Is the market price of risk infinite?

Author

Listed:
  • Cogley, Timothy

Abstract

In a Bayesian model, a rational-expectations Euler equation involves a learning wedge that disconnects the consumer's IMRS from the rational-expectations pricing kernel. The wedge is extremely volatile and explains the high volatility of the rational-expectations pricing kernel.
