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

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.

Arizona courts and expert standards

Arizona courts screen expert opinion for reliability before it reaches the jury: the judge asks whether the witness is qualified, whether the method rests on sufficient facts and reliable principles, and whether those principles were applied reliably to the case. An economic damages report is written to that inquiry, with each input tied to the record and each data series identified by source.

Where these cases are heard

Highest court: Arizona Supreme Court. Court system: azcourts.gov.

Federal venues: District of Arizona.

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Industrial Commission of Arizona.

Damages framework

Arizona's wrongful death action belongs to the surviving spouse, children, parents, or estate and is measured by their own losses, while the decedent's pre-death claims survive to the estate without damages for the decedent's pain and suffering. The state constitution bars legislative limits on the amount recovered for death or injury, pure comparative fault reduces the award in proportion, evidence of collateral-source payments is admissible in medical malpractice cases but not in ordinary injury claims, and prejudgment interest is generally limited to liquidated sums.

Typical deliverables

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 Arizona product liability matters

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

The same four steps apply to a product liability case venued in Arizona; 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 Arizona courts ask of lost earnings analysis before it reaches the fact finder?

Arizona courts screen expert opinion for reliability before it reaches the jury: the judge asks whether the witness is qualified, whether the method rests on sufficient facts and reliable principles, and whether those principles were applied reliably to the case. An economic damages report is written to that inquiry, with each input tied to the record and each data series identified by source. Product Liability cases venued in Arizona are heard in the Superior Court (General jurisdiction; larger civil cases, felonies, family law, probate), with final appeals to the Arizona Supreme Court. Matters within federal jurisdiction proceed in the District of Arizona.

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

Arizona's wrongful death action belongs to the surviving spouse, children, parents, or estate and is measured by their own losses, while the decedent's pre-death claims survive to the estate without damages for the decedent's pain and suffering. The state constitution bars legislative limits on the amount recovered for death or injury, pure comparative fault reduces the award in proportion, evidence of collateral-source payments is admissible in medical malpractice cases but not in ordinary injury claims, 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 Arizona rules to a documented figure.
