Flashcards 1(16)
Define consumer surplus.
Consumer surplus is the difference between what consumers are willing to pay and what they actually pay.
Define producer surplus.
Producer surplus is the difference between what producers receive for a good and their minimum acceptable price.
True or False: Consumer surplus increases when prices rise.
False. Consumer surplus decreases when prices rise because consumers pay more and gain less benefit.
Fill in the blank: Producer surplus is maximized at __________.
equilibrium price.
What happens to consumer surplus at a price ceiling?
Consumer surplus may increase, as lower prices allow consumers to pay less.
Compare consumer surplus and producer surplus.
Consumer surplus benefits buyers; producer surplus benefits sellers. Both indicate economic welfare.
What is deadweight loss?
Deadweight loss is the loss of economic efficiency when equilibrium is not achieved.
True or False: An increase in demand leads to higher producer surplus.
True. Higher demand raises prices, increasing producer surplus.
Example of consumer surplus.
7 price → $3 consumer surplus.
Cause → Effect: Price floor in a market.
Cause: Price floor. Effect: Surplus of goods, reduced consumer surplus.
What is the formula for calculating consumer surplus?
Consumer Surplus = 1/2 × Base × Height (Area of triangle under demand curve.)
Define total surplus.
Total surplus is the sum of consumer surplus and producer surplus, indicating overall economic welfare.
Explain how subsidies affect producer surplus.
Subsidies increase producer surplus by raising effective prices received by producers.
What can cause a decrease in producer surplus?
Increased production costs or lower market prices can decrease producer surplus.
True or False: Price elasticity affects consumer surplus.
True. More elastic demand leads to greater changes in consumer surplus with price changes.
Identify a condition for maximizing total surplus.
Markets must operate at equilibrium to maximize total surplus.

Consumer surplus definition
The difference between what consumers are willing to pay and what they actually pay.
Producer surplus definition
The difference between the price producers receive and the minimum price they would accept.
True or False: Consumer surplus increases with higher prices.
False. Higher prices decrease consumer surplus as fewer consumers benefit.
Fill in the blank: Consumer surplus is represented by the area ___ the demand curve.
above, below the equilibrium price.
Calculate consumer surplus: Price is 15.
Consumer surplus = 10 = $5.
Comparison: Consumer surplus vs. Producer surplus
- Consumer: benefit to consumers. - Producer: benefit to producers.
Shifts in demand affect consumer surplus how?
An increase in demand raises consumer surplus; a decrease lowers it.
How does tax affect producer surplus?
Tax reduces producer surplus by lowering the effective price received.
What happens to surplus in a price ceiling?
Consumer surplus may increase, producer surplus decreases, leading to shortages.
True or False: Deadweight loss occurs when there is a market distortion.
True. Deadweight loss reduces total surplus in the market.
Example of deadweight loss.
A price floor leads to surplus of goods and lost trades.
Graph: Surplus areas in equilibrium.
Consumer surplus is the area above the price and below the demand curve; producer surplus is below the price and above the supply curve.
What indicates maximum consumer surplus on a graph?
The triangle formed between the demand curve and the equilibrium price.
Market equilibrium and total surplus relationship.
Total surplus is maximized at market equilibrium, where consumer and producer surplus are highest.
Effect of subsidies on producer surplus?
Subsidies increase producer surplus by raising the price received.
Calculate total surplus: CS = 30.
Total surplus = Consumer surplus + Producer surplus = 30 = $80.
