KW Economics prepares household services analysis for product liability cases venued in Arizona: what the loss claim consists of, the records that drive it, and a present value built to Arizona damages rules and venues. Plaintiff and defense.
Product liability claims often involve children, homemakers, and retirees whose economic loss is concentrated in household work rather than wages, so the household services valuation is frequently the largest component. The economist draws the pre-injury hours from the household's account and time-use data for a person of the same circumstances, apportions the loss by category using the medical restrictions in the record, prices each category at the local replacement wage, and projects the loss over the period of limitation or the person's expected life. In a mass tort setting the same documented method is applied to each claimant's own household so results are consistent in method and individual in result.
Replacement-cost valuation of the household production an injured or deceased person can no longer provide: meal preparation, cleaning, home and vehicle maintenance, shopping, child care, and care of other household members. The hours are drawn from national time-use data adjusted to the person's household composition and pre-injury role, and each category is priced at the local wage for the occupation that would replace it, then projected and discounted over the period of loss.
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 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.

Federal venues: District of Arizona.
Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Industrial Commission of Arizona.
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.
We issue the final report and provide deposition and trial testimony and rebuttal of opposing household services opinions.
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.

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.
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.
