10.2 Monetizing Costs and Benefits
4 min read•august 7, 2024
is all about putting a price tag on everything, even stuff that doesn't have a clear market value. This section dives into how we can assign dollar values to things like clean air, public parks, and even human life.
It's not just about counting cash – it's about figuring out what people are willing to pay for things they care about. We'll look at clever ways economists estimate these values, from observing market behavior to asking people directly in surveys.

- Market prices directly observe prices of goods and services traded in markets
- Shadow prices estimate the value of non-market goods by using prices of related market goods as a proxy (water, air quality)
- method estimates the value of a non-market good by observing how the price of a market good changes when the non-market good changes
- Based on the idea that the price of a market good is a function of its characteristics
- Example: the value of air quality can be estimated by looking at how housing prices change with air pollution levels
- Travel cost method estimates the value of a recreational site by observing how much people spend to travel to the site
- Assumes that the value of a site is at least as much as what people are willing to pay to get there
- Example: estimating the value of a national park by surveying visitors about their travel costs
Non-Market Valuation Techniques
- Contingent valuation directly asks people to state their for a non-market good or service
- Involves creating a hypothetical market through a survey
- Example: asking people how much they would be willing to pay for cleaner air
- Revealed preference methods infer the value of non-market goods from observed behavior in related markets
- Includes hedonic pricing and travel cost methods
- Based on the idea that people "reveal" their preferences through their market choices
- Stated preference methods ask people to make choices in hypothetical situations to infer their preferences
- Includes contingent valuation and choice experiments
- Can be used to value goods that do not yet exist or for which no related market goods exist
Valuation Techniques
Preference Elicitation Methods
- Contingent valuation directly asks individuals to state their willingness to pay (WTP) or willingness to accept (WTA) for a change in a non-market good or service
- WTP is the maximum amount an individual would pay to obtain a good or avoid something undesirable
- WTA is the minimum amount an individual would accept as compensation to give up a good or tolerate something undesirable
- Typically done through surveys that create a hypothetical market scenario
- Revealed preference methods infer the value of non-market goods from actual behavior in related markets
- Rely on the assumption that individuals' market choices reflect their underlying preferences
- Examples include hedonic pricing (housing market choices) and travel cost methods (recreational choices)
- Stated preference methods ask individuals to make choices in hypothetical scenarios, rather than observing their actual choices
- Allows estimation of values for goods that do not yet exist or have no related market goods
- Choice experiments present a series of choice sets and ask respondents to choose their preferred option in each set
Limitations and Challenges
- Hypothetical bias in stated preference methods since respondents are not actually paying
- Difficulty in creating realistic, understandable scenarios
- Protest responses from respondents who object to the valuation exercise
- Anchoring bias from starting point values in bidding games
- Aggregation of individual values to society-wide measures
- Accounting for differences between WTP and WTA measures
Measuring Health Outcomes
Mortality-Based Measures
- (VSL) measures the willingness to pay for small reductions in mortality risk
- Derived from observed wage differentials for risky jobs or stated preference surveys
- Assumes a linear relationship between risk and willingness to pay
- Example: if people are willing to pay 1000 / (1/10,000) = $10 million
- (VSLY) measures the willingness to pay for a one-year reduction in life expectancy
- Derived by dividing the VSL by the average remaining life expectancy
- Example: if the VSL is 10 million / 40 = $250,000
Morbidity-Based Measures
- (QALYs) measure the value of health states by weighting years of life by the quality of those years
- Quality weights range from 0 (death) to 1 (perfect health)
- Weights can be derived using standard gamble, time trade-off, or visual analog scale methods
- Example: 2 years in a health state with a quality weight of 0.5 is equivalent to 1 QALY (2 * 0.5 = 1)
- (DALYs) measure the burden of disease by summing years of life lost due to premature death and years lived with disability
- Disability weights range from 0 (perfect health) to 1 (death)
- Example: if a disease causes 100 premature deaths (10 years of life lost each) and 200 people to live with a disability weight of 0.2 for 20 years, the total DALYs lost is (100 * 10) + (200 * 20 * 0.2) = 1,800
Challenges in Health Outcome Measurement
- Valuing health risks involves considerable uncertainty and variability across individuals
- Health state valuations may not capture all relevant aspects of health-related quality of life
- Disability weights in DALYs do not account for the context or duration of the disability
- Aggregating QALYs or DALYs across individuals raises concerns
- Discounting future health outcomes is controversial and can substantially impact results
Key Terms to Review (23)
Cost-benefit analysis: Cost-benefit analysis is a systematic approach used to evaluate the economic pros and cons of different policy options by comparing the total expected costs against the total expected benefits. This method helps policymakers decide whether a proposed action is worthwhile, guiding the allocation of resources in a way that maximizes societal benefits.
