A Multilevel, Multiobjective Policy Model: The Case of Marine Aquaculture Development

Marine aquaculture development is often constrained due to the difficulty in accommodating the industry within the evolving framework of coastal zone regulatory policy. One contributing problem is the dearth of socioeconomic, environmental, and institutional knowledge. To address this issue, a dynamic multiobjective, multilevel policy model is formulated for net-pen aquaculture development using effluent taxes as a policy instrument. Dynamic policy frontiers are generated by solving the aquacultural sector's problem, embedding the producer's dynamic response within the policy maker's problem, and then parameterizing on policy goals. The frontiers represent economic policy information consistent with the needs of a policy bargaining process. Copyright 1996, Oxford University Press.
