What STRLDi members must know about Economics

The Economic Concepts, Terms and Relationships Required for Systems Leadership

An STRLDi Learning & Leadership Paper

Economic literacy for a systems leader is not the ability to recite definitions from an economics textbook. It is the ability to see how an economy actually works as a system—how people, households, enterprises, capital, production, demand, infrastructure, trade, government and money interact over time.

For STRLDi members, this distinction is important. We are not training conventional economists. We are training people who must be able to diagnose persistent national problems, recognise structural constraints, understand economic flows, interrogate numbers, and design conditions under which productive capacity can grow.

The STRLDi National Economic Operating System therefore requires members to understand economics sufficiently well to ask a different class of question: What is the structure producing the number we are observing?

The STRLDi economic architecture begins from population and moves through capability, enterprise, production, demand, goods, money and control. The economic system is therefore understood not as a collection of disconnected indicators, but as a set of interacting flows that must be deliberately sized and coordinated. (STRLDi)

1. THE FIRST DISTINCTION: STOCKS, FLOWS AND RATES

Before learning economic indicators, STRLDi members must understand the difference between a stock, a flow, and a rate.

Concept	Meaning	Example
Stock	Something accumulated at a point in time	Capital, population, debt, infrastructure
Flow	Something moving over a period	GDP, exports, investment, wages
Rate	A flow expressed relative to another quantity or time	Growth rate, unemployment rate, return on investment
Capacity	The amount the system can produce or absorb	Production capacity, school capacity, logistics capacity
Utilisation	How much of existing capacity is actually being used	Factory utilisation
Productivity	Output generated from an input	GVA per worker

Systems-thinking implication: A country can have a large stock of infrastructure and still have weak economic flows. It can also have a growing population stock without having sufficient productive capacity to absorb the people entering the working-age population.

2. GDP, GVA AND ECONOMIC OUTPUT

These are among the most important concepts STRLDi members must understand precisely.

Term	What it tells us	STRLDi relevance
GDP	Monetary value of final goods and services produced within an economy	Measures overall economic output
GVA	Value added by productive sectors before product taxes/subsidies	Useful for examining productive structure
Gross output	Total value of production before intermediate inputs are deducted	Shows scale of economic activity
Intermediate consumption	Goods and services consumed in producing other goods/services	Prevents double-counting
Value added	Output minus intermediate consumption	Shows value actually created
GDP per capita	GDP divided by population	Broad average output per person
GVA per worker	GVA divided by workers	Direct productivity indicator
Real GDP/GVA	Output adjusted for price changes	Measures volume/productivity change
Nominal GDP/GVA	Output measured at current prices	Includes price changes
Potential output	Output the economy could produce at sustainable capacity	Critical for capacity planning
Output gap	Difference between actual and potential output	Indicates unused or overstretched capacity

The STRLDi model deliberately gives particular attention to GVA per worker, because the central question is not simply whether the economy becomes larger, but whether the population becomes capable of producing substantially more value. The published operating model therefore distinguishes between the population load and the productive value generated per worker. (STRLDi)

3. PRODUCTIVITY — THE NUMBER STRLDi MEMBERS MUST LEARN TO SEE

Productivity is one of the most important concepts in the entire STRLDi economic framework.

A country can employ more people without becoming substantially more productive. Conversely, a country can increase output significantly without proportionally increasing employment if each worker operates within a more productive system.

Measure	Basic question
Labour productivity	How much output/value does each worker produce?
Capital productivity	How much output is produced from capital employed?
Total factor productivity	How effectively are labour and capital combined?
Land productivity	How much output/value is generated per unit of land?
Energy productivity	How much output is generated per unit of energy?
Water productivity	How much economic value is generated per unit of water?

The critical STRLDi distinction is:

Employment tells us how many people are inside the economy. Productivity tells us what the economy is capable of doing with them.

This is why simply achieving a 90:10 employment structure is insufficient. The STRLDi model explicitly distinguishes who absorbs the population from how much productive value that population generates. (STRLDi)

4. GROWTH IS NOT THE SAME AS TRANSFORMATION

STRLDi members must be able to distinguish economic growth from structural transformation.

Concept	Meaning
Economic growth	Increase in economic output
Per-capita growth	Increase in output relative to population
Productivity growth	Increase in output/value per input
Structural transformation	Movement of resources into higher-productivity activities
Diversification	Reduction of excessive dependence on a small number of sectors/products
Industrialisation	Expansion of productive industrial capability
Value addition	Increasing the value retained through processing/manufacturing
Economic upgrading	Moving into higher-value products, processes and markets

This distinction is central to the Scenario A/Scenario B reasoning.

A country may grow from one economic size to another while remaining structurally poor if the underlying productivity and value-creation architecture does not change.

The STRLDi operating model therefore treats Scenario A as a trajectory that can produce a larger nominal economy without necessarily producing the structural transformation required to alter productivity, enterprise capability and household economic outcomes. (STRLDi)

5. POPULATION ECONOMICS

For STRLDi, population is not merely a demographic statistic.

It is a system load.

Members must understand:

population growth;
age structure;
dependency ratios;
working-age population;
labour-force participation;
household formation;
migration;
urbanisation;
population density;
demographic transition;
population projections.

The key systems question becomes:

What physical, institutional and productive capacity must exist when this population reaches the next stage of its life cycle?

The STRLDi model uses Botswana’s 2022 population baseline of approximately 2.36 million and examines a planning envelope reaching 3.29 million within five years and 4.05 million within twenty years under its migration-stress scenario. (STRLDi)

6. LABOUR ECONOMICS

Members must understand the difference between population, labour force and employment.

