Joachim De Weerdt is a development economist based in Belgium. He is Senior Lecturer at the University of Antwerp, Senior Research Fellow at LICOS (KU Leuven) and Non-Executive Director at EDI.
Joachim uses economics to improve our understanding of the lives of the poor in low-income countries. He draws inspiration from work outside of economics and strives to disseminate his findings across mutliple academic disciplines. He has two decades of field experience in Africa and of engagement with policy makers and practicioners who fight poverty. Most of his research is based on data he has collected himself. In recent years his research focus has been on urbanisation, informal insurance, social networks, early childhood development and measurement through surveys.
Joachim has lived and worked as an entrepreneur and as a researcher in Africa for 12 years. In 2002 he co-founded Economic Development Initiatives (EDI), a research institution based in Tanzania, where he served as Research Director till 2014. During that time the company grew from a small two-person start-up to one of Africa’s most respected research houses with 40 core employees and frequently up to 100 additional project-based staff. As a spin-off from this work EDI designed a new-generation software package, called surveybe, which is being used worldwide to conduct surveys on handheld devices. By 2014, after 12 years of hard and exciting work building a private sector firm in Africa, the baby had grown into an independent and thriving adult, allowing Joachim to step down as its Research Director and devote himself more fully to academia. Since then, EDI has not only consolidated its position as the go-to data collection firm in Tanzania, but has also expanded into neigbouring Uganda and Mozambique.
Joachim has dozens of scientific articles to his name and has published in top journals from different disciplines, such as Review of Economics and Statistics, Journal of Human Resources, Journal of Development Economics, World Development, Demography, AIDS and the International Journal of Epidemiology. A full list is given below.
