JIT performance effects: A research note

This paper uses a sample of 131 just-in-time (JIT) firms and their matched non-JIT firms to examine whether adoption of JIT improves firm performance. Tobin's Q and return on assets (ROA) are used to measure firm performance. Overall, the results indicate that statistically significant differences in Tobin's Q and ROA were observed in a pre- and post-test of JIT adopters and between matched non-JIT adopters.
