Abstract
Innovative workplace practices based on multi-tasking and ICT that have
been diffusing in most OECD countries since the 1990s have strong conse-
quences on working conditions. Available data show together with the emer-
gence of new organizational forms like multi-tasking, the increase in the pro-
portion of workers employed in managerial occupation and the increase in
skill requirements. This paper proposes a theoretical model to analyze the
optimal number of tasks per worker when switching to multi-tasking raises
coordination costs between workers and between tasks. Firms can reduce
coordination costs by assigning more workers to human resources manage-
ment. Human capital is endogenously accumulated by workers. The model
reproduces pretty well the regularities observed in the data. In particular, ex-
ogenous technological accelerations tend to increase both the number of tasks
performed and the skill requirements, and to raise the fraction of workers de-
voted to management.
