Economics Flashcards
When the prices of an item increases supply increases- because more sellers are willing to sell.
Economics
When supply changes due to something other than price.
Economics
Supply increases at each price point
Higher Equilibrium GDP
Number of sellers increases - market can get flooded
Examples: Government subsidies or technology improvements that decrease costs for suppliers
Economics
Supply decreases at each price point
Lower Equilibrium GDP
Cost of producing item increases
Examples: Shortage of gold- so less gold watches are made; wars or crises in rice-producing countries means there is less rice on the market
Economics
When the prices of an item increases- demand for it decreases.
Economics
When demand changes due to something other than price.
Economics
When demand increases at each price point
Price of substitutes go up - price of beef rises- so people buy more chicken
Future price increase is expected - War in Middle East- people go out and buy gas
Market expands - i.e. people get new free health care plan- demand at clinic rises
Expansion - more spending increases equilibrium GDP
Economics
Demand decreases at each price point.
Price of complement goes up - price of beef goes up- less demand for ketchup
Boycott - Company commits social blunder- consumers boycott
Consumer income rises - Demand for inferior goods drops as people have more money to spend
Consumer tastes change
Contraction - less spending decreases equilibrium GDP
Economics
How much you spend when your income increases
Calculate: Change in Spending / Change in Income
Economics
How much you save when income increases
Calculate: Change in Savings / Change in Income
Also equals 1 - Marginal Propensity to Consume
Economics
(1 / 1-MPC) x Change in Spending
Economics
As spending by consumers or the government increases- the demand curve increases (shifts right).
Economics
The increase in demand ends up being larger than the amount of additional income spent in the economy due to the multiplier effect.
One consumer spends money- which:
*Increases the income of a business
*Increases the income of a vendor
*Increases income of employees
*Increases tax revenue
Economics
% Change in Quantity Demand / % Change in Price
Economics
Price increases- Revenue decreases
Price decreases- Revenue increases
Economics
Many substitutes (luxury items)
Considered elastic if elasticity is greater than 1
10% drop in demand / 8% increase in price : 1.25 (Elastic)
Price increases- Revenue decreases
Price decreases- Revenue increases
Economics
Price increases- Revenue increases
Price decreases- Revenue decreases
Economics
Few substitutes (groceries- gasoline)
Considered inelastic if coefficient of elasticity is less than 1
5% drop in demand / 10% increase in price : .5 (inelastic)
Price increases- Revenue increases
Price decreases- Revenue decreases
Economics
Total revenue will remain the same if price is increased
Considered unitary if coefficient of elasticity : 1
Economics
% Change Quantity Demanded / % Change in Income
Normal goods greater than 1 (demand increases more than income)
Inferior goods less than 1 (demand increases less than income)
Economics
Interest rates increase
Reduced demand for loans
Reduced demand for houses- autos- etc.
Value of bonds and fixed income securities decrease
Inferior good demand to increase
Foreign goods more affordable than domestic
Demand for domestic goods decrease
Economics
Overall spending increases
Demand increases (shifts right)
Market equilibrium price increases
Economics
Overall production costs increase
Supply decreases (shifts left)
Market equilibrium price increases
Note: Demand-Pull and Cost-Push Inflation BOTH result in market equilibrium price to increase
Economics
The price where Quantity Supplied : Quantity Demanded
Economics
When Marginal Revenue : Marginal Cost
Economics
Causes a surplus if above equilibrium price.
