This book lays out a range of policy actions that are needed at the various phases of the demographic transition and uses global and regional experiences to provide evidence on what has worked and what has not. Countries have a menu of options available to speed up the transition, improve...

Declines in child mortality, followed by declines in fertility, produce a youth bulge generation and a period when a country has a large number of working age people and a smaller number of dependents. If gainfully employed, a large number of workers per capita gives a boost to the economy. The...

Assuming individual preferences satisfy the Von Neumann-Morgenstern axioms for expected utility we show how we can measure an individual's expected utility of any state using their willingness to accept a gamble over two reference points. The utility function captures the diminishing marginal...

Selection bias in HIV prevalence estimates occurs if non-participation in testing is correlated with HIV status. Longitudinal data suggests that individuals who know or suspect they are HIV positive are less likely to participate in testing in HIV surveys, in which case methods to correct for...

The causes and consequences of the demographic transition are considered in light of the recent book by Dyson (2010) on demography and development. In the last 50 years the world has seen an exogenous decline in mortality that generated a decline in fertility and an increase in urbanization that...

Health is a key component of human development. This paper looks at how health is measured, and the convergence of health across countries. We argue that health measures should account for illness as well as mortality, but in practice life expectancy as a reasonably proxy for population health....

We investigate the effects of ante-natal maternal vaccination against tetanus on the schooling attained by children in Bangladesh. Maternal vaccination prevents the child from acquiring tetanus at birth through blood infection and substantially reduces infant mortality and may prevent impairment...

We estimate the effect of malaria on settlement and land use patterns in the Brazilian Amazon, where potential settlers were randomly assigned to plots in a newly opened settlement area. The random assignment allows us to estimate the risk of malaria on each plot based only on its...
