Learning, rare events, and recurrent market crashes in frictionless economies without intrinsic uncertainty

Article Abstract:

The presence of speculative trade in a dynamically complete environment was confirmed using a standard dynamic asset pricing model. It was revealed that the presence of sunspots tends to create a certain degree of uncertainty in markets where agents are long-lived. It was further shown that despite the homogenity of factors and beliefs, market crashes are still likely to prevail due to the tendency of wealth to bounce back and fourth from one agent to another.
