USA/China The two countries must cut greenhouse gas emissions to avoid the negative effects of climate change. Cutting emissions will necessarily reduce per capita GDP now and in the future. There are many ways that the sacrifice can be divided between the two countries. Your task will be to specify how the countries should share the substantial economic sacrifices that they need to make. Assume that the sacrifice has to be made: the question is of how it should be divided. CountryA/B On the border shared by the two countries lies a river. The two countries must build a dam on this river to avoid serious floods. Building the dam will reduce per capita GDP now and in the future. There are many ways that the sacrifice can be divided between the two countries. Your task will be to specify how the countries should share the substantial economic sacrifices that they need to make. Assume that the sacrifice has to be made: the question is of how it should be divided. FarmerA/B Uphill from the two farmers lies a stream. The two farmers must divert this stream to prevent it from running through their land, flooding their residences, and damaging their crops. Diverting the stream will cost a significant amount of money now and in the future, but will save their farms from very severe damage. There are many ways that the sacrifice can be divided between the two farmers. Your task will be to specify how the farmers should share the substantial economic sacrifices that they need to make. Assume that the sacrifice has to be made: the question is of how it should be divided. Figure 1: Graphical fairness elicitation. 2.1 Construction of Stylized Model of Rel￾ative Burdens Our goal in presenting per capita GDP for the U.S. and China both with and without the necessary sacrifices needed to combat climate change was not to develop a model that was as realistic as possible; nor was it to cap￾ture the underlying uncertainty that is unavoidable in such an endeavor. Rather, our goal was to create a simplified version of the problem that captured a few of its most
