Scarcity

A

results from the fact that people have unlimited wants but resources to meet these wants are limited. In essence, people would like to consume more goods and services than the economy is able to produce with its limited resources

Q

productive efficiency

A

For the economy as a whole occurs when it is impossible to produce more of one good without producing less of another. For a firm it occurs when the average total cost of production is minimised.

Q

allocative efficiency

A

occurs when the available economic resources are used to produce the combination of goods and services that best matches people’s tastes and preferences (producing the things people most want)// occurs when it is impossible to improve overall economic welfare by reallocating resources between markets.

Q

market equilibrium

A

a market is in equilibrium when planned demand equals planned supply and the demand curve crosses the supply curve. In this situation there is no excess demand or excess supply in the market. Unless some event disturbs the equilibrium, there is no reason for the price to change.

Q

market disequilibruim

A

exists at any other price other than the equilibrium price. When the market is in disequilibrium, either excess demand or excess supply exists in the market. Excess demand causes the price to rise until a new equilibrium is established. Conversely, excess supply causes the market price to fall until equilibrium is achieved.

a strategic or man-made barrier to entry caused by government legislation protecting the right of a firm to be the sole producer of a patented good, unless the firm grants royalties for other firms to produce the good

111
Q

natural barrier to entry

A

a barrier to market entry which is not man-made// barriers to market entry caused by geography. For example, if one firm has control of a resource essential for a certain industry, other firms are unable to compete in a industry

informative advertising

Q

persuasive advertising

attempts to persuade potential customers that a good or service possesses desirable characteristics that make it worth buying

Q

saturation advertising

A

through flooding the market with information and persuasion about a firm’s product, this functions as a man-made barrier to market entry by making it difficult for smaller firms to compete.

116
Q

product differentiation

making a product different from other products through product design, the method of producing the product, or through its functionality// the marketing of generally similar products with minor variations or the marketing of a range of different products

117
Q

quantity setter

A

a firm chooses the quantity of a good to sell, rather than its price. In monopoly, the market demand curve then dictates the maximum price that can be charged if the firm is to successfully sell its chosen quantity.
