Zusammenfassung:
Previous work has shown that unobservable random shocks on output have a detrimental effect on effort provision in short-term ('static') employment relationships. Given the prevalence of long-term ('dynamic') relationships in firms, we investigate whether the impact of shocks is similarly pronounced in gift-exchange relationships where the same principalagent pair interacts repeatedly. In dynamic relationships, shocks have a significantly less pronounced negative effect on the agent's effort provision than in static relationships. In an attempt to identify the drivers for our results we find that the combination of a repeatedgame effect and a noise-canceling effect is required to avoid the detrimental effects of unobservable random shocks on effort provision.
