“…14 13 The tradeo¤, in our damage function, between the levels of emission, E; and adaptation, a i ; is similar to that in the literature on multiple pollutants in the context of climate change, where some pollutants such as CO 2 increase global warming and others such as SO 2 have a cooling e¤ect (see, for example, Legras and Zaccour, 2011). 14 In our model, the net cost of adaptation is given by the cost function, C (a i ) ; less the bene…t from adaptation in terms of reduced damage, a i E: Thus, our net cost of adaptation is decreasing in the global emission level, E; for all > 0.…”
