摘要：
The objective of this study is to analyze the relationship between innovation and performance for German firms that went public at the "Neuer Markt" during the period from 1997 to 2002. In the empirical analysis we investigate in particular whether initial public offerings (IPOs) with more or higher quality patents outperformed IPOs with lower quality or no patented technology. For this we measure the impact of patents on underpricing and long-run performance and explain the magnitude of these valuation effects with the Fama-French value and growth factors, with patent-specific variables such as the number of IPC-classes, family size, the number of backward and forward citations, as well as with industry variables. The empirical evidence suggests that patents are a reliable indicator for the success and the short- and long-run performance of start-up technology firms that went public and that the valuation effects are more pronounced for higher quality patents. © 2008 Swiss Society for Financial Market Research.
