- Problem 5 The MNO Corporation is preparing for its stockholder meeting on May 15, 2013. It sent out proxies to its stockholders on March 15 and asked stockholders who plan to attend the meeting to respond. To plan for a sufficient number of information packages to be distributed at the meeting, as well as for refreshments to be served, the company has asked you to forecast the number of attending stockholders. By April 15, 378 stockholders have expressed their intention to attend. You have available the following data for the last 6 years for total attendance at the stockholder meeting and the number of positive responses as of April 15: Year Positive Responses Attendance 2007 322 520 2008 301 550 2009 398 570 2010 421 600 2011 357 570 2012 452 650 1.

The company's economist, having investigated a large number of past data, has established the following equation of demand for these cabinets: Q=10,000+6013-100P+50C Q=Annual number of cabinets sold B = Index of nonresidential construction P = Average price per cabinet charged by OE C=Average price per cabinet charged by OE's closest competitor It is expected that next year's nonresidential construction index will stand at 160, OE's average price will be $40, and the competitor's average price will be $35. 1. Forecast next year's sales. 2. What will be the effect if the competitor lowers its price to 832? If it raises its price to $36? 3. What will happen if OE reacts to the decrease mentioned in part b by lowering its price to $37? 4. If the index forecast was wrong, and it turns out to be only 140 next year, what will be the effect on OE's sales? If not, what does it measure?arrow_forwardName: Problem 1: Managerial Economics, Assignment 5 April 20, 2025 If the sales of your company have grown from $500,000 five years ago to $1,050,150 this year, what is the compound growth rate?

- 1. In this question, assume all dollar units are real dollars in billions. For example, $100 means $100 billion. Argentina thinks it can find $105 of domestic investment projects with a marginal product of capital (MPK) equal to 10% (each $1 invested in year 0 pays off $0.10 in every later year). Assume a world real interest rate r*is 5%, and initial external wealth W (W in year -1) is 0. a. You find that the formula on the lecture slide: > r*, which means that a country will ΔΟ AK take on investment projects as long as the marginal product of capital (MPK) is at least as high as the real interest rate. Using this formula, answer if Argentina should conduct the project. b. If the projects are not done, GDP = Q = C = $200 in all years. Compute the present value of Q and C. c. If Argentina conducts the projects (investing $105), what is the present value of Q and C? d. If Argentina conducts the projects, what is the present value of C? Is Argentina better off with the investment?arrow_forward2. Consider a world of two countries: Highland (H) and Lowland (L). Each country has an average output of 9 and desires to smooth consumption. All income takes the form of capital income and is fully consumed each period. Initially, there are two states of the world: Pandemic (P) and Flood (F) each occurring with 50% probability. Pandemic affects Highland and lowers the output there to 8, leaving Lowland unaffected with an output of 10. Flood affects Lowland and lowers the output there to 8, leaving Highland unaffected with an output of 10. a. Assume that households in each country own the entire capital stock of their own land. Fill in the numbers on the following table. Pandemic Highland's income Lowland's income Flood Variation about the mean b. Assume that each country owns 50% of the other country's capital.

How many calls with a strike of $55 could they buy for the same $1,000, and how much would they make if the share price increased to $60? c. How much would they make (or lose) from the stock and from the calls if the share price declined to $40? 4. What is the premium on a call with a strike of $0.01?
