This chapter provides an overview of recent models of heterogeneous expectations in macroeconomics. We begin with a description of household behavior in an environment with features common to many models in asset pricing, monetary theory, and New Keynesian macroeconomics. We demonstrate issues...

A restricted-perceptions equilibrium exists in which risk-averse agents believe stock prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk, bubbles and crashes arise. These effects are stronger when agents allow for ARCH in excess returns.

We consider a simple pure exchange economy with two assets, one riskless, yielding a constant return on investment, and one risky, paying a stochastic dividend. Trading takes place in discrete time and in each trading period the price of the risky asset is fixed by imposing market clearing...

In this paper we study the dynamics of a simple asset pricing model describing the trading activity of heterogeneous agents in a stylized market. The economy in the model contains two assets: a bond with risk-less return and a dividend paying stock. The price of the stock is determined through...

In this paper we study the dynamics of a simple asset pricing model describing the trading activity of heterogeneous agents in a "stylized" market. The economy in the model contains two assets: a bond with risk-less return and a dividend paying stock. The price of the stock is determined through...

We consider a simple pure exchange economy with two assets, one riskless, yielding a constant return, and one risky, paying a stochastic dividend, and we assume trading to take place in discrete time inside an endogenous price formation setting. Traders demand for the risky asset is expressed as...
