Biography
Damien de Walque received his Ph.D.in Economics from the University of Chicago in 2003. His research interests include health and education and the interactions between them. His current work is focused on evaluating the impact of financial incentives on health and education outcomes. He is currently evaluating the education and health outcomes of conditional cash transfers linked to school attendance and health center visits in Burkina Faso. He is also working on evaluating the impact of HIV/AIDS interventions and policies in several African countries. He is leading two evaluations of the impact of short-term financial incentives on the prevention of HIV/AIDS and other sexually transmitted infections (STIs): individuals who test negatively for a set of STIs receive regular cash payment in Tanzania, while in Lesotho they receive lottery tickets. On the supply side of health services, he is managing a large portfolio of impact evaluations of results-based financing in the health sector. He has also edited a book on risky behaviors for health (smoking, drugs, alcohol, obesity, risky sex) in the developing world.

Using Provider Performance Incentives to Increase HIV Testing and Counseling Services in Rwanda
(World Bank, Washington, DC, 2013-02)Paying for performance provides financial rewards to medical care providers for improvements in performance measured by specific utilization and quality of care indicators. In 2006, Rwanda began a paying for performance scheme to improve health services delivery, including HIV/AIDS services. This study examines the scheme's impact on individual and couples HIV testing and counseling and using data from a prospective quasi-experimental design. The study finds a positive impact of paying for performance with an increase of 6.1 percentage points in the probability of individuals having ever been tested. This positive impact is stronger for married individuals: 10.2 percentage points. The results also indicate larger impacts of paying for performance on the likelihood that the respondent reports both partners have ever been tested, especially among discordant couples (14.7 percentage point increase) in which only one of the partners is HIV positive. -

Parental Education and Children’s Schooling Outcomes : Is the Effect Nature, Nurture, or Both? Evidence from Recomposed Families in Rwanda
(World Bank, Washington, DC, 2005-01)Educated parents tend to have educated children. But is intergenerational transmission of human capital more nature, more nurture, or both? The author uses household survey data from Rwanda that contains a large proportion of children living in households without their biological parents. The data allows him to separate genetic from environmental parental influences. The nonrandom placement of children is controlled by including the educational attainment of the absent biological parents and the type of relationship that links the children to their "adoptive" families. The results of the analysis suggest that the nurture component of the intergenerational transmission of human capital is important for both parents, contrary to recent evidence proposed by Behrman and Rosenzweig (2002) and Plug (2004). The author concludes that mothers education had no environmental impact on children s schooling. Interestingly, mothers education matters more for girls, while fathers education is more important for boys. Finally, an important policy recommendation in the African context emerges from the analysis: the risk for orphans or abandoned children to lose ground in their schooling achievements is minimized if they are placed with relatives. -

Discordant Couples : HIV Infection Among Couples in Burkina Faso, Cameroon, Ghana, Kenya, and Tanzania
(World Bank, Washington, DC, 2006-06)Most analyses of the determinants of HIV infection are performed at the individual level. The recent Demographic and Health Surveys which include results from HIV tests allow studying HIV infection at the level of the cohabiting couple. The paper exploits this feature of the data for Burkina Faso, Cameroon, Ghana, Kenya, and Tanzania. The analysis yields two surprising findings about the dynamics of the HIV/AIDS epidemic which have important implications for policy. First, at least two-thirds of the infected couples are discordant couples, that is, couples where only one of the two partners is infected. This implies that there is scope for prevention efforts among couples. Second, between 30 and 40 percent of the infected couples are couples where the female partner only is infected. This is at odds with levels of self-reported marital infidelity by females and with the common perception that unfaithful males are the main link between high risk groups and the general population. This study investigates and confirms the robustness of these findings. For example, even among couples where the woman has been in only one union for 10 years or more, the fraction of couples where only the female partner is infected remains high. These results suggest that extramarital sexual activity among cohabiting women, whatever its causes, is a substantial source of vulnerability to HIV that should be, as much as male infidelity, targeted by prevention efforts. Moreover, this paper uncovers several inconsistencies between the sexual behaviors reported by male and female partners, suggesting that as much as possible, prevention policies should rely on evidence including objectively measured HIV status. -

The Determinants of HIV Infection and Related Sexual Behaviors : Evidence from Lesotho
(World Bank, Washington, DC, 2007-12)This paper analyzes the socioeconomic determinants of HIV infection and related sexual behaviors using the 2004 Lesotho Demographic and Health Survey. The authors find that in Lesotho education appears to have a protective effect: it is negatively associated with HIV infection (although not always significantly) and it strongly predicts preventive behaviors. The findings also show that married women who have extra-marital relationships are less likely to use a condom than non-married women. This is an important source of vulnerability that should be addressed in prevention efforts. The paper also analyzes HIV infection at the level of the couple. It shows that in 41 percent of the infected couples, only one of the two partners is HIV infected. Therefore, there are still opportunities for prevention inside the couple. -

Information is Power : Experimental Evidence on the Long-Run Impact of Community Based Monitoring
(World Bank Group, Washington, DC, 2014-08)This paper presents the results of two field experiments on local accountability in primary health care in Uganda. Efforts to stimulate beneficiary control, coupled with the provision of report cards on staff performance, resulted in significant improvements in health care delivery and health outcomes in both the short and the longer run. Efforts to stimulate beneficiary control without providing information on performance had no impact on quality of care or health outcomes. The paper shows that informed users are more likely to identify and challenge (mis)behavior by providers and as a result turn their focus to issues that they can manage locally. -

