A GAME-THEORETIC TREATMENT OF A TIME-DISCRETE EMISSION REDUCTION MODEL

摘要

We present a game-theoretic treatment of the so-called TEM model which leads to new results in the area of time-discrete dynamical games. The presented TEM-model describes the economical interaction between several actors (players) who intend to minimize their emissions (E_i) caused by technologies (T_i) by means of expenditures of money (M_i) or financial means, respectively. The index stands for the ith player, i = 1,...,n. The players are linked by technical cooperations and the market, which expresses itself in the nonlinear time-discrete dynamics of the Technology-Emissions-Means-model, in short: TEM-model. In the sense of environmental protection, the aim is to reach a state which is mentioned in the Kyoto Protocol by choosing the control parameters such that the emissions of each player become minimized. The focal point is the realization of the necessary optimal control parameters via a played cost game, which is determined by the way of cooperation of the actors. In application to the work of G. Leitmann [1974], but not regarding solution sets as feasible sets, the τ-value of S. H. Tijs and T. S. H. Driessen [1986] is taken as a control parameter. This leads to a new class of problems in the area of 1-convex games. We want to solve the problem by a non-cooperative and cooperative treatment. We prove that the core which is gained by cooperation of the players is nonempty and can be used as feasible set for our control problem. With this solution a reasonable model for a Joint-Implementation process is developed, where its necessary fund is represented by the non-empty core of the analyzed game. Steering with parameters of this feasible set, the TEM-model can be regarded as a useful tool to implement and verify a technical Joint-Implementation Program. For the necessary data given to the Clearing House (http://www.unfccc.org/ resource/convkp.html) we are able to compare the numerical results with real world phenomena.
