The economy is large.
Is the market?
Why boards need more than GDP when assessing international opportunity.
A country’s GDP can make an investment proposal look persuasive before anyone has established who can afford the product.
This becomes clear when Denmark, Brazil and Indonesia are placed beside one another. IMF projections for 2026 put their nominal economies at approximately $504 billion, $2.64 trillion and $1.54 trillion. Introduce purchasing power parity and Indonesia reaches Int$5.45 trillion, slightly ahead of Brazil at Int$5.23 trillion. Denmark moves to Int$541 billion (IMF, 2026a; IMF, 2026b).
The figures are sound. Their business meanings are different. A board reviewing an international expansion needs to know which meaning belongs to the decision in front of it.

Economic scale changes with the measure

Affordability
Indonesia is easy to underestimate
At market exchange rates, Denmark’s projected GDP per person is about 15.6 times Indonesia’s. At PPP, the gap falls to approximately 4.7 times.
This does not make an Indonesian customer richer than their income allows. It reveals how much a direct dollar conversion misses. Locally earned money can travel further through parts of the domestic economy, especially where housing, food production and services are locally supplied.
A business that produces locally, employs local people and sells through domestic channels may therefore encounter far more depth than nominal income suggests. The answer changes when the offer relies on imported machinery, components bought in euros or dollar-denominated software. Those costs do not fall simply because domestic purchasing power is higher.
Indonesia contains very large domestic economic capacity and comparatively limited average ability to pay international prices.
Comparable size, different market
Brazil and Indonesia are not interchangeable
Indonesia is projected to become slightly larger than Brazil at PPP in 2026. Brazil retains a substantial lead in nominal GDP and produces more output per person under both measures.
Calling each a market of roughly five and a half trillion international dollars would conceal most of what management needs. Indonesia has around 73 million more people, a lower GDP per person and more than twice Brazil’s projected rate of real growth. Brazil brings higher average output, extensive urbanisation and a nominal economy approximately 71 per cent larger.
National averages combine affluent metropolitan customers, informal economic activity, remote communities and regions with sharply different infrastructure. GDP cannot reveal whether demand sits in São Paulo, Jakarta, secondary cities or industrial corridors. It says even less about the cost of reaching those customers.
The distance narrows after adjusting for prices

Decision discipline
Let the question choose the measure
| Board question | Evidence required | Commercial relevance |
|---|---|---|
| How large could domestic consumption become? | PPP GDP, population, household consumption and income distribution | PPP captures domestic price differences; population indicates potential volume. |
| Can customers afford our proposed price? | Median disposable income, target-segment income and product cost as a share of income | GDP per person is an average of output, not a customer budget. |
| What will local operations cost? | Wages, property, energy, logistics, taxes and supplier prices | National PPP cannot replace an operating-cost model. |
| What are revenues worth to the parent? | Exchange rates, repatriation rules and currency scenarios | PPP income cannot be converted into euros or dollars at the PPP rate. |
| Can we preserve margin? | Price elasticity, import content, duties, channel margins and currency exposure | Economic scale may not survive the realities of cost and achievable price. |
| Where does demand sit? | Regional income, urban concentration, customer data and distribution coverage | National averages hide commercially decisive differences within countries. |
One burger, one signal
What the Big Mac can tell a board
The Economist created the Big Mac Index as an informal illustration of purchasing power parity. A hamburger combines ingredients, labour, property, energy and local operating expenses, so its price contains more economic information than its simplicity suggests (The Economist, 2026).
For consumer affordability, working time required to buy the product can be more revealing than the converted price. Yet the burger remains a single branded product, influenced by taxes, franchise policy, local positioning and cultural demand. It cannot describe the affordability of housing, industrial equipment or software sold by a Danish technology company. The Federal Reserve Bank of St. Louis treats the index as an accessible illustration, rather than a comprehensive economic measure (Cook, 2024).
It can open a useful discussion. It cannot carry the investment case.
Commercial reality
From national economy to achievable revenue
Scale, growth, currency and political exposure
Value, regulation, maturity and competition
Customers with the need, location and access
Customers who can realistically afford the offer
Customers the company can acquire and support
Sales compatible with adoption, capacity, tax and execution
International business cases often weaken along this path. The opening slides describe a large country and a growing middle class. The revenue model then takes a small percentage of the national total and presents it as attainable. A modest percentage of an enormous number remains enormous. Arithmetic alone does not make it credible.
The boardroom test
The question worth taking into the meeting
How many customers can buy our offer, at a price they will accept and at a cost that allows us to create value?
A defensible answer should be traceable from national data to the target segment, then into price, cost-to-serve, currency exposure and achievable margin. Without that chain, the business case describes economic possibility rather than commercial opportunity.
