Most former participants have chosen a career in academia. Indeed, the majority of the participants who have completed their PhD or their post doc are now academics (55%), namely they obtained a position as full, associate or assistant professor in various universities, or they work as a researcher in a research institute (such as CNRS and INRA in France, or CNR in Italy etc.).
Another significant number of former students are currently working as economists in international institutions, national banks, regulatory agencies, development agencies and international research centers. As an non-exhaustive list, we can highlight the following institutions where IOEA alumni currently hold positions: Brazilian Regulatory Agency, Central Bank of Malaysia, Deutsche Bank, European Banking Authority, European Central Bank, European Commission, European Court of Justice, European Investment Bank, European Medicines Agency, European Regional Development Fund, French Agency for Development, French Authority of Competition, French Institute of Research for Development, French Regulatory Authority for Railway, International Health Economic Association, International Labor Organization, National Bank of Poland, National Bank of Slovakia, Organization for Economic Cooperation and Development, United Nations, World Bank.
If the majority of former students now work in universities, or in governmental agencies, or in international institutions, it is important to note that some of them also went to the private sector (11,8%). Many of them currently work for international firms, banks or consulting groups. Once again, we can quote the following non-exhaustive list of organizations: Capgemini, Crédit Suisse, Ernst and Young, McKinsey and even Facebook.

The former candidates who became academics are now mainly working in European universities. They can be found for example in the University Pompeu Fabra (Spain), the Manchester Metropolitan University (UK), the University of Sienna (Italy), Humboldt (Germany), the Copenhagen Business School (Denmark), the University College London (UK), the University of Lausanne (Switzerland), several Parisian universities (Sorbonne, Pantheon Assas, etc.) etc.  There are also alumni spread throughout the world in the US and beyond as at the University of Las Americas Puebla (Mexico), HEC Montréal (Canada), the University of Melbourne (Australia), etc.

These former participants, who chose to pursue a career in academia, make up a network of researchers working on various themes of institutional and organizational economics and continue to contribute actively to those research areas. The international dimension of former participants, made possible by IOEA/ESNIE, is doubtless highly important for progress in research. In terms of scientific output, former participants published in internationally prestigious journals, such as the Journal of Law Economics and Organization, Games and Economic Behaviour, Journal of Public Economics, Journal of Public Economic Theory, Journal of Development Economics, Journal of Institutional and Theoretical Economics, Journal of Economic Surveys, European Journal of Law and Economics, Strategic Management Journal, Theory and Decision, Journal of Public Administration and Research Theory, Recherches Economiques de Louvain, Review of Industrial Organization, Utilities Policy, Energy Policy, Ecological Economics, Annals of Public and Cooperative Economics Public Choice, etc. The multidisciplinary dimension of former participants can also be seen through their publications in journals focusing on other scientific disciplines whose subject matter can be fruitfully analyzed from the perspective of institutional and organizational economics. Among such journals, we will cite the following; International Journal of Human Resource Management, International Journal of Law and Information Technology, Journal of Management and Finance, Organizational Studies Journal, Journal on Chain and Network Science, International Journal of Education Research, Management Accounting Journal, Research in Economic Anthropology etc. Furthermore, former participants have also contributed to books and edited volumes (such as the Handbook of Economic Inequality).

As an additional illustration of the attractiveness of IOAE, students frequently apply several times while the policy of the academy is to avoid recurrent participation in order to promote diversity and renewal. Let us also note that, 18 former students came back to the academy as workshop organizers. Those people are, in alphabetical order, Veneta Andonova, Gonzalo Caballero, Tommasco Ciarli, Mikhail Drugov, Ruben Enikolopov, Marco Faravelli, Roberto Galbiati, Paul Jensen, Mark Koyama, Antoine Loeper, Anne Neumann, Claude Parthenay, Yannick Perez, Matteo Rizzolli, Maria Alessandra Rossi, Petros Sekeris, Michael Vlassopoulos and Giorgio Zanarone.
