| Summary: | Struck by the fact that economists did
not have a plausible model for why emissions standards, and
mandated technologies, play a dominant role in pollution
control, the author sought answers to two questions: 1)
Should one stimulate emissions reductions by firms, and
households, rich and poor, in the same way? 2) How should
one combine instruments that make activities cleaner, with
instruments that shift the economy toward less-polluting
activities? Using clean air as an example of a pure public
good, he shows the role of emissions taxes, or such
surrogate instruments, as emissions standards, and
presumptive Pigouvian taxes. To illustrate the combination
of demand management, and technical controls, he computes a
marginal cost curve for emissions reductions in the form of
cleaner cars, and fuels. And he estimates a demand model for
cars, and driving. The result: under the assumption that
revenue, and re-distributive transfers bear no premia, the
cost of reducing pollution in Mexico City increases forty
four percent if an emissions standards program is used, and
the presumptive Pigouvian tax on gasoline is not. The
important finding, as costly redistribution, and revenue
generation are introduced, is that this influences the
general scheme of taxation (in well-known ways), and it
influences the conditions for optimal environmental quality
in accordance with Pigou's conjecture. However, it does
not change, or invalidate the rankings of technologies, and
interventions on the control cost curve, nor does it change
the role of demand management in environmental protection. |
