Kinship systems in China, the Republic of Korea, and North India have similar features that generate discrimination against girls, and these countries have some of the highest proportions of girls"missing"in the world. The authors document how the excess mortality of girls was increased by war,...

The apparently inexorable rise in the proportion of"missing girls"in much of East and South Asia has attracted much attention amongst researchers and policy-makers. An encouraging trend was suggested by the case of South Korea, where child sex ratios were the highest in Asia but peaked in the...

The apparently inexorable rise in the proportion of "missing girls" in much of East and South Asia has attracted much attention among researchers and policymakers. An encouraging trend was suggested by the case of South Korea, where child sex ratios (males to females under age 5) were the...

In China, marriage is still a highly valued social norm, and until the 1990s, practically everyone was able to marry. The situation has changed, however, and a rising proportion of men, in rural areas especially, will experience prolonged and even permanent singlehood due to the growing shortage...

Sex ratios at birth rose sharply in the South Caucasus countries after 1991, but recent data indicate that this trend is turning. What caused this rise, and what can be done to accelerate its normalization? Traditional kinship systems in the region are similar to those of other settings with...

The authors study the impact of governance and administrative factors on communicable disease prevention in the Indian state of Karnataka using survey data from administrators, frontline workers, and elected local representatives. They identify a number of key constraints to the effective...

For years, South Korea presented the puzzling phenomenon of steeply rising sex ratios at birth despite rapid development, including in women's education and formal employment. This paper shows that son preference decreased in response to development, but its manifestation continued until the...

Violent conflict, a pervasive feature of the recent global landscape, has lasting impacts on human capital, and these impacts are seldom gender neutral. Death and destruction alter the structure and dynamics of households, including their demographic profiles and traditional gender roles. To...

Aid to developing countries has largely neglected the population-wide health services that are core to communicable disease control in the developed world. These mostly non-clinical services generate"pure public goods"by reducing everyone's exposure to disease through measures such as...

China has a large deficit of females, and public policies have sought to reduce the son preference that is widely believed to cause this. Recently a study has suggested that up to 75 percent of this deficit is attributable to hepatitis B infection, indicating that immunization programs should...
