Abstract
Female Sex Workers are a core population in the HIV epidemic, and interventions such as conditional cash transfers (CCTs), effective in other health domains, are a promising new approach to reduce the spread of HIV. Here we investigate how a population of Tanzanian female sex workers, though constrained in many ways, experience and use their power in the context of a CCT intervention that incentivizes safe sex. We analyzed 20 qualitative in-depth interviews with female sex workers enrolled in a randomized-controlled CCT program, the RESPECT II pilot, and found that while such women have limited choices, they do have substantial power over their work logistics that they leveraged to meet the conditions of the CCT and receive the cash award. It was through these decisions over work logistics, such as reducing the number of workdays and clients, that the CCT intervention had its greatest impact on modifying female sex workers’ behavior.

Publication 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.Publication Incentivising Safe Sex : A Randomised Trial of Conditional Cash Transfers for HIV and Sexually Transmitted Infection Prevention in Rural Tanzania(2012-02-08)Objective The authors evaluated the use of conditional cash transfers as an HIV and sexually transmitted infection prevention strategy to incentivise safe sex. Design An unblinded, individually randomised and controlled trial. Setting 10 villages within the Kilombero/Ulanga districts of the Ifakara Health and Demographic Surveillance System in rural south-west Tanzania. Participants The authors enrolled 2399 participants, aged 18–30 years, including adult spouses. Interventions Participants were randomly assigned to either a control arm (n=1124) or one of two intervention arms: low-value conditional cash transfer (eligible for $10 per testing round, n=660) and high-value conditional cash transfer (eligible for $20 per testing round, n=615). The authors tested participants every 4 months over a 12-month period for the presence of common sexually transmitted infections. In the intervention arms, conditional cash transfer payments were tied to negative sexually transmitted infection test results. Anyone testing positive for a sexually transmitted infection was offered free treatment, and all received counselling. Main outcome measures The primary study end point was combined prevalence of the four sexually transmitted infections, which were tested and reported to subjects every 4 months: Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Mycoplasma genitalium. The authors also tested for HIV, herpes simplex virus 2 and syphilis at baseline and month 12. Results At the end of the 12-month period, for the combined prevalence of any of the four sexually transmitted infections, which were tested and reported every 4 months (C trachomatis, N gonorrhoeae, T vaginalis and M genitalium), unadjusted RR for the high-value conditional cash transfer arm compared to controls was 0.80 (95% CI 0.54 to 1.06) and the adjusted RR was 0.73 (95% CI 0.47 to 0.99). Unadjusted RR for the high-value conditional cash transfer arm compared to the low-value conditional cash transfer arm was 0.76 (95% CI 0.49 to 1.03) and the adjusted RR was 0.69 (95% CI 0.45 to 0.92). No harm was reported. Conclusions Conditional cash transfers used to incentivise safer sexual practices are a potentially promising new tool in HIV and sexually transmitted infections prevention. Additional larger study would be useful to clarify the effect size, to calibrate the size of the incentive and to determine whether the intervention can be delivered cost effectively.

