Input‐Price Risk Management: Technology Improvement and Financial Hedging
研究了技术改进（如节能项目）在管理投入品价格风险中的作用，通过数学模型量化企业面对价格不确定性的态度，并比较了技术改进与金融对冲的风险管理优势及互补性。
We study the merits and limitations of technology improvement (TI) initiatives for managing input–price risk. Such initiatives (e.g., energy efficiency projects) typically reduce the consumption of an input commodity and so result in lower production costs, more sustainable operations, and/or an improved competitive position. This study explores whether TI can also serve to hedge risks. Although TI clearly reduces both average cost and risk exposure, some firms may actually benefit from input–price uncertainty; the result, when combined with production flexibility, is an “option value” that firms may well be reluctant to forgo. We develop a stylized mathematical model to examine the incentives of different types of firms to adopt TI. Thus, we derive a closed‐form expression that quantifies a firm’s attitude toward input–price risk by considering the firm’s certainty premium, or what the firm would pay to “lock in” the unit input price, and then link that premium to various firm‐ and industry‐specific characteristics. We also compare the risk management advantages of technology improvement vs. financial hedging (FH) and give conditions under which these strategies are complements or substitutes. Our results show that, even when input‐price uncertainty is desirable for firms, they can still benefit from investing in risk reduction measures—such as TI and FH—because the uncertainty’s option value could thereby increase. A firm’s ability to adjust its price in response to both market competition and input‐price variation mediates the benefit of risk‐reducing measures and also affects the complementarity of these two strategies.
