Information is a driver of crises and of market liquidity. In periods of stress, finding liquidity is difficult and illiquidity increases mostly because of information. The video was recorded in April 2016 at the First Annual Spring Symposium on Financial Economics organised by CEPR and the Brevan Howard Centre at Imperial College.
