Legal expenditure as a rent-seeking game

Legal expenditures at a civil trial constitute an interesting type of rent-seeking contest. In civil litigation there is a natural interaction between the objective merits of the case and the outcome of the contest. Institutions such as fee shifting do not generally have a counterpart in other rent-seeking contests. The endogenous decision to participate in the rent-seeking contest corresponds to the decision by the plaintiff to bring a case, and the decision by the defendant to defend it. The desirability of fee shifting is very sensitive to the value of the parameter which describes the legal technology.
