Abstract
Acid deposition has become a serious environmental problem in the last decade. The economic repercussions of acid deposition control regulations give rise to interregional and international conflicts as to who is to bear the burden of its abatement. Responsive policy decisions have to be based on models that take into account the most important concerns of policy makers.
In this study, an integrated economic-environmental-policy model has been proposed for use at the interregional level of analysis. A system of regions is assumed and the model's output refers to annual economic and environmental magnitudes. The model consists of four interlinked modules: an economic, an environmental, a cost, and a decision-making module. Exogenous forecasts from other regional and/or national economic models as well as scientific information are fed into the model. The main emphasis is on the linkages of the modules so that an integrated analysis can be performed with the model.
The economic module consists of an interregional input-output model. The environmental module includes three models accounting for pollutants (sulfur dioxide and sulfate, in the present case) transport, transformation, deposition, and subsequent ecosystem acidification. The cost module includes an abatement cost and a damage cost model for the system of regions. The decision-making module consists of a set of regional profiles for each region and an optimization model.
The model can be used to test alternative sulfur dioxide emissions reduction schemes (or, distributions) for the system of regions. Economic and environmental impacts are identified, evaluated and, possibly, used to modify the initially tested scheme.
Another use of the model is the generation of sulfur dioxide emissions reduction schemes once the desired levels of regional economic outputs and acid deposition for each region are specified.
An illustrative example of the use of some parts of the model complements the theoretical part of the study. A sensitivity analysis, using 16 scenario cases, was performed on the model. However, no conclusions could be drawn from this example given its hypothetical nature and its small size.
Finally, the study pointed to future research needs and directions for the refinement of the proposed model.
