document: The set of just-in-time management strategies : an assessment of their impact on plant-level productivity and input-factor substitutability using variable cost function estimates Many manufacturers in the automobile industry around the world have adopted the just-in-time -LRB- JIT -RRB- set of management strategies in an effort to improve productivity , efficiency and product quality . The paper provides empirical evidence that supports the idea that JIT manufacturing environments are , in fact , more productive than their non-JIT counterparts . Plant-level cross-sectional data from auto-parts manufacturing firms are used to estimate variable cost functions for a JIT group as well as for a non-JIT group of plants . Differences in cost function characteristics between the two groups are examined and discussed
