Optimal contracts with randomly arriving tasks

Abstract

Workers rarely perform exactly the same tasks every day. Instead, their daily workload may change randomly over time to comply with the uctuating needs of the organiza- tion where they are employed. In this paper, we show that this typical randomness in workplaces has a striking eect on the structure of long-term employment contracts. In particular, simple intertemporal variability in the worker's tasks is sucient to gen- erate a rich promotion-based dynamics in which, occasionally, the worker receives a (permanent) wage raise and his future work requirements are reduced.