Term	Meaning
Working-age population	People within the defined working-age range
Labour force	People working or actively seeking work
Employed	People engaged in economic activity
Unemployed	People without work who are available and seeking work under the statistical definition
Labour-force participation rate	Labour force as a share of working-age population
Employment-to-population ratio	Employed people as a share of working-age population
Underemployment	Labour employed below its potential or desired level
Informal employment	Work outside formal employment structures
Youth unemployment	Unemployment among the specified youth age group
Structural unemployment	Unemployment arising from structural mismatch in the economy
Frictional unemployment	Temporary unemployment associated with movement between jobs

The STRLDi question

The conventional question is:

How do we get unemployed people into jobs?

The systems question is:

Where is the productive capacity into which these people can actually enter?

The STRLDi National Economic Operating System explicitly reframes persistent unemployment as a capacity and architectural problem, rather than simply a job-matching problem. (STRLDi)

7. CAPITAL

Members must understand that capital is not simply money.

Type	Examples
Financial capital	Money, credit, equity
Physical capital	Machinery, factories, vehicles
Infrastructure capital	Roads, electricity, water systems, logistics infrastructure
Human capital	Knowledge, skills and capabilities
Organisational capital	Processes, systems, institutional capability
Natural capital	Land, water, ecosystems and natural resources
Intellectual capital	Knowledge, technology, intellectual property
Social/relational capital	Trust, cooperation and networks

A systems leader must therefore ask:

Which form of capital is constraining the system?

A farmer may have land but lack water infrastructure.
A factory may have machinery but lack working capital.
A graduate may have qualifications but lack an enterprise into which the capability can flow.

The constraint is therefore not always money.

8. INVESTMENT

Investment is the creation or acquisition of productive capacity.

Members should understand:

gross fixed capital formation;
public investment;
private investment;
foreign direct investment;
domestic investment;
working capital;
asset finance;
infrastructure investment;
reinvestment;
depreciation;
return on investment;
cost of capital;
hurdle rates.

The central systems question is:

What capacity does the investment create, and what future flow does that capacity make possible?

Investment that creates an asset without creating a productive flow may not transform the economy.

9. RETURN ON INVESTMENT AND HURDLE RATES

A systems leader must understand why capital moves toward some activities and away from others.

Concept	Question
ROI	What return does the investment generate?
ROIC	What return is generated on invested capital?
Hurdle rate	What minimum return must an investment achieve?
Cost of capital	What does it cost to obtain and use capital?
Payback period	How long before the investment recovers its cost?
Risk-adjusted return	Is the return adequate for the risk?
Capital intensity	How much capital is required per unit of output/worker?

The STRLDi model uses sector-specific hurdle rates as part of determining whether capital can be allocated into productive enterprise at sufficient scale.

10. MONEY IS A FLOW, NOT THE ECONOMY ITSELF

STRLDi members must resist the common mistake of treating money as synonymous with economic value.

Money is the medium through which economic value is exchanged and measured.

The real system is:

Resources → capability → production → value → demand → sale → revenue → wages/profit/tax → reinvestment → expanded capacity

This is why the STRLDi model explicitly constructs a money pipeline alongside the physical goods pipeline.

Its basic loop is:

Customer → Payment → Enterprise Revenue → Wages → Supplier Payments → Finance → Tax → Profit → ROI → Reinvestment

The critical systems question is:

Does the money return to the productive system, or does it leak out before productive capacity is renewed?

11. DEMAND

Demand is not merely “people wanting something.”

Members must understand:

effective demand;
consumer demand;
intermediate demand;
domestic demand;
regional demand;
international demand;
contracted demand;
latent demand;
demand forecasting;
purchasing power;
market size;
market access;
buyer specifications.

This is fundamental to the STRLDi pipeline.

Production without defined demand creates risk.

The STRLDi model therefore reverses the conventional sequence:

Find and define demand → organise production → move product → settle payment.

The published operating system explicitly treats demand visibility as a national economic asset and introduces the Demand Definer and Corridor Operator as distinct organisational nodes. (STRLDi)

12. SUPPLY

Members must understand the other side of the market.

Supply involves:

productive capacity;
input availability;
labour;
land;
water;
energy;
machinery;
technology;
finance;
logistics;
inventories;
production lead times;
quality;
reliability.

A critical systems distinction is:

Current production is not the same as productive capacity.

A country may currently produce 14,000 tonnes of a product while having a national demand requirement of 20,000 tonnes.

The 6,000-tonne gap is therefore not merely a market statistic. It is a signal of missing productive capacity.

13. MARKETS AND PRICE

Members must understand the basic mechanics of:

supply and demand;
price formation;
elasticity;
substitutes;
complements;
competition;
monopoly;
oligopoly;
market power;
price signals;
price volatility.

But STRLDi members must go beyond textbook market diagrams.

The systems question is:

What structure is producing the price?

A high price may signal scarcity.

A low price may signal oversupply.

A volatile price may signal unstable supply, demand, exchange rates, trade conditions or commodity cycles.

A market failure may arise because the institutions required for the market to function do not exist.

14. VALUE CHAINS

A value chain shows how value moves from input to final customer.

For example:

Seed → Farm → Aggregation → Quality Control → Processing → Manufacturing → Packaging → Logistics → Retail → Consumer

Members must understand:

upstream;
downstream;
vertical integration;
horizontal integration;
value capture;
value addition;
margins;
bottlenecks;
transaction costs;
lead times;
quality control;
supply-chain coordination.

This is one of the most important economic concepts in STRLDi because a country may produce a commodity while capturing very little of the value generated from that commodity.

15. VALUE ADDITION

Value addition asks:

What additional economic value is created before the product reaches the customer?

