“Asset Pricing in a Production Economywith Heterogeneous Investors” by Jin ZHANG
University of Hong Kong
This paper is a theoretical examination of the stochastic behavior of equilibrium asset prices in an economy consisting of a production process controlled by a state variable representing the state of technology. The investors with different degrees of risk aversion and time preferences trade and lend among themselves in order to maximize their individual utilities of life time consumption. The allocation of wealth fluctuates randomly among them and act as state variables against which each investor wants to hedge. This hedging motive complicates the investor's portfolio choice and the equilibrium in the production economy. A general method of constructing equilibrium asset prices is developed and the wealth effect in the general equilibrium is discussed.
