Task Assignments and Incentives: Generalists versus Specialists ∗ Suraj Prasad † January 17, 2009 Abstract I develop an agency model of job assignments where jobs differ based on the breadth of tasks. A tradeoff between task complementarities and relative abilities of workers results in those with balanced skills being assigned to multi-task jobs. The same tradeoff between complementarities and relative abilities also influences incentives to sort privately informed workers to jobs. I then draw on a variety of sources (survey data, case studies, and anecdotal evidence) to suggest that relative abilities and multi-tasking play an important role in managerial assignments of non-academic research scientists. ∗ I would like to thank two anonymous referees, Jennifer Reinganum (the editor), as well as Gaetano Antinolfi, Edward Greenberg, Stephanie Lau, Glenn MacDonald, Kieron Meagher, Charles Moul, John Nachbar, Hideo Owan, Bruce Petersen, Bill Schworm, Randy Silvers and Michael Waldman for helpful comments.
