This research aims to better understand the impact of the Matlab health interventions by using panel data to control for unobservables and understand the dynamics and long-term effects of these programs. Heterogeneity in the fertility response to the family planning program is analyzed, using sequential fertility to isolate the family planning program from other interventions and examine heterogeneity based on time-varying characteristics. The link between childhood measles vaccination and school enrollment is examined using instrumental variables, and is motivated by the hypothesis that by avoiding the long-term health effects of a disease, vaccinated children are higher-achieving. Both analyses generate interesting findings that are not captured using the traditional methodologies and outcomes of program evaluation.

Julia Driessen, PhD, is an assistant professor of health policy and management in the Graduate School of Public Health at the University of Pittsburgh. She has a secondary appointment in the Department of Economics. In 2011 Dr. Driessen received her PhD in Economics from Johns Hopkins University. Her research interests include program evaluation and the links between health interventions and socioeconomic status, with an emphasis on heterogeneity of program effects as well as long-term outcomes. Recent research has analyzed the schooling effects of childhood measles vaccination and variation in the fertility response to a family planning program in Bangladesh. Her primary new interest since arriving at Pitt is the clinical and financial effects of electronic medical records in developing countries.

Population aging in Asian societies is accompanied by changes in intergenerational living arrangements, which can have substantial health and economic implications for the elderly parents and their adult children. Dr. Young Kyung Do will present some of his recent works related to elderly living arrangements in South Korea. These works include the effect of coresidence with an adult child on depressive symptoms among older widowed women; the relationship between adult children's coresidence with parents and their labor force participation; and interrelations between expectations about bequests and informal care with special emphasis on the role of intergenerational coresidence. In these studies, Dr. Do attempted to account for a common methodological issue: living arrangements are not always randomly assigned but may be jointly decided with the outcome of interest taken into account by either the elderly parents or their adult children. While this seminar will focus on the South Korean context, the significance and implications apply to many other Asian societies undergoing population aging and marked transitions in elderly living arrangements.

Dr. Young Kyung Do is an assistant professor at the Duke-National University of Singapore Graduate Medical School (Duke-NUS), Program in Health Services and Systems Research. His research interests include the economic and health system impact of population aging and noncommunicable disease; interactions between self-care, informal care, and formal care interfaces; and health, education, and labor market outcomes over the life course. He received his MD (1997) and master of public health (2003) degrees from Seoul National University, subsequently completing his PhD in Health Policy and Management (2008) at the University of North Carolina at Chapel Hill. He was the inaugural Asia Health Policy postdoctoral fellow at the Shorenstein Asia-Pacific Research Center,(2008−9).

More than two decades have passed since the first case of HIV infection was detected in Cambodia in 1991. Cambodia is among the countries with the highest HIV prevalence in Asia and has been experiencing the most serious HIV/AIDS epidemic in the region. The epidemic is spread primarily through heterosexual transmission and revolves largely around the sex trade.

Since the beginning of the epidemic, the Royal Government of Cambodia has made a strong political commitment to the need for prevention of HIV transmission and care for people living with HIV/AIDS. It has received some technical and financial support from national and international agencies. Several prevention and intervention programs have been successfully implemented, and the WHO/UNAIDS recognized that the Cambodia’s HIV/AIDS epidemic appeared to have stabilized in 2002.

The estimated HIV prevalence in the general adult population declined to 0.5% in 2009, down from 1.2% in 2001. Among women visiting antenatal care clinics, the prevalence also declined from 2.1% in 1999 to 1.1% in 2006. There was also a gradual increase in the percentage of HIV-infected pregnant women who received antiretroviral therapy to reduce the risk of mother-to-child transmission, from 1.2% in 2003 to 11.2% in 2007, and finally to 32.3% in 2009.

Despite the decline of HIV prevalence in the general population, the prevalence remains high among high-risk groups such as commercial sex workers, men who have sex with men, and injection drug users. Furthermore, the so-called prevention-successful-country is also seeing the growing need for HIV/AIDS treatment and care.

This seminar will highlight the past and current features of Cambodia’s HIV/AIDS epidemic, lessons learned from prevention and care policies, and future challenges that Cambodia may face in the battles against HIV/AIDS.