A raw agricultural product may become:

Raw material → processed ingredient → manufactured product → branded product → export product

Each stage can potentially create:

additional wages;
enterprise revenue;
technical capability;
tax revenue;
export value;
intellectual property;
reinvestment capacity.

This is why manufacturing occupies a central position in Scenario B.

16. TRADE

STRLDi members must understand:

exports;
imports;
trade balance;
terms of trade;
trade openness;
tariffs;
quotas;
non-tariff barriers;
sanitary and phytosanitary standards;
rules of origin;
trade agreements;
customs;
border logistics;
import dependence;
export competitiveness.

The systems question is not simply:

Are we exporting?

It is:

What are we exporting, what are we importing, where is value being created, and where is value being lost?

17. COMPETITIVENESS

Competitiveness is the ability to produce and sell successfully against alternatives.

It depends on:

Productivity + quality + reliability + cost + logistics + technology + skills + finance + market access + institutional conditions.

Low wages do not automatically create competitiveness.

A country can have cheap labour and still be globally uncompetitive if:

productivity is low;
logistics are expensive;
electricity is unreliable;
production volumes are inconsistent;
quality is poor;
financing is expensive;
borders are slow.

18. INFLATION

Members must understand inflation because nominal numbers can deceive.

Term	Meaning
Inflation	Sustained increase in general price levels
Deflation	Sustained decline in general price levels
Real value	Value adjusted for price changes
Nominal value	Value at current prices
Purchasing power	What money can actually buy
CPI	Consumer price index
Real wage	Wage adjusted for inflation

This is particularly important when comparing wages and GDP across time.

A larger nominal economy does not automatically mean a more productive economy.

19. EXCHANGE RATES AND PPP

Members working with international comparisons must understand the difference between:

Market exchange rates and Purchasing Power Parity (PPP).

Measure	Useful for
Market exchange rate	International financial transactions
PPP	Comparing purchasing power and living standards across countries
Nominal USD	Market-converted monetary comparison
PPP-adjusted USD	Cross-country purchasing-power comparison

The distinction matters when comparing Botswana’s household wages or productivity with international benchmarks.

20. FISCAL POLICY

Members must understand how government raises and spends money.

Key concepts include:

taxation;
government expenditure;
fiscal deficit;
fiscal surplus;
public debt;
debt service;
public investment;
subsidies;
transfers;
public procurement;
fiscal multiplier;
fiscal sustainability.

But STRLDi members should always ask:

What does government expenditure change in the underlying system?

A programme may spend money without increasing productive capacity.

Another expenditure may create infrastructure that enables thousands of future transactions.

The expenditure number alone does not tell us which has happened.

21. MONETARY POLICY

Members should understand:

money supply;
interest rates;
inflation;
central banking;
liquidity;
credit conditions;
exchange-rate effects;
monetary transmission.

The essential systems relationship is:

Interest rate → cost of capital → investment → enterprise formation → production → employment → demand

Changes in monetary conditions therefore propagate through the wider economic system.

22. GOVERNMENT FAILURE, MARKET FAILURE AND SYSTEM FAILURE

These must not be treated as interchangeable.

Failure	Basic issue
Market failure	Markets do not efficiently allocate resources under particular conditions
Government failure	Public intervention produces inefficient or unintended outcomes
Institutional failure	Rules or institutions cannot perform their intended function
Coordination failure	Multiple actors cannot align actions even where mutual benefit exists
Information failure	Relevant information is absent, distorted or inaccessible
System failure	Interacting structures continually reproduce the undesirable outcome

This final distinction is particularly important for STRLDi.

A persistent unemployment problem may survive repeated government programmes because the structure generating unemployment remains unchanged.

23. ECONOMIC MULTIPLIERS AND LEAKAGES

Members must understand that economic activity can produce secondary effects.

An initial expenditure may generate:

Income → consumption → additional income → additional demand → additional production

But money can also leak from the system through:

imports;
debt servicing;
capital flight;
savings;
external ownership;
remittances;
inefficient procurement.

The systems question becomes:

How much of each Pula remains circulating through productive domestic activity?

24. ENTERPRISE DENSITY

A country cannot achieve a private-sector-led economy simply by declaring that the private sector should employ more people.

There must be enough organisations.

Members must understand:

enterprise formation;
firm size;
SMEs;
medium-sized enterprises;
large corporations;
clusters;
supply networks;
subcontracting;
enterprise survival;
firm productivity;
enterprise scaling.

This is why STRLDi uses enterprise sizing rather than simply employment targets.

The operating model explicitly calculates enterprise categories and their required scale across five-, ten- and twenty-year horizons. (STRLDi)

25. ECONOMIC DENSITY

STRLDi members should learn to see density.

A productive economy has density in:

enterprises;
suppliers;
skills;
infrastructure;
finance;
logistics;
buyers;
technology;
knowledge;
institutions.

One factory does not create an industrial economy.

A functioning industrial system requires an ecosystem around the factory.

This is the logic behind the STRLDi emphasis on corridors, clusters, aggregation nodes, manufacturing enterprises, logistics enterprises and demand intelligence.

26. ECONOMIC CORRIDORS

A corridor is not simply a road.

An economic corridor connects:

Production + infrastructure + logistics + processing + markets + finance + information

The STRLDi Agriculture Corridor Execution Lattice therefore treats logistics, aggregation and transport as core components of the productive system, rather than auxiliary services.

This is a critical systems-thinking distinction.

27. ECONOMIC BOTTLENECKS

A bottleneck is the constraint that limits the throughput of the system.

