| Tiivistelmä: | Human well-being depends to a large extent on services provided by ecological systems. In poor countries, this dependence is more transparent than in industrialized countries. Effective management of these systems requires good understanding of their properties and particularly knowledge of the dynamics of the systems. In this article, the dynamics of one "simple" system is analyzed economically. It turns out that the dynamics exhibit bifurcation points so that there are 2 basins of attraction. If the system flips to one basin and it is regarded desirable to return to the other basin, there will be hysteresis. Assuming that there are different users of the lake, a differential game is constructed that captures the strategic interests of the users. The resulting equilibrium shows first the conventional negative externality that will force the system to a different basin od attraction. Finally, the use of tax is investigated for bringing back the system to Pareto optimum. |
