The graph illustrates the unregulated market for uranium When the mines produce uranium, they also create waste which they dump into a river that runs through a small town The marginal external cost of the dumped waste is equal to the marginal private cost of producing uranium (that is, the marginal social cost of producing the uranium is double the marginal private cost) If no one owns the river and the government levies a pollution tax, what is the tax per ton of uranium that achieves the efficient outcome? Draw a point to show marginal social cost if production is 240 tons Draw the MSC curve and label it Draw an arrow at the efficient quantity that shows the marginal external cost. The tax per ton of uranium that achieves the efficient outcome is $|: Price and cost (dollars per ton) Q 0 60 120 180 240 300 Quantity (lons per week) >>> Draw only the objects specified in the
