The Role of a Variable Input in the Relationship Between Investment and Uncertainty
指出，Caballero（1991）认为不确定性只增加完全竞争且规模报酬不变企业的投资，但本文证明一次性固定成本产生的期权价值可能导致不确定性增加反而使投资从正值降为零。
Caballero (1991) shows that a larger uncertainty only increases the investment of a perfectly competitive firm with a constant returns to scale technology. We show, however, that the option value generated by a one-time fixed cost can cause the increasing uncertainty to reduce investment from a positive value to zero.
