Task Discretion, Labor-market Frictions, and Entrepreneurship

Each job can be performed in several ways, which we call tasks An agent's performance at a task is informative about his productivity at different tasks. But tasks are not contractible: choosing tasks is the prerogative of management within firms, and of the agent if he is an entrepreneur. Firms will invest in the discovery of their workers' productivity at different tasks only if they cannot easily move to other firms. Therefore, labor-market frictions determine whether learning an agent's talent occur within firms, or whether an agent may become an entrepreneur to acquire task discretion.
