Price Determination in a Competitive Market Flashcards
Equilibrium Price
The price at which planned demand for a good or service exactly equals planned supply
Supply
The quantity of a good or service that firms are willing and able to sell at given prices in a given period of time
Demand
The quantity of a good or service that consumers are willing to buy at given prices in a given period of time
Effective Demand
The desire for a good or service backed by an ability to pay
Market Demand
The quantity of a good or service that all the consumers in a market are willing and able to buy at different market prices
Condition of Demand
A determinant (or factor) of demand: other than the good’s own price, that fixes the position of the demand curve
What are the factors of demand?
Population, Advertising, Substitute Goods, Income, Fashion, Interest Rates and Complimentary Goods
What shows an increase in demand?
A rightward shift of the demand curve
What shows a decrease in demand?
A leftward shift of the demand curve
Normal Good
A good for which demand increases as income rises and demand decreases as income falls
Inferior Good
A good for which demand decreases as income rises and demand rises as incomes fall
Elasticity
The proportionate responsiveness of a second variable to an initial change in the first
Price Elasticity of Demand
Measures the extent to which the demand for a good changes in response to a change in the price of that good
The steeper the graph, the ________ the Demand.
More inelastic
The shallower the graph, the _________ the Demand.
More elastic
What is is the demand price elasticity of a good/service which is inelastic?
-1
What is is the demand price elasticity of a good/service which is elastic?
-1>
Income elasticity of demand
measure the extent to which the demand for a good changes in response to a change in income.
Income elasticity of Demand (Formula)
Percentage change in quantity demanded/Percentage change in income
Cross elasticity of Demand
Measure the extent to which the demand for one good changes in response to a change in the price of another good
Cross elasticity of demand (Formula)
Percentage change in quantity demanded of X/Percentage change in the price of Y
