When the rich do (not) trust the (newly) rich: Experimental evidence on the effects of positive random shocks in the trust game

We study behavior in a trust game where first‐movers initially have a higher endowment than second‐movers but the occurrence of a positive random shock can eliminate this inequality by increasing the endowment of the second‐mover before the decision of the first‐mover. We find that second‐movers return less (i.e., they are less trustworthy) when they have a lower endowment than first‐movers, compared with the case in which first and second‐movers have the same endowment. In addition, second‐movers who experience the positive shock return more than second‐movers who have the same endowment as the first‐mover from the outset. First‐movers do not seem to anticipate this behavior from second‐movers. They send less to second‐movers who benefited from a shock. Our findings suggest that in addition to the distribution of the endowments the source of this distribution plays an important role in determining the levels of trust and trustworthiness.
