[Abstract]
This research provides empirical evidence on the employment effect of both process and product innovations under different market structures, using data from 1999 to 2009 on 11,369 manufacturing firms in Korea. Consistent to the literature, it first finds that the overall employment effect of innovations is positive, since process innovations do not have any significant effect but product innovations have positive and significant effects on employment. Then, our contribution is to estimate the employment effect of innovations in different market structure by adding interaction terms between proxies for market structure and each type of innovation. We find that process innovation has a greater negative effect in more monopolistic markets, and confirm no significant differences in the employment effect of product innovations across different market structure. Overall, we show that innovations have different effects on employment across different market structures, which implies that a competitive market is important for increasing employment through innovation.
