Unit 4 Homework – Template Problem 1Suppose that the U.S. Department of Agriculture (USDA) administers the price floor for cheese, set at $0.17 per pound of cheese. (The price floor is officially set at $16.10 per hundredweight of cheese. One hundredweight is 100 pounds.) At that price, according to data from the USDA, the quantity of cheese produced in 2009 by U.S. producers was 212.5 billion pounds, and the quantity demanded was 211 billion pounds. To support the price of cheese at the price floor, the USDA had to buy up 1.5 billion pounds of cheese. The accompanying diagram shows supply and demand curves illustrating the market for cheese.In the absence of a price floor, how much consumer surplus is created? How much producer surplus? What is the total surplusWith the price floor at $0.17 per pound of cheese, consumers buy 211 billion pounds of cheese. How much consumer surplus is created now?With the price floor at $0.17 per pound of cheese, producers sell 212.5 billion pounds of cheese (some to consumers and some to the USDA). How much producer surplus is created now?Problem 2The accompanying table shows the price and yearly quantity sold of ice cream cones on Sidfield Island.Price of Ice Cream Cones Quantity of Ice Cream Cones Demanded$1 3000$2 2400$3 1600$4 800Using the midpoint method (show your work), calculate the price elasticity of demand when the price of an ice cream cone rises from $1 to $2. What does this estimate imply about the price elasticity of demand for ice cream cones?b. Using the midpoint method (show your work), calculate the price elasticity of demand when the price of an ice cream cone rises from $3 to $4. What does this estimate imply about the price elasticity of demand for ice cream cones?c. Notice that the estimates from (a) and (b) above are different. Why do price elasticity of demand estimates change along the demand curve?
