Why use the SUT framework ?Why use the SUT framework ?

Use of SUT framework ensures internally consistent data for each activity and product category.

Data from different sources appear in a systematic and organized fashion

Allows the compiler to eliminate inconsistencies and to identify and fill in data gaps

Allows compilation of more reliable values for GDP than those obtained by calculating GDP from the production, expenditure or income side separately

3

Use of SUTUse of SUT

SUT can be used as a compilation tool because the overall framework facilitates:

– data checking/reconciliation.– gap filling.

A number of countries treat SUT as central to their compilation process, not just as an irregular add-on needed to derive input-output tables.

The Supply TableThe Supply Table

The supply table containsThe supply table contains

Two transaction columns: Output at basic prices Imports c.i.f. and

Three adjustment columns: Taxes on products. Trade and transport margins; and C.i.f./f.o.b. adjustments.

5

The Use TableThe Use Table

The use table includes:The use table includes: Intermediate consumption; Final consumption; Gross capital formation; and Exports.

These transactions are valued at purchasers’ prices; i.e. the valuation includes taxes on production and imports, as well as trade and transport margins for each individual set of numbers.

Derivation of Supply Table Derivation of Supply Table at basic pricesat basic prices

Market output = Sales

+ Change in inventories (FG and WIP)  Non-market output (= Cost of production)

= Intermediate consumption + Compensation of employees + Other Taxes less subsidies on production + Consumption of fixed capital

10

Derivation of SupplyTable Derivation of SupplyTable at basic pricesat basic prices

Intermediate consumption = Purchases - Change in inventories (materials)

Value added = Output - Intermediate consumption  Operating surplus = Value added - Compensation of employees - Taxes less subsidies on production - Consumption of fixed capital

11

Transport MarginsTransport Margins

 When is the cost of transportation to be treated as a transport margin?

  Transport margins consist of transport charges paid

separately by the purchaser to take delivery at a required time and place (SNA 15.28)

  If not paid separately, the transport cost could be

included as part of the basic price of the good, part of the wholesale or retail margin, or as an expense of the purchaser.

12

Trade MarginsTrade Margins

A trade margin (wholesale or retail trade) applies only when there is a distribution service provided by the trader through buying and reselling a product.

A trade margin does not apply to direct sales by a producer, even when the sales are to households.

13

Trade MarginsTrade Margins

Trade margin is defined as the difference between the selling price of the good for resale and the price that would have to be paid by the distributor to replace the good at the time it is sold.

The trade margin is the output of the distributor. As with other producers, value added is obtained by subtracting intermediate consumption.

14

Trade MarginsTrade Margins Broadly, the trade margin is calculated as:

– Sales – less purchases of goods for resale– plus change in inventories for resale

– Note: purchases of goods for resale should exclude any transport charges invoiced separately to the distributor; such transport charges are to be shown as intermediate consumption of the distributor. (SNA 6.112)

The trade margin is part of the difference between the basic price of a good and its purchasers’ price.

15

Trade MarginsTrade Margins Data sources for trade margins:

– Total margin earned from establishment data.– Margins for broad commodity groups.– Markup rates for particular kinds of goods– Supply/use of the goods subject to the margin. 

Balancing process to fit available, but incomplete, data. Much prorating in practice. Separate margin calculations for wholesale, retail, and

other? Yes, if different usage patterns and data available to do so.

16

Treatment of ImportsTreatment of Imports

Consistent with the Balance of Payments Manual in valuing imports of goods in total on a f.o.b. basis, and to show international transportation as a service.

However, in the Supply/Use framework, imports at the commodity level are valued on a c.i.f. basis (including international transportation).

A c.i.f./f.o.b. adjustment is made in the Supply table to accommodate these two valuation bases, and to ensure that domestic carriage of imports is not double counted.

17

Treatment of ImportsTreatment of Imports

Example of c.i.f./f.o.b. adjustment:

– Assume imports c.i.f. = 1,000 f.o.b. = 900

– International transportation = 100– Domestic carriers = 20– Foreign carriers = 80

– Assume domestic transportation to the user = 30

18

Treatment of ImportsTreatment of Imports

Therefore,

– imports of goods f.o.b. = 900– imports of services = 80– Domestic services = 20 + 30 = 50– Supply at purchasers’ prices = 1,030

The c.i.f./f.o.b. adjustment ensures that these values are reflected in the Supply table.

19

Steps for compilation of SUT Steps for compilation of SUT

Step 1: Design of classifications and conversion keys specific to the country.

Conversions are best carried out in Access. Results are subsequently imported to Excel

Step 2: Construction of files where data from

individual sources are treated

Step 3: Setting up of a computerised system for the balancing of supply and use by product category

20

Balancing supply and use Balancing supply and use transactions consists of two main transactions consists of two main

steps:steps:1. Manual balancing: Requires a great deal of judgment of the national

accountant. Procedure is largely a matter of trial and errors where

statistical discrepancies are eliminated step by step. 2. Mechanical balancing: Final part of the balancing exercise and requires no

further judgment on the part of the national accountant. It is not done until remaining discrepancies are so small

that they are devoid of economic or analytical meaning.

21

ExamExamples of adjustments within ples of adjustments within the manual balancing processthe manual balancing process

Evaluate input / output structures of all columns to identify data gaps, and checking potential coding and classification problems (activity or vertical dimension);

Identify anchors – i.e. identify which transactions are most reliable, and therefore least subject to change.

Analyze and gradually eliminate discrepancies between supply and use for all rows of the SUT (product or horizontal dimension);

Finalize adjustments to input / output structures by activity, and make conclusive checks of product balances.

22

Adjusting imports and exportsAdjusting imports and exports

Importers have an incentive to under-invoice. In addition, it is very probable that some smuggling occurs.

For exports, the incentive to under-invoice is weaker. It might be relevant to increase export data as well, but usually with a smaller percentage increase.
