Item Ecology and Valuation: Big Changes Needed(2007-09) Norton, Bryan G.; Noonan, Douglas S.Ecological Economics has developed as a “transdisciplinary science,” but it has not taken significant steps toward a truly integrated process of evaluating anthropogenic ecological change. The emerging dominance within ecological economics of the movement to monetize “ecological services,” when combined with the already well-entrenched dominance of contingent pricing as a means to evaluate impacts on amenities, has created a “monistic” approach to valuation studies. It is argued that this monistic approach to evaluating anthropogenic impacts is inconsistent with a sophisticated conception of ecology as a complex science that rests on shifting metaphors. An alternative, pluralistic and iterative approach to valuation of anthropogenic ecological change is proposed.Item A Quasi-Experimental Evaluation of High Emitter Non-Compliance and its Impact on Vehicular Tailpipe Emissions in Atlanta, 1997-2001(2006-01) Zia, Asim; Norton, Bryan G.; Noonan, Douglas S.; Rodgers, Michael O.; DeHart-Davis, LeishaA quasi-experimental evaluation is employed to assess the compliance behavior of high emitters in response to Atlanta’s Inspection and Maintenance program between 1997 and 2001 and to predict the impact of compliance behavior on vehicular tailpipe emissions of ozone precursors, such as carbon monoxide, hydrocarbons and nitrogen oxide. Remote sensing data of a sample of approximately 0.8 million observations of on-road vehicles are matched with IM program data and vehicle registration data to identify the compliant and non-compliant high emitters. A mixed-pool time-series regression analysis is carried out to predict changes in the vehicular tailpipe emissions due to the compliance and non-compliance of the high emitters in the Atlanta airshed.
