Evolution of Wealth and Asset Prices in Markets with Case-Based Investors
AbstractI analyze whether case-based decision makers (CBDM) can survive in an assetmarket in the presence of expected utilitymaximizers. Conditions are identified, under which the CBDM retain a positive mass with probability one. CBDM can cause predictability of asset returns, high volatility and bubbles. It is found that the expected utility maximizers can disappear from the market for a finite period of time, if the mispricing of the risky asset caused by the case-based decision-makers aggravates too much. Only in the case of logarithmic expected utility maximizers do the case-based decision makers disappear from the market for all parameter values.
