The purpose of our contribution is twofold. It proposes a combined ecological-economic model that captures the link between the economy and the ecosystem in a more inclusive way than standard economic optimization models do. This is done in order to demonstrate the non-triviality of finding a policy mix that leads to a sustainable path of the coupled system.
To enable this analysis, the model has three characteristics distinguishing it from traditional environmental and resource economic models: (1) it implements a multi-dimensional link between the economic and the ecological system, considering side effects of production, and thus combines the analyses of environmental and resource economics; (2) following authors from biology it uses a difference equation approach for the biological resource instead of the typical differential equation, allowing for the whole range of stability regimes by means of a single equation, and (3) it links this resource system to an evolving, agent-based industry (on the basis of a Nelson-Winter model) instead of the standard optimization model.
Main results are that (1) in face of multiple influences of the industry on nature, the selection and calibration of policy instruments is highly important to avoid or minimize trade-offs between sustainability dimensions and (2) the most obvious political instrument in case of overexploitation, and the only working as a single instrument, should, surprisingly, be left out of a policy mix for sustainable development.
