We study games with uncertainty about the existence of competitors (ghosts). Such a set-up is well-suited for example for online auctions, or in the context of real options with investors who do not want to reveal their interest in a certain business opportunity. We first discuss non-dynamic versions of the game (auctions), and then we generalise to ghost games of optimal stopping type (real options) where we derive a Nash equilibrium in randomized stopping times which is described explicitly in terms of the corresponding one-player game.

This is joint work with Tiziano De Angelis.
