The widespread addition of antibiotics to animal feed helps animals grow faster and remain healthy, despite living in crowded industrial farming operations. Bacteria in these farming operations vulnerable to antibiotics die off; bacteria that mutate to become resistant to antibiotics survive. Suppose there is a global pandemic caused by antibiotic resistant bacteria that attacks humans. The prisoner's dilemma is a theory that shows why two completely rational individuals might not cooperate, even if it appears that it is in their best interests to do so. Explain whether, and if so how and why, prisoners' dilemma problems shape the capital investment strategies of farms, animal feed makers, and pharmaceuticals companies if the stock market is semi-strong form efficient. Please answer in detail.
