The production Compact Fluorescent Lightbulbs (CFL) use mercury in their production process. Mercury is a heavy metal and considered bad for the environment. Suppose the marginal external cost is $5 per lightbulb and the government levies a corrective tax of $5.50 per lightbulb. With this new tax: Selected answer will be automatically saved.

Fish that swim in international waters are a common good that are freely available toanyone who wants to catch them, but this leads to the problem of over-fishing.

A local school administrator observes an increase in the number of flu cases in the public schools over the last two years. She is concerned that some families cannot afford flu vaccine and are therefore not having children vaccinated. She is also concerned that the failure to vaccinate some children is putting other children at risk, so she proposes that the state subsidize vaccines to increase coverage rates. a. Determine whether the failure to vaccinate some children is an external benefit or an external cost. If an external cost is present, move point A and point B to show the marginal social cost curve. If an external benefit is present, move point A and point B to show the marginal social benefit curve. Place point C at the equilibrium outcome. Place point D at the socially optimal outcome. Flu vaccines A B D Supply (marginal private cost) Price

What is an external benefit? An external benefit is a benefit that OA. always equals external cost OB. experiences increasing marginal returns C. affects someone other than the buyer of a good OD. is greatest at the equilibrium point