Examples:

insufficient water;
inadequate electricity;
limited cold storage;
insufficient processing capacity;
border delays;
lack of finance;
inadequate technical skills;
insufficient demand;
poor logistics;
regulatory delay.

The critical STRLDi question is:

Which constraint currently limits the throughput of the entire system?

Not every problem deserves equal intervention.

28. THROUGHPUT

Throughput is the amount of value or physical product successfully moved through a system over a period.

For STRLDi, throughput is particularly important because the economic system is ultimately concerned with movement:

People → capability → enterprise → production → goods → markets → payment → reinvestment

A system with enormous installed capacity but low throughput is not a productive system.

29. TRANSACTION COSTS

Members must understand the economic cost of making transactions happen.

These include:

searching for buyers;
negotiating contracts;
compliance;
transport;
information gathering;
customs;
financing;
quality verification;
contract enforcement.

The Demand Definer and Corridor Operator architecture is partly a response to these coordination costs: the system does not expect an individual producer to carry the entire burden of negotiating and fulfilling large-scale demand.

30. HUMAN CAPITAL VERSUS ORGANISATIONAL CAPABILITY

This is a crucial STRLDi distinction.

A country can possess educated people without possessing productive organisations capable of using their capabilities.

Therefore:

Education ≠ capability utilisation.

And:

Capability ≠ productive output until an organisation exists through which capability can operate.

This is why the STRLDi pipeline moves:

Family → Learning → Capability → Enterprise → Production

rather than stopping at education.

The National Economic Operating System explicitly positions family, learning, capability and enterprise as sequential organisational nodes through which people enter productive economic activity. (STRLDi)

31. THE ECONOMICS OF SCALE

Members must understand why some activities become more productive as they grow.

Key concepts:

economies of scale;
diseconomies of scale;
fixed costs;
variable costs;
average cost;
marginal cost;
capacity utilisation;
specialisation.

This matters directly to the STRLDi concern with moving beyond fragmented survivalist enterprises toward scaled, coordinated enterprises.

32. MARGINAL THINKING

Economics often asks:

What happens if we add one more unit?

Members should understand:

marginal cost;
marginal revenue;
marginal productivity;
marginal benefit;
marginal utility.

But systems leaders must add another question:

What happens to the rest of the system when this marginal change occurs?

That is where systems thinking extends conventional economic analysis.

33. OPPORTUNITY COST

Every decision excludes alternatives.

If P1 billion is invested in one type of infrastructure, it cannot simultaneously be invested elsewhere.

Opportunity cost therefore asks:

What productive possibility are we giving up by choosing this one?

This is indispensable for national investment decisions.

34. ECONOMIC RENT AND RESOURCE DEPENDENCE

Members must understand:

economic rent;
resource rent;
mineral rents;
scarcity rents;
rent-seeking;
resource dependence;
commodity cycles.

A mineral-dependent economy can generate substantial income without developing broad-based productive capability.

This is precisely why STRLDi distinguishes between extractive value and downstream value creation.

35. ECONOMIC DIVERSIFICATION

Diversification is not simply having more industries.

A meaningful diversification strategy asks:

Are sectors productive?
Are they connected?
Do they share infrastructure?
Do they create domestic supply chains?
Do they generate exports?
Do they retain value domestically?
Do they create capabilities that enable further diversification?

Diversification without productivity can simply create more low-value activity.

36. THE 90:10 ARCHITECTURE

The 90:10 National Economic Architecture is a central STRLDi structural proposition.

It distinguishes between:

90% — private/commercially productive economic absorption

and

10% — public institutional capacity required to govern, regulate, provide public goods and hold system conditions.

The crucial point is that this is not simply an employment statistic.

It is an operating architecture.

The STRLDi model explicitly states that the 90:10 structure solves who absorbs the population, while sectoral productivity determines how much value that population produces. (STRLDi)

37. THE DUAL CONTROL LOOP

Members must understand the difference between running the economy and holding the conditions under which the economy operates.

Public Loop

Demand visibility → Rules → Standards → Infrastructure → Permission → Performance data → Numerical judgement → Correction

Private Loop

Buyer contract → Production allocation → Inputs → Execution → Aggregation → Logistics → Delivery → Payment → ROI → Reinvestment

The distinction is foundational:

The public sector holds the system. The private sector runs the flow.

The two loops must connect through data, but they should not unnecessarily duplicate one another. (STRLDi)

38. ECONOMIC DATA AND INDICATORS

STRLDi members must become comfortable reading numbers.

At minimum, members should be able to interpret:

Indicator	What it helps reveal
GDP/GVA	Economic output
GDP/GVA growth	Change in output
GVA per worker	Productivity
GDP per capita	Average output per person
Employment	Labour absorption
Unemployment	Labour underutilisation
Labour participation	Engagement with labour market
Inflation	Purchasing-power pressure
Wage growth	Household income movement
Investment	Capacity formation
Exports	External demand
Imports	External dependence
Trade balance	External goods balance
Current account	Broader external position
Public debt	Government financial burden
Fiscal deficit	Government financing gap
Manufacturing share	Industrial value creation
Agriculture share	Agricultural economic contribution
Services share	Service-sector contribution
FDI	Foreign investment flow
Productivity	Efficiency of production

39. THE MOST IMPORTANT QUESTION: WHAT IS THE NUMBER DIVIDED BY?

An STRLDi member should never accept a large economic number without asking:

Compared with what?

A P1 trillion economy may sound enormous.

But divide it by:

population;
workers;
households;
enterprises;
years;
capital invested;
sector;
physical output.

The meaning changes.

This is one of the most important habits of economic systems leadership.