Cost-benefit ratio: The cost-benefit ratio is a quantitative measure used to compare the costs and benefits of a particular decision or project, providing insight into its overall value. By expressing the relationship between the monetary costs incurred and the benefits gained, this ratio helps decision-makers evaluate the feasibility and effectiveness of policy options or investments. A cost-benefit ratio greater than one indicates that benefits outweigh costs, making it a favorable option.
Cost-effectiveness analysis: Cost-effectiveness analysis is a systematic approach used to compare the relative costs and outcomes (effects) of different courses of action. It helps decision-makers evaluate the efficiency of various policies by assessing how much is spent to achieve specific health outcomes, making it particularly valuable in resource allocation decisions within healthcare and other sectors.
Disability-adjusted life years: Disability-adjusted life years (DALYs) are a measure used to assess the overall burden of disease and injury by quantifying the number of years lost due to ill health, disability, or early death. This metric combines both the years of life lost due to premature mortality and the years lived with disability, providing a comprehensive view of population health. By using DALYs, policymakers can better understand the impact of various health interventions, prioritize resources, and monetize costs and benefits more effectively.
Discount rate: The discount rate is a key financial concept that reflects the time value of money, indicating how much future cash flows are worth in today's terms. It plays a critical role in evaluating the present value of costs and benefits over time, guiding decisions in cost-benefit analysis and investment appraisals. Understanding the discount rate is essential for effectively monetizing costs and benefits, as it helps to assess the attractiveness of various options by comparing their net present values.
Efficiency: Efficiency refers to the optimal use of resources to achieve desired outcomes with minimal waste or cost. In public policy analysis, it signifies the balance between inputs and outputs, ensuring that the maximum benefit is derived from the least amount of resources, thereby making programs and policies more effective and sustainable.
Environmental Cost Assessment: Environmental cost assessment is the process of identifying, quantifying, and evaluating the costs associated with environmental impacts resulting from a project or policy. This assessment not only includes direct financial costs but also considers indirect costs such as social and ecological effects, helping to provide a more comprehensive understanding of the trade-offs involved in decision-making. By monetizing these costs, stakeholders can better gauge the overall benefits and drawbacks of various options.
Equity: Equity refers to the principle of fairness and justice in the distribution of resources and opportunities among individuals or groups. It emphasizes the need to consider differing circumstances and needs to ensure that all individuals can achieve similar outcomes, particularly in policy-making. This concept connects to various aspects such as the choice of instruments, design principles, and the economic analysis of costs and benefits, highlighting the importance of addressing inequalities to achieve effective and just policies.
Excel modeling: Excel modeling refers to the process of using Microsoft Excel to create a mathematical representation of a real-world scenario, allowing users to analyze data, forecast outcomes, and make informed decisions. This involves building spreadsheets that can simulate various scenarios, calculate costs and benefits, and evaluate the impact of different variables on outcomes, which is crucial in assessing projects and policies.
Externalities: Externalities are costs or benefits that affect third parties who did not choose to incur those costs or benefits. They occur when the actions of individuals or businesses have unintended consequences on others, either positively or negatively, and these impacts are not reflected in market prices. Understanding externalities is crucial for evaluating the true social costs and benefits associated with economic activities, especially when monetizing those impacts in public policy analysis.
Hedonic Pricing: Hedonic pricing is a method used to estimate the economic value of an item by breaking it down into its component attributes and determining how much each contributes to the overall price. This approach is especially useful for valuing non-market goods like environmental benefits, as it helps quantify how specific factors impact people's willingness to pay. Understanding hedonic pricing allows for a more comprehensive analysis of costs and benefits, particularly when considering policies that affect public resources.
