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, common 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 externalities 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.
