Taking Stock: A Critical Assessment of Recent Research on Inventories
回顾了1950年代以来库存研究的演变，指出宏观与微观视角的张力，并聚焦于标准生产平滑/缓冲库存模型陷入困境后的新发展。
Empirical and theoretical aspects of inventory behavior became hot topics in the 1950s and early 1960s. No one seemed to notice the tension that was developing between the emerging macroeconomic and microeconomic views of inventories. Macroeconomists routinely thought of inventories as a destabilizing factor, yet the prevailing micro theory viewed inventories as a stabilizing factor. It was a fascinating question that was barely explored. Instead somewhat inexplicably, interest in inventories dried up, as if inventories were of minor economic significance and little intrinsic interest. By the early 1980s, then, economists once again knew something they had known in the 1950s: that inventory investment is of first-order importance in business cycles. But they were also beginning to realize that the standard production-smoothing/buffer-stock model of inventories was in deep trouble. This paper focuses on developments since that realization.
