2. Global evidence on the income elasticity of willingness to pay, relative price changes and public natural capital values

Abstract

While the global economy continues to grow, ecosystem services tend to stagnate or decline. Economic theory has shown how such shifts in relative scarcities can be reflected in project appraisal and accounting, but empirical evidence has been sparse to put theory into practice. To estimate relative price changes in ecosystem services to be used for making such adjustments, we perform a global meta-analysis of contingent valuation studies to derive income elasticities of marginal willingness to pay (WTP) for ecosystem services to proxy the degree of limited substitutability. Based on 735 income-WTP pairs from 396 studies, we find an income elasticity of WTP of around 0.6. Combined with good-specific growth rates, we estimate relative price change of ecosystem services of around 1.7 percent per year. In an application to natural capital valuation of forest ecosystem services by the World Bank, we show that natural capital should be uplifted by around 40 percent. Our assessment of aggregate public natural capital yields a larger value adjustment of between 58 and 97 percent, depending on the discount rate. We discuss implications for policy appraisal and for estimates of natural capital in comprehensive wealth accounts.

3. Testing the free-rider hypothesis in climate policy

Abstract

Free-riding is widely perceived as a key obstacle for effective climate policy. In the game-theoretic literature on non-cooperative climate policy and on climate cooperation, the free-rider hypothesis is ubiquitous. Yet, the free-rider hypothesis has not been tested empirically in the climate policy context. With the help of a theoretical model, we demonstrate that if free-riding were the main driver of lax climate policies around the globe, then there should be a pronounced country-size effect: Countries with a larger share of the world's population should, all else equal, internalize more climate damages and thus set higher carbon prices. We use this theoretical prediction for testing the free-rider hypothesis empirically. Drawing on data on emission-weighted carbon prices from 2020, while controlling for a host of other potential explanatory variables of carbon pricing, we find that the free-rider hypothesis cannot be supported empirically, based on the criterion that we propose. Hence, other issues may be more important for explaining climate policy stringency or the lack thereof in many countries.

Abstract

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Abstract

Governments are catching up with economic theory and practice by increasingly integrating ecosystem service values into national planning processes, including benefit-cost analyses of public policies. Such analyses require information not only about today’s benefits from ecosystem services but also on how benefits change over time. We address a key limitation of existing policy guidance, which assumes that benefits from ecosystem services remain unchanged. We provide a practical rule that is grounded in economic theory and evidence-based as a guideline for how benefits change over time: They rise as societies get richer and even more so when ecosystem services are declining. Our proposal will correct a substantial downward bias in currently used estimates of future ecosystem service values. This will help governments to reflect the importance of ecosystems more accurately in benefit-cost analyses and policy decisions they inform.

Abstract

Mitigating greenhouse gas emissions and reducing air pollution represent two pressing and interwoven environmental challenges. While international carbon markets, such as the European Union emissions trading system (EU ETS), have demonstrated their effectiveness in curbing carbon emissions (CO2), their indirect impact on hazardous copollutants remains understudied. This study investigates how key toxic air pollutants--sulfur dioxide (SO2), fine particulate matter (PM2.5), and nitrogen oxides (NOx)-- evolved after the introduction of the EU ETS with a comparative analysis of regulated and unregulated sectors. Leveraging the generalized synthetic control method, we offer an ex post analysis of how the EU ETS and concurrent emission standards may have jointly generated sizable pollution reductions in regulated sectors between 2005 and 2021. We provide an aggregate assessment that these pollution reductions could translate into large health co-benefits, potentially in the hundreds of billions of Euros, even when bounding the effect of emission standards. These order-of-magnitude estimates underscore key implications for policy appraisal and motivate further microlevel research around the health co-benefits of carbon abatement. [ABSTRACT FROM AUTHOR]

30. Philosophers and economists agree on climate policy paths but for different reasons

Author

Abstract

The estimated value to society from climate change mitigation is highly sensitive to the long-term social discount rate. Governmental discounting guidance has almost exclusively been influenced by economists, although it is not clear that they possess any special expertise on intergenerational ethics. Here, by contrast, we report the views of philosophers, who are the most trained in ethical matters. We show that, as a group, these experts offer strong support for a real social discount rate of 2%, a value that is also predominantly backed by economists. We find multidisciplinary support for climate policy paths in line with the United Nations climate targets when views on discounting determinants are applied within a recent update of the DICE integrated assessment model. However, this apparent agreement hides important differences in views on how the ethics of intergenerational welfare can be better incorporated into climate policy evaluation.

