  I study the heterogeneity of credence goods provision in taxi drivers taking
detours in New York City. First, I document that there is significant detouring
on average by drivers. Second, there is significant heterogeneity in cheating
across individuals, yet each individual's propensity to take detours is stable:
drivers who detour almost always detour, while those who do not detour almost
never do. Drivers who take longer detours on each trip also take such trips
more often. Third, cultural attitudes plausibly explain some of this
heterogeneity in behavior across individuals.
