This paper sheds new light on the assessment of firm networks via multiple directorships in terms of corporate firm performance. Using a large sample of European listed firms in the period from 2003 to 2011 and system GMM we find a significant compensation effect on corporate firm performance for the initial negative effect of horizontal multiple d...

We present a method for identifying up- and downstream industries in inter-industry datasets via input–output tables. We apply this approach to aggregated European input–output data and present results on identified industry links and their sensitivity to threshold definitions. We furthermore test the time-consistency of the up- and downstream assi...

We analyze empirically how supervisory board members with multiple directorships affect the decision to hire an inside or outside CEO successor. While a growing number of both theoretical and empirical studies analyze the influence of corporate performance and size or the ownership structure on this decision, the role of multiple board memberships...
