David de la Croix (French: [david də la kʁwa]; born 22 April 1964) is a Belgian scientist and author in the field of economic growth and demographic economics. He is professor at the Université catholique de Louvain.

Contributions

David de la Croix and his co-authors Raouf Boucekkine and Omar Licandro developed a unified framework encompassing longevity, education and economic growth.[1] The basic link is that a longer life expectancy justifies a greater investment in education (this is called the Ben Porath mechanism in the related literature), which in turn fosters economic growth by promoting human capital accumulation. The resulting model has been taken to several sets of demographic data pertaining to the 17th and 18th centuries, providing evidence on the role of demographics in the Industrial Revolution. This conclusion is reinforced by the work with Omar Licandro on famous people, which provides a broad picture of the evolution of the longevity of the elite over the last centuries, using a database of hundreds of thousands of famous people (nobles, artists, scientists etc.).[2]

In a similar vein, de la Croix and his co-author Matthias Doepke contributed to the development of a unified framework encompassing fertility, education, inequality and growth. Here, the link involves economic inequality: wealth and education entail lower fertility and more spending on education, thereby deepening inequality; but an increase in inequality lowers average education, hence growth; taking the model to data reveals that differential fertility accounts for most of the empirical relationship between inequality and growth: it implies that neglecting fertility behavior in analyzing the growth-inequality nexus can be strongly misleading.[3]

The kind of work mentioned here has implications for policy decisions, definitely with respect to development,[4] but also with respect to education, pensions or migration in developed countries. Some of these implications have been formulated in policy briefs accessible to the general public and politicians.[5][6]

Further work by de la Croix includes a study of childlessness, where, together with Thomas Baudin and Paula Gobbi, he lists a series of causes of childlessness (natural, social, voluntary) and proposes a methodology to identify their respective importance based on a structural model.[7] Policy implications of this theory are non negligible, in particular when considering that avoidable involuntary childlessness reduces the capability set of poor people.[8] With Fabio Mariani, de la Croix is interested in understanding the economic determinants of changes in marriage laws in the very long run.[9] Changes in income level and in its distribution are key to understand the switch from polygyny to strict monogamy that happened during the Urban Revolution in Europe. Later on, from the 19th century onward, he rise of income per person triggered the vote of "Serial monogamy" laws, allowing for divorce an remarriage. A generalization of this theory for the rest of the world is still needed.[10]

Other scientific activities

De la Croix is the instigator and editor-in-chief of the Journal of Demographic Economics (JODE). The objective of JODE is to promote research in the field of study that lies at the intersection of economics and demography. An analysis of demographic change may benefit from an understanding of economic incentives, which are in turn influenced by demographic changes and trends.

Books published

In 2002, he published with Philippe Michel a treatise on overlapping generations models as a tool to study economic growth, dynamics and policy.[11]

In 2012, his book on fertility, education, growth and sustainability[12] studies the consequences for macroeconomic outcomes, such as income inequality and growth, of individual fertility choices.
