rise in childlessness rates in the US close to
levels not seen for more than a century. In new research which examines
the drivers of childlessness then and now, Thomas Baudin, David de la
Croix and Paula E. Gobbi find that while in the early 20th century
poverty meant that many women were forced into having fewer children,
better education and higher income for women are now the causes of
Fécondité et Infécondité aux Etats-Unis : entre choix, fatalité et inégalités
En 1960, Gary Becker publiait « An economic analysis of fertility » et
en 1981, la première édition du « Treatrise on the Family », ouvrages
qui n’ont pas tout à fait fini d’agiter le monde des économistes (de
certains en tout cas) et des démographes. Dans ces contributions, ainsi
que dans nombre de ses articles, Becker défend l’idée que de grandes
décisions telles que se marier, devenir parent ou divorcer résultent
d’un arbitrage rationnel. Cet arbitrage est régi par la même mécanique
que celle qui meut un individu dans un supermarché: il ou elle maximise
son utilité sous contrainte ; contrainte de budget mais pourquoi pas
aussi de participation.
Endogenous childlessness and stages of development
The fertility of women in developing countries is higher on average
than in developed countries, yet many women in developing countries
remain childless. This column argues that understanding the causes of
why some women choose childlessness is important if we wish to predict
the impact that development policies have on the demographic transition
of poor countries.
