Dr. Steward was retained to perform economic analysis in a personal injury lawsuit. Plaintiff was an undocumented worker from Mexico who migrated to the U.S. and was injured while working on the job. Dr. Steward determined that the plaintiff incurred economic losses to his earnings capacity as a result of the injuries he had sustained and household services he could have provided. The analyses of the plaintiff’s economic damages in this case were performed using two different work life scenarios. In the first scenario, Dr. Steward assumed that the plaintiff would have worked in the U.S. for a period of time and then return to Mexico had he not been injured. In the second work life scenario, he assumed that plaintiff would have worked in the U.S. over his entire expected work life. The present value of Mr. Lopez’ earnings and household services is derived by downwardly adjusting the annual earnings amount by an interest rate discount factor. In the analysis of earnings capacity, the economic damage period begins the date of plaintiff Lopez’ injury, and continues throughout his work life expectancy. In the analysis of household services, the economic damage period begins when plaintiff was expected to return to Mexico and continues throughout his life expectancy.
