Bp, one of the world's largest oil companies, has made it part of the company policy to undertake "social investments" in the countries where it does business. there was no economic reason for bp to make this social investment, but the company believes it is morally obligated to give something back to the societies that have made their success possible. bp's actions are an example of: the friedman doctrine. cultural relativism. the tragedy of the commons. noblesse oblige.
