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 deviation of the market price from the...

We develop a parsimonious model of bubbles based on the assumption of imprecisely known market depth. In a speculative bubble, traders drive the price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously unknown date, the...

We develop a model of rational bubbles based on leverage and the assumption of an imprecisely known maximum market size. In a bubble, traders push the asset price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously...

Although there are many stock market anomalies which the Efficient Market Hypothesis (EMH) finds difficult to explain, it also has its strengths, and so far no alternative hypothesis has been developed which can explain what the EMH explains but which can also do a better job in explaining the...

We develop a model of rational bubbles based on leverage and the assumption of an imprecisely known maximum market size. In a bubble, traders push the asset price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously...

We develop a model of rational bubbles, based on the assumptions of an unknown potential market size and delegation of investment decisions. In a bubble, the price of an asset rises above its steady-state value, which must be justified by rational expectations about possible future price...
