This is important for policy:if the answer is yes, it provides a means of increasing the efficacy of intervention (e.g., by selectively timing intervention trades). Central bankers have long suggested that market expectations are at times “ripe” for coordinated adjustment, particularly when new public information arrives. Implicit in this view is the idea that agents draw different conclusions from common macro economic data, making transactions at these times especially valuable for measuring expectations…
