Abstract

This study investigates the effect of internal labor markets (ILMs) on corporate innovation, focusing on Korean chaebols. Prior to examining the effect of ILMs, we confirm their efficiency, finding that chaebol firms with lower (higher) growth opportunity exhibit higher (lower) subsequent labor outflows. Further, ILM efficiency is more pronounced for firms within a more diversified chaebol, those whose controlling shareholder has lower equity stakes, and during a financial crisis period. We then investigate the effect of ILMs on innovation. We find that ILM efficiency leads affiliated firms to show greater innovative performance. Moreover, this positive influence is more pronounced for firms that receive internal capital. Overall, our study suggests the importance of ILMs in promoting corporate innovation among group firms.
