Researchers evaluated the impact of a voluntary commitment savings program that allowed individuals to deposit a self-selected amount of their own money that would be forfeited if they did not quit smoking within six months. Results suggested that individuals who were offered the program were much more likely to quit smoking.

Researchers found that both individuals with higher moral standards and individuals who were the least naïve displayed lower default rates than other groups. They also found that survey-based social capital measures did not predict loan default for these individual loans, contrary to the results from a prior study of group loans. Additionally, researchers found that more general personality index measures were not good predictors of default.

Researchers partnered with CNS to investigate whether requiring clients to sign a non-binding agreement to save a predetermined amount of each remittance received could increase saving.

Researchers offered market vendors and bicycle taxi drivers in rural Kenya the opportunity to open a savings account at no cost. The formal savings accounts increased savings, productive investments, and expenditure levels among female micro-entrepreneurs, but not among males.

Researchers measured the impact of different interest rates loan take-up, amount, and repayment rates among female clients of Compartamos Banco in Mexico. Lower interest rates led to an increase in the number of loans issued, loan amounts, and new borrowers but did not increase profits in the short term.

Researchers in Zambia found that the use of chlorine decreased with higher prices, but this decline was partially offset by better targeting of the product to families who were more likely to use it. Additionally, there was no evidence that higher offer prices screened out poorer or less educated households.

It is unclear whether a gender-differentiated intervention may be more effective in reducing some or all types of crime. To better understand this issue, researchers are working with the local police force in two districts in Pakistan to study its effects on trust levels and occurrence of crime.

To study the effect of increased social pressure on turnout, researchers sent households one of four randomly selected mailings eleven days before Michigan’s August 2006 primary election. All four mailings increased turnout, but informing households of their neighbors’ past voting records raised turnout among registered voters by 8.1 percentage points, making the mailing about as effective as in-person canvassing.

Researchers from Yale University conducted a randomized evaluation to examine the effects of political party identification on political attitudes and opinions. Participants in the study who received a printed letter indicating that they must register with a political party to vote in an upcoming election were more likely to affiliate with a party, change their views on political issues, and change their voting behavior.

Researchers measured the impact of receiving phone calls on registered voters’ likelihood of voting in general elections in the United States. The study found that non-partisan, get-out-the-vote (GOTV) phone calls had no effect on voter turnout.

By subjecting the papers to an electronic anti-plagiarism program, researchers found that the tutorial significantly reduced the likelihood of plagiarism, particularly among students with lower college entrance scores who had the highest rates of plagiarism. A follow-up survey suggests that the intervention reduced plagiarism by increasing student knowledge rather than by increasing the perceived probabilities of detection and punishment.
