Consistent with economic theory, markets respond to failures by developing structures that fill the gaps resulting from such failures3 examples of such structures in the us include: independent physicians, cost-based reimbursement for hospitals and managed care20 to some degree, health insurance is a structure that covers market failure due. The efficient market theory (emt) suggests that all relevant information is known and factored into the current price of stocks not only that, but any new information has been factored into the price before an investor can learn of the information and act on it.
