effect.

b.they have incentives to increase production above the monopoly outcome.
c.they do not behave as profit maximizers.
d.self-interest juxtaposes the profits earned at the Nash equilibrium.
6) Which of the following is an example of a barrier to entry?

of producers.

9) Figure 10-18. The graph represents a corrective tax to reduce pollution. On the axes,

b.is viewed by most economists as less effective than a command-and-control policy as
a means of reducing pollution.
c.has the effect of moving the allocation of resources further from the social optimum
than it would be in the absence of the tax.
