Abstract
We incorporate unawareness into the delegation model and study the communication outcome followed by delegation between a financial expert and an investor. The expert has superior awareness of the possible states of the world, and decides whether to reveal some of them to the investor. Under the uniform-quadratic setting and some regular restrictions on the investor's belief updating outcome, our result implies that the expert would reveal all the possible states to the investor if the investor is aware of a large set of possible states, while would only disclose partially or even nothing if the investor is only aware of a small set of possible states.
