Study Notes
Climate Change Policy Debate
- Economists Stern and Nordhaus disagree on climate action strategies
- Stern advocates for immediate high carbon tax
- Nordhaus favors gradual changes to avoid economic costs
- The core disagreement lies in the "discount rate"
- Stern supports a low discount rate, prioritizing future generations' needs
- Nordhaus favors a higher rate, emphasizing immediate economic returns
Ethical Debate on Intergenerational Justice
- Ethicists argue against discounting, emphasizing fairness to future generations
- They advocate for "intergenerational neutrality"
Positivist Argument for Discounting
- Positivists defend discounting, highlighting resource efficiency and market returns
- They argue for prioritizing investments that create wealth for future adaptation
Ethics vs. Efficiency
- Ethicists emphasize equitable distribution of resources across generations
- Positivists focus on efficient use of resources
Proposed Compromise
- Acknowledgement of ethical concerns alongside efficiency considerations
- Suggest increasing savings or adjusting investment strategies to benefit future generations without sacrificing immediate goals
Discounting and Intergenerational Impact
- Discounting determines the value of future benefits and costs compared to present ones
- Critics argue that discounting devalues the future
- Defenders argue that it's essential for assessing opportunity costs
Role of Opportunity Costs
- Discounting accounts for the opportunity cost of choosing climate actions over other investments
Long-Term Implications of Discounting
- High discount rates drastically reduce the importance of future damages
- Low discount rates value future impacts more, justifying more immediate action
Historical Debate
- Economists like Ramsey criticized discounting as ethically unsound
- Others argued that it could lead to excessive present sacrifices for uncertain future gains
Stern vs. Nordhaus
- Stern advocates for immediate action with a low discount rate
- Nordhaus recommends slower action with a high discount rate
The Positivist Position
- Market-based discounting reflects the market rate of return
- Compares returns on climate investments to alternative market investments
- Money vs. Welfare, future lives and welfare remain equally valuable
Challenges and Considerations for Positivists
- Private vs. Social Returns
- Uncertainty about discount rates over long horizons
- Future wealth and environmental valuation
The Ethical and Practical Divide
- Positivists emphasize economic efficiency, based on market returns
- Ethicists champion moral principles, believing future welfare should not be devalued
Intergenerational Equity and Ethical Obligations
- Ethicists champion equal treatment of future generations
- Value of future lives is equal to present ones
Endogenous Nature of Returns
- Investment return is not fixed but influenced by policies and actions on climate change
Concept of Social Discount Rate
- Social discount rate incorporates ethical judgments
- Considers economic growth and future wealth
Applying the Framework
- Hypothetical scenario illustrates alignment between ethical and economic approaches to climate solutions
Adjusting for Environmental Impact
- Identifying insufficient legacy (e.g., $70 instead of $100) requires adjustment
- Use market rate to choose high-return projects relative to cost
Market Rate and Savings
- Argument that increasing societal savings will drive market rates closer to an ethically motivated rate
Ethical Concerns and Intergenerational Equity
- Ethical concerns about environmental injustice (e.g., cost-benefit analysis failing to fairly represent future generations).
- Argument for intergenerational neutrality, suggesting future generations deserve a fair share of resources.
Opportunity Cost and Prioritization
- Argument that resource allocation should prioritize projects with high returns, maximizing resources.
- Ethical concerns should be considered when resource allocation is made considering long-term impacts.
The Ethicists' Challenge: Increased Savings Requirements
- Argument that drastically increasing savings to ensure just legacy might be practically difficult for governments and individuals.
Government Versus Individual Wealth Control
- The debate about whether government action is sufficient in ensuring that individuals do their part.
- Ricardian Equivalence highlights how individual actions can mitigate or diminish government efforts.
Feasibility and Intergenerational Transfer
- Practical challenges in guaranteeing that today's investments will benefit future generations.
- Potential for resource diversion by intervening generations.
