Accounting for a Community Economy

Part 9 of 10 in the 10,000 People Economy series.

A community economy can look impressive in a spreadsheet and still count the same activity three times.

A worker earns a wage. The household spends the wage at a local bakery. The bakery records a sale. If wages, spending and sales are added as separate contributions to output, one chain of transactions becomes three claims of value.

The opposite mistake is also possible. A model focuses only on household spending and ignores intermediate production, investment and sales to customers outside the community.

Good accounting stops the story from changing every time a different table is presented.

Every Product Needs a Destination

For each product, total supply must equal total use.

Supply comes from local production and imports. Use includes inputs into other production, household or public consumption, investment, inventory and sales outside the community.

If local firms produce R100 of goods and the community imports R30, the model must show where all R130 goes. It cannot count the same item as an input and a final product without recording the transformation between them.

This is why a job list is not an economy. Occupations tell us who might work. Supply-and-use accounts tell us what is produced, what production requires and who uses the output.

What the Current Model Says

In the year-five community scenario:

• domestic output is R4.029 billion;
• imports are R1.324 billion;
• local intermediate use is R431.568 million;
• imported intermediate use is R1.075 billion;
• household final consumption is R503.347 million;
• infrastructure formation is R161.026 million;
• capability formation is R13.825 million;
• inventories increase by R20.113 million; and
• external sales are R3.148 billion.

The table balances under its definitions. Modelled gross value added is R2.522 billion, or 62.61 per cent of domestic output.

That does not mean a real community has achieved those numbers.

It means the model has put each flow somewhere and avoided a basic accounting contradiction. The quantities, prices, producers, buyers and input shares still need observed evidence.

A Balanced Table Can Still Be Wrong

Accounting identities are powerful because they force consistency. They do not guarantee that the data are true.

A table can be balanced using incorrect prices. It can omit a purchased service and overstate value added. It can use national input ratios that do not fit the local industry. It can include external demand that no buyer has accepted.

For that reason, every important row needs a source, period, geography, unit, valuation basis and evidence status. Any adjustment used to force balance should remain visible.

Zero unexplained residual is one quality test. Source coverage is another.

Money Does Not Produce Electricity

Monetary accounting cannot settle physical feasibility.

If the model budgets R10 million for electricity, that does not show that the required kilowatt-hours, connection capacity and load profile exist. The same applies to water, food, land and materials.

Each resource needs its own balance in its own unit:

opening stock + local supply + imports = production use + household use + losses + exports + closing stock.

Electricity stays in energy and capacity units. Water stays in volume and flow units. Food stays in tonnes or nutritional equivalents. Land stays in hectares and capability classes.

Prices can be added afterwards. They cannot replace quantity.

The current model's average physical coverage is 53.1 per cent across its provisional baskets. That average should not be turned into a claim of "half self-sufficient". One essential resource at zero can bind the entire system. Source-gated physical cover therefore remains zero until the underlying evidence passes.

Imports Are Not Automatically Failure

A community economy does not need to make everything.

Imports can bring specialised equipment, medicine, inputs and knowledge that would be inefficient or impossible to produce locally. External sales can finance those imports and allow local producers to specialise.

The better questions are:

• Which imports are strategically unavoidable?
• Which dependence can be reduced economically?
• Can external sales generate reliable cash in time?
• What local value is retained after imported inputs?
• Which physical resources could interrupt production regardless of price?

Autonomy is the ability to maintain essential functions and negotiate external exchange. It is not isolation.

The Fieldwork Standard

Before a community account can support implementation, evidence gate E14 needs to identify real producers, real output, real inputs, real buyers, physical quantities and consistent prices.

The unbalanced data should be kept. The balancing decisions should be recorded. National tables can help classify and benchmark the local economy, but they should not be divided by population and presented as observed community production.

The year-five table is valuable because it creates a disciplined place for evidence to arrive. It tells us what must be measured and which totals must reconcile.

This is the proper role of accounting in an untested model. It cannot make the future certain, but it can make inconsistency much harder to hide.
