Last Friday, we organized the Fifth ERMEES workshop with Amélie Barbier-Gauchard and Pierre Lesuisse, together will all the ERMEES team. It was very pleasant to see old friends and meet very nice people. The scientific discussions were excellent and the atmosphere very friendly according to the participants. The keynotes of Klaus Prettner, Vienna University of Economics and Business, Austria, and Jakob de Haan, University of Groningen, the Netherlands were fascinating.
