Chapter 1 - ECON Flashcards
A demand curve shifts due to
factors OTHER than a change in price:
An upward demand curve shift is in which direction?
To the right… called a direct relationship. Same with upward Supply curve shifts. To the left would be a downward shift for both.
Examples of upward shifts in demand (more demand)?
- The price of a substitute good looking more attractive (an increase in the price of hamburgers would increase the demand for hot dogs
- Expectations of price changes - consumers may be more likely to buy something now because they EXPECT prices to rise.
- Income Increases - When income increases, demand for certain items increase
- Extent of the market - increase in size of the market because of things like removal of trade barriers, baby boom increasing demand for abby goods, large inflow of immigrants, etc
Examples of downward shifts in demand
- Price of a complement good goes up - If bun prices are up, hot dog demand would go down
- Income increases - for certain goods, demand goes down as a person gains more wealth
- Consumer boycott - If effective, would temporarily decrease demand.
What is an “indeterminate relationship”
A factor that can cause demand to shift up or down. The best example is a change in consumer taste
Price elasticity of demand:
how responsive or sensitive Quantity Demanded of a good or service is to a change in price
formulas to measure price elasticity of demand
If Ed = 1: Unit Elastic. No change in total revenue
If Ed > 1: Elastic. So if Price goes up, Total Revenue can go down
If Ed<1: Inelastic. So if price goes up, total revenue would go up.
Elastic vs Inelastic
- Elastic: meaning consumers are FLEXIBLE. They are willing to go to other products
- Inelastic: customers are NOT flexible. They want this thing no matter what the price. EG - Cancer treatment
Examples of demand elasticity
Assume a firm can sell 110 units for $9 per unit. Company considering a price increase of $2 per unit
Is price or Quantity the numerator?
QUANTITY. Same with Income Elasticity:
Pectentage change in QUANTITY/ Percentage change in income
Direct relationships making supply go up:
- More Number of Producers
- Government subsidies
- Price expectations - “If producers expect higher prices, producers will increase their quantity supplied at any given price”
- Reductions in costs of production and technological advances
An inverse relationship that would make supply go down:
- Increases in production costs
- Prices of other products supplied - if producing product A is more profitable then producing product B, companies will decrease Quantity Supplied of company B
What is the Price Elasticity of Supply
Measure of how sensitive quantity supplied of a good or service is to a change in price or cost.
Price ceiling below equilibrium
A price ceiling is the MAXIMUM price a seller can charge.
POR FAVOR do not confuse the price ceiling and floor. What are they and where do they go?
The price ceiling and floor are results of government intervention in market prices:
- A price floor is ABOVE equilibrium price. (on top)
- A price ceiling is BELOW equilibrium price (on the bottom)
Do not get confuzzled and think that the ceiling is top and floor is on the bottom.
Explain the price ceiling and why it seems like it would help consumers but acutally hurt them?
The government mandates the price to be BELOW equiligrium price. Think of Gas. If ceiling was made $1, consumers would want it at that low price, so quantity demanded is high. However, because the selling price is so low, quantity supplied is going to fall because which gas company would want to sell something so low? Thus, quantity demanded is usually high and if the gas companies decide not to produce much gas to sell, there is a SHORTAGE which would really mess up consumers
Explain the floor, and why it seems like it would help businesses but actually not?
A government imposes a price floor when, for example, it wants to help farmers for a certain crop and say “their prices sold for corn needs to be higher”. Thus, farmers would obv want to produce more things sold at a higher price. But think back to a consumer point of view: who the hell would want to buy corn at such a high price? Thus, quantity supplied is very high and if consumers demand is low there could be a SURPLUS
What leads to a shortage?
Price Ceiling - Shortage
Price Floor - Surplus

by the way - what is Price (or Market) Equilibrium?
where quantity supplied = quanitity demanded. The point where the Supply and Demand curve meet. In other words, there is “adequate supply to satisfy buyers and adequate demand to allow suppliers to sell their output”. All goods offered for sale will be sold.
Law of diminishing marginal utility
The more a consumer consumes a particular product, the less satisfying will be the next unit of that product. “the twentieth oreo doesn’t taste as good as the first one” (jk)
Perfect (Pure) Competition:
- Large number of sellers, EACH of which is too small to affect the overall market price
- All firms sell a largely identical product (HOMOGENOUS)
- There is no non-price competition (no adverising)
- Each individual firm faces a demand curve that is PERFECTLY ELASTIC. Thus it is more horizaontal
Pure Monopoly:
- Only one producer
- No close substitutes are availible
- There blocked entry (eg a patent)
- The firm’s demand curve is substantially downward sloping (almost vertical)
Natural Monopoly
“there are very high fixed costs or other barriers to entry in getting started in a certain business or delivering a product or service.” Thus, “it is more efficient for one business to deliver a product than multiple businesses. In these situations, there are often government regulations to prevent high prices and corruption. This efficiency results in lower average costs for us.”
Eg - Public Utilities
