Cost effective analysis in health care (Nursing) Naveen J HNaveen j h
Cost-effective analysis (CEA) is used to identify the most cost-effective way to achieve social and health goals when directly quantifying benefits in monetary terms is difficult. CEA calculates a cost-effectiveness ratio by dividing total costs by units of effectiveness. For example, comparing the costs and patient outcomes of different medical diagnostic machines. While one machine costs less per diagnosis, a more expensive machine could diagnose many more patients. CEA is applied in the document to compare costs and outcomes of different wound care and antenatal visit approaches. CEA seeks the best alternative to minimize resource use and achieve desired results.
Risk-based Regulation: OECD Best Practice Principles, Nick MalyshevOECD Governance
This document discusses risk-based regulation principles from an OECD conference. It defines risk as the probability and impact of an event. It notes that while some risks like accidents and pollution are decreasing over time, public concern about risks continues to grow. Governments are accountable for costs of both regulation and failure to prevent risks. Effective risk regulation involves prioritizing risks, risk assessment, considering risk-risk tradeoffs, and learning from other countries. Examples shown include risk matrices that determine inspection frequency based on sector risk and a business's history. Data suggests targeted, risk-based inspections can significantly reduce inspection burdens with no loss of outcomes.

Combined effects of global climate change and toxicants are complex and can be exacerbated or compensated for at higher levels of biological organization. The study discusses 4 ecological mechanisms using 3 case studies: 1) Demographic processes can compensate or propagate individual impacts to population levels. 2) Climate change can reduce resistance and recovery from toxicants at population and community levels. 3) Acquired tolerance to stressors often comes at a cost of reduced genetic diversity and increased susceptibility. 4) Species vulnerability is influenced by traits and landscape changes from climate change altering toxicant exposures. Long-term experiments incorporating realistic climate projections are needed to make reliable predictions.
A hazard is something that can cause harm, while a risk is the chance that a hazard will cause harm. Environmental risk assessment is the process of estimating potential impacts of hazards like chemicals or climate change on human health. It involves compiling exposure data, reviewing epidemiological evidence on associations between environmental factors and health, and combining exposure and response data. Key steps include specifying the health risk and exposure measures, estimating population exposure, selecting health outcomes and exposure-response relationships, and calculating attributable burdens of disease.
The document discusses environmental risk assessment and management. It defines key terms like risk, environmental risk assessment, and risk characterization. It outlines the steps in risk assessment as hazard identification, dose-response assessment, exposure assessment, and risk characterization. It also discusses grading of risk from low to high. The steps in risk management are identified as risk assessment, technological feasibility assessment, economic impact analysis, consideration of public concerns and legal requirements, decision making, implementation, monitoring and evaluation, and review. Risk management aims to prevent adverse effects on human health and ecological systems.
Risk Assessment and Environment Managementtabirsir
Comparative risk assessment is used to set environmental management priorities by identifying and evaluating multiple risks. It involves four phases: planning, data collection and analysis to estimate risks, priority setting through risk comparison and debate, and reporting to inform risk management. Health risk assessment is a type of risk assessment that specifically evaluates potential public health impacts through steps like hazard identification, dose-response assessment, exposure assessment, and risk characterization. Examples provided assessed health risks from air pollution in Bangkok and pesticide exposure through food in Quito, Ecuador.
This document discusses human health risk assessment. It defines risk assessment as having two main types - quantitative risk assessment and environmental risk assessment. Environmental risk assessment includes human health risk assessment, where risk is defined as hazard times exposure. The document outlines the process of human health risk assessment, including determining exposure through intake calculations, establishing toxicity values from animal studies with uncertainty factors, and characterizing risk for carcinogenic and non-carcinogenic chemicals by calculating hazard quotients and risk levels. The goal of risk assessment is to properly assess and manage risks to avoid health effects.
This document discusses different types of economic evaluations used to analyze health interventions, including cost-minimization analysis, cost-effectiveness analysis, and cost-utility analysis. It provides examples and steps for conducting cost-effectiveness analysis to compare interventions and allocate resources. The document explains how to calculate cost-effectiveness ratios, incremental cost-effectiveness ratios, and use rules like dominance and extended dominance to identify the most cost-effective interventions within a given budget.

