On the sides of the MENASP 2019 Conference, we had the pleasure to talk to Researcher Walid Merouani about his work and research interests, about his experience in general of the conference, and specifically what was the most interesting part of it. Merouani holds a PhD in Economics from the University of Caen-Normandy & a PhD in Economics and Applied Statistics from the High School of Statistics and Applied Economics (Algiers). Since 2011, he has investigated issues of pension, social protection and behavioural economics. He has published articles and has been involved in research projects related to these issues.
