How Personal Injury Economic Damages applies to Product Liability in Illinois

Product liability injuries such as burns, amputations, and neurological injuries produce large future earnings and care losses, while the injured person is often a consumer, child, homemaker, or retiree whose earnings history does not fit the injury. The integrated report is built from the components the record supports: earnings projected from the person's own path or educational trajectory, household services from the household's account and time-use data, and future care from the life care plan with category-specific cost growth, all carried to one present value on consistent assumptions. In a mass tort setting the economist applies one documented method across the claimants so each figure traces to its own record.

An integrated economic damages report for an injured person: lost earnings and fringe benefits, lost household services, and the present value of future medical and care costs supplied by treating providers or a life care plan. One report carries every economic component to a single present value with consistent growth, discount, and life expectancy assumptions, so counsel can present the damages as a whole and the jury sees one set of numbers.

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.

Illinois courts and expert standards

Illinois courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community, and separately whether the economist is qualified by training and experience and applied the method to the facts of the case. Forensic economic methods for lost earnings, worklife, and present value are published and long used, so the examination usually turns on the inputs and their support in the record.

Where these cases are heard

Highest court: Illinois Supreme Court. Court system: illinoiscourts.gov.

Federal venues: Northern District of Illinois, Central District of Illinois, Southern District of Illinois.

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Illinois Workers' Compensation Commission.

Damages framework

Illinois pairs a wrongful death action for the pecuniary injuries to the spouse and next of kin, which now include grief and loss of society, with a survival action for the decedent's own claims, including earnings lost between injury and death. Recovery is barred once the plaintiff's fault exceeds half, the common-law collateral source rule applies with a post-verdict reduction procedure in medical malpractice cases, and prejudgment interest on personal injury and wrongful death awards now runs from the filing of the action.

Typical deliverables

We issue the final report and provide deposition and trial testimony, rebuttal of opposing economic reports, and recalculation when the life care plan or the medical record is updated.

Frequently asked: Personal injury economic damages analysis in Illinois product liability matters

How is personal injury economic damages analysis built for a product liability case in Illinois?

The same four steps apply to a product liability case venued in Illinois; 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 Illinois courts ask of personal injury economic damages analysis before it reaches the fact finder?

Illinois courts ask whether the methodology behind an expert opinion is generally accepted in the relevant professional community, and separately whether the economist is qualified by training and experience and applied the method to the facts of the case. Forensic economic methods for lost earnings, worklife, and present value are published and long used, so the examination usually turns on the inputs and their support in the record. Product Liability cases venued in Illinois are heard in the Circuit Court (General jurisdiction; 25 judicial circuits across the state, including the Circuit Court of Cook County), with final appeals to the Illinois Supreme Court. Matters within federal jurisdiction proceed in the Northern District of Illinois, Central District of Illinois, and Southern District of Illinois.

How does the Illinois damages framework shape personal injury economic damages analysis in a product liability case?

Illinois pairs a wrongful death action for the pecuniary injuries to the spouse and next of kin, which now include grief and loss of society, with a survival action for the decedent's own claims, including earnings lost between injury and death. Recovery is barred once the plaintiff's fault exceeds half, the common-law collateral source rule applies with a post-verdict reduction procedure in medical malpractice cases, and prejudgment interest on personal injury and wrongful death awards now runs from the filing of the action. 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 Illinois rules to a documented figure.
