When there is asymmetric information, contingent fees can allow client
s to signal the qualities of their cases and attorneys to signal the q
uality of their advice. Thus, a well-informed client who has a high-qu
ality case will be willing to pay a relatively high fixed fee and a re
latively low contingency percentage, while a client with a low-quality
case will prefer a low fixed fee and a high contingency percentage. I
n contrast, a well-informed high-quality attorney will signal her abil
ity by working for a relatively high contingency percentage.