Exploring Deep Savings: A Toolkit for Assessing Behavior-Based Energy Interve...Beth Karlin
While research assessing behavior-based energy interventions shows great promise, results vary widely and much is still unknown about the specific variables that impact program effectiveness. As utilities and regulatory agencies focus more attention on behavior-based energy interventions, it becomes critical to ensure that evaluations of such programs are rigorous and accurate. While the metric used to measure whether these various programs work (kWh) is fairly standard and easy to compare between studies, the metrics used to measure how and for whom they work have been left to individual researchers and evaluators. Standardization of assessment methods is common in related fields such as education and psychology, but has yet to take hold in energy program evaluation. This paper argues for a more systematic and comprehensive approach to the evaluation of behavior-based energy interventions, and describes a preliminary toolkit that is currently being developed and validated in conjunction with the International Energy Agency Demand Side Management Programme (IEA-DSM) Task 24 on Behavior Change as well as two large investor-owned utilities. Our approach is informed by theories and empirical research on behavior change as well as a content analysis of 85 behavior-based energy interventions. It includes questions on: context (demographics), user experience (ease of use, engagement), material culture (what people have), energy practices (what people do), and beliefs around energy use (what people think). Sample items for each construct and suggestions for implementation are presented. Broad use of such an instrument can improve and aggregate our overall knowledge across the countless additional studies expected to be conducted in the coming years.
This document discusses environmental risk assessment (ERA). It defines ERA as a generic term for tools and techniques used to gather available information about environmental risks and make judgments about them. The document outlines key steps in ERA, including hazard identification, exposure assessment, and risk estimation. It also discusses challenges like uncertainty, different levels of ERA, and the importance of risk communication. Overall, the document provides an introduction and overview of ERA, its relationship to environmental impact assessment, and considerations for effectively implementing ERA.
The document discusses compression stockings used to prevent deep vein thrombosis (DVT) during flights. It notes that in trials, stockings were below-knee compression of 10-30 mm Hg strength. It emphasizes proper fitting is important as stockings that are too tight can cut skin or prevent blood flow. It recommends wearing stockings before travel to ensure comfort and notes cost and availability can vary.
This document discusses economic evaluation in healthcare decision making. It defines economic evaluation as using scientific methods to compare costs and benefits of alternative interventions. The main types of economic evaluation are described as cost-effectiveness analysis, cost-utility analysis, cost-benefit analysis, and cost-minimization analysis. The document outlines the generic steps in economic evaluation including defining the question, identifying and valuing costs and benefits, analyzing costs and benefits, and determining decision rules based on incremental cost-effectiveness ratios. Limitations of economic evaluation for resource allocation are discussed, noting that many factors beyond cost-effectiveness play a role in funding decisions.
This document summarizes different adaptive designs that can be used in early phase oncology trials. It discusses modifications that can be made to dose levels, tumor types considered, and early termination of selected arms. Specific adaptive designs covered include model-based dose escalation methods like the N-CRM and mTPI, zone-based designs for combination treatments, methods for stopping early in single-arm trials, basket and umbrella trial designs, and an example of the Keytruda first-time-in-human study. The goal of adaptive designs is to incorporate interim data to modify trial aspects and make trials more efficient.
The document discusses evaluating the quality of science. It notes that current approaches are narrow and metric-driven. It argues that science quality should be judged based on its contribution to achieving desirable societal outcomes. Good science requires drawing other stakeholders into the process and recognizing that impact occurs through value chains involving cooperation. Innovation encompasses scientific and other activities, and evaluating science quality requires looking at both performance and behavior in achieving impact.
Waste Reduction and Waste-to-Energy Strategies for ProHealth CareGreg Fitzgerald
This document summarizes a research project analyzing waste reduction and waste-to-energy strategies for ProHealth Care, a large healthcare provider in Wisconsin. The research included interviews with industry professionals and analysis of primary and secondary sources on topics like waste definitions, regulations, and business case studies. Key conclusions determined that the healthcare industry generates significant waste and uses excessive energy. Recommendations included a multifaceted, stakeholder approach with both short-term waste reduction goals and long-term capital investments in renewable energy systems.
Cost utility analysis (CUA) is a form of economic analysis that measures the quality and quantity of life generated by healthcare interventions. It measures outcomes in quality-adjusted life years (QALYs) which account for both the length of life and the quality of life for time lived. CUA allows comparison of different healthcare interventions by measuring their costs and outcomes using a single metric (QALYs), taking into account costs and health outcomes. It is used when quality of life is an important outcome or when interventions impact both mortality and morbidity.

