When do beliefs, about the values of others, affect tax compliance and honesty?

When do ex-ante beliefs about the values of others affect compliance and honesty? To answer this question, we conduct an experiment, in which subjects face repeated trade-offs between monetary gain and honesty. As a source of exogenous variation, half of the subjects were told that their choices would be shared with the other subjects in the room. We show that: 1) the belief that peers value honesty more, (only) leads to a crowding-in effect when these subjects know that their choices will become public. 2) the crowding-in effect is dependent on ex-ante beliefs about the values of others
