The basic cause of deadweight losses from the existence of common resources and
externalities is
A) a lack of clearly defined and enforceable property rights.
B) the self-interested rationality of human beings.
C) the use of a market system to deal with scarcity.
D) the absence of government intervention.
Figure 5-5 Figure 5-5 shows a
market with an externality. The current market equilibrium output of Q1 is not the
economically efficient output. The economically efficient output is Q2.
If, because of an externality, the economically efficient output is Q2 and not the current
equilibrium output of Q1, what does D1 represent?
A) the demand curve reflecting external benefits
B) the demand curve reflecting social benefits
C) the demand curve reflecting private benefits
D) the demand curve reflecting the sum of private and social benefits
