摘要：The authors explore the economics of health and development,
arguing that new evidence coupled with a wider perspective suggest sizable
economic returns to better health. Drawing on studies of human welfare, they say
that past estimates of economic progress have been understated and that recent
economic losses caused by HIV/AIDS are likewise being understated if economists
rely on GDP per capita as a yardstick. A better indicator is "full income"—an
assessment of economic welfare that captures both the value of changes in life
expectancy and income as measured in national accounts. For Africa, they say,
this new yardstick "signals catastrophe ahead."
