Suppose Hawi lives alone. She has two pet hamsters; she likes the hamsters because they are cute.  But cleaning their cage every day is a hassle. In this case, Hawi's hamsters entail: A. an external cost B. a negative externality C. an external benefit D. neither an external cost nor an external benefit

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. For keyboard navigation, press up/down arrow keys to select an answer. a b Question 4 с d The price will be below the marginal social cost. Not enough light bulbs will be produced. The price will be below the marginal social benefit. The price will be below the marginal cost to produce light bulbs.

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. At theheart of this problem lies an externality. Using appropriate diagrams andaccompanying discussion, show both how and why this over-fishing takes place. Inyour explanation, identify the source of the externality.

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

Externalities Do you think that there would be external effects associated with Water from a uranium mine leaking into Kakadu National Park? If so, what would be the nature of the external effects? Can you think of policies that might deal with each external effect (that is, improve social wellbeing)?

38. Negative externalities are also called a. positive externalities. b. external benefits. c. external costs.

Mankiw Chapter 11 2 b Are the externalities associated with common resources generally positive or negative? Use examples in your answer. Is the free market use of common resources generally greater or less than the efficient use?

Suppose Scott and Bob live on the same street. in the winter, both of them like their street plowed. Bob's demand is given by 0 = 40 - P, and Scott's demand is gren by 0 = 30 - 2P. Suppose the marginal cost of plowing the snow is constant at $35 (a) What is the social marginal benefit curve? (b) What is the socially efficient amount of plowing? (c) What would be the socially efficient amount of plowing if the marginal cost of plowing were $5?