Health economics addresses questions primarily from the perspective of efficiency, maximising the benefits from available resources or ensuring benefits gained exceed benefits forgone. This presentation covers the concept, components, importance, factors influencing, steps and various types of evaluation in health economics.
This document discusses different types of economic analyses used to evaluate health interventions and policies, including cost-minimization analysis, cost-effectiveness analysis, cost-utility analysis, and cost-benefit analysis. It defines each type of analysis, how costs and outcomes are measured, and how alternatives are compared. Cost-effectiveness analysis is the most commonly used type for health care decisions. It compares interventions based on cost per unit of health outcome gained, such as cost per life-year or cost per case prevented. Conducting a cost-effectiveness analysis involves defining objectives, structuring alternatives, calculating costs and outcomes, and comparing cost-effectiveness ratios to determine the most efficient intervention.
Environmental valuation techniques a reviewDocumentStory
This document discusses various techniques for valuing environmental assets and services that are not traded in markets. It begins by defining environmental valuation and explaining concepts like total economic value and willingness to pay. It then describes several techniques in detail: hedonic pricing, travel cost method, contingent valuation method, production factor method, and averting behavior method. As an example, it summarizes a case study valuing the non-use benefits of maintaining a wetland in Greece using contingent valuation surveys.
This document discusses determining the high value information needed to improve decisions around development interventions. It focuses on four strategic objectives: decreasing food insecurity, managing environmental resources, reducing poverty among farmers, and increasing nutrition, health and wellbeing. The document outlines challenges like quantifying uncertainty, measuring outcomes, and showing the value of research. It also discusses using applied information economics to identify key metrics, quantify information value, and improve intervention design and impacts. The overall goal is to develop systems for measuring and analyzing impacts and tradeoffs to help stakeholders make better policies and intervention decisions.

Pharmacoeconomics involves identifying, measuring, and comparing the costs and consequences of different therapies to determine the most cost-effective option. There are several types of economic evaluations used in pharmacoeconomics, including cost-minimization analysis, cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis. Pharmacoeconomic analyses consider various factors like costs, perspectives, discounting, and sensitivity analysis and are used to inform coverage, treatment, and access decisions by health plans, manufacturers, and others. Pharmacists can assist in designing studies, evaluating literature, and applying results to clinical decision making and resource allocation.

Water is critical for meeting commitments of the Paris Agreement and achieving the Sustainable Development Goals. Our economies rely on water, with recent estimates putting the economic value of water and freshwater ecosystems at USD 58 trillion - equivalent to 60% of global GDP. At the same time, water related risks are increasing in frequency and scale in the context of climate change.
How are investments shaping our economies and societies exposure to water risk? What role can the financial system play in supporting water security? And how can increased understanding of how finance both impacts and depends on water resources spur action towards greater water security?
This OECD Green Talks LIVE on Tuesday 14 May 2024 from 15:00 to 16:00 CEST discussed the evolving landscape for assessing water risks to the financial system.
OECD Policy Analyst Lylah Davies presented key findings and recommendations from recent OECD work on assessing the financial materiality of water-related risks, including the recently published paper “Watered down? Investigating the financial materiality of water-related risks” and was joined by experts to discuss relevant initiatives underway.

