We extend the standard finance model of the firm's dividend/investment/financing decisions by allowing the firm's managers to know more than outside investors about
the true state of the firm's current earnings. The extension endogenizes the dividend
(and financing) announcement effects amply documented in recent research. But once
trading of shares is admitted to the model along with asymmetric information, the
familiar Fisherian criterion for optimal investment becomes time inconsistent: the
market's belief that the firm is following the Fisher rule creates incentives to violate
the rule.
