Pollution control innovations and the Clean Air Act of 1990

Popp, David·2003·Journal of Policy Analysis and Management

Abstract

One advantage often cited for market‐based environmental policies is that they are more likely to promote technological innovation than are command and control regulations. This paper uses patent data to study innovation in flue gas desulfurization units (“scrubbers”) across these policy regimes. Plant level data indicate that the effect of these patents on pollution control changed after passage of the 1990 Clean Air Act, which instituted a market for sulfur dioxide (SO 2) permits. Previous regulations requiring plants constructed before 1990 to install scrubbers created incentives for innovation that lowered the costs of operating scrubbers, but did little to improve the environmental effectiveness of the technology. In comparison, innovations occurring since 1990 do serve to improve the removal efficiency of scrubbers. © 2003 by the Association for Public Policy Analysis and Management.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
