Below is a structured, student-friendly explanation of the topics you listed, using Papua New Guinea (PNG) examples where relevant. I follow the SBC Strand One focus on Foundations of Business and tie each concept back to how it affects businesses, households and the wider economy in PNG.
1) What is an economic system (brief)
- An economic system is the way a society organizes production, distribution and consumption of goods and services. It answers: What to produce? How to produce? For whom to produce?
- Economic systems differ by who makes decisions (households, markets, government, or tradition) and by how resources (land, labour, capital) are owned and used.
2) Development of economic systems in PNG societies
- Pre-contact / Traditional economy:
- Most PNG societies were (and many still are) organized around subsistence agriculture, hunting, fishing and local exchange. People produced mainly for their own families or immediate community. Custom, clan leadership and reciprocity governed economic life.
- Barter and gift exchange (payback, bride price customs) were important. Land and resources were managed according to customary rules.
- Colonial period:
- European colonisation introduced a cash economy, plantations (copra, cocoa, coffee), wage labour, taxation and formal trade in ports and towns.
- Roads, ports and export crops linked parts of PNG to global markets.
- Post-independence and modern development:
- PNG’s economy became more mixed: a large subsistence rural sector remained alongside a formal cash sector based on mining, petroleum, agriculture export crops and services.
- Mining and petroleum projects brought rapid inflows of foreign exchange, investment and urban employment but also revealed challenges: land rights, environmental impact and uneven regional development.
- Contemporary trends:
- Urbanisation, growth of services, expansion of small businesses, greater use of formal banking and mobile money, but continued importance of customary land and the subsistence sector.
- PNG is essentially a dual economy: modern/commercial sector and traditional/subsistence sector coexist.
3) Features of different economic systems (and PNG examples)
- Traditional (customary) economy
- Features: production for use not profit, strong role for customs and kinship, barter and gift exchange, communal land/ resource rights.
- PNG example: many villages with subsistence gardening, sharing food through customary obligations.
- Command (planned) economy
- Features: government owns/controls major resources and decides production and prices; central planning replaces market signals.
- PNG example: not typical in PNG nationally, though governments sometimes control key services or state-owned enterprises (utilities, airlines, mining stakes).
- Market economy (pure)
- Features: private ownership, prices determined by supply and demand, minimal government intervention, competition drives allocation.
- PNG example: some urban markets and private enterprises operate this way, but no pure market economy exists.
- Mixed economy
- Features: mixture of private markets and government intervention/ownership; government provides public goods and regulation.
- PNG example: PNG operates as a mixed economy—private businesses and markets exist alongside government ownership of some firms, regulations, social services and public infrastructure projects.
4) Key features of the PNG economy
- Dual nature: large subsistence rural economy and a modern cash economy (mining, petroleum, agriculture, services) coexist.
- Resource dependence: exports dominated by minerals, oil/gas, timber and agricultural cash crops (coffee, cocoa, palm oil). Commodities strongly influence national income and foreign exchange.
- Customary land tenure: about 97%+ of land is customary; this shapes investment, land use and ownership patterns.
- Large informal sector: many small traders, market vendors, informal transport and family enterprises.
- Limited infrastructure and high transport costs: geography (mountains, islands) raises costs and limits market access.
- Vulnerability: exposure to world commodity price swings, natural disasters, and environmental risks from resource projects.
- Human development challenges: uneven access to education, health, and employment opportunities; urban migration pressures.
- Growing financial services and mobile money but still low financial inclusion in some rural areas.
5) Role of government in an economic system (general and in PNG)
- Provide public goods and services: roads, ports, schools, health facilities, security and law and order.
- Regulation and legal framework: enforce contracts, property rights (including managing dealings on customary land), consumer protections, environmental regulation.
- Stabilisation and macro policy: central bank (Bank of Papua New Guinea) conducts monetary policy (currency stability, inflation control) and the government uses fiscal policy (taxes, spending) to influence the economy.
- Redistribution and social policy: taxation, subsidies, social programs to reduce poverty and invest in human capital.
- Direct provision and ownership: government owns or part-owns state-owned enterprises (utilities, airlines, oil/gas stakes) and may intervene to protect strategic sectors.
- Development planning and investment promotion: attract investment, manage resource revenues, negotiate landowner benefits, and invest in infrastructure.
- Regulation of markets: competition policy, price controls when needed, licensing and standards.
- In PNG specific context: government plays a key role in resource revenue management, negotiating with multinational extractive companies, providing royalties/benefit-sharing to customary landowners, and funding public services in remote areas.
6) Exchange of money in an economic system (functions of money and how exchange works)
- Functions of money:
- Medium of exchange: replaces barter and makes transactions easier (useful in markets and business).
