3. 14.02.2014 2 World Trade Institute Berne Sub-text What is the (services) trade effect of a PTA delineated by type (goods v services) and form (North-North v North-South, symmetric v asymmetric)?What is the (services) trade effect of a PTA delineated by type (goods v services) and form (North-North v North-South, symmetric v asymmetric)? Is there an incremental trade effect from a services accord if a goods only agreement is already in place?Is there an incremental trade effect from a services accord if a goods only agreement is already in place?

4. 14.02.2014 3 World Trade Institute Berne Why might we expect a positive trade effect? Barriers to services trade are often prohibitive and not revenue generating, so fewer costs of trade diversionBarriers to services trade are often prohibitive and not revenue generating, so fewer costs of trade diversion A la trade in goods, benefits from possibilities for increased competition, exploitation of economies of scale and inducement of knowledge spilloversA la trade in goods, benefits from possibilities for increased competition, exploitation of economies of scale and inducement of knowledge spillovers However, the sequence of liberalization matters more in services trade than in the case of goods trade because location-specific sunk costs of production are important, so even temporary privileged access for an inferior supplier can translate into a long-term market advantage (Mattoo & Fink, pp 3)However, the sequence of liberalization matters more in services trade than in the case of goods trade because location-specific sunk costs of production are important, so even temporary privileged access for an inferior supplier can translate into a long-term market advantage (Mattoo & Fink, pp 3)
