Following FCC pressure to end bill shock, cellular carriers now alert customers when they exceed usage allowances. We estimate a model of plan choice, usage, and learning using a 2002-2004 panel of cellular bills. Accounting for firm price adjustment, we predict that implementing alerts in...

By April 2013, the FCC's recent bill-shock agreement with cellular carriers requires consumers be notified when exceeding usage allowances. Will the agreement help or hurt consumers? To answer this question, we estimate a model of consumer plan choice, usage, and learning using a panel of...

Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of group diversity on group risk taking. I measure econometrically the effects of various aspects of subjects’ diversity: nationality, language, university degree and gender. I...

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...

We look at the links between the Digit Ratio - the ratio of the length of the index finger to the length of the ring finger – for both right and left hands, and giving in a Dictator Game. Unlike previous studies with exclusively Caucasian subjects, we recruited a large, ethnically diverse...

For many goods and services, such as cellular-phone service and debit-card transactions, the price of the next unit of service depends on past usage. As a result, consumers who are inattentive to their past usage but are aware of contract terms may remain uncertain about the price of the next...

We use university parking permits to study how firms and employees split the value of employee benefit tax subsidies. Starting in 1998, the IRS allowed employees to pay for parking passes with pre-tax income. This subsidized the parking pass purchases of faculty and staff, but did not affect...
