We show how to construct arbitrage-free models of the term structure of interest rates in which various expectations hypotheses can hold. McCulloch (1993) provided a Gaussian non-Markovian example of the unbiased expectations hypothesis (U--EH), thereby contradicting the assertion by Cox,...

How does the additional uncertainty associated with noisy economic data affect business cycle fluctuations? I use a simple variant of the neoclassical growth model to show that the answer depends crucially on the assumed expectation-formation capabilities of agents. Under efficient signal...

This paper develops algorithms that solve for optimal discretionary and optimal pre-commitment policies in rational-expectations models. The techniques developed are simpler to apply than existing methods; they do not require identifying and separating predetermined variables from jump...

This paper explores various strategies for estimating rational expectations models when the trend specification is uncertain. One approach modified the likelihood function in order to reduce the influence of low-frequency dynamics. Hansen and Sargent (1993) conjectured that this would have...

The amount of information in the yield curve for forecasting future changes in short rates varies with the maturity of the rates involved. Indeed, spreads between certain long and short rates appear unrelated to future changes in the short rate--contrary to the rational expectations hypothesis...

The relationship between asset demand and information quality in rational expectations economies is analyzed. First we derive a number of new summary descriptive statistics that measure four basic characteristics of investment style: asset selection, market timing, aggressiveness, and...
