Vito, the owner of Vito's Italian restaurant, asks for your advice. He currently sells 1,000 pizzas per month at a price of $12 per pizza. You estimate that the price elasticity of demand for pizza is -0.5. If he increases the price to $15, how much additional revenue would he earn?
1,125 13,125 (New TR) - 12,000 (Old TR)
Vito, the owner of Vito's Italian restaurant, asks for your advice. He currently sells 1,000 pizzas per month at a price of $12 per pizza. You estimate that the price elasticity of demand for pizza is -2. By how much would Vito's total revenue change if he cuts the price from $12 to $9.
1,500 % decrease = 12-9/12 = 25% % increase = -2 x 0.25 = 50% New Q demanded = 1000 x (1+.50) = 1,500 New Total Revenue = 1,500 pizzas x $9 (new price) Revenue change = 13,500 - 12,000
The Harrisonburg city government is considering imposing rent ceilings. Currently, one bedroom apartments rent for $1,200 per month, and there are 5,000 units rented. Assume that the price elasticity of demand is -0.20 and the price elasticity of supply is +1.2. How much of a shortage will there be if the government imposes a price ceiling of $900?
1,750 Q demanded - Q supplied 5,250 - 3,500
The Harrisonburg city government is considering imposing rent ceilings. Currently, one bedroom apartments rent for $2,000 per month, and there are 10,000 units rented. Assume that the price elasticity of demand is -0.40 and the price elasticity of supply is +.50. How much of a shortage will there be if the government imposes a price ceiling of $1,600?
1,800 % C in price = 1600- 2000/2000 = -20% % C in Q demanded = -.20 x -0.40 = 0.08 % C in Q supplied = -.20 x .50 = -0.10 New Q demanded = 10,000 x (1+0.08) = 10800 New Q supplied = 10,000 x (1-.10) = 9000 Shortage = 10,800-9000

The Harrisonburg city government is considering imposing rent ceilings. Currently, one bedroom apartments rent for $1,200 per month, and there are 5,000 units rented. Assume that the price elasticity of demand is -0.20 and the price elasticity of supply is +1.2. How many apartments are supplied if the government imposes a price ceiling of $900?
3,500 % C in price = 900-1200/1200 = -25% % C in Q demanded = -0.2 x -.25 = 5% % C in Q supplied = 1.2 x -.25 = -30% New Q supplied = 5,000 x (1-.30)
The table above shows Keira's utility from soup and sandwiches. The price of soup is $2 per cup and the price of a sandwich is $3. Suppose Keira's has $23 to spend on these goods. If Keira maximizes her utility, how many units of each good should she buy?
4 cups of soup and 5 sandwiches

The Harrisonburg city government is considering imposing rent ceilings. Currently, one bedroom apartments rent for $1,200 per month, and there are 5,000 units rented. Assume that the price elasticity of demand is -0.20 and the price elasticity of supply is +1.2. How many apartments are demanded if the government imposes a price ceiling of $900?

Assume that the price elasticity of demand is -0.20 and the price elasticity of supply is +1.2. How much of a surplus will there be if the government imposes a price floor of $5?
7,000 % C in price = 5-4/4 = 0.25 % C in Q demanded = -0.20 x 0.25 = -0.05 % C in Q supplied = 1.2 x 0.25 = 0.3 New Q demanded = 20,000 x (1-0.05) = 19000 New Q supplied = 20,000 x (1+0.3) = 26000 Surplus = 26,000 - 19,000

80 units of utility.
Vito, the owner of Vito's Italian restaurant, asks for your advice. He currently sells 1,000 pizzas per month at a price of $12 per pizza. You estimate that the price elasticity of demand for pizza is -0.5. How many pizzas will he sell if he increases the price to $15?
875 1000 x (1-% decrease) % increase = 15-12/12 = 25% % decrease = -0.5 x .25 = .125

Alan Krueger conducted a survey of fans at the 2001 Super Bowl who purchased tickets to the game for $325 or $400. Krueger found that (a) 94 percent of those surveyed would not have paid $3,000 for their tickets, and (b) 92 percent of those surveyed would not have sold their tickets for $3,000. These results are evidence of

According to an article in the Wall Street Journal, unlike airlines, even elite hotels don't have sophisticated systems that can react quickly to changes in demand. Even if they could, many hoteliers say people don't respond that much to lower rates.
