We analyze if intergenerational teams reveal workers' productivities. Some uncertainty on agents' productivities persists when (i) each agent must work independently, or (ii) technological shocks are agent-specific in compulsory teams. However, when technological shocks are team-specific in compulsory teams, each worker's productivity is revealed. When agents choose to work independently or in teams, that problem falls in the class of dynamic games. Elective teams are preferred by high-productivity young workers when the technological shocks are agent-specific, and maximize the expected utility of a young worker when shocks are team-specific.
