Global Health Economics: Checkpoint 1

Quick checkpoint - five questions on health improvements, financing, Gavi, HIV and polio.

Question 1 of 5 What did Samuel Preston's research show about health and income?

Health improves only when income rises At any given income level, life expectancy rose over time as knowledge spread Richer countries always have worse health Income has no link to health

Spreading knowledge and technology made health cheaper to achieve.

Question 2 of 5 In most middle-income countries like India, what is the main source of health financing?

Foreign aid Domestic government and household spending Philanthropy only International loans

Aid is important in the poorest countries, but domestic spending dominates elsewhere.

Question 3 of 5 How does Gavi help lower vaccine prices?

By manufacturing all vaccines itself By pooling demand from many countries and negotiating large, predictable orders By banning private companies By taxing vaccine makers

Pooled procurement provides scale and bargaining power.

Question 4 of 5 What cut the cost of HIV treatment dramatically in the early 2000s?

New taxes Competition from Indian generic manufacturers A global ban on patents Shorter treatment courses

Generic combinations brought costs from over 10,000 dollars to under 100 dollars a year.

Question 5 of 5 Why is the last mile of polio eradication considered worth its high cost?

Because the vaccine is free Because eradication removes the disease permanently, so its benefits last forever Because polio only affects adults Because it raises tax revenue

Unlike control, eradication allows spending to stop eventually, as with smallpox.
