The students learn how government regulation of financial markets is intended to protect investors from fraud and prevent market failure. They also learn how regulatory efforts may be weakened or negated by government failure. In addition to the possibilities of market failures and government failures, students are shown that businesses sometimes lose money because of inherent risk and not because of any wrongdoing. Students consolidate their learning by playing a ñblame game,î applying distinctions between government failure, market failure, and no failure.
