Sexual health problems cause negative externalities from contagious diseases and public expenditure burdens from teenage pregnancies. In a randomized evaluation, we find that an online sexual health education course in Colombia leads to significant impacts on knowledge and attitudes but no impact on selfreported behavior, on average; although fewer STIs are reported for baseline sexually active females. To go beyond self-reported measures, we provide condom vouchers six months after the course to both treatment and control groups and estimate a 9 percentage point treatment effect (52% increase) on the likelihood of redemption. Using knowledge of friendship networks, we document a strong social reinforcement effect: the impacts of the course intensify when a larger fraction of a student’s friends is also treated. In particular, when full sets of friends are treated we find significant reductions in sexually active, frequency of sex, and number of partners. Throughout the analysis we fail to find evidence of cross-classroom spillovers.

In 2013 IPA celebrated ten years of producing high-quality evidence about what works, and what does not work, to improve the lives of the poor. It was a year of celebration for our accomplishments. More so, it was a time to prepare our organization for the next phase as we continue to pursue our vision of a world with More Evidence and Less Poverty.

Does providing information about a product influence the impact of price subsidies on purchases? This question is particularly relevant for health products in developing countries where both informational campaigns and price subsidies are common policy instruments. We conduct a field experiment in Zambia and find that providing information about a new version of a product significantly increases the impact of price subsidies on take-up. Taken alone, the information manipulation has no significant impact on demand while the price subsidy substantially increases demand. However, the evaluation of either intervention in isolation fails to capture the significant complementarity between the two.

There is growing interest in using messaging to drive prosocial behaviors, which contribute to investment in public goods. The authors worked with a leading nongovernmental organization in Peru to randomize nine different prorecycling messages that were crafted on the basis of best practices, prior evidence, and theories of behavioral change. Different variants emphasized information on environmental or social benefits, social comparisons, social sanctions, authority, and reminders. None of the messages had significant effects on recycling behavior. However, reducing the cost of ongoing participation by providing a recycling bin significantly increased recycling among enrolled households.

This study estimates long-run impacts of a child health investment, exploiting community-wide experimental variation in school-based deworming. The program increased education among women and labor supply among men, with accompanying shifts in labor market specialization. Ten years after deworming treatment, women who were eligible as girls are 25% more likely to have attended secondary school, halving the gender gap. They reallocate time from traditional agriculture into cash crops and entrepreneurship. Men who were eligible as boys stay enrolled for more years of primary school, work 17% more hours each week, spend more time in entrepreneurship, are more likely to hold manufacturing jobs, and miss one fewer meal per week. We estimate an annualized financial internal rate of return of at least 32.2%.

We evaluate the impact of a health information intervention implemented through mobile phones, using a clustered randomized control trial augmented by qualitative interviews. The intervention aimed to improve sexual health knowledge and shift individuals towards safer sexual behavior by providing reliable information about sexual health. The novel technology designed by Google and Grameen Technology Center provided automated searches of an advice database on topics requested by users via SMS. It was offered by MTN Uganda at no cost to users. Quantitative survey results allow us to reject the hypothesis that improving access to information would increase knowledge and shift behavior to less risky sexual activities. In fact, we find that the service led to an increase in promiscuity, and no shift in perception of norms. Qualitative focus groups discussions support the findings of the quantitative survey results. We conclude by discussing a potential mechanism explaining the counterintuitive findings

An individual who takes an HIV test can be informed about their own status and risk. Similarly, when friends, family or neighbors learn of a person's HIV status, they may update their beliefs about HIV infection among people they know. Using an experiment conducted in rural Malawi which randomly assigned incentives to learn HIV results, we find that as people in the community learn their HIV results, individuals revise their beliefs downward about deaths attributable to HIV/AIDS. We find corresponding behavioral responses with a significant decrease in condom use and no significant increase in multiple partnerships among those who are HIV-negative.

Despite the fact that national health insurance has been available in Ghana since 2003, the coverage is far from universal, especially in rural areas. This study evaluates a consumer education intervention for microfinance clients by Freedom from Hunger and Sinapi Aba Trust designed to increase awareness, knowledge and eventually take-up rates of the National Health Insurance Scheme (NHIS).

Using data from a field experiment in Kenya, we document that providing individuals with simple informal savings technologies can substantially increase investment in preventative health and reduce vulnerability to health shocks. Simply providing a safe place to keep money was sufficient to increase health savings by 66 percent. Adding an earmarking feature was only helpful when funds were put toward emergencies, or for individuals that are frequently taxed by friends and relatives. Group-based savings and credit schemes had very large effects.

This paper examines whether an intra-household externality prevents adoption of a technology with substantial implications for population health and the environment: improved cookstoves. Motivated by a model of intra-household decision-making, the experiment markets stoves to husbands or wives in turn at randomly varying prices. We find that women – who bear disproportionate cooking costs – have stronger preference for healthier stoves, but lack the authority to make purchases. Our findings suggest that if women cannot make independent choices about household resource use, public policy may not be able to exploit gender differences in preferences to promote technology adoption absent broader social change.
