The OECD-WTO Trade in Value Added (TiVA) database, first launched in January 2013, has transformed the way we view trade, providing a prism that provides unique insights on the nature of GVCs.
The production of TiVA indicators is a significant data-intensive process, requiring national (input-output and supply-use) data that are not typically available until around three years after the reference period they measure. This has meant that current TiVA estimates have significant time lags. To address this issue and meet the high demand for more timely TiVA estimates, the OECD has developed a ‘now-casting’ approach to generate indicators for more recent periods. This first release of nowcast TiVA data includes estimates up to 2014 (i.e a lag of just under three years). Plans are in place to develop estimates with a lag of less than two years and work is on-going to develop methods and approaches that improve further on these lags.
The OECD nowcast estimates are derived from a number of different data sources, including the 2011 TiVA relationships; national Supply-and-Use tables; merchandise trade statistics; trade in services statistics; and the core national accounts. The OECD source datasets can be accessed below:
