Pay enough, don’t pay too much or don’t pay at all? An empirical study of the non-monotonic impact of incentives on job satisfaction

This paper attempts to test the non-monotonic effect of monetary incentives on job satisfaction. Specifically, 8 waves (1998-2005) of the British Household Panel Survey (BHPS) are used to investigate the ceteris paribus association between the intensity of bonus/profit-sharing payments and the utility derived from work. After controlling for individual heterogeneity biases, it is shown that relatively ‘small’ bonuses exert a significant negative effect on worker satisfaction. In contrast, job utility is found to rise only in response to ‘large’ bonus payments, primarily in skilled, non-unionized private sector jobs. The empirical evidence of the paper is therefore consistent with a ‘V-effect’ of incentives, suggesting that employers wishing to motivate their staff should indeed “pay enough or don’t pay at all”.
