Topic 2 Flashcards
What is a competitive market?
One which has many buyers and sellers and no single buyer or seller can influence the price. The producers offer items for sale only if the price is high enough to cover their opportunity cost.
What is money price?
The no. of £’s that must be given up in exchange for a good/service.
What is relative price?
The ratio of one price to another (opportunity cost).
What is the quantity demanded of a good?
The quantity demanded of a good is the amount that consumers plan to buy during a particular time period at a particular price. This isn’t always the quantity actually bought, as sometimes the quantity demanded is greater than the no. of available goods so therefore the quantity bought is less than the quantity demanded.
What does the law of demand state?
When other factors stay the same, the higher the price of a good, the smaller is the quantity demanded.
= downwards sloping demand curve.
What is the substitution effect?
When the price of a good rises, other things remaining the same, it’s relative price (opportunity cost) rises. As this increases, the desire to economise and switch to a cheaper alternative becomes stronger.
What is the income effect?
As the price of a good falls (rises) a consumers real income rises (falls), allowing the consumer to buy more (less) units of all goods.
What is demand?
Demand refers to the relationship between the price of a good and the quantity demanded of that good.
What does a demand curve show?
The relationship between the quantity demanded of a good, and its price, when all other factors remain the same. (x = quantity demanded, y = price).
What is a demand schedule?
It lists the quantities demanded at each price, when all the other influencing factors remain the same.
What causes a change in demand?
When any factor that influences buying plans changes, other than the price of a good, the demand changes.
What happens when demand rises?
The demand curve shifts to the right and the quantity demanded at each price is greater.
What is a measure of marginal benefit?
The willingness and ability to pay.
What factors bring a change in demand?
1 = Prices of relative goods. 2 = Expected future prices 3 = Income 4 = Expected future incomes + credit 5 = Population 6 = Preferences
How does the prices of related goods affect demand?
A good substitute is a good that can be used in place of another, if a substitute is cheaper then consumers will buy more of the alternative.
What is a complement good?
A good that is used in conjunction with another good.
How do expected future prices affect demand?
If the expected price of a good rises for the future, and the good can be stored then the opportunity cost of getting the good now is lower today than it will be in the future.
How does income affect demand?
When income increases consumers buy more of most goods, and when income decreases they buy less.
Normal good = increasing income, increasing demand
Inferior good = increasing income, decreasing demand
How do expected future incomes and credit affect demand?
When expected future income increases or credit becomes easier to obtain, demand for a good might increase.