- Unit of account: prices and accounting use a common measure (Kina in PNG), simplifying comparison of value.
- Store of value: money allows saving for future purchases (but inflation can erode value).
- Standard of deferred payment: money is used to settle debts and loans.
- How money exchange works in PNG:
- Formal sector: Kina (PGK) is used in shops, banks and formal transactions. Banks and microfinance provide deposit, credit and payment services.
- Central bank role: Bank of Papua New Guinea issues currency, sets monetary policy, and supervises banks.
- Informal and cash transactions: many rural and small transactions are still cash-based or rely on informal credit, barter or reciprocal arrangements.
- Mobile money and fintech: growing use of mobile payment systems (e.g., telco-based services) to transfer money, pay bills and increase financial inclusion—useful in remote areas where banks are scarce.
- Importance for business:
- Efficient money exchange lowers transaction costs, supports trade, investment and growth.
- Access to banking affects the ability of small firms to save, borrow and expand.
7) Basic features of a market economy
- Private property rights: individuals and firms can own and use resources.
- Voluntary exchange: buyers and sellers freely trade in markets they choose.
- Price mechanism: prices adjust according to supply and demand and coordinate decisions.
- Competition: firms compete for customers, encouraging efficiency and innovation.
- Profit motive and entrepreneurship: firms seek profits, which drives production and new business creation.
- Consumer sovereignty: consumers’ choices guide what is produced.
- Limited but important government role: protecting property rights, enforcing contracts, providing public goods and regulating market failures.
- Decentralised decision-making: many participants (households and firms) make decisions, not a central planner.
8) Role of market and price in the economy
- Allocate scarce resources: markets channel labour, capital and materials to uses where they are most valued based on ability and willingness to pay.
- Provide information: prices convey signals about scarcity and consumer preferences—high price signals scarcity or strong demand; low price signals abundance or weak demand.
- Provide incentives: higher prices motivate producers to supply more; lower prices discourage production and encourage consumption.
- Rationing function: price limits who can buy a good when supply is limited.
- Coordinate economic activity: prices help coordinate many buyers and sellers without central planning.
- Encourage innovation and efficiency: competitive pressure and price signals push firms to reduce cost and innovate.
- PNG examples:
- Coffee or cocoa prices on the world market affect how much farmers plant and sell.
- High transport costs raise local prices for imported goods, affecting affordability and business margins.
9) Role of the law of demand and supply in the economy
- Law of Demand:
- Definition: ceteris paribus (all else equal), when price of a good rises, quantity demanded falls; when price falls, quantity demanded rises.
- Factors affecting demand: income, tastes, prices of related goods (substitutes/complements), population, expectations.
- PNG example: if the price of imported rice increases, consumers may buy less rice or switch to local staples like sweet potato (kaukau).
- Law of Supply:
- Definition: ceteris paribus, when price rises, quantity supplied rises; when price falls, quantity supplied falls.
- Factors affecting supply: production costs, technology, number of sellers, expectations, weather conditions.
- PNG example: a rise in world gold prices may lead mining firms to increase extraction; a drought may reduce supply of fresh produce and push up prices.
- Market equilibrium:
- Where supply equals demand determines equilibrium price and quantity.
- If price is above equilibrium (surplus), sellers reduce price; if price is below equilibrium (shortage), price tends to rise.
- Shifts vs movements:
- Movement along curves: caused by price changes.
- Shifts of curves: caused by non-price factors (income, tastes, input costs, technology).
- Government intervention effects:
- Price ceilings (maximum prices) can cause shortages—example: setting low prices for essential goods might lead to scarcity if producers won’t supply at that price.
- Price floors (minimum prices) can create surpluses—example: minimum wage can create labour supply–demand adjustments.
- Practical consequences for PNG:
- Export commodity price swings affect incomes of producers and government revenue—when demand for PNG’s exports rises, prices and incomes increase; when demand falls, incomes drop.
- Seasonal supply fluctuations (vegetables, fish) produce price volatility in local markets—important for household food security and incomes of small producers.
10) Classroom/Business implications and summary points
- For students: Understanding these concepts helps explain why businesses make certain choices (where to invest, what to produce), why prices change and how government decisions affect markets.
- For PNG: the mixed, dual economy with heavy reliance on natural resources and customary land arrangements creates special development challenges (infrastructure needs, equitable sharing of resource benefits, diversification away from commodity dependence).
- Policymakers and businesses must consider market signals, the limits of markets (externalities, public goods), and the government’s role in stabilising and supporting inclusive growth.
If you want, I can:
- Create a one-page summary sheet for students.
- Provide PNG-specific case studies (e.g., coffee price shocks, a mining project impact, or a village market example).
- Make multiple-choice or short-answer questions for revision.
