Using claim-level data, we estimate the effect of Texas's 2003 cap on noneconomic damages on jury verdicts, post-verdict payouts, and settlements in medical malpractice cases closed during 1988-2004. For pro-plaintiff jury verdicts, the cap affects 47-percent of verdicts and reduces mean allowed non-economic damages, mean allowed verdict, and mean total payout by 73-percent, 38-percent, and 27-percent, respectively. In total, the non-econ cap reduces adjusted verdicts by $156M, but predicted payouts by only $60M. The impact on payouts is smaller because a substantial portion of the above-cap damage awards were not being paid to begin with. In cases settled without trial, the non-econ cap affects 18-percent of cases and reduces predicted mean total payout by 18-percent. The non-econ cap Downloaded from 356 ~ Hyman, Black, Silver, Sage: Estimating the Effect of Damages Caps in Medical Malpractice Cases has a smaller impact on settled cases than tried cases because settled cases tend to involve smaller payouts. The impact of the non-econ cap varies across plaintiff categories. Deceased, unemployed, and (likely) elderly plaintiffs suffer a larger percentage reduction in payouts than living, employed, and non-elderly plaintiffs.We also simulate the effects of different caps and fi nd substantial differences in cap stringency across states. Different caps reduce aggregate payouts in tried cases (all cases) by between 16-percent and 65-percent (7-percent and 42-percent). Caps on total damages have especially large effects.