In a tight labour market, job-seekers gain bargaining power and leverage it into greater job quality—at least, that’s the conventional wisdom.
Michael, LMIC Economist, presented findings that reveal a weakened relationship between labour market tightness and job quality indicators following the pandemic. Labour market tightness coincided with growth in real wages for only a portion of workers: those in low-wage jobs requiring little education. Several factors—including labour market composition, worker and employer behaviour, and labour market practices—have contributed to the absence of worker benefits. These will be investigated further in future work.
Measuring the Economic Value of Chemicals on Ecological System and Human Health, by Anna Alberini, University of Maryland
1. Measuring the Economic Value of
Chemicals on Ecological System and
Human Health
Anna Alberini
University of Maryland
OECD-ECHA Workshop, Helsinki, 6-8 July 2016
2. Regulating Chemicals
• Chemicals – contained in products, released into
the environment
• Should they be regulated?
• Cost-benefit analysis
– An input into decisionmaking about regulation
– Convert the various “positive” and “negative” effects of
proposed regulation into one metric: euro or dollars
– Regulation makes sense if benefits > costs
– Not easy
3. Costs
• Expenses incurred or
resources diverted from
other uses to comply with
the regulations
• Value of reduction in
output
• Limited to one or two
markets (partial
equilibrium analysis)…
• …or economy-wide
(general equilibrium
analysis)
Source: US EPA, Guidelines to Economic Analyses
(2012).
5. How do we estimate benefits?
• List likely physical or market effects (compared
to no-policy baseline), beneficiaries
• Attach a monetary value to each unit of these
effects
• Seek valuation method appropriate for each
such effect
• Methods
– Market methods
– Non-market methods
6. Types of Benefits
Environmental benefits
• Losses/gains to fisheries,
agriculture, manufacturing,
etc.
– To producers
– To consumers (higher prices,
lower output)
• Recreation
• Aesthetics (visibility, odors,
noise, etc.)
• Non-use values
• Avoided costs of supplying
alternate ecosystem
services
Human health
• Illnesses and fatalities due
to
– occupational exposure
(workers)
– environmental exposure
(general public)
– Consumption of products
containing the chemicals
(consumers)
Productivity effects
• Work days lost to illness
• Worker reduced
productivity even if at work
7. Non-market methods
• Travel cost method (TCM)
– Suitable for recreation sites
– Only use values
– Single-site visitation models v. discrete choice
models
• Hedonics
• Stated preference methods
9. TCM: Discrete choice models
• Based on random utility model
• Sites are described by attributes, including
environmental quality
• Explicitly allow for trading off attributes,
substitution between sites
• Can estimate the WTP for a change in one
attribute and/or the WTP for an entire
“modified site”
11. Hedonic pricing methods
• The price of a good is explained by the levels
of its attributes
• Housing prices (or rents) should depend on
structural characteristics of the home,
location, environmental quality at the site
• Regression equation:
iiii EP βx(ln)
12. Hedonic pricing methods (2)
• Use coefficient on environmental quality to see how
housing values increase if environmental quality is
improved
• Can be applied to other goods (e.g., cars, wages, etc.)
• Difficulties:
– Environmental quality likely to be correlated with other,
unobserved attributes of the neighborhood that influence
price
– If so, we may attribute to environmental quality effects that
are really due to something else
– Look for exogenous “shocks” (e.g., Davis, 2004) or repeat
sales
– Conventional housing price hedonics capture value of
environmental quality only if environmental quality doesn’t
change the decision to sell the home (Guignet, 2014)
13. Stated preference methods
• Based on surveys of members of the public
• Ask people what they would do, or how much
they would pay, under hypothetical but well
specified circumstances
• Suitable for a wide variety of goods, contexts,
changes in environmental quality (including
any not experienced before)
• Sometimes criticized because they are
hypothetical
14. Stated preference methods (2)
• Contingent valuation
– “Would you pay X euro for…?” yes/no
• Contingent behavior
– “Would you continue buying/going or stop
altogether if the price was X euro?”
• Discrete choice experiments
– “Which would you choose—A, B, or neither?”
16. Valuing effects of chemicals
on human health
• Types of effects
– Morbidity
– Mortality
• Description of effects
– Duration or frequency (acute v. chronic)
– Severity (bed disability day, work loss day,
restricted activity day)
– Affected parties (children, elderly, sensitive
individuals)
17. A Simple Model for Morbidity
• Individual or household utility depends on
consumption, leisure time, and sick days: U(X,L,D)
• Dose-response function: D=D(P,A)
• Choose consumption and leisure time to maximize
utility, subject to budget constraint
• Budget constraint states that…
– we spend what we earn
– sick days reduce work time (and hence income) and create
medical expenditures
– plus we spend money on averting activities (self-
protection)

