Hedonic Damages

When it is used

Hedonic damages analyses are offered in jurisdictions that permit them. Many jurisdictions permit generalized loss-of-enjoyment-of-life testimony but exclude dollar quantification.

Step-by-step

1. Identify jurisdiction-specific admissibility rules
2. When permitted, apply value-of-statistical-life (VSL) literature (Viscusi & Aldy, 2003) with appropriate adjustments
3. Document the methodology, base data, and case-specific adjustments

Data sources

• VSL literature (EPA, DOT Federal guidance on VSL)
• Peer-reviewed labor market and contingent valuation studies

How the analysis is performed

Where a forum allows a hedonic figure, the analysis proceeds in four steps that stay visible in the report. First, the economist establishes the value of a statistical life from the published willingness-to-pay literature: the estimates come from studies of the wage premium workers accept for differences in fatal risk between jobs and from studies of what people pay to reduce small mortality risks, and the report states which estimates it relies on and why. Second, that lifetime value is converted to an annual value of the enjoyment of life by spreading it over the remaining life expectancy at the discount rate the report uses elsewhere. Third, the loss is applied as a proportion: the economist does not decide how much of life's enjoyment the injury removed, but takes a rating of that loss from a physician, psychologist or other qualified evaluator in the record and multiplies the annual value by it. Fourth, the annual loss is projected over the person's life expectancy and reduced to present value, in the same manner as any other future loss.

Where the forum admits only qualitative testimony, the economist's role is to explain the concept and its distinction from earnings loss and from pain and suffering, without stating a figure. Attorneys confirm the governing rule for their case.

The data sources and what each contributes

Three kinds of source enter the calculation. The value-of-statistical-life estimates come from the peer-reviewed reviews of labor market and contingent valuation studies (Viscusi & Aldy, 2003) and from the guidance federal agencies publish for regulatory benefit analysis (U.S. Environmental Protection Agency, n.d.), which the report cites as the source of the range it uses rather than as a finding about the claimant. The horizon comes from the national life tables for the person's age and sex (Arias et al., 2025), adjusted only where a physician has given a condition-specific opinion. The discount rate comes from the same Treasury-based or other series the report uses for earnings (U.S. Department of the Treasury, n.d.). The loss proportion is the one input the economist cannot supply and must cite to a named evaluator.

How the result enters the report

A hedonic figure is presented in its own section of the damages report, apart from lost earnings, lost household services and future care costs, and it is totaled separately. Two reasons drive the separation. The first is admissibility: because courts in many jurisdictions exclude the quantified figure while admitting the rest of the economist's work, a self-contained section can be struck without disturbing the other opinions. The second is transparency: the section shows the value-of-statistical-life range, the annual conversion, the loss proportion and its source, the horizon and the discount rate on one page, so an opposing expert can substitute any input and reproduce the result. Where the forum's posture is unsettled, the report may present the figure as an illustration beside a qualitative description, and the economist testifies to whichever part the court admits.

Limitations

Hedonic damages are often excluded at the quantification stage. Even where permitted, the methodology is subject to substantial admissibility scrutiny.

Admissibility

Admissibility is jurisdiction-dependent and often limited. Courts frequently exclude dollar quantification (Mercado v. Ahmed, 974 F.2d 863 (7th Cir. 1992)) while permitting qualitative testimony on loss of enjoyment of life.
