Gd. Jenkins et al., ARE FINANCIAL INCENTIVES RELATED TO PERFORMANCE - A METAANALYTIC REVIEW OF EMPIRICAL-RESEARCH, Journal of applied psychology, 83(5), 1998, pp. 777-787
The relationship of financial incentives to performance quality and qu
antity is cumulated over 39 studies containing 47 relationships. Finan
cial incentives were not related to performance quality but had a corr
ected correlation of .34 with performance quantity. Setting (laborator
y, field, experimental simulation) and theoretical framework moderated
the relationship, but task type did not.
