Chapter 8: Technological and Economic Mobility in Large German Manufacturing Firms
8. Technological and economic mobility in large German manufacturing ﬁrms Uwe Cantner and Jens J. Krüger1 INTRODUCTION The analyses reported in this chapter refer to the relationship between ﬁrm performance on the one hand and ﬁrm and industry evolution on the other. The empirical literature on this so-called industrial dynamics starts its analyses from a number of stylized facts related to structure and structural change (see Dosi et al. 1997). Among those structural factors, of considerable importance is the heterogeneity or asymmetry of ﬁrms which suggests a strongly idiosyncratic element in the technological performance of ﬁrms on the one hand and their economic performance on the other. The dynamics and evolution of an industry is then viewed as the result of these diﬀerent heterogeneities over time. There is some confusion in the recent literature on industrial dynamics about the amount of persistence or variability of certain variables like market shares or productivity measures over time. On the one hand, empirical studies such as those of Geroski and Toker (1996) on market shares or Jensen and McGuckin (1997) on relative labour productivity found considerable persistence of those measures. On the other hand, studies by Davies and Geroski (1997) or Mazzucato and Semmler (1999) concluded that market shares are rather unstable. Using patent data as measures of innovative activity in a statistical duration analysis, Geroski et al. (1997) conclude that very few ﬁrms innovate persistently over longer periods of time. The approach taken by Ceﬁs and Orsenigo (2001) is...