40. NOMINAL VERSUS REAL

Members must be able to distinguish:

Nominal growth

from

real growth.

If an economy grows from P500 billion to P600 billion while prices rise substantially, the apparent increase does not necessarily represent an equivalent increase in physical productive capacity.

Therefore:

Never interpret nominal economic growth as productivity growth without examining the price effect.

41. THE ECONOMIC BASELINE

Every STRLDi economic intervention should establish:

Where are we now?

That means identifying:

population;
workforce;
unemployment;
productivity;
sector structure;
enterprise structure;
capital stock;
infrastructure;
demand;
exports;
imports;
government expenditure;
wages;
investment;
constraints.

Only then can a future state be meaningfully sized.

42. THE TRAJECTORY

A baseline is a point.

A trajectory is movement through time.

STRLDi members should therefore learn to ask:

Where are we going if nothing changes?

and then:

Where could we go if the structure changes?

The STRLDi National Economic Operating System uses precisely this distinction through its Scenario A versus Scenario B architecture. (STRLDi)

43. SCENARIO ANALYSIS

Scenario analysis is not prediction.

It asks:

If these structural assumptions remain in place, what trajectory follows?

and:

If we change these structural conditions, what different trajectory becomes possible?

This is why Scenario A and Scenario B should not be interpreted simply as “forecast A” and “forecast B”.

They represent different system architectures.

44. THE PRICE OF WAITING

This is perhaps the most important economic concept for STRLDi national leadership work.

Waiting has an economic cost.

If population continues growing while productive capacity remains unchanged, the country does not remain stationary.

The gap between:

Population growth

and

capacity growth

becomes a structural deficit.

The STRLDi “Ground Is Moving” analysis therefore frames the issue as a timing problem as well as a productivity problem: the population continues moving through the system whether or not the country has built the capacity required to receive it. (STRLDi)

45. THE STRLDi ECONOMIC READING FRAME

Ultimately, STRLDi members should learn to read any national economic issue through eight questions:

Question	What we are looking for
1. How many people?	Population load
2. What capacity exists?	Physical and organisational capacity
3. What does each unit produce?	Productivity
4. Who demands it?	Market/demand
5. How does it move?	Value chain/corridor
6. Where does the money go?	Financial flow
7. Who controls what?	Public/private control architecture
8. What happens next?	Dynamic trajectory

This converts economics from a collection of disconnected indicators into a system of relationships.

46. THE STRLDi ECONOMIC VOCABULARY

Every STRLDi member should eventually be completely comfortable with the following terms:

GDP · GVA · GVA per worker · productivity · output · capacity · utilisation · population · labour force · unemployment · employment · participation · wages · inflation · real value · nominal value · capital · investment · ROI · ROIC · hurdle rate · cost of capital · demand · supply · market · price · elasticity · value chain · value addition · manufacturing · industrialisation · diversification · competitiveness · exports · imports · trade balance · exchange rate · PPP · fiscal policy · monetary policy · public debt · deficit · taxation · enterprise density · economies of scale · marginal productivity · opportunity cost · transaction costs · bottlenecks · throughput · infrastructure · human capital · organisational capability · economic rent · resource dependence · structural transformation · scenario analysis · economic trajectory.

But knowing the vocabulary is only the beginning.

The real STRLDi capability is being able to connect the terms.

47. THE ECONOMY AS A SYSTEM

The ultimate learning progression should therefore be:

Population

↓

Household Formation

↓

Learning & Capability

↓

Enterprise Formation

↓

Productive Capacity

↓

Defined Demand

↓

Production

↓

Aggregation & Quality

↓

Processing & Manufacturing

↓

Logistics & Markets

↓

Revenue

↓

Wages + Profit + Tax

↓

ROI

↓

Reinvestment

↓

Expanded Productive Capacity

↓

Absorption of the Next Population Increment

This is the economic logic underlying the STRLDi National Economic Operating System. (STRLDi)

CONCLUSION

STRLDi members do not need to become economists in the conventional sense.

They need to become economically literate systems leaders.

That means being able to look at a country’s unemployment number and ask what capacity structure produced it; to look at GDP and ask what productivity produced it; to look at population and ask what future system load it represents; to look at investment and ask what productive capacity it creates; to look at trade and ask where value is retained; and to look at government expenditure and ask whether it changes the underlying system or merely manages its symptoms.

The discipline is therefore not:

“Know economics.”

It is:

Know enough economics to see the system that the numbers are describing.

That is the level of economic literacy required if STRLDi is to move from diagnosing persistent national problems to designing the systems capable of changing their trajectories.

STRLDi TEAM ASSIGNMENT

Economic Concepts: Determine the Formula, Meaning and Use

Assignment Purpose

The team is required to move beyond knowing economic terminology. For each selected concept, determine the complete mathematical formula, define every component in the formula, identify the unit of measurement, and explain what the resulting number tells us about the economy.

The objective is to build the economic numeracy required for STRLDi systems work: to be able to move from a national number → to its calculation → to its meaning → to the structural condition it reveals → to the decision it can inform.

PART I — THE CORE ECONOMIC NUMBERS

These are the concepts every STRLDi member should be able to calculate and interpret without assistance.

