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.

Cash Transfers and Child Schooling : Evidence from a Randomized Evaluation of the Role of Conditionality
(World Bank, Washington, DC, 2013-01)The authors conduct a randomized experiment in rural Burkina Faso to estimate the impact of alternative cash transfer delivery mechanisms on education. The two-year pilot program randomly distributed cash transfers that were either conditional or unconditional. Families under the conditional schemes were required to have their children ages 7-15 enrolled in school and attending classes regularly. There were no such requirements under the unconditional programs. The results indicate that unconditional and conditional cash transfer programs have a similar impact increasing the enrollment of children who are traditionally favored by parents for school participation, including boys, older children, and higher ability children. However, the conditional transfers are significantly more effective than the unconditional transfers in improving the enrollment of "marginal children" who are initially less likely to go to school, such as girls, younger children, and lower ability children. Thus, conditionality plays a critical role in benefiting children who are less likely to receive investments from their parents. -

Who Gets AIDS and How? The Determinants of HIV Infection and Sexual Behaviors in Burkina Faso, Cameroon, Ghana, Kenya and Tanzania
(World Bank, Washington, DC, 2006-02)This paper analyzes the determinants of HIV infection and associated sexual behaviors using data from the first five Demographic and Health Surveys to include HIV testing for a representative sample of the adult population. Emerging from a wealth of country relevant results, four important findings can be generalized. First, married women who engage in extra-marital sex are less likely to use condoms than single women when doing so. Second, having been in successive marriages is a significant risk-factor, as evidenced by the results on HIV infection and on sexual behaviors. Contrary to prima facie evidence, education is not associated positively with HIV status. But schooling is one of the most consistent predictors of behavior and knowledge: education predicts protective behaviors like condom use, use of counseling and testing, discussion among spouses and knowledge, but it also predicts a higher level of infidelity and a lower level of abstinence. Finally, male circumcision and female genital mutilation are often associated with sexual behaviors, practices, and knowledge related to AIDS. This might explain why in the analysis in the five countries there is no significant negative association between male circumcision and HIV status, despite recent evidence from a randomized control trial that male circumcision has a protective effect. -

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. -

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 use of video vignettes to measure health worker knowledge: Evidence from Burkina Faso
(Elsevier, 2018-09)The quality of care is a crucial determinant of good health outcomes, but is difficult to measure. Survey vignettes are a standard approach to measuring medical knowledge among health care providers. Given that written vignettes or knowledge tests may be too removed from clinical practice, particularly where “learning by doing” may be an important form of training, we developed a new type of provider vignette. It uses videos presenting a patient visiting the clinic with maternal/early childhood symptoms. We tested these video vignettes with current and future (students) health professionals in Burkina Faso. Participants indicated that the cases used were interesting, understandable and common. Their performance was consistent with expectations. Participants with greater training (medical doctors vs. nurses and midwives) and experience (health professionals vs. students) performed better. The video vignettes can easily be embedded in computers, tablets and smart phones; they are a convenient tool to measure provider knowledge; and they are cost-effective instruction and testing tools. -

Child Ability and Household Human Capital Investment Decisions in Burkina Faso
( 2010-07-01)Using data they collected in rural Burkina Faso, the authors examine how children's cognitive abilities influence resource constrained households' decisions to invest in their education. This paper uses a direct measure of child ability for all primary school-aged children, regardless of current school enrollment. The analysis explicitly incorporates direct measures of the ability of each child s siblings (both absolute and relative measures) to show how sibling rivalry exerts an impact on the parents decision of whether and how much to invest in their child s education. The findings indicate that children with one standard deviation higher own ability are 16 percent more likely to be currently enrolled, while having a higher ability sibling lowers current enrollment by 16 percent and having two higher ability siblings lowers enrollment by 30 percent. The results are robust to addressing the potential reverse causality of schooling influencing child ability measures and using alternative cognitive tests to measure ability. -