19. Assumptions
• Pollution enters in the utility function only via
its effect on sick days
• Work time is flexible
• The specific nature of the chemical is not
important. All that matters is the effect of
pollution or chemicals on sick days.
20. Is this model suited for chemicals?
• Yes and no
• Yes: if the chemicals cause minor symptoms
without lasting consequences (e.g., itchy eyes,
headaches, …)
• No: if the chemicals cause serious chronic
illnesses (e.g., diabetes), neurological and
developmental problems in babies and
infants, irreversible reproductive system
effects
21. Chemicals with neurological and
developmental effects
• Lead, mercury, heavy
metals
• Effects on babies, infants,
children
• Exposures to high levels
physical and
neurological effects
cognitive difficulties,
reduced school
attendance lower
educational attendance
lower wages
• Damage from chemical =
(Lifetime wage differential
+ additional costs)
attributable cases
• Landrigan et al. (2002),
Grosse et al. (2002),
Drake (2016), Trasande
(2016)
• Misses the disutility and
suffering of individual and
parents
• A lower bound to true
damage
22. Landrigan’s figures
• Average lead level in blood in 5-year-olds: 2.7
g/dL, which is predicted to reduce IQ by 0.675
points
• 1 IQ point lost 2.39% loss in lifetime earnings
• So 0.675 IQ points lost = 1.61% loss in lifetime
earnings
• …or USD 21,014 for boys and USD 12,394 for girls
• Nationwide USD 27.8 billion (boys) and USD 15.6
billion (girls) (1997 USD)
23. Loss of productivity
• In air pollution context, loss of productivity is
because of work loss days
• …and in the air pollution context,
– Zivin et al. (2011) with agricultural workers
– Chang et al. (2014) with workers at a pear-packing
plant
find lower productivity at work on high pollution
days
• Can chemicals have similar effects?
24. Mortality effects
• Exposure to chemicals via the environment or use
of products linked to increase mortality risks
(cancer, effects on cardiovascular system,
kidneys, liver, etc.)
• Diabetes and shorter life expectancy
• Benefits of regulation:
– Expected lives saved Value of a Statistical Life (VSL)
or
– Expected life-years saved Value of a Statistical Life
year (VOLY)
25. What is the Value of a Statistical Life?
(a.k.a. Value of a Prevented Fatality)
• A summary measure of how much someone is
prepared to pay to reduce his risk of dying by a small
amount
• Grounded in economic theory
• If I am willing to pay 500 euro to reduce risk by
1/10,000 (=0.0001), the VSL is 500 10,000 =
5,000,000 euro
• Values used by agencies in policy analyses:
– US EPA USD 7.4 million (2006 dollars)
– DG-Environment central value EUR 1.5 million
– OECD recommends a base value USD 3.6 million for EU-27
26. How is the VSL estimated?
Compensating wage studies
• VSL inferred from the
coefficient on fatal risks
• Econometric difficulties,
measurement of risks,
assumption that workers
actually know their risks,
heterogeneity and self-
protection
Hedonic regressions for
other goods
• Car prices depend on car
characteristics, including
safety
• Home prices change
when environmental risks
are discovered
Consumer expenditures on
safety equipment
Stated preference studies
iiiiiii WCqqpw 43210 )(βx
27. Can we apply existing estimates of
the VSL to the effects of chemicals?
• Only if we presume that VSL figures from
workplace or transportation accident context
can be applied to chemicals
• Must adjust for latency—risk reductions from
regulating certain chemicals now likely to
occur in the future
• Is the cancer VSL higher?
28. Cancer risks
• Risk assessments estimate excess lifetime
cancer risks, i.e., number of cases of cancer
• Useful to separate the Value of a Statistical
Case of Cancer (VSCC) (just getting cancer,
being ill and receiving treatment) from the
cancer VSL (dying from it)
• Avoid double counting

37. Chemicals as emerging pollutants
• How should valuation be done when the
effects of chemicals are unknown or only
tentative?
38. Points for discussion
1. Responses in related markets have been
observed even when causation had not been
established (Davis, 2004) or chemicals are not
identified (e.g., fracking)
2. The public has consistently demonstrated to be
willing to switch to and pay more for safer
products
– Survey of the Canadian public by Industrial
Economics (2015)
– CAD 49 a month to switch to non-carcinogenic
products, and CAD 17 – 35 a month to avoid adverse
effects on soil, air or water.
39. Discussion 2
4. When the effects of a chemical are uncertain,
we say that they are “ambiguous.”
6. Ambiguity may arise when people are told
conflicting information on such effects.
40. Discussion 3
7. Fox and Tversky (1995) warn that ambiguity
aversion may arise when people are comparing
ambiguous and clear risky prospects, but
diminishes or disappear when risky prospects are
evaluated in isolation.
8. Ambiguity aversion would lead to attaching a
lower value to an ambiguous risky prospect than to
a comparable but clear risk prospect.
9. But do these claims carry over to when the
human or environmental effects are ambiguous?
41. Discussion 4
10. Theoretical work by Treich (2010) and Courbage and
Rey (2015) about the VSL and ambiguity aversion
– Effect of ambiguity aversion on VSL cannot be signed
(Courbage and Rey)
– Ambiguity premium likely to be small (Treich)
11. Empirical work: WTP to reduce or eliminate health
risks not affected by ambiguity, whether or not in
isolation (Goldberg et al., 2009; baby formula
contaminated with pathogens).
12. Nature of the chemical unlikely to influence WTP
much.
42. In conclusion…
• Various methods for estimating the benefits of
reducing exposure to chemicals via the
environment or consumer products
• All methods have s
• Many benefits are…
– underinvestigated (productivity, reproductive health
or birth defects)
– require major updates (e.g., Landrigan figures with
lead and IQ; chronic bronchitis, see Alistair Hunt)
– miss out important components of WTP (suffering
and disutility)
43. Conclusions (2)
• But my reading of the evidence is that ambiguity
and the specific chemical or its source are
unlikely to make a big difference on the WTP for
the symptoms/effects
• Difficulties with..
– valuing probabilistic outcomes
– Valuing multiple/simultaneous/cumulative chemical
exposures
• Recommend research on the above, but also
going ahead with applying WTP figures to
chemicals regulations

