Suppose there are n assets which are uncorrelated. (They might be n different "wild cat" oil well prospects.) You may invest in any one, or in any combination of them. the mean rate of return r is the same for asset but the variances are different. The return on asset i has a variance σi^2 for i= 1,2,...n

a. Describe the efficient set for this situation
b. Write a formula for the minimum-variance point. Express your result in terms of
n
σ^2= ( Σ 1/σi^2)
i=1

White truffles are a very prized and rare edible fungus that grow naturally in the countryside near alba, italy. suppose that it costs $200 per day to search for white truffles. on an average day, the total number of white truffles (t) found in alba is t = 20x − x 2 , where x is the number of people searching for white truffles on that day. white truffles can be sold for $100 each. if there is no regulation, how many more people will be searching for white truffles than the socially optimal number?
