INFLUENCE OF FINITE CAPITAL IN THE CONT–BOUCHAUD-MODEL FOR MARKET FLUCTUATIONS

Introducing a finite capital of the shareholders in the Cont–Bouchaud-model leads to a partially realistic wealth distribution for middle positions in the wealth hierarchy. However, the number of poor shareholders is too small and the capitals of the wealthiest ones are too low. Also variation of the simulation time, of the activity and consideration of the fundamentalists' influence does not give data in agreement with reality.
