Global trade in goods and services, which today amounts to more than $20 trillion, includes a significant amount of double counting. Raw material extracted in one country may be exported first to a second country for processing, and then exported again to a manufacturing plant in a third country, which may then export it to a fourth for final consumption. Value added trade statistics can lead to important policy insights in the area of trade, investment and development. UNCTAD intends to deepen the analysis on how TNCs shape global and regional value chains and patterns of value added trade, to identify the drivers and determinants of investment in GVCs, and to assess the impact of GVCs, including by analyzing where and how employment and income is generated throughout.
