Assume that stock market returns have the market index as a common factor, and that all stocks in the economy have a beta of 1.7 on the market index. firm-specific returns all have a standard deviation of 35%. suppose that an analyst studies 20 stocks and finds that one-half of them have an alpha of +2.6%, and the other half have an alpha of −2.6%. suppose the analyst invests $1.0 million in an equally weighted portfolio of the positive alpha stocks, and shorts $1 million of an equally weighted portfolio of the negative alpha stocks. a. what is the expected profit (in dollars) and standard deviation of the analyst’s profit?

Suppose there are three types of consumers who attend concerts at your university’s performing arts center: students, staff, and faculty. each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. there is a fixed cost of $1,000 to put on a concert, but there are essentially no variable costs. for each concert: i. there are 140 students willing to pay $20. (ii) there are 200 staff members willing to pay $35. (iii) there are 100 faculty members willing to pay $50. a) if the performing arts center can charge only one price, what price should it charge? what are profits at this price? b) if the performing arts center can price discriminate and charge two prices, one for students and another for faculty/staff, what are its profits? c) if the performing arts center can perfectly price discriminate and charge students, staff, and faculty three separate prices, what are its profits?

Within the relevant range, if there is a change in the level of the cost driver, then a. total fixed costs will remain the same and total variable costs will change b. total fixed costs will change and total variable costs will remain the same c. total fixed costs and total variable costs will change d. total fixed costs and total variable costs will remain the same

The research of robert siegler and eric jenkins on the development of the counting-on strategy is an example of design.
