MNCs are extremely powerful institutions roaming the globe. They have major impacts on markets, social systems, and political institutions.

We believe more top managers of U.S. corporations, with help and prodding from government and strong activist critics, are exercising power responsibly. We continue this discussion of MNCs in the next chapter.