Rewarding Safer Sex : Conditional Cash Transfers for HIV/STI Prevention
(World Bank Group, Washington, DC, 2014-11)Incentive-based policies have been shown to be powerful in many areas of behavior, but have rarely been tested in the sexual domain. The Rewarding Sexually Transmitted Infection Prevention and Control in Tanzania (RESPECT) study is a randomized controlled trial testing the hypothesis that a system of rapid feedback and positive reinforcement that uses cash as the primary incentive can be used to reduce risky sexual activity among young people, male and female, who are at high risk of HIV infection. The study enrolled 2,399 participants in 10 villages in rural southwest Tanzania. The intervention arm received conditional cash transfers that depended on negative results of periodic screenings for sexually transmitted infections, an objectively measured marker for risky sexual behavior. The intervention arm was further divided into two subgroups, one receiving a high value payment of up to $60 over the course of the study ($20 payments every four months) and the other receiving a lower value payment of up to $30 ($10 payments every four months). At the end of the one year of intervention, the results showed a significant reduction in sexually transmitted infections in the group that was eligible for the $20 payments every four months, but no such reduction was found for the group receiving the $10 payments. The effects were stronger among the lower socioeconomic and higher risks groups. The results of a post-intervention follow-up survey conducted one year after discontinuing the intervention indicate a sustained effect among males, but not among females. -

Evidence from a Randomized Evaluation of the Household Welfare Impacts of Conditional and Unconditional Cash Transfers Given to Mothers or Fathers
(World Bank, Washington, DC, 2016-06)This study conducted a randomized control trial in rural Burkina Faso to estimate the impact of alternative cash transfer delivery mechanisms on education, health, and household welfare outcomes. The two-year pilot program randomly distributed cash transfers that were either conditional or unconditional and were given to either mothers or fathers. Conditionality was linked to older children enrolling in school and attending regularly and younger children receiving preventive health check-ups. Compared with the control group, cash transfers improve children's education and health and household socioeconomic conditions. For school enrollment and most child health outcomes, conditional cash transfers outperform unconditional cash transfers. Giving cash to mothers does not lead to significantly better child health or education outcomes, and there is evidence that money given to fathers improves young children's health, particularly during years of poor rainfall. Cash transfers to fathers also yield relatively more household investment in livestock, cash crops, and improved housing. -

The Demographic and Socio-economic Distribution of Excess Mortality during the 1994 Genocide in Rwanda
( 2009-03-01)There is an extensive literature on violent conflicts such as the 1994 Rwandan genocide, but few papers examine the profiles of victims and perpetrators, or more broadly the micro-level dynamics of widespread violence. This paper studies the demographic consequences of the Rwandan genocide and how the excess mortality due to the conflict was distributed in the population. Data collected by the 2000 Demographic and Health Survey indicate that although there were more deaths across the entire population, adult males were the most likely to die. Using the characteristics of the survey respondent as a proxy for the socio-economic status of the family dead, the results also show that individuals with an urban or more educated background were more likely to die. Over and above the human tragedies, a long-term cost of the genocide is the country's loss of productive skills. -

Stimulating Demand for AIDS Prevention : Lessons from the RESPECT Trial
( 2012-02-01)HIV-prevention strategies have yielded only limited success so far in slowing down the AIDS epidemic. This paper examines novel intervention strategies that use incentives to discourage risky sexual behaviors. Widely-adopted conditional cash transfer programs that offer payments conditioning on easily monitored behaviors, such as well-child health care visits, have shown positive impact on health outcomes. Similarly, contingency management approaches have successfully used outcome-based rewards to encourage behaviors that are not easily monitored, such as stopping drug abuse. These strategies have not been used in the sexual domain, so this paper assesses how incentives can be used to reduce risky sexual behavior. After discussing theoretical pathways, it discusses the use of sexual-behavior incentives in the Tanzanian RESPECT trial. There, participants who tested negative for sexually transmitted infections are eligible for outcome-based cash rewards. The trial was well-received in the communities, with high enrollment rates and more than 90 percent of participants viewing the incentives favorably. After one year, 57 percent of enrollees in the "low-value" reward arm stated that the cash rewards "very much" motivated sexual behavioral change, rising to 79 percent in the "high-value" reward arm. Despite its controversial nature, the authors argue for further testing of such incentive-based approaches to encouraging reductions in risky sexual behavior. -

Sexual Behavior Change Intentions and Actions in the Context of a Randomized Trial of a Conditional Cash Transfer for HIV Prevention in Tanzania
( 2012-03-01)Information, education, communication and interventions based on behavioral-change communication have had success in increasing the awareness of HIV. But these strategies alone have been less successful in changing risky sexual behavior. This paper addresses this issue by exploring the link between action and the intention to change behaviors. In Africa, uncertainty in the lives of those at risk for HIV may affect how intentions are formed. Characterize this uncertainty by understanding the reasons for discrepancies between intentions and actions may help improve the design of HIV-prevention interventions. Based on an incentives-based HIV prevention trial in Tanzania, the longitudinal dataset in this paper allows the exploration of intended strategies for changing sexual behaviors and their results. The authors find that gender, intervention groups and new positive diagnoses of sexually transmitted infections can significantly predict the link between intent and action. The paper examines potential mediators of these relationships.
