Continuous-time Games of
Timing

The present paper addresses the question of
existence of equilibrium in timing games with trivial filtration. It provides a framework that unifies the
specific classes of timing games discussed in the literature. Moreover, it deals with the question of
equilibrium existence in many timing games that have not been studied before.
Our first result is a general existence result for two-player
games: assuming payoffs are continuous and
bounded, the game has a subgame-perfect epsilon-equilibrium, for each positive epsilon.
For some classes of economic interest, we obtain stronger existence results. For symmetric games, our existence result is valid irrespective of the number of players, and the corresponding strategy profile is pure - but a symmetric epsilon-equilibrium need not exist.
We also address the issue of the existence of a Markov subgame-perfect epsilon-equilibrium, and we provide an example for the non-existence of an equilibrium in a three-player game.
