The Risks of Malpractice Cases
The pattern of returns lawyers obtained in medical malpractice cases 
highlights the relationship between risk and effective hourly rates. One 
of the observed lawyers was working on a large medical malpractice case. 
At one point we worked through the likely outcomes of the case and their 
probabilities (these ranged from a 50 percent chance of getting nothing 
to a 10 percent chance of getting $8 million). We estimated that his 
"expected" fee was $500,000 (although his actual fee could range as high 
as $1.7 million under the rules governing legal fees in medical 
malpractice cases in Wisconsin). Given the amount of time the lawyer had 
devoted to the case, and what was yet to come, we estimated that while 
he might make as much as $1,100 per hour, his expected effective hourly 
rate was $330.
When later examining the 40 medical malpractice cases in the sample 
from the survey, the median effective hourly rate was only $38, which is 
what is shown in Figure 1. 
However, this rate reflected in part that 45 percent of the medical 
malpractice cases resulted in no payment at all. The maximum effective 
hourly rate reported was $2,900; and 10 percent of the cases had 
effective hourly rates of $1,000 or more. The mean effective hourly rate 
was $334, and the aggregate effective hourly rate across all 40 cases 
was $338 per hour. Medical malpractice work produces a very good return 
on the investment of the lawyer's time, but a lawyer faces some very 
substantial risks in undertaking this work.
