Demand-Activities Worksheet
Key terms:
Demand - the quantity of goods and services that consumers are willing and able to
purchase at a given time, at a given price, ceteris paribus.
Ceteris paribus - means that all other variables remain the same.
Income effect – the effect of a change in the price of a good or service on real incomes.
As the price of a good or service falls, then the real income levels of consumers rise. This
means that consumers will be able to purchase more good and services than they were
before and quantity demanded for the product will rise - HL only.
Substitution effect – the effect of a change in the price of a good or service on the
relative price of the product. As a product falls in price then the good will be relatively
cheap, compared to its substitutes and so some consumers will switch their demand to the
good raising demand - HL only.