#	Concept	Formula the team must determine	What the team must explain
1	GDP	Full expenditure / production / income formulation	What GDP measures and what it does not measure
2	GVA	Output − Intermediate Consumption	How value is actually created within sectors
3	GDP per Capita	GDP ÷ Population	What average output per person reveals
4	GVA per Worker	GVA ÷ Number of Workers	The core measure of labour productivity used in the STRLDi analysis
5	Labour Productivity Growth	Change in output per worker over time	Whether workers are becoming more productive
6	GDP/GVA Growth Rate	Change in real GDP/GVA ÷ previous GDP/GVA × 100	Whether economic output is expanding or contracting
7	Unemployment Rate	Unemployed ÷ Labour Force × 100	The proportion of the labour force without employment
8	Labour-Force Participation Rate	Labour Force ÷ Working-Age Population × 100	How much of the working-age population is participating in the labour market
9	Employment-to-Population Ratio	Employed ÷ Working-Age Population × 100	How much of the working-age population is actually employed
10	Dependency Ratio	Dependants ÷ Working-Age Population × 100	The demographic load carried by the working-age population

PART II — POPULATION AS AN ECONOMIC SYSTEM LOAD

These are particularly important for the STRLDi National Economic Operating System.

#	Concept	Formula the team must determine	What it must reveal
11	Population Growth Rate	Full demographic growth formula	How quickly the population stock is changing
12	Compound Population Projection	$P_t=P_0(1+g)^t$	The future population load if the growth assumption persists
13	Migration Stress Load	Base Population × Migration Stress %	Additional population load under the defined scenario
14	Total Planning Population	Projected Resident Population + Migration Stress Load	The population capacity the system must be designed to absorb
15	Household Formation Rate	Households ÷ Population, with appropriate household-size formulation	The number of household nodes the economy must support
16	Working-Age Population Projection	Projected population × working-age share	Future labour-system load
17	Labour-Force Projection	Working-Age Population × participation rate	Future labour supply
18	Employment Requirement	Labour Force × target employment rate	Number of people the productive system must absorb

STRLDi application

The team must demonstrate how:

Population → Households → Working-age population → Labour force → Employment requirement

changes over 5, 10 and 20 years.

PART III — PRODUCTIVE CAPACITY

These concepts move the team from counting people to determining what the economy can actually do with them.

#	Concept	Formula to determine	Economic use
19	Productive Capacity	Define the appropriate physical/economic capacity formulation	Determines the maximum sustainable output the system can generate
20	Capacity Utilisation	Actual Output ÷ Productive Capacity × 100	Shows how much existing capacity is being used
21	Output per Worker	Total Output ÷ Workers	Measures worker-level production
22	Capital per Worker	Capital Stock ÷ Workers	Measures capital intensity
23	Capital Productivity	Output ÷ Capital Input	Shows output generated by capital
24	Land Productivity	Output/Value ÷ Land Area	Measures productive use of land
25	Water Productivity	Economic Value ÷ Water Used	Measures economic value generated from water
26	Energy Productivity	Economic Output ÷ Energy Consumed	Measures output generated per unit of energy

The team must distinguish carefully between:

Employment capacity

and

productive capacity.

They are not the same thing.

PART IV — ENTERPRISE AND ORGANISATIONAL CAPACITY

The STRLDi architecture treats organisations as the nodes through which people become economically productive.

#	Concept	Formula to determine	Economic use
27	Enterprise Density	Number of Enterprises ÷ Population	Measures organisational capacity relative to population
28	Workers per Enterprise	Total Workers ÷ Number of Enterprises	Determines average employment scale

32	Enterprise Productivity	Enterprise Output/GVA ÷ Workers	Compares productivity across enterprise types
33	Economic Density	Determine an appropriate STRLDi formulation	Measures concentration of productive organisations, infrastructure, capability and flows

The team should specifically examine how many enterprises are required to absorb a given population under different assumptions about average enterprise size and productivity.

PART V — DEMAND AND SUPPLY

The pipeline cannot be sized without understanding demand.

#	Concept	Formula to determine	Economic use
34	Demand Gap	Required Demand − Available Supply/Capacity	Quantifies unmet market demand
35	Supply Gap	Required Output − Existing Productive Capacity	Identifies capacity that must be constructed
36	Market Share	Firm/Sector Sales ÷ Total Market Sales × 100	Measures position within a market
37	Demand Growth Rate	Change in Demand ÷ Previous Demand × 100	Determines how rapidly the market is changing
38	Price Elasticity of Demand	% Change in Quantity Demanded ÷ % Change in Price	Shows how demand responds to price
39	Price Elasticity of Supply	% Change in Quantity Supplied ÷ % Change in Price	Shows how production responds to price
40	Domestic Market Size	Relevant population × consumption/use per person	Establishes potential domestic demand
41	Export Market Potential	Market demand × attainable market share	Estimates potential external demand

Required application

Use the STRLDi example:

National tomato demand = 20,000 tonnes

Current/local capacity = 14,000 tonnes

The team must calculate and explain the 6,000-tonne capacity/demand gap and identify what additional information is required before a national investment decision could be made.

PART VI — VALUE CHAINS AND VALUE ADDITION

56	Average Wage	Total Wage Bill ÷ Number of Employees	Measures average labour income
57	Real Wage	Nominal Wage adjusted by price index	Shows actual purchasing-power movement
58	Real Wage Growth	Change in Real Wage ÷ Previous Real Wage × 100	Shows whether household purchasing power is improving
59	Wage Share of GDP/GVA	Total Compensation of Employees ÷ GDP/GVA × 100	Shows how much economic value flows to labour
60	Household Income per Capita	Total Household Income ÷ Population	Measures average household income
61	GDP per Worker vs Wage	GDP/GVA per Worker compared with Average Wage	Shows the relationship between productivity and labour income

The team must understand why:

higher employment ≠ automatically higher household income

and why:

higher productivity creates the potential for higher wages.

These calculations are particularly important for the four-country composite comparison used in the Scenario B analysis.

PART XIII — SYSTEM PRODUCTIVITY

The following concepts require particular attention because they move STRLDi beyond conventional economic measurement.

