We combine survey data on friendship networks and individual characteristics with experimental observations from dictator games. Dictator offers are primarily explained by social distance giving follows a simple inverse distance law. While student demographics play a minor role in explaining offer amounts, individual heterogeneity is important for network(More)
It is conventional wisdom that it is possible to reduce exposure to indoor air pollution, improve health outcomes, and decrease greenhouse gas emissions in the rural areas of developing countries through the adoption of improved cooking stoves. This belief is largely supported by observational field studies and engineering or laboratory experiments.(More)
We combine data collected on friendship networks and individual characteristics with experimental observations from a sequence of dictator games run at an all-girls school in Pasadena, California. Our analysis provides two sets of insights. First, we find that dictator giving is primarily explained by social distance, defined as the length of the shortest(More)
Pricing policy for any experience good faces a key tradeoff. On one hand, a price reduction increases immediate demand and hence more people learn about the product. On the other hand, lower prices may serve as price anchors and, through a comparison effect, decrease subsequent demand. This tension is particularly important for the distribution of health(More)
ngoing efforts to find the best method for predicting recessions leave many questions unresolved. Existing papers propose a variety of indicators and modeling techniques, yet overall forecast accuracy has been mixed (see, for example, Stock and Watson [2003]). One approach with an excellent track record is the term spread model of Estrella and Hardouvelis(More)
INTRODUCTION HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies,(More)
We review the statistical models applied to test for heterogeneous treatment effects in the recent empirical literature, with a particular focus on data from randomized field experiments. We show that testing for heterogeneous treatment effects is highly common, and likely to result in a large number of false discoveries when conventional standard errors(More)
