b) An ecommerce firm plans to launch a new service. It estimates the demand curve as Qd=302P. The marginal cost of the product is zero. Assuming the firm is the only player in the market, what is the profit maximizing quantity and price? In order to launch the service, the firm estimates that it will need to incur a fixed cost between 100 and 150. What will be the profit if the fixed cost is 100? And if it is 150? What is the maximum fixed cost the firm will be willing to incur in order to launch its product? Now suppose fixed costs are zero, and the product successfully launched at the profit maximizing quantity and price. The government then steps in and imposes a price ceiling of P=$5. What is the new equilibrium? What is the change in profit compare to a). What is the change in consumer surplus? And the change in deadweight loss
