Two possible inefficiencies may arise: (i) uniform adoption, i.e., all individuals choose the action that is optimal for one type but sub-optimal for the other, or (ii) dual incomplete learning, i.e., only a fraction of each type chooses its optimal action. Which one occurs depends on the composition of the population and how critical the choice is for different types of individuals. In an application, we show that a monopolist serving …
