This Q&A ran as a companion piece to a broader article on globalization by the Detroit Free Press reporter Sarah Webster. Peter Henning is quoted in both pieces. General Motors Corp.'s largest individual shareholder, Kirk Kerkorian, is pushing GM to consider having France's Renault and Japan's Nissan Motor Co. buy a significant stake in the company to form a three-way global alliance. Professor Peter Henning commented about the consequences of this potential alliance. He said with shares of large companies fractured, it usually takes consolidated control of only about a third of a company's shares to have power over the direction of the company.
