We investigate the adverse selection problem where a principal delegates multiple tasks to individuals. The individuals form a group as a single agent and share their private signals in order to maximize their average payoff. We characterize the virtually implementable social choice functions by...

We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) that restricts the message spaces. The principal...
