Investors seek to hedge against interest rate risk by taking long or short positions on bonds of different maturities. We study changes in risk taking behavior in a low interest rate environment by estimating a market stochastic discount factor that is non-linear and therefore consistent with...

The estimation of discount factors is a central issue in empirical finance, particularly in the literature on excess volatility. In particular, it is difficult to find empirical discount factors that are volatile enough to account for fluctuations in asset prices. This paper constructs discount...

This paper develops a simple methodology to test for asset integration, and applies it within and between American stock markets. Our technique relies on estimating and comparing expected risk-free rates across assets. Expected risk-free rates are allowed to vary freely over time, constrained...
