Abstract
The present note corrects an error in the proof of Theorem 1 of Brandl et al. (2016). The proof for the case of [display formula] and [display formula] and the reduction of the case [display formula] to the case [display formula] are correct. However, the reduction of the case [display formula] to the case [display formula] is incorrect, since [display formula] as constructed in this step is not necessarily an extension of [display formula]. To fix this, let [display formula] be defined whenever for each agent, the set of his mostpreferred alternatives either is a singleton or contains all alternatives that are uniquely mostpreferred by some other agent. Additionally we require that at least one agent has a unique mostpreferred alternative. The lottery returned by [display formula] is obtained by choosing an agent with a unique mostpreferred alternative uniformly at random and returning that agent's mostpreferred alternative. With this definition of [display formula] the proof of Theorem 1 is correct. All other statements are unaffected. The authors thank Manuel Eberl for bringing this mistake to their attention.
