LEARNING OUTCOMES

(a) Identify the equilibrium price in a product or factor markets likely to result

from specified changes in conditions of demand or supply.

THE DEFINITION OF A MARKET

and does not necessarily refer to a

physical location, but instead a place whereby potential buyers and sellers meet for

the purposes of exchanging goods / services.

Examples include:

Type of market Goods / services exchanged

Product market

Commodity market

Financial market

Factor market

Note: This chapter focuses upon product markets, the term goods is used to

denote the provision of tangible goods and intangible services.

THE DEMAND CURVE

Demand for a good is the quantity of that good that potential purchasers would be

willing and able to buy, at a given price.

The law of demand states that as the price of a good falls, ceteris paribus, the

quantity demanded will increase.

Graphical representation

Changes in demand

Examination questions will typically require students to interpret the impact on

demand following changes to price and the conditions of demand. Changes may

affect the demand curve in one of two ways:

(i) Movement along the demand curve (extensions/contractions)

(ii) Shift of the demand curve.

A movement along the demand curve occurs when a change in the price of a

product leads to a change in the quantity demanded, as shown below:

A shift to the right in the demand curve arises when at every price consumers are

willing and able to buy more than they did before, as shown below:

Conversely a shift to the left would arise if consumers are able and willing to buy

less than they did before at each available price.

Shifts in the demand curve arise when the conditions of demand, as previously

discussed, change.

THE SUPPLY CURVE

Supply refers to the quantity of a good that existing suppliers, or would be

suppliers, are willing and able to produce for the market at a given price.

The law of supply states that as prices rise, ceteris paribus, the quantity supplied

of the good will increase.

Graphical representation

Market supply

The total quantity of a product that all producers, existing and potential, would

want to supply at each price.

Determinants of supply (excluding price)

1. Cost to produce

2. Price of substitute goods

3. Price of complements

4. Technology

5. Other factors

Changes in supply

Understanding the effect of changing prices / conditions of supply on the supply

curve are key learning points for the exam.

A movement along the supply curve occurs following a change in the price of a

product which leads to a change in the quantity supplied, as shown below:

Shifts in the supply curve arise when the conditions of supply change (other than

the price of the good itself!)

A reduction in the cost of supply will cause the supply curve to shift right, an

increase in the cost of supply will cause the supply curve to shift to the left.

FORMATION OF EQUILIBRIUM PRICE

Market price is determined by the interaction of demand and supply. The

equilibrium price being where demand equals supply.

Functions of the price mechanism

There are three functions of the price mechanism, as follows:

1. Signalling

2. Rationing

3. Rewarding

Discussion 2

Discuss the likely implications of price falling below P1 in the context of the three

functions of the price mechanism.

1. Signalling;

2. Rationing;

3. Rewarding.
