5 Import content of exports – trade in value added Three ways of measuring the fragmentation of the value chain 1 Using firm surveys 2 Foreign trade statistics The increase in the share of parts and components in trade flows indicates more production-sharing between countries. 3 Using international input-output tables to depict inter-industry relations. I-O shows how the output of one industry is an input to each other industry. Input is enumerated in the column of an industry and its outputs are enumerated in its corresponding row. International I-O extends the inter-sectoral relations to several countries. It shows how dependent each national industry is on all other sectors from the domestic economy and from other partner countries, both as customer of their outputs and as supplier of their inputs. International I-O is conceptually very simple, but requires high-quality data. It is a powerful modeling tool for: Measuring size/magnitude of production linkages and the length of the chains Computing Vertical Specialization Index Tracking the international transmission of demand/supply shocks

8 Trade in services – offshoring/tasks Estimating the size of offshore outsourcing is subject to definitional and statistical challenges Classifications do not distinguish services to end-use clients or intermediate, or business-to- business services. Consequently, estimates vary - 2005: OECD's and UNCTAD include all IT-enabled services, estimate at US$836 billion. - 2007/8 UNCTAD estimated the value of trade in "IT-enabled" services at US$1.1 trillion in 2005,... - London School of Economics estimates global market of offshore outsourcing of IT (ITO) and business process services (BPO) to exceed US$55 billion in 2008, 20 per cent increasing annually over next five years. - Leading recipients of IT and business process off-shored trade have been Brazil, Russia, India, and China. Indias exports US$40 billion, China, Russia, and Brazil US$5 billion, US$3.65 billion, and US$800 million respectively in 2008. -------------------------------------------------------------  OECD, "Expanding International Supply Chains: The Role of Emerging Economies In Providing IT  and Business Process Services", Working Paper No. 52, May 2007.
