CHAPTER 2: THINKING LIKE AN ECONOMIST

Flashcard 7

Term: Production Possibilities Frontier
Definition: A graph that shows the best way to use limited resources to produce two different goods.

Flashcard 8

Term: Points on a Production Possibilities Frontier

  • On the curve: The economy is using resources efficiently.

  • Inside the curve: The economy is wasting resources or not using them fully.

  • Outside the curve: The economy does not have enough resources to produce at this level.

Flashcard 9

Term: Shifts in the Production Possibilities Frontier

  • If the curve shifts to the right: More resources, better technology, or economic growth.

  • If the curve shifts to the left: Loss of resources, war, or economic decline.


CHAPTER 4: SUPPLY AND DEMAND

Flashcard 10

Term: Market
Definition: Any place where buyers and sellers exchange goods or services.

Flashcard 11

Term: Law of Demand
Definition: When prices increase, quantity demanded decreases and when prices decrease, quantity demanded increases, assuming all other factors remain the same.

Flashcard 12

Term: Demand Curve
Definition: A graph that slopes downward from left to right, showing the relationship between price and quantity demanded.

Flashcard 13

Term: Factors That Shift Demand

  1. Consumer Preferences: If a good becomes popular, demand increases.

  2. Income Changes:

    • Normal Goods: Demand increases when income increases.

    • Inferior Goods: Demand decreases when income increases.

  3. Prices of Related Goods:

    • Substitutes: If the price of Coca-Cola rises, demand for Pepsi increases.

    • Complements: If gasoline prices rise, demand for cars decreases.

  4. Expectations: If people expect prices to rise in the future, they buy more now.

  5. Number of Buyers: If more people enter the market, demand increases.

Flashcard 14

Term: Law of Supply
Definition: When prices increase, quantity supplied increases and when prices decrease, quantity supplied decreases, assuming all other factors remain the same.

Flashcard 15

Term: Supply Curve
Definition: A graph that slopes upward from left to right, showing the relationship between price and quantity supplied.

Flashcard 16

Term: Factors That Shift Supply

  1. Input Costs: If the price of raw materials increases, supply decreases.

  2. Technology Improvements: More efficient production increases supply.

  3. Government Policies: Taxes reduce supply, while subsidies increase supply.

  4. Expectations: If suppliers expect higher prices in the future, they reduce supply now.

  5. Number of Sellers: More sellers increase supply.

Flashcard 17

Term: Market Equilibrium
Definition: The point where quantity demanded equals quantity supplied, meaning there are no shortages or surpluses.

Flashcard 18

Term: Shortage
Definition: When demand is greater than supply, causing prices to rise.

Flashcard 19

Term: Surplus
Definition: When supply is greater than demand, causing prices to fall.


CHAPTER 5: ELASTICITY

Flashcard 20

Term: Price Elasticity of Demand
Definition: Measures how much quantity demanded changes when price changes.
Formula:

%change in quantity demanded%change in price\frac{\% \text{change in quantity demanded}}{\% \text{change in price}}%change in price%change in quantity demanded​

Flashcard 21

Term: Elastic Demand
Definition: Quantity demanded changes a lot when price changes.

Flashcard 22

Term: Inelastic Demand
Definition: Quantity demanded changes only a little when price changes.

Flashcard 23

Term: Total Revenue and Elasticity

  • If demand is elastic: Raising price decreases total revenue.

  • If demand is inelastic: Raising price increases total revenue.

Flashcard 24

Term: Income Elasticity of Demand
Definition: Measures how demand changes when income changes.
Formula:

%change in quantity demanded%change in income\frac{\% \text{change in quantity demanded}}{\% \text{change in income}}%change in income%change in quantity demanded​

  • Positive result: Normal Good.

  • Negative result: Inferior Good.

Flashcard 25

Term: Cross-Price Elasticity of Demand
Definition: Measures how demand for one good changes when the price of another good changes.
Formula:

%change in quantity demanded of Good 1%change in price of Good 2\frac{\% \text{change in quantity demanded of Good 1}}{\% \text{change in price of Good 2}}%change in price of Good 2%change in quantity demanded of Good 1​

  • Positive result: Substitutes.

  • Negative result: Complements.


GOVERNMENT POLICIES AND MARKET EFFECTS

Flashcard 26

Term: Price Ceiling
Definition: A maximum price set by the government, which can lead to shortages.
Example: Rent control laws limit how much landlords can charge for apartments.

Flashcard 27

Term: Price Floor
Definition: A minimum price set by the government, which can lead to surpluses.
Example: Minimum wage laws set a base pay for workers.

Flashcard 28

Term: Taxes and Subsidies

  • Taxes on goods: Increase prices and reduce demand.

  • Subsidies: Lower costs for producers and increase supply.

Flashcard 29

Term: Deadweight Loss
Definition: The lost economic benefits caused by market inefficiencies, such as taxes or price controls.
