Each country has two possible strategies for addressing global carbon emissions: Restrict (taking measures to reduce emissions, for example by taxing the use of fossil fuels) and BAU (the Stern report's business as usual scenario). Figure 4.17 describes the outcomes (top) and hypothetical payoffs (bottom), on a scale from best, through good and bad, to worst. This is called an ordinal scale (because all that matters is the order: whether one outcome is better than the other, and not by how much it is better). 1. Show that both countries have a dominant strategy. Which ofthe four quadrants in the below table is the outcome of the game (Nash Equilibrium)? Why? . The outcome would be better for both countries if they could negotiate a binding treaty to restrict emissions. Why might it be difcult to achieve this?
