Pre-print, Working paper: Recent years have seen a surge in economic integration agreements (EIAs) and the development of non-tariff measures (NTMs). As a consequence, a growing number of EIAs include provisions on NTMs. This paper focuses on provisions on technical regulations. We investigate whether the technical requirements contained in North-South Agreements affect international trade. More particularly, using a gravity equation, we assess to what extent North-South harmonization of technical barriers creates or reinforces a hub-and-spoke trade structure potentially detrimental to the integration of Southern countries in world economy.
