- Although there is no empirical evidence to strongly support this hypothesis, some financial journalists have claimed that British managers are short-sighted and overly risk averse, preferr ing to take on relatively safe projects that pay off quickly instead of taking on longerterm projects with less certain pay-offs. Assume the journalists are correct.a Explain why managers who use a single discount rate for valuing projects are likely to have a systematic bias against longer-term projects if the systematic risk of the cash flows of many long-term investment projects declines over time.b Discuss how the presence of strategic investment options affects the decisions to adopt long-term over short-term investments. Can you help with the understanding of question a and bA well known brokeage firm executive claimed that at least 22% of investors are currently confident of meeting their investment goals.How common are financial cost or contractual constraints associated with smartphone ownership?

(See D. Horsky and P. Swyngedouw, "Does it pay to change your company's name? A stock market perspective," Marketing Science v.6, pp. 320-35,1987.) Suppose that, to test the profitability of name changes in the more recent market (the past five years), we analyze the stock prices of a large sample of corporations shortly after they changed names, and we find that the mean relative increase in stock price was about 0.87 %, with a standard deviation of 16 %. Suppose that this mean and standard deviation apply to the population of all companies that changed names during the past five years. Complete the following statements about the distribution of relative increases in stock price for all companies that changed names during the past five years.
