A decision you can investigate
- A specialist repairer cannot live only on repairs. The repairer needs food, housing and transport supplied by other people.
- Specialization requires a way to exchange output and finance activity.
Build the explanation
- Division of labour splits production into specialized tasks. Repetition can develop skill, reduce switching time and support specialized tools; coordination, boredom and dependency can be costs. Adam Smith emphasized these mechanisms in his account of specialization.
- Money is a medium of exchange 交换媒介, measure of value, store of value and standard of deferred payment. It avoids the need for a double coincidence of wants under barter. Financial markets help people save, obtain funds, make transactions, agree future commodity/currency exchange and trade equity ownership.
Work through the evidence
- A repairer earns 600 yuan and spends 300 on food, 100 on transport and saves 200. Money connects separate suppliers without requiring each to need a repair. A business can finance equipment by borrowing or issuing equity; equity gives an ownership claim rather than a fixed-interest loan.
- A fictional importer agrees now to buy 1000 dollars in three months at 7 yuan per dollar. The forward agreement fixes 7000 yuan of currency cost. If the later spot rate is 8, the agreement avoids an 8000-yuan spot cost; if it is 6, it forgoes a cheaper 6000-yuan spot purchase.
What currency cost does the fictional forward fix?
1000 dollars × 7 yuan per dollar = 7000 yuan.
Test the limits
- A forward hedges a stated exposure; it does not guarantee an overall profit. Counterparty risk and contract terms still matter. Saving does not instantly become productive investment in every case.
- Money’s store-of-value function can weaken under inflation. Equity returns are uncertain and ownership can be diluted. Specialization benefits depend on demand, quality and coordination. Smith’s original pin-making discussion is in The Wealth of Nations, Book I, Chapter I. Read its task/skill/time-saving argument, not an unsupported claim that all modern production has the same gains.
Which distinguishes equity from a loan?
An equity holder owns a share; a lender holds a debt claim.
A forward agreement guarantees that its buyer obtains the cheapest eventual exchange rate.
It fixes a rate; a later spot rate may turn out more favourable.
Apply and explain your answer
- Why can the forward agreement help planning even if the later spot rate is cheaper?
- It fixes the currency cost in advance, exchanging possible savings for reduced uncertainty.
Which problem does money reduce compared with barter?
A common payment medium removes the double coincidence requirement.
Use the terms precisely
- medium of exchange: An accepted means of paying for goods and services.
- forward contract 远期合约: An agreement now for an exchange at specified terms on a future date.
Match the terms to their meanings.
Use each term for its stated economic relationship.
