"A Model to Construct Time Series Databases for Global Trade, Production, and Consumption Linkages"
by Zhi Wang

There is resurgence in the applications of input-output (I-O) tables in the economic literature during recent years for both analytical and statistical purpose (Norihiko Yamano and Nadim Ahmad, 2006). As an analytical data source and accounting framework, input-output tables provide consistent analysis and measurement of vertical specialization of international trade (Hummels, Ishii, and Yi, 2001), domestic and foreign contents in a country’s gross exports (Koopman, Wang and Wei, 2008), the development of value-chain in global production network (Wang, Power and Wei, 2009), the pattern of gross versus value-added trade around the world (Johnson and Noguera, 2009), and trade flows in intermediate goods and services among OECD countries (Sébastien Miroudot, Rainer Lanz, and Alexandros Ragoussis, 2010). It is also increasingly being used in environmental analysis such as measuring direct and indirect pollutants produced by industrial sectors within an economy and estimate consumption-based emissions, thus accounting 'leakages' between economies (Davis and Caldeira, 2010), as well as current policy debate on the role of vertical specialization in the dramatic decline of world trade during recent global financial crisis(Bems, Johnson, and Yi, 2010) and the economic impact of global rebalancing (Petri, 2010). As a statistical analysis tool, input-output and the closely related supply-use tables are increasingly becoming the vehicles used to balance the income, expenditure and production estimates of GDP to satisfy the United Nation standards of System of National Account (SNA) 1993.
