Modeling and mitigating supply chain disruptions as a bilevel network flow problem

Ralf Seifert, Anna Timonina-Farkas, René Yves Glogg

Years of globalization, outsourcing and cost cutting have increased supply chain vulnerability calling for more effective risk mitigation strategies. In our research, we analyze supply chain disruptions in a production setting. Using a bilevel optimization ...

Former CEO Directors: Lingering CEOs or Valuable Resources?

Rüdiger Fahlenbrach

We investigate corporate governance experts' claim that it is detrimental to a firm to reappoint former CEOs as directors after they step down as CEOs. We find that more successful and more powerful former CEOs are more likely to be reappointed to the boar ...

Do firms know the scope of their R&D network? An empirical investigation of network awareness on French survey data

Stéphane Lhuillery

Although research and development (R&D) networks influence the innovation performance of their members, firms may not be fully aware of the scope of their network. In particular, due to cost reasons, they may not be fully informed of their “indirect ties”, ...
