Marginal Cost/Benefit Decisions and the Investment Industry Watch video: DRUG SHORT ON NETFLIX in the Dirty Money Series (Series 1)This activity is meant to be used once Marginal Cost, Marginal Benefit and Diminishing Marginal Utility and Investing (short selling) are taught. The movie "Drug Short" is part of the Dirty Money Series 1 on Netflix. Underlying issues in this case are greed, ethics, corporate profit and efforts to maximize shareholder profit at all costs (even human life). This activity looks at the activites of pharmaceutical companies and their efforts to make money, yet disregarding the impact on people who rely on the medicine. Short seller investors "sold the stocks" of drug companies when the prices were high, predicting that there was unethical activities which would eventually bring the share price down. Short sellers make money by expecting share prices to fall, when they identify bad companies or unethical behavior (which is exactly what happened here).
