The study tries first to assess the extent of similarities and divergences among services rules in regional trade agreements as compared to the GATS. To do so, it uses a typology identifying variations in 48 key provisions structured under seven themes commonly found in RTAs and using the GATS as a benchmark. The analysis identifies two main families of agreements (GATS-inspired and NAFTA-inspired) and a residual category. The paper briefly explores the historical development that led to these families as well as their geographical spread both on an agreement by agreement basis and a country by country basis. The paper then analyses by theme the variations found in the RTAs among services rules including their novelty as compared to the GATS. Given the lack of available information on the implementation of the agreements the paper tries to assess whenever possible the magnitude of the discrepancies and their practical impacts. While subject to some qualifications, the results of the study are relatively straight forward: there is no spaghetti bowl in services rules, but just two families and one residual category. The details reveal that the degree of divergence between those two families does not overall seem insurmountable. This assessment concords with other studies (e.g. Marchetti, Roy) that have equated them in terms of national treatment and market access and have compared directly commitments undertaken under the three families of agreements. One may even note a certain tendency to a convergence towards the GATS model (e.g. the addition of market access clause in the second generation of NAFTA-like agreements or the use of GATS-type architecture by EU for agreements else than pre-adhesion ones).
