Discuss the change in the infant mortality rate (IMR) in the United States since 1960. Do you think the IMR is too high in the United States? Why? Determine the implication of a reduction in the IMR if we IMR reductions as one good on one axis of the PPC and all other goods on the other axis? Find out the implication of an IMR reduction if we assume some production inefficiency initially exists in the U.S. health care system? Why?
