OECD Science, Technology and Industry Working Papers
The OECD Directorate for Science, Technology and Innovation (STI) leads OECD research on the contribution of science, technology and industry to well-being and economic growth. STI Working Papers cover a broad range of topics including definition and measurement of science and technology indicators, global value chains, and research on policies to promote innovation. These technical or analytical working papers are prepared by staff or outside consultants to share early insights and elicit feedback.

Towards Harmonised Bilateral Trade Data for Inter-Country Input-Output Analyses: Statistical Issues
Understanding the increasingly complex structures of international trade is an important concern for
policy makers, as deepening economic integration is characterised by the growing trade in intermediate
goods and services between countries. Analyses based on international input-output tables can help address
trade-related policy issues as well as providing other insights into the socio-economic and environmental
impacts of globalisation. To link national input-output tables in order to carry out interdependent analyses
across countries requires a consistent set of harmonised international bilateral trade data that ideally
reflects recent output by the economic activities in question. This paper discusses the challenges faced
when attempting to construct appropriate bilateral trade matrices using annual data collected by the OECD
and United Nations, as well as national sources. While the main focus is on the increasing presence of
“re-exports” in reported exports of goods data, this paper also addresses some other statistical and data
issues that need to be considered, such as treatment of confidential (or “unallocated”) trade in goods; trade
in secondhand goods, scrap metal and other waste; differences in trade statistics across international
statistical agencies; and the additional problems encountered when converting product-based trade data to
industry-based classifications. Issues concerning Balance of Payments data, the main source for trade in
services, are also addressed.
