Economic theory suggests that, when designing aid programs, ordeal mechanisms that impose differential costs for rich and poor can induce self-selection and hence improve targeting ("self-targeting"). We first re-examine this theory and show that ordeal mechanisms may actually have theoretically...

We use unique data from 600 Indonesian communities on what individuals know about the poverty status of others to study how network structure influences information aggregation. We develop a model of semi-Bayesian learning on networks, which we structurally estimate using within-village data....

The DeGroot model has emerged as a credible alternative to the standard Bayesian model for studying learning on networks, offering a natural way to model naive learning in a complex setting. One unattractive aspect of this model is the assumption that the process starts with every node in the...
