A proposed irrigation project would lower the constant marginal cost of producing rice from $1,000 to $600 per unit. The local market for rice is competitive and has a demand curve given by Q^D = 7,500 − 0.5P where P is the price. Draw a graph of the supply and demand for rice to show the change in consumer surplus due to the irrigation project. Calculate the increase in the net benefits to consumers. If the irrigation project will cost taxpayers $28.1 million, is it worth undertaking?