Abstract

We study how background health risk affects financial risk-taking. We elicit financial risk-taking behavior of a representative sample of more than 5,000 Germans in five panel waves during the COVID-19 pandemic. Exploiting variation in local infections across time and space, we find that an increase in infections affecting background health risk translates into higher levels of self-reported fear and decreases financial investments in a risky asset. Once vaccines become available as a self-insurance device, the tempering effect on investments ceases. Our results provide evidence that non-financial background risks affect financial risk-taking, and for the alleviating effect of self-insurance devices.

42. The future, now:A review of social discounting

Author

Abstract

Governments across the world are coming under increasing pressure to invest heavily in projects that have maturities of decades or even centuries. Key areas of concern include climate change mitigation, environmental and biodiversity protection, nuclear decommissioning, enhancing infrastructure and coastal defenses, and long-term health care management. Whether such projects are evaluated as being economically justifiable depends on the social discount rate (SDR) that the government deploys. This variable converts the future costs and benefits of public policy into their value today, thereby facilitating the comparison of social investments with different maturities. Critically, the result of such analysis is extremely sensitive to small changes in the choice of the SDR, yet policy guidelines differ widely across countries and international institutions. In this article, we provide a review of the academic literature on long-term SDRs, with particular emphasis on how these insights have been integrated into governmental guidance.

43. Climate Policy Curves: Linking Policy Choices to Climate Outcomes

Abstract

The extent of future climate change is a policy choice. Using an integrated climate-economy assessment model, we estimate climate policy curves (CPCs) that link the price of carbon dioxide (CO2) to subsequent global temperatures. The resulting downward sloping CPCs quantify the inverse relationship between carbon prices and future temperatures and illustrate how climate policy choices determine climate outcomes. Our analysis can account for a variety of climate policies – for example, carbon or fuel taxes, emissions trading programs, green subsidies, and energy-efficiency regulations – all of which can be summarized by means of an effective CO2 price. Importantly, we also examine CPC uncertainty, for example, by perturbing the model's equilibrium climate sensitivity to trace out the temperature range associated with a given CO2 price. Finally, based on the latest Intergovernmental Panel on Climate Change (IPCC) integrated-assessment model scenarios, we estimate an implicit CPC, which provides a high-level IPCC summary of the climate policy actions required to achieve global climate targets.

Abstract

We study the variation of global and unilateral carbon price recommendations and their determinants. To this end, we provide survey evidence on carbon pricing from more than 400 experts across almost 40 countries. We quantify the extent of (dis-)agreement and reveal that a majority of experts can agree on some short- and medium-term global carbon price levels, and on unilateral carbon price levels in most countries. We find little evidence for free-riding. Indeed, experts' unilateral carbon price recommendations with border carbon adjustment are, on average, higher than global recommendations. Furthermore, border carbon adjustment facilitates higher price recommendations and tends to foster agreement among experts on carbon price levels. We analyze how experts' recommendations vary with additional survey data on key policy design issues, such as instrument choice, other likely determinants of carbon price recommendations as well as country characteristics and observable expert characteristics.

46. Philosophers and Economists Can Agree on the Intergenerational Discount Rate and Climate Policy Paths

Abstract

The estimated values to society from long-term public projects, including climate change mitigation and infrastructure construction, are highly sensitive to the social discount rate (SDR) employed. Governmental guidance on social discounting has predominantly been based on input from expert economists. It is not clear, however, that economists possess any special expertise on the ethical issues that underpin long-term societal decision-making. This study compares expert economists' views on key components of the long-term SDR with those of a disciplinary group of experts who may be deemed most trained on ethical matters: philosophers. The results indicate that both expert groups provide surprisingly similar recommendations on these components and on the SDR itself, with a real SDR recommendation of 2% receiving most support in both disciplines. An analysis of qualitative remarks shows areas of broad agreement and yet distinct differences in rationales. While economists provide numerous technical extensions within a consequentialist Discounted Utilitarian approach, philosophers advocate more strongly for alternative ethical approaches to standard Utilitarian calculus. In the politicized world of long-term decision-making, this paper illustrates how more inclusive and deliberative approaches to complex issues such as intergenerational justice can guide more nuanced decision-making today and lead to multidisciplinary support for climate action.
