Risk aversion plays an important role in explaining why antitrust case
s settle instead of going to trial. Using a jointly estimated model of
settlement and trial outcome, we find that a 1% increase in the proba
bility that the plaintiff wins at trial raises the probability of a se
ttlement by 0.13%. We also find that reputation effects are not a sign
ificant factor for defendants, so the risk aversion of the defendants
does not play a dominant role in determining whether the parties settl
e. Plaintiffs are more likely to win in certain jurisdictions, which e
ncourages venue shopping by plaintiffs.
