The paper addresses the LIFO/FIFO choice issue in the context of a signaling model. It offers an explanation of why some firms choose FIFO and others LIFO. In the model the firm manager has private information about firm quality, where quality refers to the distribution of future cash flows and therefore to the likelihood of bankruptcy. Firms with better prospects can signal high quality by choosing FIFO. This, in turn, increases the current market value of good firms, and, since management compensation is at least partially determined by firm value, management is better off. In this way FIFO is a rational choice for the management of good firms even though tax (and, hence, cash-flow) benefits are associated with LIFO. In an incomplete information setting there is always a potential for a deadweight loss whenever some of the players have incentives to withhold their private knowledge-that is, they will not divulge it for free. In this model, the foregone tax benefits of choosing FIFO are a deadweight loss. Low-quality firms are reluctant to disclose their type. Hence, the highquality firms are willing to explore costly options to identify themselves publicly. The specific mechanism by which high-quality firms identify themselves is that they forego the tax benefits associated with LIFO. This, in turn, makes it more likely that the firm will be unable to meet its debt repayment requirements and incur a bankruptcy cost. For a separating equilibrium to exist, FIFO must be more costly for low-quality firms than for high-quality firms. Otherwise, the low-quality firms would mimic the high-quality ones and capture the same benefits.
