WebSignaling games are, however, also under special observation of pure game theorists not mainly driven by interests in economic or whatever applications. The point is that simple numerical examples for some signaling games reveal the weakness of certain equilibrium concepts, especially of the sequential equilibrium (Kreps & Wilson (1982)). This ...
