Abstract: |
Financial markets are overwhelmed by daily announcements. We use experimental
asset markets to assess the impact of uninformative communications on asset
prices and trading volumes. We deliver uninformative messages in standard
experimental asset markets and find that trading volumes and prices are
impacted by these messages. In particular, the release of a pre-announced
preset message to traders “The price is too high” in predetermined trading
periods decreases the amplitude and duration of bubbles. Also, the release of
the messages “The price is too high” or “The price is too low” reduces trading
volume with inexperienced subjects. |
