Joachim De Weerdt is a development economist based in Belgium. He is Associate Professor at the University of Antwerp and Senior Research Fellow at LICOS (KU Leuven).
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 multiple academic disciplines. He has two decades of field experience in Africa and of engagement with policy makers and practitioners 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 in Africa, informal insurance through social networks, long-run effects of early childhood circumstances and measurement through surveys.
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.
Joachim 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 over 100 project-based field staff. Field operations later expanded across East Africa, while survey design and training services were provided across the globe.
In 2018 EDI was acquired by Mathematica, a US-based policy research company with over 1,200 employees. The new investor strengthened EDI with its extensive expertise, vast professional networks and financial clout. Today EDI continues on its growth path, operating independently as a wholly owned subsidiary of Mathematica.

Monitoring Emerging Small Towns in Tanzania: a proof of concept study (London School of Economics through the International Growth Centre). Providing technical support to Tanzania’s Prime Office Regional Administration and Local Government (PO-RALG) to collect data and compile statistics on Emerging Small Towns (ESTs). PO-RALG estimates indicate that there may be as many as 800 ESTs, many of which are undocumented within the government system. PO-RALG has identified the lack of accurate and timely information on ESTs as a major obstacle to sound policy making and urban planning. This project is joint with Neil Chalmers (independent consultant) and Hanne Van Cappellen (University of Antwerp).
