Please note that in answering economics questions it is important to first identify which part of economic theory you should be drawing on in order to respond appropriately. Your response should always be firstly identifying what part of theory the question relates to and explaining that theory, how the theory helps to answer the question and then presenting the solution to the question poised.

Question 1. Suppose you are in charge of sales at a pharmaceutical company, and your firm has a new drug that causes bald men to grow hair.

If the elasticity of demand for your company’s product at the current price is 1.4, would you advise the company to raise the price, lower the price, or to keep the price the same? What if the elasticity were 0.6? What if it were 1? Explain your answer.
