How the value of information shapes the value of commitment or why the value of commitment does not vanish

This paper challenges recent results on the fragility of the value of commitment. It introduces a specific notion of the 'value of information' for a later-moving player about the action choice of a previously-moving player, gives conditions under which this value is positive and shows that a positive value of information for the latermoving player is sufficient for a positive value of commitment for the previouslymoving player. It then argues that the value of information for a later-moving player is unlikely to vanish in real-world applications, implying that the value of commitment for the previously-moving player does not vanish either.
