Do you think that farmers collectively would try to reduce the supply of wheat and drive the price up 2 higher per bushel? Explain your answer. Assuming that they would try to reduce supply, what problems might they have in actually doing so?arrow_forwardSuppose you are in change of sales at a pharmaceutical company, and your firm has a new drug that causes bald men to grow hair. Assume that the company wants to earn as much revenue as possible from this drug. If the elasticity of demand for your companys 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?

- (Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?arrow_forwardAssume that a decrease of 10 percent in the price of cars results in an increase of 30 percent in quantity demanded, then the price elasticity of demand is 3 O 0.5 O 1 O 0.333arrow_forwardAn end-of-aisle price promotion changes the price elasticity of a good from -4 to -5. Suppose the normal price is $48, which equates marginal revenue with marginal cost at the initial elasticity of -4. What should the promotional price be when the elasticity changes to -5?
