### Core thesis
- Adaptation to climate change is a necessity for advanced and developing economies alike.
- Adaptation should be part of a holistic development strategy involving both private and public sector responses.
- Economic theory provides a useful framework to maximize the impact of public spending on adaptation.

### Key findings
- Governments can prioritize public investment in adaptation programs with positive externalities.
- Market imperfections and existing policies can make private adaptation inefficient; governments should address these failures.
- Cost-benefit analysis, complemented by analysis of distributional effects, can be used to prioritize adaptation programs alongside other development programs.
- Compensations may be needed to offset damages that are either impossible or too expensive to abate.
- Subsidies for adaptation require careful calibration to prevent excessive risk taking.

### Policy recommendations
- Prioritize public investment in adaptation programs that generate positive externalities.
- Correct market imperfections and reform policies that discourage efficient private adaptation.
- Mobilize revenues for adaptation and design mechanisms to distribute the benefits of adaptation equitably.
- Use cost-benefit analysis as the central tool for prioritizing adaptation and development programs, supplemented by explicit distributional analysis.
- Calibrate compensation and subsidy schemes carefully to avoid creating incentives for excessive risk taking.

### Analytical approach and tools
- Emphasizes use of economic theory to guide public spending decisions on adaptation.
- Recommends cost-benefit analysis as a primary prioritization tool.
- Advocates complementing efficiency analysis with distributional assessments to promote an efficient and just transition to a changed climate.
