“…The way labour has an impact on trade is not only because, perhaps obviously, services and products come to life as a result of some kind of human activity, which inevitably becomes a factor of production in the trade of these goods and services; but particularly because such activity takes place within a legal system setting parameters to it; this will have a bearing upon the costs of labour, in turn affecting the competitive advantage of the country providing those goods and services. 74 Differences in labour standards have been found to explain differences in international trade patterns, fostering concerns about 'races-tothe-bottom.' 75 The intrinsic economic relevance of labour to trade has traditionally justified the inclusion of international labour standards in trade agreements: since the 1970s, developed countries voiced concerns about cheaper labour in developing countries, and called for provisions on core labour standards to be included in the framework of the WTO.…”
