Question

1. April, Barbara, and Cathy are considering whether or not to purchase tickets to see the musical Wicked. April would pay as much as $75, Barbara would pay as much as $55, and Cathy would pay as much as $40 for a ticket. If the actual price is $45, how much consumer surplus is created when all three women purchase their tickets? 2. If government takes no action in response to a negative externality, is it likely that this activity will take place more or less than the socially optimal amount? 3. Assume a seller would be willing to accept a price as low as $100 each for 5 machines, but the buyer offers a price of $150 each, which the seller accepts. Calculate producer surplus in this example: 4. Use the graph below to answer the question: Calculate consumer surplus in this market assuming the price of the product is $4:

Explanation / Answer

1. Consumer surplus is the difference between the maximum price we are willing to pay for a good or service and the price we actually pay for the same.

April's consumer surplus = $75 - $45 = $30.

Barbara's consumer surplus = $55 - $45 = $10

Cathy's consumer surplus = $40 - $45 = -$5

So, the total consumer surplus = $30 + $10 + (-$5) = $40 - $5 = $35.
