Shorter explanation in UN SNA 2008:
Chapter 14: The supply and use tables and goods and services account
14.2 Term “product” now used instead of “commodity” for both flow and balance.
14.4 Product balance:
Turnover = productive consumption + consumption + accumulation
Output + imports = intermediate consumption + final consumption + capital formation + exports
Worth showing imports and exports even though set to 0 for now as will be needed later, for multiple local and regional as well as national tables with transport and trade margins. Will also need taxes and subsidies later.
14.5 Both sides at purchasing prices so add above extras to left side:
Output (at basic prices) + imports + trade margins + transport margins + taxes on products – subsidies on products = (at purchaser’s prices)
intermediate consumption + final consumption + capital formation + exports
Again, we set these extras to 0 for now.
Chapter 28: Input-output and other matrix-based analyses
Also describes Social Accounting Matrix.
