Established in 1933, the Francqui Chairs aim to promote exchanges between universities and highlight academic excellence. Each year, Belgian universities invite professors from other institutions to deliver a series of approximately ten hours of lectures, preceded by an inaugural lecture open to a wider audience. 

This year, KU Leuven has chosen to invite Catherine Guirkinger, a professor of economics at the University of Namur. “What interests me is how arrangements within couples and families are reshaped when the world around them changes, and how these changes affect each of their members.” “Her research, conducted primarily in sub-Saharan Africa but also in Europe, combines field surveys, experiments, and historical data.” 

The Francqui Chair will begin with an inaugural lecture titled “Economic Change and the Family: Adjustment and Resistance,” followed by three more technical courses designed for master’s and doctoral students. Catherine Guirkinger will demonstrate how economic changes, laws, or social norms can influence decisions made within households. “We cannot ignore what happens within the family: all policy is, in a way, filtered through it,” she emphasizes. 

She will draw in particular on her research on divorce, domestic violence, decision-making within couples, and the influence of the economic environment on families. These courses will also provide an opportunity to engage with students already involved in research. “You can go deeper with an audience like this,” Catherine Guirkinger notes. “It’s always very stimulating.”  

This Francqui Chair also builds on an existing relationship between UNamur and KU Leuven. Economists from both universities have collaborated, in particular, on an EOS (Excellence of Science) project, the joint research program of the FNRS and the FWO. Catherine Guirkinger has very fond memories of that experience: “This program led to very fruitful scientific exchanges. This chair is a wonderful opportunity to build on them.” 

Her presence in Leuven will thus provide a new opportunity to exchange ideas, share research conducted in Namur, and further the collaboration between the two institutions. Congratulations to Catherine Guirkinger on this prestigious honor! 

A phenomenon that has received little attention in the scientific literature has caught the attention of Catherine Guirkinger, an economist and professor at Sciences Po’s Faculty of Economics, Management, and Communication (EMCP), and her colleagues, Pablo Alvarez-Aragon, a postdoctoral researcher at the University of Bologna, and Jean-Philippe Platteau, professor emeritus at UNamur: the conversion of African women to “new Christian churches.” This term encompasses new Christian-inspired religious movements such as evangelical or Pentecostal churches, which are growing rapidly on the African continent and in other regions of the world. 

“Statistical analyses show that women are much more likely to be members of these new churches than men. This imbalance is unique to these new churches and is not observed in Catholic churches or other traditional religions,” explains Catherine Guirkinger. 

To explain this trend of female conversion, Catherine Guirkinger puts forward a hypothesis centered on the support services offered by these churches, which encourage women in their economic empowerment. “In a previous research study conducted in Benin, we observed that when women gain access to new sources of income, they are more likely to convert,” explains Catherine Guirkinger. “When interviewed, they frequently mention these support services, which help them overcome the obstacles they face in accessing new economic opportunities. These services are not solely financial in nature but also include ‘spiritual protection,’ in a context where ‘successful’ women are often accused of or fall victim to witchcraft.” 

Thus, initial analyses suggest that religious conversion is correlated with the economic cycle: it is more frequent when incomes rise. “This is a rather unexpected finding,” the researcher notes. “Religious conversion is generally interpreted as a response to difficulties, particularly financial ones. Yet it would seem that economic growth, on the contrary, encourages membership in these new churches.” 

One of the gray areas Catherine Guirkinger hopes to shed light on is identifying the roles these churches play in the empowerment of these women in the face of rather conservative and patriarchal gender norms. To understand this, Catherine Guirkinger will employ a combination of methods: statistical data, qualitative surveys, econometric analyses, as well as “economic games”—role-playing exercises designed to understand individual behaviors through simulated scenarios.  

The project will run for four years, from 2026 to 2030. The project team includes a doctoral student (currently being recruited), Jean-Philippe Platteau, professor emeritus at the Defipp Institute, and Pablo Alvarez of the University of Bologna (Italy). 

Catherine Guirkinger specializes in development economics. At the Center for Economic Development Research (CRED) of the DeFIPP Institute (Development Finance & Public Policies), she conducts research on changes in family structures during development processes. Her work also focuses on the respective roles of women and men in society and on the role of public institutions in the broader sense. Catherine Guirkinger explores these issues particularly in the colonial context, drawing on archival data and historical surveys. In 2017, she received European ERC funding for this research program, and in 2024, she secured funding from the F.R.S-FNRS for a collaborative project with Bruno Schoumaker, professor of demography at UCLouvain, aimed at digitizing census data. As a professor, Catherine Guirkinger teaches courses in microeconomics and development economics. 

Benoit Decerf, holder of a PhD in cotutelle between UCLouvain and the University of Bielefeld (Germany), joined the University of Namur in 2016. His career path led him to significant experience as a researcher, notably from 2020 to 2025, when he was seconded to the World Bank's research center in Washington DC. In this context, he contributed to the development of tools designed to measure poverty and well-being. The aim? To better understand development inequalities between countries and better assess development policies.

"Indeed, it seems difficult to quantify a person's state of health in euros. To address the limitations of monetary indicators, alternatives such as the Human Development Index or multidimensional poverty measures have been proposed to include aspects such as life expectancy and access to education," he continues. At the Development Economics Research Center, Benoit Decerf's work is part of these efforts to improve development indicators.

His stint at the World Bank allowed him to take part in improving the indicators used by this institution. "In addition to measuring extreme poverty, defined by the threshold of $2.15 per day per person, which the United Nations would like to see fall below 3% of the world's population by 2030, the World Bank also measures "shared prosperity". This concept is intended to be more inclusive than poverty, by taking into account the incomes of everyone, not just the poor, but maintaining the importance of inequalities by weighting the incomes of the least well-off more heavily", explains the economics researcher. With his co-authors, Benoit Decerf has therefore proposed a new indicator, the Prosperity Gap, which aims to be both simple to explain and mindful of inequalities.

This example illustrates the pragmatic approach followed in his research. Rather than looking for the ideal indicator, Benoit Decerf seeks to build on existing indicators, identifying their main limitations, and seeking to improve them while taking into account the constraints faced by practitioners.

Guilhem Cassan - Department of Economics, EMCP Faculty and Institut DeFiPP (CRED) at the University of Namur - and Julia Cagé - Department of Economics, Sciences Po Paris -, are studying in particular how political life influences the newspaper market in the USA and India, using newly collected data and cutting-edge econometric methods.

This link through research feeds back into the teaching of the economics department, which has a long tradition of integrating cutting-edge research and teaching. Professor Julia Cagé has been a guest lecturer on several occasions in the EMCP Faculty courses, in this case in the Block 2 Integrated Teaching Unit and in research seminars organized by the Institut DeFiPP.

The Yrjö Jahnsson Prize is awarded every two years to a European economist under the age of 45 "who has made a contribution in theoretical and applied research of outstanding importance to the study of economics in Europe". The 2025 prize is awarded jointly to Julia Cagé and David Yanagizawa-Drott for their work on the political economy of the media. Julia Cagé's most recent book, "Une histoire du conflit politique", co-authored with Thomas Piketty, had an extraordinary media and political impact in France in 2023.
