How lost earnings analysis applies to Product Liability in Wisconsin

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.

Wisconsin courts and expert standards

Wisconsin courts screen expert testimony for reliability: the judge asks whether the economist is qualified, whether the opinion rests on sufficient facts and reliable principles and methods, and whether those methods were reliably applied to the case. An economic damages report is written to that inquiry, with each rate and table traced to a published source.

Where these cases are heard

Highest court: Wisconsin Supreme Court. Court system: wicourts.gov.

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

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Wisconsin Department of Workforce Development, Worker's Compensation Division.

Damages framework

Wisconsin pairs a wrongful death action for the beneficiaries' pecuniary injury and a limited allowance for loss of society and companionship with a survival action for the decedent's own claims. Recovery is barred once the plaintiff's fault exceeds the defendant's, the common-law collateral source rule applies outside medical malpractice where evidence of collateral payments is admissible, statutory limits apply to noneconomic damages in medical malpractice claims, and interest on a verdict that beats a rejected statutory offer of settlement runs from the date of the offer.

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 Wisconsin product liability matters

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

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.

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

Wisconsin courts screen expert testimony for reliability: the judge asks whether the economist is qualified, whether the opinion rests on sufficient facts and reliable principles and methods, and whether those methods were reliably applied to the case. An economic damages report is written to that inquiry, with each rate and table traced to a published source. Product Liability cases venued in Wisconsin are heard in the Circuit Court (General jurisdiction; one in each of 72 counties; all civil, criminal, family, and probate matters), with final appeals to the Wisconsin Supreme Court. Matters within federal jurisdiction proceed in the Eastern District of Wisconsin and Western District of Wisconsin.

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

Wisconsin pairs a wrongful death action for the beneficiaries' pecuniary injury and a limited allowance for loss of society and companionship with a survival action for the decedent's own claims. Recovery is barred once the plaintiff's fault exceeds the defendant's, the common-law collateral source rule applies outside medical malpractice where evidence of collateral payments is admissible, statutory limits apply to noneconomic damages in medical malpractice claims, and interest on a verdict that beats a rejected statutory offer of settlement runs from the date of the offer. 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 Wisconsin rules to a documented figure.
