Book excerpt: He finds that, in spite of US comparative advantage in service activities, service firms' export participation lags manufacturing firms. Jensen evaluates the impediments to services trade and finds evidence that there is considerable room for liberalization-especially among the large, fast-growing developing economies. The policy recommendations coming out of this path-breaking study are quite clear. The United States should not fear trade in services. It should be pushing aggressively for services trade liberalization. Because other advanced economies have similar comparative advantage in service, the United States should make common cause with the European Union and other advanced economies to encourage the large, fast-growing developing economies to liberalize their service sectors through multilateral negotiations in the General Agreement on Trade in Services and the Government Procurement Agreement.
