KW Economics prepares lost earnings analysis for medical malpractice cases venued in South Dakota: what the loss claim consists of, the records that drive it, and a present value built to South Dakota damages rules and venues. Plaintiff and defense.
In a medical malpractice matter the lost earnings claim is measured against the outcome the patient would have had with proper care, not against perfect health. The economist takes the causation and prognosis opinions in the record as the baseline, states the but-for earnings path they support, and builds the injured path from actual post-injury earnings and the work-capacity opinions. The loss is the difference between the two paths, projected over the applicable worklife with growth and discounted to present value. Where the underlying condition would have limited work on its own, the apportionment between the injury and the condition is usually the assumption that most changes the total.
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.
Because the underlying condition often affected work capacity or life expectancy on its own, the apportionment between the injury and the pre-existing condition is usually the most contested assumption and the one that most changes the total. In cases of permanent disability the incremental care costs and the earnings loss are both large and run across a long horizon, and the life expectancy used for each stream is a second point of contention. In delayed-diagnosis cases the loss may be measured as the difference between two outcome paths, each with its own earnings and care profile.
South Dakota courts screen expert testimony for reliability: the trial 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. A damages report is written to that standard, with each data series named and each assumption tied to the record.
Highest court: South Dakota Supreme Court. Court system: ujs.sd.gov.
Federal venues: District of South Dakota.
Outside the civil courts, wage-loss disputes in workers' compensation matters proceed before the South Dakota Department of Labor and Regulation, Division of Labor and Management.
South Dakota provides a wrongful death action for the pecuniary injury to the surviving spouse, children, or next of kin, which the courts read to include loss of companionship and society, alongside a survival action for the estate. The state's unusual comparative negligence rule allows recovery only when the plaintiff's negligence was slight in comparison with the defendant's, the common-law collateral source rule applies, and prejudgment interest is allowed on past damages but not on future damages, punitive damages, or intangible losses.
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 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 South Dakota rules to a documented figure.
