The Impact of Group-Based Grain Storage Schemes on Farmers Savings and Incomes in Kenya
Researchers worked with existing savings clubs in Kenya to study the effect of two interventions on savings: the provision of communal crop storage devices and the provision of savings accounts earmarked for farm purchases. Researchers find that the products were popular: about 56% of farmers took up the products. Respondents in the maize storage intervention were 23 percentage points more likely to store maize (on a base of 69%), 37 percentage points more likely to sell maize (on a base of 36%) and (conditional on selling) sold later and at higher prices.

Discrimination in Hiring and Anonymous CVs in France (CV Anonymes)
In collaboration with the French employment agency Pôle Emploi, researchers evaluated whether interview and hiring rates of minority candidates changed when employers collect anonymous resumes. Making resumes anonymous did not affect the average number of interviews and job offers volunteer firms made, the length of the hiring process, or the use of other recruitment channels, but it reduced the likelihood that firms interview and hire minority candidates.

Researchers tested the effects of providing low-income students in urban Chile with information about financial aid for higher education on their educational attainment and their likelihood of progressing to higher education. A video informing students about financing higher education increased enrollment in college preparatory schools and increased school attendance, particularly among medium- and high-performing students, but had no effect on grades.

Text message reminders decreased failure to appear in court in New York City
Researchers partnered with policymakers in New York City to evaluate the impacts of a redesigned court summons form and text message reminders on failure to appear (FTA) in court.
