Abstract: | This paper uses a data base of quantitative and qualitative plant-level cross-sectional data to analyze the relative performance of Just-in-time (JIT) and non-JIT plants operating in two distinct manufacturing industries: electronic components and auto-parts. A number of conjectures made by the literature concerning the relationship between JIT manufacturing and plant inventory holdings, costs and profits are tested. Consistent with many of these conjectures, the results suggest that JIT manufacturing at the plant level is associated with greater productivity in inventory usage, lower total and variable costs, but not fixed costs, and higher profits. The success of JIT plants along these dimensions is found to be related to the length of experience with JIT manufacturing, and process quality and leanness but unrelated to product quality, quality control or the extent of plant unionization. |
