Diagnostic Bubbles

Diagnostic Bubbles, Andrei Shleifer, December 2018, Paper, “We introduce diagnostic expectations into a standard setting of price formation in which investors learn about the fundamental value of an asset and trade it.

With diagnostic (but not with rational) expectations, these mechanisms lead to price paths exhibiting three phases: initial underreaction, followed by overshooting (the bubble), and finally a crash. With learning from prices, the model generates price extrapolation as a byproduct of fast moving beliefs about fundamentals, which lasts only as the bubble builds up. When investors speculate, even mild diagnostic distortions generate substantial bubbles.Link
