Collective contests with externalities: corrigendum

Sanghack Lee and J. Hyeong Kang [Eur. J. Polit. Econ. 14 (1998) 727-738] analysed externalities in group contests. The contest in their paper is modelled as a two-stage game. In the first stage, an intragroup sharing-rule parameter is chosen such that the group's aggregate payoff is maximised. In the second stage, each participant in the contest decides about his or her payoff-maximising outlay. The outlays in the group contest are compared to the outlays in an comparable individual contest. The authors derived incorrect results based on an arithmetic error in Eqs. (17) and (18) on page 735. In this corrigendum, the correct results are presented.
