19 Population Aging and the Future of Health Policy Comprehension Questions Indicate whether the statement is true or false,and justify your answer.Be sure to state any additional assumptions you may need. 1.Population growth in the developed world is contributing to population ag- ing. FALSE.In order for a population to exactly maintain its size fro n genera tion to generation,each woman must give birth to about 2.1 children over her lifetime.This special fertility rate is often called the population replace- ment fertility rate.In the last few decades,the total fertility rate in the devel- oped world has fallen below that level.Higher fertility rates in developing countries are actually slowing the aging of the world population 2.Japan's population is not aging along with the rest of the developed world. FALSE.Japan is the one of the starkes st e xamples of a population rapidly going gray.Indeed,the proportion of elderly in the Japanese population will increase at a far faster rate than in any other industrialized nation.Projec- tions indicate that 27.3 percent of the Japanese population will be over 65 by 2025,the one of the highest rates in the developed world. 3.In a world of population decline,many national health systems are not sol- vent because they were predicated on the assumption of population growth. 1

19 Population Aging and the Future of Health Policy Comprehension Questions Indicate whether the statement is true or false, and justify your answer. Be sure to state any additional assumptions you may need. 1. Population growth in the developed world is contributing to population ag￾ing. FALSE. In order for a population to exactly maintain its size from genera￾tion to generation, each woman must give birth to about 2.1 children over her lifetime. This special fertility rate is often called the population replace￾ment fertility rate. In the last few decades, the total fertility rate in the devel￾oped world has fallen below that level. Higher fertility rates in developing countries are actually slowing the aging of the world population. 2. Japan’s population is not aging along with the rest of the developed world. FALSE. Japan is the one of the starkest examples of a population rapidly going gray. Indeed, the proportion of elderly in the Japanese population will increase at a far faster rate than in any other industrialized nation. Projec￾tions indicate that 27.3 percent of the Japanese population will be over 65 by 2025, the one of the highest rates in the developed world. 3. In a world of population decline, many national health systems are not sol￾vent because they were predicated on the assumption of population growth. 1

2 Health Economics Answer Key TRUE.Many of these health systems are predicated on a bedrock assump ed reas sonable up until the last f ever the twin forces of rising life expectancy an declining birthrates will bankrupt these programs unless they are reformed 4.In recent years,each years'Medicare tax receipts have been sufficient to cover that year's services on behalf of enrollees. FALSE.I007,Medicare Part A expenditures exceeded payroll tax collec tions for the first time,and the Medicare Trust Fund has been on the decline since then. 5.In the 1970s,researchers were worried that,while Americans were living longer than previous generations,they were actually less healthy during old age than before.This phenomenon is known as the "compression of morbid- ity." FALSE.This findi vidence agai compre ion of morbidity,which oc- curs when disability and illness are delayed until later in life 6.Reducing mortality from one disease necessarily increases the sum of the to- tal mortality risk from all other causes of death TRUE.The inevitable rise in mortality from other causes that results from a reduction in mortality from any one particular cause is known as the competing risks problem 7.If a costless drug were created that effectively cured a prevalent and deadly disease,health care expenditures would decrease. FALSE.For example,overall health care expenditures might rise as a con- sequence of a new magical cancer treatment,even if the treatment itself is basically costless.This might occur if the costs of caring for heart attacks and other competing risks are more expensive than caring for cancer 8.Disproportionate spending on end-of-life care is never clinically justifiable FALSE.Some end-of-life health care is wasteful or even prolongs the pain of a dying patient,but in many cases,disproportionate spending on EOL of a cancer.

2 | Health Economics Answer Key TRUE. Many of these health systems are predicated on a bedrock assump￾tion of population growth, which seemed reasonable up until the last few decades. However the twin forces of rising life expectancy and declining birthrates will bankrupt these programs unless they are reformed. 4. In recent years, each years’ Medicare tax receipts have been sufficient to cover that year’s services on behalf of enrollees. FALSE. In 2007, Medicare Part A expenditures exceeded payroll tax collec￾tions for the first time, and the Medicare Trust Fund has been on the decline since then. 5. In the 1970s, researchers were worried that, while Americans were living longer than previous generations, they were actually less healthy during old age than before. This phenomenon is known as the “compression of morbid￾ity.” FALSE. This finding is evidence against compression of morbidity, which oc￾curs when disability and illness are delayed until later in life. 6. Reducing mortality from one disease necessarily increases the sum of the to￾tal mortality risk from all other causes of death. TRUE. The inevitable rise in mortality from other causes that results from a reduction in mortality from any one particular cause is known as the competing￾risks problem. 7. If a costless drug were created that effectively cured a prevalent and deadly disease, health care expenditures would decrease. FALSE. For example, overall health care expenditures might rise as a con￾sequence of a new magical cancer treatment, even if the treatment itself is basically costless. This might occur if the costs of caring for heart attacks and other competing risks are more expensive than caring for cancer. 8. Disproportionate spending on end-of-life care is never clinically justifiable. FALSE. Some end-of-life health care is wasteful or even prolongs the pain of a dying patient, but in many cases, disproportionate spending on EOL care is clinically justifiable, as in the case of emergency surgery for patients with badly clogged arteries or chemotherapy capable of arresting the spread of a cancer. ￾c Bhattacharya, Hyde & Tu 2013 2

FALSE.Natalist policies have enjoyed limited success in France and Sweden, but most European countries still have very low birth rates. 3 Bhattacharya,Hyde &Tu013

Chapter 19| Population Aging and the Future of Health Policy | 3 9. Advance directives allow patients to indicate their own preferences about EOL care, but they cannot be acted upon if a dying patient is too sick to com￾municate with doctors. FALSE. An advance directive is a binding legal document that indicates a patient’s wishes regarding end-of-life care. The patient can specifically indi￾cate instructions for situations in which he can no longer communicate. 10. Aggressive natalist policies have successfully reversed birth rate declines in most European countries. FALSE. Natalist policies have enjoyed limited success in France and Sweden, but most European countries still have very low birth rates. 3 ￾c Bhattacharya, Hyde & Tu 2013
