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,...

When preferences are homothetic, utility can be expressed in terms of current consumption and a variable that captures all information about future opportunities. We use this observation to express the differential equation that characterizes utility as a restriction on the information variable...

We show how to construct models of the term structure of interest rates in which the expectations hypothesis holds. McCulloch (1993) presents such a model, thereby contradicting an assertion by Cox, Ingersoll, and Ross (1981), but his example is Gaussian and falls outside the class of...

With a stochastic general equilibrium model, we highlight the role of both monetary policy and banks in determining the relationship between the federal funds rate and bank reserves. Monetary policy consists of a stochastic upward-sloping supply schedule for reserves, along with a discount...

We define rational bubbles to be securities with payoffs occurring in the infinitely distant future and investigate the behavior of bubble values. We extend our analysis to a setting of uncertainty. In an infinite-horizon arbitrage-free model of asset prices, we interpret the money market...

This paper studies recent models of the liquidity effect of money on interest rates to determine if a systematic relationship between liquidity shocks and the economy could affect the average real interest rate.