Educational and Health Impacts of Two School Feeding Schemes : Evidence from a Randomized Trial in Rural Burkina Faso
( 2009-06-01)This paper uses a prospective randomized trial to assess the impact of two school feeding schemes on health and education outcomes for children from low-income households in northern rural Burkina Faso. The two school feeding programs under consideration are, on the one hand, school meals where students are provided with lunch each school day, and, on the other hand, take-home rations that provide girls with 10 kg of cereal flour each month, conditional on 90 percent attendance rate. After running for one academic year, both programs increased girls enrollment by 5 to 6 percentage points. While there was no observable significant impact on raw scores in mathematics, the time-adjusted scores in mathematics improved slightly for girls. The interventions caused absenteeism to increase in households that were low in child labor supply while absenteeism decreased for households that had a relatively large child labor supply, consistent with the labor constraints. Finally, for younger siblings of beneficiaries, aged between 12 and 60 months, take-home rations have increased weight-for-age by .38 standard deviations and weight-for-height by .33 standard deviations. In contrast, school meals did not have any significant impact on the nutrition of younger children. -

Encouraging Service Delivery to the Poor: Does Money Talk When Health Workers Are Pro-Poor?
(World Bank, Washington, DC, 2018-12)Do service providers respond to pecuniary incentives to serve the poor? Service delivery to the poor is complicated by the extra effort required to deliver services to them and the intrinsic incentives of service providers to exert this effort. Incentive schemes typically fail to account for these complications. A lab-in-the-field experiment with nearly 400 health workers in rural Burkina Faso provides strong evidence that the interaction of effort costs, ability, and intrinsic and extrinsic incentives significantly influences service delivery to the poor. Health workers reviewed video vignettes of medical cases involving poor and nonpoor patients under a variety of bonus schemes. Bonuses to serve the poor have less impact on effort than bonuses to serve the nonpoor; health workers who receive equal bonuses to serve poor and nonpoor patients see fewer poor patients than workers who receive only a flat salary; and bonuses operate largely through their influence on the behavior of pro-poor workers. The paper also presents novel evidence on the selection effects of contract type: pro-poor workers prefer the flat salary contract to the variable salary contract. -

Looking into the performance-based financing black box: Evidence from an impact evaluation in the health sector in Cameroon
(Oxford University Press, 2021-07)Performance-based financing (PBF) is a complex health systems intervention aimed at improving the coverage and quality of care. Several studies have shown a positive impact of PBF on health service coverage, often coupled with improvements in quality, but relatively little is known about the mechanisms driving those results. This article presents results of a randomized impact evaluation in Cameroon designed to isolate the role of specific components of the PBF approach with four study groups: (i) PBF with explicit financial incentives linked to results, (ii) direct financing with additional resources available for health providers not linked to performance, (iii) enhanced supervision and monitoring without additional resources and (iv) a control group. Overall, results indicate that, when compared with the pure control group, PBF in Cameroon led to significant increases in utilization for several services (child and maternal vaccinations, use of modern family planning), but not for others like antenatal care visits and facility-based deliveries. In terms of quality, PBF increased the availability of inputs and equipment, qualified health workers, led to a reduction in formal and informal user fees but did not affect the content of care. However, for many positively impacted outcomes, the differences between the PBF group and the group receiving additional financing not linked to performance are not significant, suggesting that additional funding rather than the explicit incentives might be driving improvements. In contrast, the intervention group offering enhanced supervision, coaching and monitoring without additional funding did not experience significant impacts compared to the control group. -

Looking into the Performance-Based Financing Black Box: Evidence from an Impact Evaluation in the Health Sector in Cameroon
(World Bank, Washington, DC, 2017-08)Performance-based financing is a complex health system intervention aimed at improving coverage and quality of care. This paper presents the results of an impact evaluation in Cameroon that seeks to isolate the role of specific components of the performance-based financing approach on outcomes of interest, such as explicit financial incentives linked to results, additional resources available at the point of service delivery (not linked to performance), and enhanced supervision, coaching, and monitoring. Four evaluation groups were established to measure the effects of each component that was studied. In general, the results indicate that performance-based financing in Cameroon is an efficient mechanism to channel payments and funding to the provider level, leading to significant increases in utilization in the performance-based financing arm for several services (child and maternal vaccinations and use of modern family planning), but not for others, such as antenatal care visits and facility-based deliveries. However, for many of those outcomes, the differences between the performance-based financing group and the additional financing group are not significant. In terms of quality, performance-based financing was found to have a significant impact on the availability of essential inputs and equipment, qualified health workers, reduction in formal and informal user fees, and increased satisfaction among patients and providers. However, there was a clear effect of additional financing, irrespective of whether it was linked to incentives, in combination with reinforced supervision through performance-based financing. This result suggests that enhanced supervision and monitoring on their own are not sufficient to improve maternal and child health outcomes.
