4. Understanding different policy options to correct for negativeexternalities Carbon dioxide emissions have been linked to melting of sea ice. The following table lists some potential regulations targeting the amount of airborne carbon dioxide. For each policy listed, identify whether it is a command-and-control policy (regulation), tradable permit system, corrective subsidy, or corrective tax. Tradable Command-and- Permit Corrective Corrective Public Policy Control Policy System Subsidy Tax The government orders every factory to adopt a new technology, which O O reduces carbon-dioxide emissions into the atmosphere. The government charges factories $500 for every ton of carbon dioxide O O O O they emit. The government agrees to reimburse all factories that purchase new, O O O O emissions-reducing technology in order to provide cleaner air. The government limits total carbon-dioxide emissions by all factories to 250,000 tons per five years. Each individual factory is given the right to O O O O emit 280 tons of carbon dioxide, and factories may buy and sell these rights in a marketplace
