Evaluating a Landmine Action ex-combatant reintegration program in Liberia Baseline Report

Project Description: From 2009 to 2011, IPA will follow more than 1,500 ex-combatants via surveys and an in-depth ethnographic study. Landmine Action will draw half of these youth out of illegal sectors, train them in agriculture, provide counseling, and resettle graduates in their home communities, where they will be allocated land to raise crops and animals for cash.

Remedying education: Evidence from two randomized experiments in India

Project Description: Many efforts to improve school quality by adding school resources have proven to be ineffective. This paper presents the results of two experiments conducted in Mumbai and Vadodara, India, designed to evaluate ways to improve the quality of education in urban slums. A remedial education program hired young women from the community to teach basic literacy and numeracy skills to children lagging behind in government schools.

Principle Investigators: Abhijit Banerjee, Shawn Cole, Esther Duflo, Leigh Linden.

 Many Children Left Behind? Textbooks and Test Scores in Kenya

Project Description: A randomized evaluation suggests that a program which provided official textbooks to randomly selected rural Kenyan primary schools did not increase test scores for the average student. The results are consistent with the hypothesis that the Kenyan education system and curricular materials are oriented to the academically strongest students rather than to typical students

Credit Elasticities in Less-Developed Economies: Implications for Microfinance

Project Description: Policymakers often prescribe that microfinance institutions increase interest rates to eliminate their reliance on subsidies. This strategy makes sense if the poor are rate insensitive: then microlenders increase profitability (or achieve sustainability) without reducing the poor's access to credit.

Does Price Matter in Charitable Giving? Evidence from a Large-Scale Natural Field Experiment

Project Description: The authors conducted a natural field experiment to further our understanding of the economics of charity. Using direct mail solicitations to over 50,000 prior donors of a nonprofit organization, they tested the effectiveness of a matching grant on charitable giving. They find that the match offer increases both the revenue per solicitation and the response rate.

Using Experimental Economics to Measure Social Capital and Predict Financial Decisions

Project Description: Questions remain as to whether results from experimental economics are generalizable to real decisions in nonlaboratory settings. Furthermore, questions persist about whether social capital helps mitigate information asymmetries in credit markets.

Are Women More Credit Constrained? Experiment Evidence on Gender and Microenterprise Returns

Project Description: This paper analyzes data from a randomized experiment on mean returns to capital in Sri Lankan micro-enterprises. The findings show greater returns among men than among women; indeed, returns were not different from zero for women. The authors explore different explanations for the lower returns among female owners, and find no evidence that the gender gap is explained by differences in ability, risk aversion, or entrepreneurial attitudes. Differential access to unpaid family labor and social constraints limiting sales to local areas are not important.

Does the Media Matter? A Field Experiment Measuring the Effect of Newspapers on Voting Behavior and Political Opinions

Project Description: A field experiment was conducted to measure the effect of exposure to newspapers on political behavior and opinion. No effect of either paper on political knowledge, stated opinions, or turnout in post-election survey and voter data was found. However, receiving either paper led to more support for the Democratic candidate, suggesting that media slant mattered less in this case than media exposure. Some evidence from voting records also suggests that receiving either paper led to increased 2006 voter turnout. (JEL D72, L82)
