Consider a stock with a price of $120 and a standard deviation of 30 percent. The stock will pay a dividend of $5 in 40 days and a second dividend of $5 and 140 days. The current risk-free rate is 6 percent per annum. An American call on this stock has an exercise price of $150 and expires in 100 days.
Price the American call option using the Black-Scholes Model. Show all calculations

4.

1. (a) Explain the features of an interest rate swap, illustrating your answer with a simple numerical example. What benefits could a firm obtain from using interest rate swaps? (150 words)

2. (b) Why must the price of an American call option on a stock that pays no dividends always be higher than its intrinsic value? How can the price of an American call option be determined from the price of a European call option on the same stock with the same time to expiry? Explain. (180 words)

3. (c) Is it ever optimal to exercise an American put option before its expiration date, assuming the underlying stock pays no dividends? Explain your answer with reference to the put-call parity relationship. (150 words)

Harris Interactive® conducted a poll of American adults in August of 2011 to study the use of online medical information. Of the 1,019 randomly chosen adults, 60% had used the Internet within the past month to obtain medical information.

1. Use the results of this survey to create an approximate 95% confidence interval estimate for the percentage of all American adults who have used the Internet to obtain medical information in the past month.
2. Calculate the 90% confidence interval.
3. Which confidence interval has the smaller margin of error? Why does this make sense?
4. Which confidence interval is more likely to contain the true percentage of all American adults who have used the Internet to obtain medical information in the past month? Why do you think so?

Since the 1980s, the US apparel manufacturing industry has moved to Southeast Asian countries to take advantage of low cost of labor. The American consumers are enjoying the cheap apparel made in these countries however this benefit comes with a cost to the people who work in these textile factories. The collapse of the Bangladesh textile factory that caused the death of over a thousand people in 2013 made a huge echo in the western world. In this discussion forum, we want to take a deeper look at the ethical issues in the global environment. Do American companies have a responsibility to ensure the health and safety of the workers who manufacture the clothing they sell although labor laws are not enforced in these countries? Please research recent news and give other examples. Are American firms committed to increasing labor standards in their host countries?

1. According to well-developed national norms, the mean of scores on the OB Anxiety scale among American adults equals 50 and the standard deviation of scores on this inventory equals 15. A researcher wants to assess whether adults living in Canada differ in anxiety from American adults. She has no a priori hypothesis about whether Canadians have higher or lower values (i.e., the key thing of interest at this stage is whether the Canadians simply differ from Americans) She administers the OB scale to 121 randomly sampled Canadian adults. The mean OB score for this sample is 52.5. She assumes that the population standard deviation of Canadian scores is the same as the population standard deviation of American scores.

a. What are her null and alternative hypotheses?

b. Conduct a statistical test of the null hypothesis.

  "Popular music" is music that is mass-reproduced and disseminated via the mass media, that has at various times been listened to large numbers of Americans, and that typically draws upon a variety of preexisting musical traditions."

Consider an option on a non-dividend paying stock when the stock price is $67, the exercise price is $61, the risk-free rate is 0.5%, the market volatility is 30% and the time to maturity is 6 months. Using the Black-Scholes Model

(i) Compute the price of the option if it is a European Call.

(ii) Compute the price of the option if it is an American Call.

(iii) Compute the price of the option if it is a European Put.

(iv) Assuming two dividend payments $1.75 and $2.75, two months and five months from now, compute the price of the option if it is a European Call.

(v) Refer to the dividend information provided in (iv) above. Compute the price of the option if it is an American Call. Provide a graphical illustration to demonstrate how the price of this American Call and the payoff from the same change with respect to changes in the stock price.
