We study the perfect Bayesian equilibrium of a model of learning over a general social network. Each individual receives a signal about the underlying state of the world, observes the past actions of a stochastically-generated neighborhood of individuals, and chooses one of two possible actions....

The daunting complexity of important financial decisions can lead to procrastination. We evaluate a low-cost intervention that substantially simplifies the retirement savings plan participation decision. Individuals received an opportunity to enroll in a retirement savings plan at a pre-selected...

Since 1997, states have begun to make criminal history records publicly available over the Internet. This paper exploits this previously unexamined variation to identify the effect of expanded employer access to criminal history data on the labor market outcomes of ex-offenders and...

We present results about the effects of observing others' choices, called observational learning, on individuals' behavior and subjective well-being in the context of restaurant dining from a randomized natural field experiment. Our experimental design aims to distinguish observational learning...

This paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees' decisions to enroll in a Tax Deferred Account (TDA) retirement plan within a large university. The experiment encouraged a random sample of employees in a subset of...

During the summer of 2005, the Big Three U.S. automobile manufacturers offered a customer promotion that allowed customers to buy new cars at the discounted price formerly offered only to employees. The initial months of the promotion were record sales months for each of the Big Three firms,...

This paper investigates whether peer effects play an important role in retirement savings decisions. We use individual data from the staff of a university to study whether individual decisions to enroll in a Tax Deferred Account plan sponsored by the university (and the choice of the mutual fund...

We estimate a Bayesian learning model in order to assess the value of health plan performance information and the extent to which the explicit provision of information about product quality alters consumer behavior. We take advantage of a natural experiment in which health plan performance...

This paper uses detailed data on retail pharmacy transactions to make inferences about the nature and intensity of consumer search for prescription drugs. Prescription prices exhibit patterns that should, in principle, induce search: in particular, prices vary widely across stores, and stores'...

This paper explores the level and dispersion of premiums paid for individual health insurance by comparing asking price' data posted on an electronic insurance exchange with survey data on premiums actually paid in the period just before the advent of electronic exchanges. The primary...
