KW Economics prepares lost earnings analysis for traumatic brain injury cases venued in Illinois: what the loss claim consists of, the records that drive it, and a present value built to Illinois damages rules and venues. Plaintiff and defense.
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.
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.
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.

Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the Illinois Workers' Compensation Commission.
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.
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.
The same four steps apply to a traumatic brain injury case venued in Illinois; 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.

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. Traumatic Brain Injury 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.
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.
