Oregon legislative committee passes cap-and-trade bill Lawmakers are moving Oregon a step closer to adopting what would be the nation's second economywide carbon pricing scheme, after California. Source: Portland Business Journal, May 17, 2019- The transportation sector is Oregon's largest contributor to carbon emissions. Under what conditions would Oregon's carbon pricing scheme reduce carbon emissions to the efficient quantity? Use a graph to illustrate your explanation. Show the effects of setting the price of carbon too low and too high. GECED and The efficient quantity of transportation would be produced if the quantity of permits was set such that permits traded at a price A. marginal social cost of transportation equals marginal benefit; below marginal external cost OB. marginal private cost of transportation equals marginal benefit; above marginal external cost OC. carbon emissions were eliminated; equal to marginal benefit D. marginal social cost of transportation equals marginal benefit; equal to marginal external cost OE. marginal private cost of transportation equals marginal benefit; equal marginal external cost The graph shows the market for transportation in Oregon with no cap-and-trade system. On the graph, draw the marginal social cost curve of transportation. Label it. Draw a point to show the outcome of a cap-and-trade system that results in an efficient amount of emissions. Label it 1. Draw a point to show the outcome when the price of a permit is too low. Label it 2. Draw a point to show the outcome when the price of a permit is too high. Label it 3.