94	Reinvestment Rate	Reinvestment ÷ Profit/Available Surplus × 100	Measures how much surplus returns to productive capacity
95	Domestic Value Retention	Value retained domestically ÷ Total economic value × 100	Measures how much value remains in the national system
96	Enterprise Absorption Ratio	Employment generated by private enterprises ÷ Required employment × 100	Measures private-sector capacity to absorb the population

Important: For the STRLDi-specific measures—particularly EIP, Population Absorption Capacity, Pipeline Throughput and Domestic Value Retention—the team must first identify the precise formulation being used in the STRLDi work. Do not invent a formula merely because a conventional economic formula looks similar.

STRLDi ECONOMIC SYSTEMS LEARNING SERIES

ASSIGNMENT 22: DERIVING THE KEY ECONOMIC FORMULAS

Purpose

This assignment is designed to develop the team’s ability to read the economy through numbers.

The objective is not to memorise economic formulas. Each participant must understand what a number represents, how it is derived, what other numbers it is connected to, and what the resulting relationship tells us about the functioning—or failure—of the economic system.

The assignment progresses from relatively simple calculations into the more demanding relationships required for STRLDi’s work on population, productive capacity, enterprise formation, the goods pipeline, the money pipeline, and national economic transformation.

A NOTE BEFORE YOU BEGIN

Mathematics is one of the few subjects that cannot get away with being close to the right answer. It has to be the right answer. This is a tough place to be for the smooth or slick talker. But the irony is that, as we learn to get closer to the right answer, our minds—and not our tongues—are getting sharper. It is the sharpness that we need to slice through the tough moments of our lives.

So, while learning, do not be afraid to get things wrong. Every wrong turn is turning us towards the right one. There is no glory in being right when we do not understand. We hope these exercises shape that understanding for you.

The purpose is not simply to get the answer right. The purpose is to understand why it is right.

ASSIGNMENT STRUCTURE

The assignment consists of six learning blocks and 30 economic concepts.

The concepts are deliberately sequenced. Do not jump ahead simply because a later formula appears more interesting. The purpose is to develop the mathematical reasoning progressively.

BLOCK 1 — SEE THE POPULATION

Concepts 1–5

No.	Concept	Formula / Relationship
1	Percentage Change / Growth Rate	$(New-Old) / Old × 100$
2	Population Growth	$P_t=P_0(1+g)^t$
3	Labour Force Participation Rate	Labour Force ÷ Working-age Population × 100
4	Employment / Unemployment Rate	Unemployed ÷ Labour Force × 100
5	Dependency Ratio	Dependants ÷ Working-age Population × 100

Assignment 1 — Establish the Population Load

For each concept:

Write the formula in full.
Define every variable.
State the unit of measurement.
Explain what the formula measures.
Explain why the measure matters to STRLDi.
Apply it to Botswana using an identified data source.
Show the complete calculation.
Interpret the result.
Identify what the number does not tell us.

Systems Question

If the population increases but productive capacity does not increase at the same rate, what happens to the economic system?

BLOCK 2 — SEE PRODUCTIVITY

Concepts 6–12

No.	Concept	Formula / Relationship
6	GDP	Total value of final goods and services
7	GDP per Capita	GDP ÷ Population
8	GDP per Worker / Labour Productivity	GDP ÷ Workers
9	Output per Worker Growth	Change in GDP/worker over time
10	Wage / Productivity Relationship	Labour Income ÷ Workers, compared with GDP/worker
11	Sectoral Employment Share	Sector Workers ÷ Total Workers × 100
12	Sectoral Value Added / Worker	Sector GVA ÷ Sector Workers

Assignment 2 — Move from People to Productive Capacity

The team must demonstrate mathematically why:

A person employed is not necessarily a person generating sufficient productive value for the economic system.

Calculate and compare:

GDP per capita;
GDP per worker;
GDP per worker by sector;
employment share by sector;
value added per worker by sector;
average wage/worker where reliable data exists.

Systems Question

What happens to national income when employment increases but output per worker remains approximately unchanged?

Then apply the reasoning to Scenario A and Scenario B.

BLOCK 3 — SEE THE ORGANISATIONS

Concepts 13–16

No.	Concept	Formula / Relationship
13	Enterprise Density	Enterprises ÷ Population / Workers
14	Enterprise Employment Capacity	Workers ÷ Enterprises
15	Capital per Worker	Capital Stock ÷ Workers
16	Capital Productivity	Output ÷ Capital

Assignment 3 — Size the Organisation Nodes

Using the Scenario B planning population:

Determine the population load.
Determine the required working population.
Determine the required private employment population.
Determine the number of enterprises required under the assumptions provided.
Determine the implied average employment capacity per enterprise.
Calculate capital required per worker where data and assumptions permit.
Compare capital productivity between the relevant scenarios or sectors.

Systems Question

If people are the load entering the economic system, what organisations must exist to receive them?

The team must distinguish between:

People → Organisations → Productive Capacity

and

People → Jobs

These are not the same system.

BLOCK 4 — SEE THE MONEY

Concepts 17–20

No.	Concept	Formula / Relationship
17	Investment Rate	Gross Investment ÷ GDP × 100
18	Return on Investment (ROI)	Return ÷ Investment × 100
19	Hurdle Rate	Required return compared with investment return
20	Economic Investment Productivity (EIP)	Output ÷ Investment

Assignment 4 — Determine Whether the Pipeline Can Finance Itself

The team must:

Define investment.
Distinguish investment from expenditure.
Calculate an investment rate.
Calculate ROI.
Explain the meaning of a hurdle rate.
Explain why a private investor will compare expected return with a hurdle rate.
Calculate EIP.
Examine the Scenario A and Scenario B EIP assumptions.
Explain what a higher EIP means for national transformation.
Identify the relationship between investment → productive capacity → output → return → reinvestment.

