Abstract:
In this paper, the author considers a risk-neutral competitive firm which is uncertain about the true state of demand. He builds upon K. J. Arrow (1968) by demonstrating that the irreversibility of investment in physical capital together with the anticipation of receiving information and of learning the state of demand lead to (1) cautious investment behavior and, hence, to lower investment levels; (2) a time-varying risk premium or marginal "adjustment cost"; and (3) a gradual adjustment of the capital stock to the desired level.
