Suppose the governor of California has proposed increasing toll rates on California's
toll roads, and has presented two possible scenarios to implement these increases.
Following are projected data for the two scenarios for the California toll roads:
Scenario 1: Toll rate in 2015: $10.00. Toll rate in 2019: $22.50
For every 100 cars using the toll roads in 2015, only 81.6 cars will use the toll roads in
2019.
Scenario 2: Toll rate in 2015: $10.00. Toll rate in 2019: $17.50
For every 100 cars using the toll roads in 2015, only 96.2 cars will use the toll roads in
2019.
a. Using the midpoint formula, calculate the price elasticity of demand for Scenario 1
and Scenario 2.
b. Assume 10,000 cars use California toll roads every day in 2015. What would be the
daily total revenue received for each scenario in 2015 and in 2019?
c. Is demand under Scenario 1 and under Scenario 2 price elastic, inelastic, or unit
elastic. Briefly explain.
(For above questions, assume that nothing other than the toll change occurs during the
time frame listed that would affect consumer demand.)

Figure 14-3
Rainbow Writer (RW) is a small online company selling a highly rated software
package for engraving words onto objects produced by 3D printers. The firm currently
earns a profit of $2 million per year selling its package exclusively on its Website.
Odeon, the producer of the most popular 3D printers has expressed interest in bundling
Rainbow Writer's product with its printers. Odeon expects that bundling would further
boost its sales and allow it to sell its printers at a higher price, thus raising its profits
beyond its current profit of $12 million. Figure 14.3 shows the decision tree for the
Rainbow Writer-Odeon bargaining game.
Refer to Figure 14-3. What is the equilibrium outcome in this game and is this a
subgame-perfect equilibrium?
A) Odeon's offer of $40 per copy of the software package is accepted and this is a
subgame-perfect equilibrium.
B) In the equilibrium, Odeon offers $40 per copy of the software package and is
accepted but this is not a subgame-perfect equilibrium.
C) In the equilibrium, Odeon offers $30 per copy of the software package and is
rejected, and this is a subgame-perfect equilibrium.
D) There is no equilibrium in this game.

should be treated as part of the product's value.

price of a product in their consumption decisions.
D) Sunk costs have a higher opportunity cost than costs that can be recovered.
