摘要:We introduce new treatments of a voluntary contribution mechanism with opportunities
to punish, to see how contributions and punishments change when (a) each dollar lost in
punishment must be awarded to another team member and/or when (b) obtaining
information on individuals¡¯ contributions is a costly choice. Conjectures that tying
punishments to rewards might reduce punishment of high contributors (perverse
punishment) or increase overall punishing are not completely born out, but innovation (a)
nonetheless succeeds in making the net punishment of high contributors much less
common because they receive enough rewards to offset punishment. A surprise finding
is that innovation (b) also decreases the incidence of misdirected punishment, since high
contributors do more monitoring than low ones while low contributors do most of the
perverse punishing. Both innovations raise both contributions and earnings relative to the
familiar VCM-with-punishment treatment.
