How the Reduction of Regulatory Barriers to Trade in Services may Affect the Architecture of Global Value Chains: the Case of TISA

This paper investigates the likely impacts of TISA negotiations on the Architecture of Global Value Chains, using a rather innovative approach on the marriage between General equilibrium models and input-output models. Ad valorem equivalents of regulatory barriers to trade in services will be estimated for all TISA members using state of the art gravity equations and Poisson regressions. General equilibrium effects stemming from a static model will be evaluated according to the trade in value added logic, instead of the traditional gross trade analysis, shedding some light on how services negotiations may impact global/regional value chains for both TISA members and outsiders.