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.Publication Potential Applications of Conditional Cash Transfers for Prevention of Sexually Transmitted Infections and HIV in Sub-Saharan Africa(World Bank, Washington, DC, 2008-07)A growing number of developing countries have introduced conditional cash transfer programs that provide money to poor families with certain contingencies attached - such as requiring school attendance or regular immunization and health check-ups. As the popularity of conditional cash transfer programs has grown, experimentation with potential applications in other areas of health, such as sexual and reproductive health, and HIV prevention, in particular, has also increased. Evaluations of conditional cash transfer programs have focused almost exclusively on uptake of health and educational services, which make relatively low demands of participants compared with more complex interventions, which require the cessation of risky behaviors, such as smoking, obesity, and substance abuse. The literature on contingency management - based on the principle that behavioral change occurs when appropriate behaviors are reinforced and rewarded - provides a richer picture of the complexity of the use of conditionality to encourage healthy behavioral change. This paper examines developing countries' experiences with conditional cash transfer programs and the results of trials in clinical settings on the efficacy of contingency management, and addresses their relevance for designing conditional cash transfer programs to address risky sexual behavior and promote the prevention of sexually transmitted infections and HIV in Sub-Saharan Africa.Publication Effect of a Lottery Intervention on Gender-Based Violence among Female Sex Workers in Dar es Salaam, Tanzania(World Bank, 2023-10-02)Financial incentives are a promising approach for HIV prevention. Some studies have shown that financial incentive interventions aimed to promote positive health and social behaviors have mixed or harmful effects on gender-based violence, and little is known about their effects among higher risk groups such as female sex workers. To address this gap, this study investigated the relationship between a lottery-based incentive and gender-based violence among female sex workers in Dar es Salaam, Tanzania. Data were analyzed from the RESPECT II trial, which enrolled 2,206 female sex workers in Dar es Salaam, Tanzania, to evaluate the effect of a lottery-based incentive on HIV and sexually transmitted infections. Participants were randomized in a one-to-one ratio to: (1) the basic test group (control), which provided baseline testing and counseling for HIV and sexually transmitted infections and bi-weekly text messages on safe sex practices; or (2) the lottery group, which included the basic test group intervention plus entry into a weekly random lottery for an award of 100,000 Tanzanian shillings conditional on negative tests for sexually transmitted infections (syphilis and trichomonas vaginalis). An intent-to-treat analysis was conducted to estimate differences in physical and sexual gender-based violence (overall), and intimate partner violence and non-partner violence between treatment arms at endline, with estimates expressed as unadjusted prevalence differences with 95 percent confidence intervals. Adjusted estimates controlled for baseline reports of violence. Multiple imputation and inverse-probability of treatment weighting were used to account for missing data. Causal, population-level impacts were estimated using g-computation. Gender-based violence, intimate partner violence, and non-partner violence declined in both treatment arms over the study period among the sample of 1,117 female sex workers retained at endline. The lottery group had a lower prevalence of gender-based violence overall, intimate partner violence, and non-partner violence compared to control at endline; however, the differences were not statistically significant. The results indicate that the lottery intervention had no effect on violence outcomes among endline participants in the RESPECT II trial. These results suggest that this economic approach does not pose additional risks of violence in the context of sex work; however, they must be interpreted with caution due to high attrition in the study sample. Additional research is warranted to examine how this incentive mechanism impacts violence for female sex workers.

Publication The Inverting Pyramid : Pension Systems Facing Demographic Challenges in Europe and Central Asia(Washington, DC: World Bank, 2014-02-12)Pension systems in Europe and Central Asia are facing unprecedented demographic change. While many of the countries in the region have undertaken reforms when the economy faces difficult times, these reforms are frequently reversed when the economy improves. The demographic challenges that the region faces require a sustained effort toward changing the pension system toward something which provides adequate and sustainable benefits. The book documents the increased generosity of pension systems in Europe from their initial inception, noting that the current expectations of the public are based on the most recent round of generosity. The book seeks to show a nontechnical audience that such generosity is neither based on customary practice nor affordable in the future. The increased generosity in the past was only possible because the demographic pyramid was expanding, but as it inverts with fewer young people and more elderly, that generosity will no longer be affordable. Returning to the pension system of the 1970’s will go a long way toward providing adequate and sustainable benefits in the future. Moving to a more sustainable system will require reforms to labor markets, improvements in savings mechanisms, and may require additional public resources. The extent to which a country can undertake reforms in labor