Abstract: The Type Indeterminacy model is a theoretical framework that uses some elements of quantum formalism to model the constructive preference perspective suggested by Kahneman and Tversky. In a dynamic decision context, type indeterminacy provides a framework for investigating the emergence and evolution of identity as the outcome of the interaction between multiple potential selves (eigentypes). We define a dynamic game among the selves with individual identity (preferences) as the state variable. In the Markov perfect equililibrium of the game, identity arises as "a relational property" that does not pre-exist the decision context. The approach allows to characterize generic personality types and derive some comparitive static results.
