Trade in value-added (TiVA)
Decomposes gross trade flows into the value contributed by each country in a global value chain. An iPhone exported from China contains components from many countries; TiVA reveals that.
Standard trade statistics record gross flows (the full value of an exported iPhone counts as a Chinese export). TiVA databases instead split that value among every country whose firms contributed (Korean displays, US chips, Japanese sensors, Chinese assembly). The OECD-WTO TiVA database is the leading source, available for 76 economies and 45 industries with a 4-year lag.
Examples
- A Chinese-assembled iPhone may contain only ~5% Chinese value-added.
- TiVA shows that Germany's "exports" embed ~25% imported intermediates from Eastern Europe.
