Which governance model(s) across geographical borders do you perceive to provide the best basis for company growth and value-creation, and why?
No one particular governance model is better suited than any other. The governance models, in practice, reflect the political mindset and political nature of the country in which they sit.
Germany is one of the most successful economies and their two-tier board structure would, on this basis, be suitable for greater global application.
However, that is unlikely as the German political structure reflects the socialized capital nature of the German state. The German economy has one of the smallest stock exchanges in the world and the German government more relies on the debt market i.e. investors purchasing government bonds, rather than speculating in the equities market.
Thus, the more communal nature and concern for the citizens, which is at the centre of German politics, is reflected in the two-tier board structure with the supervisory board more taking into account broader stakeholder opinions than would their Anglo-American counterparts.
In contrast, the Anglo-American model reflects the short-term transactional nature of the Anglo-American states, where ensuring that investors are properly treated by management is the critical concern. No one model is best as the question more reflects geopolitical reality rather than governance.
