Inventory and Corporate Risk Management
研究了企业如何通过持有库存来对冲投入品价格风险，发现库存能平滑资本投资，且储蓄增强这种对冲效果，实证基于美国制造业企业数据。
We consider a dynamic model of investment in which a firm can hold inventory to mitigate the price risk of an input commodity. Our model predicts that inventory hedges against net worth risk by smoothing investment in capital, regardless of the level of current net worth. Savings enhance the operational hedge offered by inventory, because they better conserve net worth when the commodity price is low. These predictions are confirmed in a sample of U.S. manufacturing corporations. We find that the empirical sensitivity of inventory investment to price changes is positive for any level of firms’ net worth. Savings and inventory are both positively related to financing constraints and cash-flow risk, but investment is more sensitive to inventory.
