How Lost Earnings and Earning Capacity Analysis applies to Product Liability in Washington

Product liability claims often involve an injured person whose exposure to the product bears no relation to their occupation, so the lost earnings analysis is built from that person's own path rather than from the circumstances of the injury. The economist establishes the but-for earnings base from the earnings history or, for a child, student, or homemaker, from the educational path and occupational earnings data, projects it over the applicable worklife with growth, and sets against it the post-injury path the work-capacity opinions support. In a mass tort setting the same documented method is applied to each claimant's own records so results are consistent in method and individual in result.

Past and future lost earnings and fringe benefits for a person whose injury has removed them from work or reduced what they can earn. The analysis builds from the earnings history, projects the but-for path over the person's expected worklife with wage growth, and discounts the future stream to present value. When the person can still work in a reduced capacity, the loss is framed as diminished earning capacity, with the post-injury path drawn from a vocational opinion or the treating record and offset against the but-for projection.

Where the damages concentrate

The exposure tracks the injury: burns, amputations, and neurological injuries produce large future earnings and care losses; less severe injuries produce a bounded past loss and limited future treatment. Because product cases often involve children, homemakers, and retirees, the household services and care components frequently outweigh the earnings loss, and the analysis must be built from those components rather than from wage records that do not exist. For fatal injuries the exposure follows the wrongful death structure with the personal consumption deduction as the key assumption.

Washington courts and expert standards

Washington courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community and whether the economist is qualified by training and experience to apply it, leaving disputes over the inputs to cross-examination. The methods of forensic economics are published and long used, so the examination of a damages report usually turns on its assumptions and their support in the record.

Where these cases are heard

Highest court: Washington Supreme Court. Court system: courts.wa.gov.

Federal venues: Western District of Washington, Eastern District of Washington.

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Washington Department of Labor and Industries.

Damages framework

Washington pairs a wrongful death action for the beneficiaries' pecuniary loss, which was broadened in recent years to reach more family members, with a general survival action in which the estate recovers the decedent's economic losses, including net future earnings, and a limited survival claim for the decedent's own pre-death suffering. Pure comparative fault reduces the award in proportion, the collateral source rule applies outside medical malpractice where evidence of collateral payments is admissible, statutory limits on noneconomic damages have been held unconstitutional, and prejudgment interest is generally limited to liquidated sums.

We issue the final report in disclosure-ready form and provide deposition and trial testimony, rebuttal of opposing economic opinions, and updated calculations as new records arrive.

Frequently asked: Lost earnings analysis in Washington product liability matters

How is lost earnings analysis built for a product liability case in Washington?

The same four steps apply to a product liability case venued in Washington; the damages framework above decides which components enter the total. Establish the but-for path from the earnings history or, for a child, student, or homemaker, from the educational path, occupational data, or the household work performed. Draw the post-injury path from actual earnings and the work-capacity opinions, and project both paths over the applicable worklife or life expectancy with growth. Value household services from time-use data and local rates, and price future care from the life care plan with category-specific cost growth. Discount every stream to present value at a stated rate and, where there are multiple claimants, apply one documented methodology to each record.

What do Washington courts ask of lost earnings analysis before it reaches the fact finder?

Washington courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community and whether the economist is qualified by training and experience to apply it, leaving disputes over the inputs to cross-examination. The methods of forensic economics are published and long used, so the examination of a damages report usually turns on its assumptions and their support in the record. Product Liability cases venued in Washington are heard in the Superior Court (General jurisdiction; one in each of 39 counties; all civil, criminal, and domestic matters), with final appeals to the Washington Supreme Court. Matters within federal jurisdiction proceed in the Western District of Washington and Eastern District of Washington.

How does the Washington damages framework shape lost earnings analysis in a product liability case?

Washington pairs a wrongful death action for the beneficiaries' pecuniary loss, which was broadened in recent years to reach more family members, with a general survival action in which the estate recovers the decedent's economic losses, including net future earnings, and a limited survival claim for the decedent's own pre-death suffering. Pure comparative fault reduces the award in proportion, the collateral source rule applies outside medical malpractice where evidence of collateral payments is admissible, statutory limits on noneconomic damages have been held unconstitutional, and prejudgment interest is generally limited to liquidated sums. The report presents past and future amounts separately, states every rate and table with its source, and shows the result under the alternatives the other side is likely to argue, so counsel can apply the Washington rules to a documented figure.
