Common stock value: all growth models you are evaluating the potential purchase of a small business currently generating $42,500 of after-tax cash flow (d0 = $42,500). on the basis of a review of similar-risk investment opportunities, you must earn an 18% rate of return on the proposed purchase. because you are rel- atively uncertain about future cash flows, you decide to estimate the firm’s value us- ing several possible assumptions about the growth rate of cash flows. a. what is the firm’s value if cash flows are expected to grow at an annual rate of 0% from now to infinity? b. what is the firm’s value if cash flows are expected to grow at a constant annual rate of 7% from now to infinity? c. what is the firm’s value if cash flows are expected to grow at an annual rate of 12% for the first 2 years, followed by a constant annual rate of 7% from year 3 to infinity?

The hawthorne works was a large western electric factory with 45,000 employees. during the 1920s and 1930s, hawthorne works was the site of some well-known industrial studies. in one of the studies, researchers investigated the impact of different working conditions on worker productivity. prior to the start of the study, researchers secretly measured workers' productivity for several weeks. then researchers chose two workers, who then chose their own teams. the teams were separated from the general workforce and completed their work in different experiment rooms where the researchers could observe them more easily. over a 5-year period researchers manipulated the structure of the workday for each team (number and duration of breaks and number of hours per shift). for each of these changes in working conditions, the researchers measured the effect on productivity. for some conditions, such as frequent short breaks, workers rebelled by intentionally decreasing productivity.why did the researchers secretly measure the workers' productivity before creating the two treatment groups? a, to create similar treatment groups so that a cause-and-effect relationship could be establishedb, to draw conclusions about the productivity of all workers in the plant based on the test groupsc, to directly control for confounding variablesd, to provide a baseline for measuring worker productivity
