Abstract

Applying a social exchange perspective, three studies examine how the effects of perceived orga-nizational support (POS) and perceived supervisor support (PSS) on performance and commit-ment are constrained by pay contingency. Study 1 shows a negative interaction between POS and pay contingency and a positive interaction between PSS and pay contingency in their effects on performance and nonsignificant interactions regarding commitment. In Studies 2 and 3, which were conducted in high pay contingency field settings, performance was affected by PSS but not by POS, whereas commitment was affected by POS but not by PSS. Implications of these moderation effects are discussed.
