- Suppose that a firm's sales were $3,750,000 five years ago and are $5,250,000 today. What was the geometric mean growth rate in sales over the past five years?The table below gives the annual sales (in millions of S) of a product.Table 217 of the 2006 U.S. Statistical Abstract shows that, among all 25–34 year olds, the average annual earnings of a high school graduate with no further education was $26,073 while the average annual earnings of a college graduate with no further education was $43,794 in 2003. a. Assuming college requires five years, show that the annual return to each year of college education averages 10.9 percent. b. It is typically thought that this type of calculation of the returns to schooling is biased because it doesn’t take into account innate ability (i.e., ability in the workplace not due to college) or innate motivation. If this criticism is true, is the actual return to each year of a college education more than or less than 10.9 percent?

Show the solutionJohn Kittle, an independent insurance agent, uses a five-year moving average to forecast the number of claims made in a single year for one of the large insurance companies he sells for. He has just discovered that a clerk in his employ incorrectly entered the number of claims made four years ago as 1,400 when it should have been 1,200.a. What adjustment should Mr. Kittle make in next year’s forecast to take into account the corrected value of the number of claims four years ago?b. Suppose that Mr. Kittle used simple exponential smoothing with a = .2instead of moving averages to determine his forecast. What adjustment is now required in next year’s forecast? (Note that you do not need to know the value of the forecast for next year in order to solve this problem.)Suppose the table below gives the average tuition and fees at 2-year and 4-year state schools in a particular state.
