  We examine vote delegation when preferences of agents are private
information. One group of agents (delegators) does not want to participate in
voting and abstains under conventional voting or can delegate its votes to the
other group (voters) who decide between two alternatives. We show that free
delegation favors minorities, that is, alternatives that have a lower chance of
winning ex-ante. The same occurs if the number of voting rights that actual
voters can have is capped. When the number of delegators increases, the
probability that the ex-ante minority wins under free and capped delegation
converges to the one under conventional voting--albeit non-monotonically. Our
results are obtained in a private value setting but can be readily translated
into an information aggregation setting when voters receive a signal about the
''correct" alternative with some probability.
