Corporate citizenship is now a model for twenty-first century corporate governance. Through a model of corporate citizenship involving "four faces," connoting the economic, legal, ethical, and discretionary components, firms are expected to meet their social responsibilities. This corporate citizenship approach to social responsibilities has acquired recent national institutional legitimacy though private-public partnership initiatives. The institutional forces, while not yet matching or superceding the "technical" efficiency forces, show evidence of being further strengthened by the various private-public partnerships. The discretionary responsibilities "face" has evolved into strategic philanthropy with firm discretionary resources being employed to competitive advantage. One potential area of concern is delineating where the corporation's social responsibilities stop and where government's role begins.
