In this paper we test empirically with the Nordhaus and Yang (1996) RICE model the core property of the transfer scheme advocated by Germain, Toint and Tulkens (1997). This scheme is designed to sustain full cooperation in a voluntary international envir- onmental agreement by making all countries at least as well o as they would be by joining coalitions adopting emission abatement policies that maximize their coalition payo ; under the scheme no individual country, nor any subset of countries would have an interest in leaving the international environmental agreement. The simula- tions show that the transfer scheme yields an allocation in the core of the carbon emission abatement game associated with the RICE model. Finally, we discuss some practical implications of the transfer scheme for current climate negotiations.
