Suppose a basket of goods and services has been selected to calculate the cpi and 2012 has been selected as the base year. in 2012, the basket's cost was $77; in 2013, the basket's cost was $82; and in 2014, the basket's cost was $90. the value of the cpi in 2014 was 109.8 and the inflation rate was 16.9%. 116.9 and the inflation rate was 9.8%. 109.8 and the inflation rate was 9.8%. 116.9 and the inflation rate was 16.9%

4. understanding different policy options to correct for negative externalities carbon dioxide emissions have been linked to global warming. the following table lists some possible public policies aimed at reducing the amount of carbon dioxide in the air. for each policy listed, identify whether it is a command-and-control policy (regulation), tradable permit system, corrective subsidy, or corrective tax. public policy command-and-control policy tradable permit system corrective subsidy corrective tax the government charges factories $110 for every ton of carbon dioxide they emit. the government orders every factory to adopt a new technology, which reduces carbon-dioxide emissions into the atmosphere. trees take carbon dioxide out of the air and convert it to oxygen, so the government funds a tree-planting initiative by offering $110 to any citizen who plants a tree. the government limits total carbon-dioxide emissions by all factories to 180,000 tons per month. each individual factory is given the right to emit 140 tons of carbon dioxide, and factories may buy and sell these rights in a marketplace.
