This paper compares the optimal dynamic choices between policies of mitigation and adaptation for three economies: Brazil, Chile and the United States. The focus is on the optimal role of mitigation and adaptation for “environmentally small economies,” i.e., economies that are witnessing an exogenous increase in emissions to which they are contributing very little. The simulations lead to three main conclusions. First, small economies should concentrate their environmental efforts, if any, on adaptation. This is not a recommendation that such economies indulge in free-riding. Instead, it is based on considerations of cost effectiveness, ceteris paribus. Second, small economies that are unable to spend enough on adaptation may end up spending less on mitigation owing to their impoverishment as a result of negative climate shocks. Third, higher mitigation expenditures may arise not only as a result of greater optimal adaptation expenditures, but also because of increased adaptation to the incentives for mitigation provided by richer countries.
The overall purpose of this study is to analyze the synergies of environmental mitigation initiatives in practice, based on the approach proposed by Muller and Mendelsohn (2011). According to this methodology, externalities associated with local pollutants are measured using the impact pathway approach. The main local benefits to be derived from applying mitigation measures are the impacts on heal ... (View publication)
This issue of IDEA covers some of the IDB’s recent research on climate change, including efforts on both the mitigation and adaptation fronts. That research includes both surprising findings and an underlying understanding that the region’s development must take into account -and will in many ways be shaped by- how it deals with this unique and inescapable issue.

The general objective of this study is to review the international literature and best practices to develop a methodological framework capable of quantifying the increase in investments necessary for a traditional standard of living in a world subject to climate change. This methodology is then applied to two case studies: Bolivia and Chile. In particular, the document addresses the economics of a ... (View publication)
