Introduction to the System of National Accounts (SNA) Lesson 8 Supply and Use Tables and Commodity Flow
Supply and Use Tables • In Lesson 1 welookedat a simplifiedSupply and Use Table (SUT). • SUTs are a first step in producing an Input-Output table. • SUTs are a means of ensuringthat GDP(P) and GDP(E) are equal. • «Commodity flow» is an SUT confined to a single good or service.
Worked examples for four commodities • Poultry meat • Mainly for household consumption but some is also intermediate consumption • Tobacco • In this example it is only for final consumption • Motor cars • Vehicles are both capital and consumption goods • Accountancy services • Intermediate and final consumption
Making Supply and Use Equal • Appraiseeachestimate in turn. • How reliableis the source • How doesthisyear’sestimate compare with last year’s? • Identify the weakestlink • Survey statisticianscan help here. • Decidewhether to accept the resdidualestimate or the direct estimate.
Second-hand Sales • Sales between households • The value of the vehicles cancells out • But dealers margins increase household consumption expenditure • Sales from government and enterprises to households • Negatve capital formation • Positive household consumption • Exports • Negatve capital formation or household consumption
What have we learned? • Supply and Use tables have 2 uses: • First step towards Input/Otput tables • Estimating consistent GDP • Commodity flow is a partial application of the SUT to: • Estimate a missing value • Consistency check • Applying commodity flow tables is challenging: • Assumptions are always needed. • Use all the information you can find.
