Labor movements can improve workers’ lives but face great difficulty in getting workers to agree on common goals and take collective actions. In garment factory workers’ group discussions on minimum wage policies in Myanmar, researchers randomly included union leaders to study whether the presence of union leaders affected workers’ preferences and behavior. Union leaders’ presence at group discussions increased the degree of agreement between the workers’ and unions’ preferred wage levels, and made it more likely that workers participated in a subsequent group activity, suggesting that union leaders both helped form workers’ consensus and motivated them to take collective actions. Researchers found evidence that union leaders’ influence on these outcomes came from the leaders’ ability and skills rather than formal title or social ties.

Working with local government leaders and agricultural extension agents, the researcher is conducting a randomized evaluation to test the impact of promoting a mechanization technology. Uniquely, the researcher will closely track how employment shifts for women who formerly did the mechanized work.

Re searchers used a randomized evaluation to measure the impact of providing mobile calling credits to low-income adults on well-being outcomes in Ghana. Overall, the mobile credit intervention increased the ability for individuals to meet unexpected communication needs, particularly when delivered in installments, leading to meaningful improvements in mental health and modest decreases to domestic violence.

Researchers randomly provided more or less cash to garment-making firm owners in Ghana before a bargaining game to evaluate the impact of endowment on the negotiated sale price of a good. Owners of garment-making microenterprises with lower household liquidity agreed to lower sale prices during the bargaining process, suggesting that the prior wealth of microentrepreneurs who participate in bargaining may impact how much they are able to earn.

The researcher evaluated the impact of a sexual harassment training on the incidence of sexual harassment, opposite sex relationships, and attitudes and beliefs towards sexual harassment in India. Overall, the training reduced extreme forms of sexual harassment in the short run and intermediate forms of harassment in the long run, likely by changing men’s beliefs about others' attitudes to sexual harassment. The training also reduced opposite sex romantic relationships between classmates.

Across six randomized evaluations, researchers studied the impact of low-cost, low-touch informational interventions, or “nudges,” on take-up of the federal and state Earned Income Tax Credit (EITC) in California. None of the interventions had an impact on EITC take-up, suggesting that information alone may be insufficient to overcome administrative burdens.

In Ghana, researchers evaluated the impact of providing vendors and consumers with information on official mobile money charges and options for recourse for consumers to report being overcharged. The program led to a decrease in misconduct, which in turn facilitated an increase in market activity, firm sales revenue, and consumer welfare.

Researchers sought to determine whether providing information on the EITC could increase the amount individuals received by randomizing the information professional tax preparers supplied. They found that providing more information did not increase EITC transfers or annual earnings overall.

Researchers partnered with the Bavarian State Opera House in Germany to evaluate the impact of a variety of communications strategies on the frequency of donations. They found that including a pre-filled bank transfer form in the letter substantially increased the response rate, perhaps because this lowered the effort required to make a donation. Providing non-responsive donors with a reminder to donate also proved relatively effective, but featuring slogans prominently on envelopes had no effect.

This evaluation studies the effects of flexible repayment schedules on borrowers’ investment level, consumption, and loan default in the dairy industry in India.

In Ethiopia, researchers tested whether linking microcredit and family planning services could increase contraceptive use more than either program in isolation. Neither the linked program nor the isolated programs had any detectable impact on contraceptive awareness, use, or intention to use.

In India, researchers randomly assigned microfinance clients to monthly or weekly meeting schedules to test whether more frequent meetings could build social capital. They found that weekly meetings lead to higher levels of social interaction that continued beyond the initial loan cycle, which reduced default on subsequent loans but did not lead to measurable gains in female empowerment.

Researchers randomized the suggested contribution in a fundraising appeal sent to patrons of the Bavaria State Opera (Germany). They found that the suggestions increased the average donation while decreasing the participation rate, resulting in no significant change in the average return per mailing.

Researchers conducted a randomized evaluation in Ethiopia, Tanzania, and Zambia to measure whether generating social connections between manufacturing firm managers could lead to the diffusion and adoption of best business practices. These social interactions led to the spread of best practices related to business formalization, but did not increase the implementation of other practices that may boost business productivity.

Researchers in northern Ghana conducted a randomized evaluation to assess the underlying reason for underinvestment by examining the relative effectiveness of cash grants and insurance grants in improving crop yields. Results suggest that uninsured risk, rather than a lack of capital, was the primary constraint on investment. Researchers found that farmers who received free insurance spent more on fertilizer and hired labor, and they also cultivated more land than those who received cash grants.
