We analyzed the factors determining the amount of the recovery on clai
ms based on medical malpractice. Our data set, which previously was no
t explored, consists of 20,428 claims arising within Michigan that wer
e closed between 1978 and 1990, During this period, major changes were
made in the law governing malpractice litigation. We determine the ef
fect of these changes and of various other factors affecting medical m
alpractice claims. We analyze the effect of a statute that was designe
d to curtail ''forum shopping'' by attorneys for plaintiffs. This stat
ute was initially successful in curbing such activity, but its effect
seems to be diminishing. In addition, we compare mediation awards with
settlement payments, and settlement payments with the expected value
of claims in litigation. Evidence suggests that a mediation award is t
he mediation panel's estimate of a settlement payment appropriate for
the case, and that cases are settled for substantially less than their
expected value at trial.
