Answer to Question 2
It is highly desirable that gross profit margin would be stable for all firms, but it is unlikely that this would occur in all industries. As cost of goods sold increases for a firm, the firm will raise selling prices to maintain a stable gross profit margin; however, in some industries the competition is such that this is not possible. Grocery stores and retailers tend to have stable gross profit margins, but high technology firms tend to have volatile gross profit margins from year to year.
