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. -

Coping with Risk : The Effects of Shocks on Reproductive Health and Transactional Sex in Rural Tanzania
(World Bank, Washington, DC, 2014-01)Transactional sex is believed to be an important risk-coping mechanism for women in Sub-Saharan Africa and a leading contributor to the HIV/AIDS epidemic. This paper uses data from a panel of women in rural Tanzania whose primary occupation is agriculture. The analysis finds that following a negative shock (such as food insecurity), unmarried women are about three times more likely to have been paid for sex. Regardless of marital status, after a shock women have more unprotected sex and are 36 percent more likely to have a sexually transmitted infection. These empirical findings support the claims that transactional sex is not confined to commercial sex workers and that frequently experienced shocks, such as food insecurity, may lead women to engage in transactional sex as a risk-coping behavior. -

Armed Conflict and Schooling : Evidence from the 1994 Rwandan Genocide
(World Bank, Washington, DC, 2008-04)Civil war, and genocide in particular, are among the most destructive of social phenomena, especially for children of school-going age. In Rwanda school enrollment trends suggest that the school system recovered quickly after 1994, but these numbers do not tell the full story. Two cross-sectional household surveys collected before and after the genocide are used to compare children in the same age group who were and were not exposed to the genocide - and their educational outcomes are substantially different. Children exposed to the genocide experienced a drop in educational achievement of almost one-half year of completed schooling, and are 15 percentage points less likely to complete third or fourth grade. Sustained effort is needed to reinforce educational institutions and offer a "second chance" to those youth most affected by the conflict. -

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. -

Antiretroviral Therapy Awareness and Risky Sexual Behaviors : Evidence from Mozambique
( 2010-11-01)This paper studies the effect of increased access to antiretroviral therapy on risky sexual behavior, using data collected in Mozambique in 2007 and 2008. The survey sampled both households of randomly selected HIV positive individuals and households from the general population. Controlling for unobserved individual characteristics, the findings support the hypothesis of disinhibition behaviors, whereby risky sexual behaviors increase in response to the perceived changes in risk associated with increased access to antiretroviral therapy. Furthermore, men and women respond differently to the perceived changes in risk. In particular, risky behaviors increase for men who believe, wrongly, that AIDS can be cured, while risky behaviors increase for women who believe, correctly, that antiretroviral therapy can treat AIDS but cannot cure it. The findings suggest that scaling up access to antiretroviral therapy without prevention programs may not be optimal if the objective is to contain the disease, since people would adjust their sexual behavior in response to the perceived changes in risk. Therefore, prevention programs need to include educational messages about antiretroviral therapy, and address the changing beliefs about HIV in the era of increasing antiretroviral therapy availability. -

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.
