The heterogeneous effects of bonus pay on performance outcomes : evidence from personnel data ; conference paper

This study uses rich information on performance outcomes to estimate the effect of bonus pay on worker productivity. We use a policy discontinuity in the call centre of a multi-national telephone company in which management introduced monetary bonuses upon achieving pre-defined performance thresholds. The results show that the bonus is associated with an increase of a third of a standard deviation in the underlying performance outcome. This effect is mostly driven by low-ability agents whose performance improvement is about three times as large as for the average worker. Conversely, the treatment effect for high-ability agents is even negative. Furthermore, we find that other, non-incentivised performance outcomes are positively affected.
