We investigate information aggregation and competition in a delegationframework. An uninformed principal is unable to perform a task herself andmust choose between one of two biased and imperfectly informed experts. Inthe focal equilibrium, experts exaggerate their biases, anticipating...

We propose a new decomposition of the realized covariance matrix into components based on the signs of the underlying high-frequency returns. Under an asymptotic setting in which the sampling interval goes to zero, we derive the asymptotic properties of the resulting realized semicovariance...
