Unit 1 - Demand, Supply and Markets Flashcards
What is demand?
Demand is the quantity of a good or service that consumers are willing to buy at a given price in a given time period.
What is effective demand?
the actual quantity of a good or service that consumers are willing and able to buy at a particular price in a certain period of time.
Know how to draw demand curves from demand schedules.
Use notes and jotter.
Why is the demand curve downward sloping?
-The law of diminishing marginal utility
-The substitution effect
-The income effect
What is the substitution effect?
The substitution effect is when a consumer consumes more of another product because of a price rise.
The substitution effect is the decrease in sales for a product that can be attributed to consumers switching to cheaper alternatives when its price rise
What is utility?
Utility is the satisfaction that someone gains from consuming a good or service.
What is total utility?
This is the total satisfaction you get from consuming a certain number of units of a good or service.
What is marginal utility?
Marginal utility is the extra satisfaction gained from consuming consecutive units of a good or service.
What is diminishing marginal utility?
Diminishing Marginal utility is the diminishing satisfaction gained from consuming consecutive units of a good or service. (the more of an item that you use or consume, the less satisfaction you get from each additional unit consumed or used.)
Be able to draw/use demand diagrams to explain how changes in the determinants of demand affect price and quantity demanded
Look at notes and at jotter.
What is a substitute good or service?
goods and services that are similar. For example, if the price of one chocolate rose then the demand for another brand, that has not risen in price will increase.
What is a complementary good or service?
one that goes along with another good or service. For example, strawberries and cream, if the price of strawberries fell then the demand for cream would increase.
What does it mean if the demand curve shifts outwards?
this means that at all prices consumers demand more of a good or a service. (Shift right)
What does it mean if the demand curve shifts inwards?
this means that at all prices consumers demand less of a good or a service (Shift left)
What does the income effect describe?
how changes to consumers real income level can affect their purchasing patterns.
