Consider a call option on a stock that does not pay dividends.
The stock price is $100 per share, and the risk-free interest rate is 10%.
The call strike is $100 (at the money).
The stock moves randomly with u=2 and d=0.5.
1. Write the system of equations to replicate the option using A shares and B bonds.
2. Solve the system of equations and determine the number of shares and the number of bonds
needed to replicate the option. Show your answer with 4 decimal places (x.xxxx); do not
round intermediate calculations. This is easy to do in Excel.
A =
B =
3. Use A shares and B bonds from the prior question to calculate the premium on the option.
Again, do not round intermediate calculations and show your answer with 4 decimal places.
Call premium =

Suppose that the two nations face the following benefits of pollution, B, and costs of abatement, C: BN = 10, Bs = 7; CN = 5, Cs = 4. Further assume that if the nation chooses to abate pollution, it still receives the benefits of pollution but now must pay the cost of abatement as well. a. Identify the payoffs that accrue to each nation under the four different possible outcomes of the game and present these payoffs in the normal form of the game. b. Recall that the term dominant strategy defines the condition that a player in a game would prefer to play that strategy (in this case either pollute or abate) regardless of the strategy chosen by the other player in the game. Does either nation have a dominant strategy in this game? If so, what is it? c. Identify the Nash equilibria, or non-cooperative equilibria, of this game.arrow_forward
- agrody calming Inted 001 and me 2. A homeowner is concerned about the various air pollutants (e.g., benzene and methane) released in her house when she cooks with natural gas. She is considering replacing her gas oven and stove with an electric stove comprising an induction cooktop and convection oven. The new appliance costs $900 to purchase and install. Capping the old gas line costs an additional $150 (a one-time fee). The old line must be inspected for leaks each year after capping, at a cost of $35 for each inspection. a. If the homeowner plans to remain in the house for four more years and the discount rate is 4%, what is the minimum present value of the benefits that the homeowner would need to experience for this purchase to be justified based on its private net sub present value? b. While trying to understand how she might express the value of reduced exposure to indoor air pollutants in dollar terms, the homeowner consulted the EPA website and found estimates provided by…arrow_forwardAfter the ban is imposed, Joe’s firm switches to the more expensive biodegradable disposable cups. This increases the cost associated with each cup of coffee it produces. Which cost curve(s) will be impacted by the use of the more expensive biodegradable disposable cups? Why? Which cost curve(s) will not shift, and why not? Please use the table below to answer this question. For the second column (“Impacted? If so, how?”), please use one of the following three choices: No shift; Shifts up (i.e., increases: at nearly any given quantity, the cost goes up); or Shifts down (i.e., decreases: at nearly any given quantity, the cost goes down). $ Cost Curve Impacted? If so, how? Explanation of the Shift: Why or Why Not AFC No shift. Fix costs stay the same, regardless of quantity. Fixed cost is calculated as Fixed Cost/Quantity. Since fixed costs remain unchanged, AFC stays the same for each quantity. MC Shifts up. Since the biodegradable cups are more expensive, the…arrow_forwardStyrofoam is non-biodegradable and is not easily recyclable. Many cities and at least one state have enacted laws that ban the use of polystyrene containers. These locales understand that banning these containers will force many businesses to turn to other more expensive forms of packaging and cups, but argue the ban is environmentally important. Shane owns a firm with a conventional production function resulting in U-shaped ATC, AVC, and MC curves. Shane's business sells takeout food and drinks that are currently packaged in styrofoam containers and cups. Graph the short-run AFC0, AVC0, ATC0, and MC0 curves for Shane's firm before the ban on using styrofoam containers.arrow_forward
