The SCP model dates back to the pioneering work of the Harvard economist Edward Mason, in the1930s, and oneof his doctoral student Joseph Bain, in the 1950s. Originally used by the US government in craftingantitrust policy,the model gained popularity among corporate strategists when Michael Porter (Competitive Strategy,1980) used itas an analytic tool for businesses striving to compete within a market. The model's original formdepicts theinfluence of an industry's structure (for example, the growth of demand and barriers to entry) on theconduct ofproducers (pricing, for example) and the performance of both the industry and the producers.

Suppose you currently have a portfolio of three stocks, A, B, and C. You own 500 shares of A, 300 of B, and 1000 of C. The current share prices are 42.76, 81.33, and, 58.22, respectively. You plan to hold this portfolio for at least a year. During the coming year, economists have predicted that the national economy will be awful, stable, or great with probabilities 0.2, 0.5, and 0.3. Given the state of the economy, the returns (one-year percentage changes) of the three stocks are independent and normally distributed. However, the means and standard deviations of these returns depend on the state of the economy, as indicated in the file P11_23.xlsx. a. Use @RISK to simulate the value of the portfolio and the portfolio return in the next year. How likely is it that you will have a negative return? How likely is it that you will have a return of at least 25%? b. Suppose you had a crystal ball where you could predict the state of the economy with certainty. The stock returns would still be uncertain, but you would know whether your means and standard deviations come from row 6, 7, or 8 of the P11_23.xlsx file. If you learn, with certainty, that the economy is going to be great in the next year, run the appropriate simulation to answer the same questions as in part a. Repeat this if you learn that the economy is going to be awful. How do these results compare with those in part a?
If a monopolist produces q units, she can charge 400 4q dollars per unit. The variable cost is 60 per unit. a. How can the monopolist maximize her profit? b. If the monopolist must pay a sales tax of 5% of the selling price per unit, will she increase or decrease production (relative to the situation with no sales tax)? c. Continuing part b, use SolverTable to see how a change in the sales tax affects the optimal solution. Let the sales tax vary from 0% to 8% in increments of 0.5%.
The stocks in Example 7.9 are all positively correlated. What happens when they are negatively correlated? Answer for each of the following scenarios. In each case, two of the three correlations are the negatives of their original values. Discuss the differences between the optimal portfolios in these three scenarios. a. Change the signs of the correlations between stocks 1 and 2 and between stocks 1 and 3. (Here, stock 1 tends to go in a different direction from stocks 2 and 3.) b. Change the signs of the correlations between stocks 1 and 2 and between stocks 2 and 3. (Here, stock 2 tends to go in a different direction from stocks 1 and 3.) c. Change the signs of the correlations between stocks 1 and 3 and between stocks 2 and 3. (Here, stock 3 tends to go in a different direction from stocks 1 and 2.) EXAMPLE 7.9 PORTFOLIO SELECTION AT PERLMAN BROTHERS Perlman Brothers, an investment company, intends to invest a given amount of money in three stocks. From past data, the means and standard deviations of annual returns have been estimated as shown in Table 7.2. The correlations among the annual returns on the stocks are listed in Table 7.3. The company wants to find a minimum-variance portfolio that yields a mean annual return of at least 0.12.

Show cells in excel with step by step using solver and the sum product function show how to calculate weighted risk Wall Street firms commonly use linear programming models to select their bond portfolios. A firm is considering the following 5 bonds: Bond Annual Return rate (%) Risk measure Bond 9.2 5 Bond 5 3 Bond 6.1 2 Bond 3.5 4 Bond 1.2 1 In the table above, “risk measure” has a value between 1 and 5 with 5 indicating the riskiest bond and 1 the least risky bond. The firm has a budget of 1 million dollars for this investment. The firm wants to decide its investments in the 5 bonds to maximize the expected return of the portfolio, subject to constraints listed below: The weighted average risk of the portfolio should not exceed 4. At least 30% of the total investment can be invested in bond 3. To diversify the portfolio, the investment on each bond should be at least 10% of the total investment. The sum of investments made in…

“Good Intentions” (GI) company produces two products, which it sells on both a cash and credit basis. Revenues from credit sales will not have been received but are included in determining profit earned during the current six-month period. Sales during the next six months can be made either from units produced during the next six months or from the beginning inventory. Relevant information about products one and two is as follows. During the next six months, at most 150 units of product type 1 can be sold on a cash basis, and at most 100 units of product 1 can be sold on a credit basis. It costs £35 to produce each unit of product type 1, and each sells for £40. A credit sale of a unit of product 1 yields £0.50 less profit than a cash sale (because of delays in receiving payment). Two hours of production time are needed to produce each unit of product 1. At the beginning of the six-month period, 60 units of product 1 are in the inventory. During the next six months, at most 175 units…

It is often difficult to estimate the expected future dividend growth rate for use in estimating the cost of existing equity using the DCF or DG approach. In general, there are three available methods to generate such an estimate: • Carry forward a historical realized growth rate, and apply it to the future. • Locate and apply an expected future growth rate prepared and published by security analysts. • Use the retention growth model. Suppose Johnson is currently distributing 45% of its earnings in the form of cash dividends. It has also historically generated an average return on equity (ROE) of 20%. Johnson’s estimated growth rate is %.
An investment advisor at Shore Financial Services wants to develop a model that can be used to allocate investment funds among four alternatives: stocks, bonds, mutual funds, and cash. For the coming investment period, the company developed estimates of the annual rate of return and the associated risk for each alternative. Risk is measured using an index between 0 and 1, with higher risk values denoting more volatility and thus more uncertainty. Investment Annual Rate of Return (%) Risk Stocks. 10 0.8 Bonds 3 0.2 Mutual funds 4 0.3 Cash 1 0.0 Because cash is held in a money market fund, the annual…