markets, savings, and public finances can influence the extent to which its pension system will have to change, with different solutions possible for different countries. But in all cases, the changes that need to be made have to be widely discussed and publicly accepted to prevent reversals. The book hopes to stimulate widespread public discussion of the issue to help countries make sustainable choices with gradual implementation, before they face such daunting challenges that they have to undertake sudden, harsh measures.Publication Reforming Payments and Securities Settlement Systems in Latin America and the Caribbean(Washington, DC : World Bank, 2007)The payments and securities settlement system is the infrastructure (comprising institutions, instruments, rules, procedures, standards, and technical means) established to effect the transfer of monetary value between parties discharging mutual obligations. A securities clearance and settlement system can be considered as part of the overall payment mechanisms of a country, in that it satisfies the main features of this overall definition The purpose of this book is to (a) extract the main lessons and experiences of the Western Hemisphere Payments and Securities Clearance and Settlement Initiative - Western Hemisphere Payments and Securities Settlement Forum (WHI-WHF) regarding the implementation of various reforms; (b) describe status of and major trends in payments and securities settlement systems worldwide and their implications for the LAC region; (c) summarize the detailed assessment findings for each LAC country in the following fields: (1) legal and regulatory framework, (2) main characteristics of the inter-bank exchange and settlement circuits, (3) retail settlement systems, (4) the role of the government as a major participant in the payments system, (5) foreign exchange and cross-border settlement, (6) the operation of the inter-bank money market, (7) aspects related to securities settlement such as the legal framework, clearance and settlement processes, settlement risks, operational reliability, custody, depositories' organizational arrangements, cross-border links, and (8) the oversight role of the central bank, coordination with the regulatory and supervisory role over securities settlement, and cooperation with the private sector; and (d) propose practical observations regarding the implementation of payments and securities settlement system reforms in the LAC region.Publication Malawi Engaging the Private Sector in Education(World Bank, Washington, DC, 2017-06)This report presents an analysis of how effectively current policies in Malawi engage the private sector in primary and secondary education. The analysis draws on the engaging the private sector (EPS) framework, a product of the World Bank’s systems approach for better education results (SABER). SABER-EPS research in Malawi found that the net enrollment rate for primary education has increased significantly, to 89 percent, while secondary net enrollment rate remains low, at only 11 percent as of 2013 (the latest available data). At both the primary and secondary levels, quality, and equity are challenges. The private sector plays an increasingly significant role in education at both levels. Based on a review of existing policies, SABER-EPS offers the following recommendations for enhancing private sector engagement in the education sector in the country in order to meet the challenges of access, quality, and equity: (1) concentrate on improving the quality of learning outcomes by encouraging continuous improvement at the school level by means of school improvement planning and incentives; (2) empower parents by ensuring that they are given information on school quality that enables them to make informed choices and are not hindered by restrictive school selection criteria; and (3) create a regulatory environment that encourages greater supply of school places to help overcome constraints, particularly at the secondary level. The report provides an overview of SABER-EPS, followed by a description of the primary and secondary education system in Malawi with a focus on the private sector and government policies related to the private provision of education. The report then benchmarks Malawi’s policy environment utilizing the SABER-EPS Framework and offers policy options to enhance access and learning for all children in primary and secondary school.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Growth Spillover Effects and Regional Development Patterns : The Case of Chinese Provinces(World Bank, Washington, DC, 2005-06)The author discusses regional development patterns in China and examines effective ways of using development aid to attain regional balanced growth through optimizing growth spillover effects. Based on provincial panel data from 1978-99 she constructs an indicator "neighborhood performance" to measure the geographic spillover effects of aggregate growth from and to different provinces according to their relative richness and geographic position. Analysis of a Solow-type growth model suggests that positive spillover effects dominate negative shadow effects at the national level as well as the regional level, and some coastal provinces provide growth pull and growth push forces for their neighbors and serve as locomotives. The results show that the rapid takeoff of the coastal provinces has the largest spillover effects on the Chinese economy, but at the expense of a widening regional gap. A policy of encouraging the growth of the non-coastal regional hubs would have strong forward and backward linkages with the inland and western regions and thus reduce the regional development gap without sacrificing much aggregate growth. The author offers support for the policy of developing inland hubs, and argues that directing development aid to Hubei and Sichuan would optimize the growth spillover impacts on inland regions.
