The Last Word is about carbon dioxide emissions and different ways governments have tried to deal with air pollution.

Market Failures Market failures Markets fail to produce the right amount of the product Resources may be Over-allocated Under-allocated LO1 Market failure occurs when the competitive market system produces the “wrong” amounts of certain goods or services, or fails to provide any at all. Resources are either over-allocated to the production of the good or under-allocated to the production of the good. Demand-Side Market Failures Demand-side market failures When it is not possible to charge consumers for the product Some can enjoy benefits without paying Firms not willing to produce since they cannot cover the costs LO1 Demand-side market failures occur because there are situations when it is impossible to charge all consumers, or any consumers, the price that they are willing to pay. A public fireworks display is an example where people don’t have to pay to enjoy the display. Private firms would be unwilling to produce outdoor displays as it will be impossible to raise enough revenue to cover production costs. Firm can’t prevent people from watching the fireworks if they didn’t pay. .
