De l'Ancienne Economie Institutionnelle à la Nouvelle Economie Institutionnelle: une introduction à quelques débats

The aim of this paper is to briefly review the main debates between the New Institutional Economics (NIE) and the Old Institutional Economics (OIE). While the NIE is considered in the literature as essentially orthodox, the OIE’s thesis are mainly heterodox. From a theoretical perspective, (i) the nature of institutions, (ii) the organization of firms and (iii) the link between institutional change and economic development are central in the debate. From an empirical perspective, the measures of institutional quality and the methods used to capture institutional changes and their impact on development are the key points of divergence between NEI and OIE. However, some authors are quite optimistic about a potential convergence of the two school of thoughts, which could potentially offers new perspectives on the understanding of institutional phenomenons in economics
