How Lost Earnings and Earning Capacity Analysis applies to Traumatic Brain Injury in Washington

Brain injury claims often present a large lost earnings figure because cognitive and behavioral effects can end a career even when physical function returns, and a young claimant's worklife is long. The economist builds the but-for path from the earnings history or, for a young person, from occupational data for the path they were on, and compares it with a post-injury path that may be no competitive work, work only with supports, or work at a lower level. The neuropsychological and work-capacity opinions in the record define that path; the report shows the loss under each opinion when they differ and states how the total moves with residual capacity.

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

Two components usually dominate: future lost earnings across a long worklife for a young person, and the present value of attendant care and supervision when the plan calls for daily hours of paid help. Because the level of supervision and the person's residual work capacity are both matters of expert opinion, the report's total is highly sensitive to those inputs, and the life expectancy used for the care stream is a second source of dispute. Mild injury with persistent symptoms presents a narrower claim built on reduced hours, lost advancement, and periodic treatment.

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 traumatic brain injury matters

How is lost earnings analysis built for a traumatic brain injury case in Washington?

The same four steps apply to a traumatic brain injury case venued in Washington; the damages framework above decides which components enter the total. Establish the but-for earnings path from the person's history or, for a young person, from occupational data for the path they were on. Draw the post-injury path from actual earnings and the work-capacity opinions in the record, and measure the earnings gap over the remaining worklife. Value household services and family supervision from time-use data and local rates, and price the care plan item by item with medical cost growth. Discount every future stream to present value at a stated rate and show the total under each supervision and work-capacity scenario.

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. Traumatic Brain Injury 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 traumatic brain injury 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.