Net Present Value: Net Present Value (NPV) is a financial metric that calculates the difference between the present value of cash inflows and the present value of cash outflows over a specific time period. It helps in assessing the profitability of an investment by discounting future cash flows back to their present value, enabling decision-makers to understand whether the investment will yield a profit or a loss. By incorporating the concept of time value of money, NPV allows for a comprehensive evaluation of costs and benefits associated with any project or investment.
Opportunity Cost: Opportunity cost is the value of the next best alternative that is forgone when making a decision. This concept is crucial in evaluating choices because it emphasizes that every choice has a trade-off, meaning that when resources are allocated to one option, those resources cannot be used for another. Understanding opportunity cost helps in comparing the relative benefits of different options, guiding individuals and policymakers in making informed decisions.
Policy simulation tools: Policy simulation tools are analytical instruments used to model and predict the outcomes of various policy decisions by simulating their impacts in a controlled environment. These tools allow policymakers to explore different scenarios, assess potential benefits and costs, and ultimately make more informed decisions about public policies. By providing a visual representation of data and potential outcomes, these tools facilitate a deeper understanding of complex issues and help ensure that resources are allocated effectively.
Quality-adjusted life years: Quality-adjusted life years (QALYs) are a measure used to assess the value of medical interventions by combining both the quantity and quality of life gained from those interventions. A QALY reflects a year of life in perfect health, with adjustments made for the quality of life experienced, allowing policymakers to evaluate healthcare programs and compare their effectiveness. This metric is vital in determining how resources can be allocated efficiently within healthcare systems.
Regulatory Impact Assessment: Regulatory Impact Assessment (RIA) is a systematic process used to evaluate the potential effects of proposed regulations, ensuring that decision-makers understand the economic, social, and environmental implications. By analyzing both the costs and benefits of regulations, RIA helps in crafting effective policies that maximize positive outcomes while minimizing negative impacts.
Risk Assessment: Risk assessment is the process of identifying, analyzing, and evaluating potential risks that may negatively impact a project or policy. This process helps policymakers understand uncertainties and make informed decisions by weighing the likelihood and consequences of adverse outcomes. It connects closely to policy design, cost-benefit analysis, and understanding value conflicts when making trade-offs.
Sensitivity analysis: Sensitivity analysis is a technique used to determine how different values of an independent variable affect a particular dependent variable under a given set of assumptions. This method helps in understanding the impact of uncertainty in input variables on outcomes, making it crucial for decision-making and evaluating risks and trade-offs.
Social Return on Investment: Social Return on Investment (SROI) is a framework for measuring and accounting for the social, environmental, and economic value generated by an organization or program, often expressed as a ratio of net social value to the invested capital. SROI provides insights into the broader impact of investments beyond financial returns, emphasizing the importance of capturing intangible benefits and costs associated with social initiatives.
Tangible benefits: Tangible benefits refer to measurable and quantifiable advantages that can be directly attributed to a specific action, policy, or investment. These benefits often include financial savings, increased productivity, or improved quality of life, which can be easily calculated and expressed in monetary terms. Understanding tangible benefits is crucial for evaluating the overall effectiveness and efficiency of public policies.
Value of statistical life: The value of statistical life (VSL) is a monetary figure used to quantify the benefit of reducing the risk of death in policy analysis and economic evaluations. It represents the amount of money that individuals are willing to pay for small reductions in their risks of dying, essentially providing a way to assess the economic impact of regulations and safety measures. This concept plays a crucial role in monetizing costs and benefits associated with health, safety, and environmental policies.
Value of statistical life year: The value of statistical life year (VSLY) is a metric used to quantify the economic value of a human life based on the concept of life years gained or lost. It connects health outcomes to economic analysis, allowing policymakers to weigh the costs and benefits of interventions by assigning a monetary value to health improvements or mortality reductions.
Willingness to pay: Willingness to pay is the maximum amount an individual or group is ready to spend for a good or service, reflecting the perceived value and utility they associate with it. This concept plays a crucial role in evaluating how much people value specific benefits and how that translates into monetary terms, especially when considering the advantages and costs in policy decisions.
