- Question 2 (3.5 points) A firm produces a certain good. The current unit price of the good is equal to €7. At this price level, the marginal demand is equal to -0.8 and the point elasticity of demand is equal to -0.28. a. Give a precise economic interpretation of the number -0.8. b. Find the exact value of the current revenue of the firm and estimate the change in revenue if the current unit price is reduced by 3%. Next, assume that the demand is given by an equation of the form q = a/(bp). c. Find the values of the parameters a and b.
