Demand for nondurable goods: a shortcut to estimating long‐run price elasticities
提出一个包含消费者库存的动态需求模型，并给出一个无需解动态规划就能估计长期价格弹性的捷径。利用法国家庭食品购买数据，得到的弹性与文献中完整估计的结果一致。
When consumers stockpile, static demand models overestimate long‐term price responses. This article presents a dynamic model of demand with consumer inventories and proposes a shortcut to estimate the long‐run price elasticities without having to solve the dynamic program. Using French data on food purchases, I find elasticities consistent with those that result from the full‐blown estimations found in the literature.
