Four legal approaches may be followed in at-tempting to channel technological development
in socially useful directions: specific directives,
market incentive modifications, criminal prohi-
(5) bitions, and changes in decision-making struc-
tures. Specific directives involve the govern-
ment’s identifying one or more factors control-
ling research, development, or implementation
of a given technology. Directives affecting such
(10) factors may vary from administrative regulation
of private activity to government ownership of a
technological operation. Market incentive modi-
fications are deliberate alterations of the market
within which private decisions regarding the
(15)development and implementation of technology
are made. Such modifications may consist of
imposing taxes to cover the costs to society of a
given technology, granting subsidies to pay for
social benefits of a technology, creating the right
(20) to sue to prevent certain technological develop-
ment, or easing procedural rules to enable the
recovery of damages to compensate for harm
caused by destructive technological activity.
Criminal prohibitions may modify technological
(25) activity in areas impinging on fundament soc-
ial values, or they may modify human behavior
likely to result from technological applications—
for example, the deactivation of automotive
pollution control devices in order to improve
(30) vehicle performance. Alteration of decision-
making structures includes all possible modifica-
tions in the authority, constitution, or responsi-
bility of private and public entities deciding
questions of technological development and
(35) implementation. Such alterations include the
addition of public-interest members to corporate
boards, the imposition by statute of duties on
governmental decision-makers, and the exten-
sion of warranties in response to consumer
(40) action.
Effective use of these methods to control
technology depends on whether or not the goal
of regulation is the optimal allocation of
resources. When the object is optimal resource
(45) allocation, that combination of legal methods
should be used that most nearly yields the allo-
cation that would exist if there were no external
costs resulting from allocating resources through
market activity. There are external costs, when
(50) the price set by buyers and sellers of goods fails
历年GRE考试真题精选系列九
to include some costs to anyone, that resultfrom the production and use of the goods. Such
costs are internalized when buyers pay them.
Air pollution from motor vehicles imposes
(55) external costs on all those exposes to it, in the
form of soiling, materials damage, and disease,
these externalities result from failure to place a
price on air, thus making it a free good, com-
mon to all. Such externalities lead to nonopti-
(60) mal resource allocation, because the private net
product and the social net product of market
activity are not often identical. If all external-
ities were internalized, transactions would occur
until bargaining could no longer improve the
(65) situation, thus giving an optimal allocation of
resources at a given time.

rebated to purchasers of small automobiles, is
an example of
(A) a specific directive
(B) a market incentive modification
