Updating Wealth in an Asset Pricing Model with Heterogeneous Agents
نویسندگان
چکیده
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 heterogeneous beliefs are considered: fundamentalists and chartists. The model results in a nonlinear three-dimensional dynamical system, which we have studied in order to investigate complicated dynamics and to explain wealth distribution among agents in the long run.

An Adaptive Model on Asset Pricing and Wealth Dynamics with Heterogeneous Trading Strategies
This paper develops an adaptive model on asset pricing and wealth dynamic of a financial market with heterogeneous agents and examines the profitability of momentum and contrarian trading strategies. In order to characterize asset price, wealth dynamics and rational adaptiveness arising from the interaction of heterogeneous agents with CRRA utility, an adaptive discrete time equilibrium model i...
متن کاملWealth Distribution in an Asset Pricing Model: the Role of the Switching Mechanism
We present an asset pricing model with heterogeneous agents trading in a Walrasian scenario. Fractions of agents are updated at any time and their wealth is updated not only as a consequence of portfolio growth of agents adopting the same strategy, but also due to the flow of new agents. After introducing the belief types, rational and chartists, the model is built to investigate the role of th...
متن کاملAn Analysis to Wealth Distribution Based on Sugarscape Model in an Artificial Society
In this paper an artificial society is being assumed as a multi agents system. A sugarscape model consisting of a cellular landscape of resources is used to form an interaction among the agents of the population. In the model, agents find the resources to survive. They are supposed to move and search and because of this movement, an evolutionary social behavior will develope. From model analys...
متن کاملComplex 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 کاملAsset Prices and Wealth Inequality∗
This paper uses recently available data on the top of the wealth distribution to study the relationship between asset prices and wealth inequality. I document three stylized facts: (1) the share of wealth invested in equity increases sharply in the right tail of the wealth distribution, (2) when stock market returns are high, wealth inequality increases and (3) higher wealth inequality predicts...
