Abstract
This paper explores the impact of synthetic gypsum, a byproduct of sulfur dioxide (SO2) abatement, on the technical efficiency of SO2 scrubber technology. On average SO2 scrubbers are 60% efficient suggesting substantial emission reductions are possible by narrowing the efficiency gap. Gypsum marketability provides an economic incentive for improved power-plant operation of scrubbers with 8.8% average increases in technical efficiency. By contrast, we do not find any statistically significant evidence of innovative change in scrubbing technology.
期刊介绍：
Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