Systems Question

What happens to a production system when the money generated by production does not return sufficiently to finance the next cycle of production?

BLOCK 5 — SEE THE GOODS

Concepts 21–24

No.	Concept	Formula / Relationship
21	Input–Output / Value-Chain Relationship	Inputs → Transformation → Output
22	Demand–Supply Gap	Demand − Available Capacity
23	Capacity Utilisation	Actual Output ÷ Potential Output × 100
24	Production Capacity Required	Contracted Demand ÷ Expected Yield/Productivity

Assignment 5 — Build the Demand-to-Production Calculation

Use the STRLDi example:

Demand = 20,000 tonnes
Existing capacity = 14,000 tonnes
Production gap = 6,000 tonnes
Contracted production window = 12 weeks

The team must determine:

The demand gap.
The percentage of demand currently covered.
The percentage capacity deficit.
The required additional production.
The required weekly production within the 12-week window.
The productive capacity required to close the gap.
What information would be required before a production contract could responsibly be issued.

Then map the relationship:

Demand → Demand Definer → Corridor Operator → SOUs → Production → Aggregation → Quality → Processing → Logistics → Buyer

Systems Question

Why is the 6,000-tonne gap not simply a problem for farmers?

The answer must identify the organisational, financial, infrastructural, technical and commercial requirements behind the additional capacity.

BLOCK 6 — SEE THE NATIONAL SYSTEM

Concepts 25–30

No.	Concept	Formula / Relationship
25	Compound Reinvestment / Capacity Growth	$K_t=K_0(1+r)^t$
26	Multiplier Effects	Initial Change × Multiplier
27	Trade Balance / Import Dependence	Exports − Imports
28	Export Intensity	Exports ÷ Output × 100
29	Fiscal Revenue / Tax-to-GDP	Tax Revenue ÷ GDP × 100
30	Required Productive Capacity per Population	Required Output ÷ Planning Population

Assignment 6 — See the Whole System

The final assignment must bring the preceding five blocks together.

The team must demonstrate the chain:

Population → Labour → Productivity → Organisations → Investment → Production → Demand → Goods Flow → Revenue → Reinvestment → Expanded Capacity

For each stage, identify:

the input number;
the formula;
the output number;
the unit;
the economic meaning;
the next relationship in the system.

FINAL INTEGRATION EXERCISE

From Population to Production

Using the Scenario B framework, construct a numerical model showing how the system moves from the planning population to productive capacity.

Your model must include, at minimum:

System Layer	Number Required
Planning population	Calculate
Working-age population	Calculate
Labour force	Calculate
Employment requirement	Calculate
Public employment	Calculate
Private employment	Calculate
Agricultural employment	Calculate
Manufacturing employment	Calculate
Services employment	Calculate
Required enterprises	Calculate
Required workers per enterprise	Calculate
Required production capacity	Calculate
Demand gap	Calculate
Investment requirement	Calculate
Expected output	Calculate
GDP per worker	Calculate
Expected household income	Calculate
ROI	Calculate
EIP	Calculate
Reinvestment capacity	Calculate

Then answer the central STRLDi question:

What must be built today so that the population arriving in 5, 10 and 20 years can enter an economy that is capable of absorbing them productively?

RULES FOR THE ASSIGNMENT

1. No unexplained numbers

Every number must have a source, an assumption, or a derivation.

2. No formula without variables

Writing a formula without explaining what each component means is incomplete.

3. No answer without units

Pula, tonnes, people, workers, enterprises, percentages and years are not interchangeable.

4. No rounding until the appropriate stage

Do the calculation first. Round only when presenting the final result, and state the rounding.

5. Distinguish fact from assumption

The team must clearly mark:

Observed Data | Assumption | Derived Number | Scenario Number

6. Show the calculation

A final answer such as P776,000 is not sufficient. The team must show how it was obtained.

7. Test the answer

Ask:

Does the number make sense in relation to the other numbers in the system?

8. Do not hide an error

If the result is wrong, identify where the calculation went wrong, correct it, and explain the correction.

FINAL TEAM OUTPUT

At the completion of the six blocks, each team should be able to produce a STRLDi Economic Formula Book containing:

30 formulas and relationships
Definitions of all variables
Units of measurement
Botswana applications
Sources for all external data
Assumptions used
Complete calculations
Interpretation of every result
Scenario A calculations
Scenario B calculations
Comparison of the two trajectories
A final integrated Population-to-Production numerical model

The ultimate test is not whether the team can repeat an economic term.

It is whether, when presented with a number, the team can ask:

Where did this number come from? What does it mean? What does it cause? What does it require elsewhere in the system? And what happens if it changes?

That is the beginning of economic systems thinking.

THE FINAL TEAM TEST

After completing the formulas, the team must take one Botswana economic problem—persistent unemployment—and connect at least 15 of the formulas into one numerical chain.

The chain should demonstrate:

Population

→ Working-Age Population

→ Labour Force

→ Unemployment

→ Required Employment

→ Enterprise Capacity

→ Productive Capacity

→ Demand

→ Demand/Capacity Gap

→ GVA

→ GVA per Worker

→ Wages

→ Investment

→ ROI

→ Reinvestment

→ Expanded Productive Capacity

→ Next Population Increment

The question the team must ultimately answer:

Can we use these numbers to see why unemployment persists—or are we merely measuring the consequences after the system has already produced them?

That is the distinction STRLDi members need to master.
