Many anecdotes suggest that competing Japanese firms tend to adopt similar behavior. In this paper, we perform two differenuests to explore similarities in firm behavior and market structure in Japan. The first test shows that firm sizes are more similar in Japan than in the US, while there is no difference in market concentration between the two countries. The second test relates to market share stability, which is a proxy for similar behavior. Prior studies have regarded market share stability as a result of collusion. If so, market share stability should be positively correlated with market concentration which promotes collusion. In contrast, if similar behavior stems from competitive interaction and mimetic isomorphism, market share stability should be positively correlated with firm size similarity reflecting similarity of firm capabiliIies and characteristics. W¢find that market share stability in Japan has a strong and positive association with firm size similarity, while it has no significant relationship with market concenIration. These results suggest that Japanese firms tend to take similar behavior stemming not from collusion but from competition.
