This firm finances its activities by selling two types of claims (or financial securities). An investor who buys the first type of security earns: min (x,F) An investor who buys the second gets a payoff of: max(x-F,0) Here x is random. By this I mean that sometimes is large and sometimes small. F, on the other hand, is fixed and equal to $500. a) Draw a graph of the payoff that an investor gets for each claim. Put the random income x on the horizontal axis and the payoff on the vertical axis. b) In light of the discussion of bonds versus stocks, how would you label the first security? How about the second security? Interpret F and x. c) Suppose x can be either $7000 with probability 0.5 or $600 with probability 0.5. Calculate the expected payoffs of both securities (Note: don’t worry about computing present values, just calculated the expected payoff in “future” prices). Question 2 (50 points): Let’s begin with a refresher about indifference curves and utility functions.
