Research into the soft drink market indicates that the two firms compete by selecting quantities (Cournot competition). Soft drinks are regarded as a homogeneous good by consumers. and inverse demand in the market is estimated to be, i l' where F' represents the price of a bottle of soft drink, and Q is the total number of bottles sold per year. At present soft drinks sell for $2.95 a bottle. Bubbles F'LC produces 4D,Di} bottles per year. paying $l.[l in bottle tax. CarbonCorp produces 25,[l[l bottles and pays $l.. It is estimated that it costs Bubbles PLC $2.15 per bottle of soft drink produced. while producing a bottle of soft drink cost CarbonCorp $2.3D. The fixed costs of production can be neglected in this analysis. P=3.6 2 Scenario The island nation of Autarka is growing concerned over the amount of rubbish accumulating in the waters off its coastline. This pollution is harming marine life, damaging fish stocks, and washing up on tourist beaches. Research by the National University of Autarka has determined that a significant component of the solid waste is the singleuse plastic bottles used by softdrink manufacturers. Currently. soft drink manufacturers in Autarka pay a tax of $0.40 on each bottle of drink they sell. The revenue from the tax is used to fund the cleaning of roads and public spaces. The scientific community is lobbying the government to increase the tax to $1.00 a bottle. The scientists suggest that any additional revenue could be used to fund programs to remove rubbish from the coastal waters. There are two producers of soft drinks in Autarka: Bubbles PLC and CarbonCorp. The two companies do not face competition from imports as the cost of transporting soft drinks into Autarka is prohibitively high. Moreover. there are no cost effective alterna tives to single use plastic containers. The two companies have made submissions to the government opposing the proposed tax increase, which they claim will harm consumers. 3.1 Required steps When completing the industry analysis you should assume that firms are engaged in Cournot Competition. Step 1: Using the information provided in the scenario. derive a total cost function for each soft drink producer for the case in which the government levies a tax of $1.00 per bottle. Use OS to denote the quantity produced by Bubbles PLC, and Q; to denote the quantity produced by lCarhonCorp. Note that a firm's marginal cost will he the sum of its cost of producing a bottle. and the tax that it must pay to the government on each bottle sold
