Q2. [30 marks] Consider the following simple model. Suppose that the research and development cost of a new vaccine is equal to $15. A company X is considering investing in developing this vaccine. The demand for the nal product is given by P=l{}-Q, where P is the price of one vaccine dose and Q is the quantityr demanded. The marginal cost of producing one dose of vaccine is constant tie it does not depend on the output level) and is equal to $2. Let's assume for simplicity that the vaccine production process does not involve any xed cost. This implies that the average total cost is also constant and equal to $2
