1. Psychological trainings increase chlorination rates
Haushofer, John, and Orkin 2018: (RCT in Kenya) “One group received a two-session executive function intervention that aimed to improve planning and execution of plans; a second received a two-session time preference intervention aimed at reducing present bias and impatience. A third group receives only information about the benefits of chlorination, and a pure control group received no intervention.” Executive function and time preference trainings led to stat sig increases in chlorination and stat sig decreases in diarrhea rates.
2. Conditional cash transfers reduce suicides!
Christian, Hensel, and Roth 2018: (RCT in Indonesia) This paper is so cool! One mechanism is by mitigating the negative impact of bad agricultural shocks and decreasing depression. “We examine how income shocks affect the suicide rate in Indonesia. We use both a randomized conditional cash transfer experiment, and a difference-in-differences approach exploiting the cash transfer’s nation-wide roll-out. We find that the cash transfer reduced yearly suicides by 0.36 per 100,000 people, corresponding to an 18 percent decrease. Agricultural productivity shocks also causally affect suicide rates. Moreover, the cash transfer program reduces the causal impact of the agricultural productivity shocks, suggesting an important role for policy interventions. Finally, we provide evidence for a psychological mechanism by showing that agricultural productivity shocks affect depression.”
3. Women police stations increased reporting of crimes against women
Amaral, Bhalotra, and Prakash 2018: (in India) “Using an identification strategy that exploits the staggered implementation of women police stations across cities and nationally representative data on various measures of crime and deterrence, we find that the opening of police stations increased reported crime against women by 22 percent. This is due to increases in reports of female kidnappings and domestic violence. In contrast, reports of gender specific mortality, self-reported intimate-partner violence and other non-gender specific crimes remain unchanged.”
