Endogenous #uctuations in a simple asset pricing model with heterogeneous agents

چکیده
In this paper we study the adaptive rational equilibrium dynamics in a simple asset pricing model introduced by Brock and Hommes (System Dynamics in Economic and Financial Models, Wiley, Chichester, 1997, pp. 3}44; Journal of Economic Dynamics and Control, 22, 1998, 1235}1274). Traders have heterogeneous expectations concerning future prices and update their beliefs according to a risk adjusted performance measure and to market conditions. Further, also their expectations about conditional variances of returns vary over time. We show that even for the simple case where agents can only choose between two di!erent predictors complicated dynamics arise and we analyse the bifurcation routes to chaos.

Complex dynamics in equilibrium asset pricing models with boundedly rational, heterogeneous agents
We study a simple model based upon the Lucas framework where heterogeneous agents behave rationally in a fully intertemporal setting but do not know other investors’ personal preferences, wealth or investment portfolios. As a consequence, agents initially do not know the equilibrium asset pricing function and must make guesses which they update via adaptive learning with constant gain. We demon...
متن کاملHeterogeneous beliefs and routes to chaos in a simple asset pricing model
This paper investigates the dynamics in a simple present discounted value asset pricing model with heterogeneous beliefs. Agents choose from a finite set of predictors of future prices of a risky asset and revise their ‘beliefs’ in each period in a boundedly rational way, according to a ‘fitness measure’ such as past realized profits. Price fluctuations are thus driven by an evolutionary dynami...
متن کاملHigher moments portfolio Optimization with unequal weights based on Generalized Capital Asset pricing model with independent and identically asymmetric Power Distribution
The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...
متن کاملNonlinear Adaptive Beliefs and the Dynamics of Financial Markets: The Role of the Evolutionary Fitness Measure
We introduce a simple asset pricing model with two types of adaptively learning traders, fundamentalists and technical traders. Traders update their beliefs according to past performance and to market conditions. The model generates endogenous price uctuations and captures some stylized facts observed in real returns data, such as excess volatility, fat tails of returns distributions, volatilit...
متن کاملUpdating Wealth in an Asset Pricing Model with Heterogeneous Agents
We consider an asset-pricing model with wealth dynamics in a market populated by heterogeneous agents. By assuming that all agents belonging to the same group agree to share their wealth whenever an agent joins the group or leaves it , we develop an adaptive model which characterizes the evolution of wealth distribution when agents switch between different trading strategies. Two groups with he...
