This experiment compares the price dynamics and bubble formation in an asset market with a price adjustment rule in three treatments where subjects (1) submit a price forecast only, (2) choose quantity to buy/sell and (3) perform both tasks. We find that bubbles emerge in all these treatments, but to a larger degree in treatment (2) and (3). Our result confirms that bubble formation is a robust finding in markets with positive expectation feedback. We also find some repeated ``super bubbles'' where the price is 3 times larger than the fundamental value, which were not seen in former experiments.
