Asset price volatilities and trading volumes in heterogeneous agent economies


  • Costas Xiouros

    () (Finance and Business Economics University of Southern California)


Apart from the risk premium of equity over bonds, volatility of asset prices and trading volumes are two aspects of the already developed general equilibrium asset pricing theory that fail to show any resemblance with real data. The assumption of agent homogeneity has been relaxed in a number of studies where agents face uninsurable income shocks but fail to provide a consistent explanation that addresses all issues. This study assumes a dynamically complete asset market with two states and two assets, where the agents are allowed to be heterogeneous either in terms of their risk preferences, or in terms of their beliefs for the probabilities of the exogenous shock. The assumption that the (logarithm of the) aggregate dividend follows an autoregressive process with an iid state dependent shock, helps us construct a non-trivial equilibrium in which the endogenously determined wealth distribution across agents is part of the economy's state vector. Qualitative results show that this kind of setup works in the right direction in all issues addressed, while quantitative results are produced using a projection method as well as a variant of the Krusell and Smith method