(2014) for ECHA
– Ex ante
– Stated preference
study to value an
increase in the
probability of
conception
– Vitamins (private good)
or chemical-free
product (public good)
– Value of a Statistical Pregnancy
(VSP):
• 40,000 euro (private good)
• 33,000 euro (public good)
• 40,000 euro (public good but
respondents who intend to have a
child)
– Controlling for possible co-
benefits, the VSP is
• 25,000 euro
• 11,000 euro
• 20,000 euro
– The same survey also elicits WTP
to reduce the risk of low birth
weight and birth defects

47. The Benefits of Avoiding Cancer (or
Dying from Cancer):
Evidence from a Four-country Study
Anna Alberini and Milan Scasny
48. Research Questions
• What VSCC and cancer VSL figures should be
used in EU/ECHA policy analyses?
• How important are quality of life and pain in
explaining the willingness to pay to reduce
cancer mortality risks?
• In stated preference studies
– Can respondents handle several quantitative
attributes (here, two probabilities and one cost)?
– How do qualitative attributes fare?
49. Approach
• Stated Preferences
• In each choice card, the respondent must
choose between an alternative that reduces
risks (at a cost) and the status quo =
• = dichotomous-choice (DC) contingent
valuation (CV) questions
• Total of 7 DC CV questions per respondent
50. What Good Are We Valuing?
• Reduction in the risk of dying from cancer
• This risk is the product of
– Risk of getting cancer
– Risk of dying from cancer, conditional on getting
cancer in the first place
• Generic cancer (no mention of organs
affected, type, etc.)
• Description of quality of life impacts and pain
51. Attributes and Levels
Reduction in the chance of getting
cancer within the next 5 years
0 (baseline), 2, 3, 5 in 1000 over
5 years
Chance of survival at 5 years (if you get
cancer)
60% (baseline), 65%, 70% and
80%
Effects on everyday activities (if you get
cancer)
Fully active
No heavy physical work
Unable to work
Confined to bed half of the time
Pain (if you get cancer) during
treatment, recovery, or any other times
Mild pain
Moderate pain

52. Estimation details
• We don’t observe the actual WTP
• We only have yes/no responses to each choice
card
• Probit model – RHS is augmented with COST
• Random effects probit to allow for correlated
responses
• In earlier slides, QoL and Pain are additive—in
alternate specifications, they can be entered as
interactions with the reduction in the risk of
dying
• Country fixed effects always included
53. Example Benefit-Cost Analysis:
Rule for Mercury from Power Plants, US EPA
Category of benefits or costs Annual benefits of the final rule in 2016
(3% discount rate)(2007 USD)
Total monetized benefits USD 37 to USD 90 billion
Partial Hg-related benefits
(consumption of fish and its effects
through maternal exposure)
USD 0.004 to USD 0.006 billion
PM2.5-related co-benefits (mortality,
non-fatal illnesses, hospitalizations,
restricted activity days)
USD 36 to USD 89 billion
Climate related co-benefits USD 0.36 billion
Total social costs USD 9.6 billion
Net benefits USD 27 to USD 100 billion
Non-monetized benefits Include visibility in class I areas; other
neurological and health effects of Hg
exposure; health effects of ozone;
ecosystem effects; health effects from
commercial and non-freshwater fish
