Discussion Paper
Bank-Intermediated Arbitrage

Since the 2007-09 financial crisis, the prices of closely related assets have shown persistent deviations?so-called basis spreads. Because such disparities create apparent profit opportunities, the question arises of why they are not arbitraged away. In a recent Staff Report, we argue that post-crisis changes to regulation and market structure have increased the costs to banks of participating in spread-narrowing trades, creating limits to arbitrage. In addition, although one might expect hedge funds to act as arbitrageurs, we find evidence that post-crisis regulation affects not only the ...

Empirical evaluation of asset pricing models: arbitrage and pricing errors over contingent claims

In a 1997 paper, Hansen and Jagannathan develop two pricing error measures for asset pricing models. The first measure is the maximum pricing error on given test assets, and the second measure is the maximum pricing error over all possible contingent claims. We develop a simulation-based Bayesian inference of the pricing error measures. Although linear time-varying and multifactor models are widely reported to have small pricing errors on standard test assets, we demonstrate that these models can have large pricing errors over contingent claims because their stochastic discount factors are ...

Duality and arbitrage with transactions costs: theory and applications

Recent advances in duality theory have made it easier to discover relationships between asset prices and the portfolio choices based on them. But this approach to arbitrage-free securities markets has yet to be extended and applied to economies with transactions costs. This paper does so, within the context of a general state-preference model of securities markets. Several applications are developed to illustrate the nature of the theory and its potential to resolve a host of issues surrounding the effects of transactions costs on securities markets.

The dynamic relationship between the federal funds rate and the Treasury bill rate: an empirical investigation

This article examines the dynamic relationship between two key U.S. money market interest rates - the federal funds rate and the 3-month Treasury bill rate. Using daily data over the period 1974 to 1999, we find a long-run relationship between these two rates that is remarkably stable across monetary policy regimes of interest rate and monetary aggregate targeting. Employing a non-linear asymmetric vector equilibrium correction model, which is novel in this context, we find that most of the adjustment towards the long-run equilibrium occurs through the federal funds rates. In turn, there is ...

Exchange-rate puzzles in a model with arbitrage.

This paper documents the implications of arbitrage costs on the behavior of exchange rates in an open-economy liquidity model. The main motivation behind the paper is the growing evidence that the well-documented departures from purchasing power parity are due to a failure of the law of one price. The paper quantifies the importance of arbitrage costs for the variability, persistence, and autocorrelation of real and nominal exchange rates and compares the results with those of a model with nominal rigidities and firms pricing to market; second, the paper studies the impact of currency risk ...

Around and Around: The Expectations Hypothesis

We show how to construct arbitrage-free models of he 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, Ingersoll, and Ross (CIR, 1981) that only the so-called local expectations hypothesis could hold. We generalize that example in three ways: (i) We characterize the U--EH in terms of forward rates; (ii) we extend this characterization to a class of expectations hypotheses that includes all of those considered ...

Working Paper
An international arbitrage pricing model with PPP deviations

This paper develops an intertemporal, international asset pricing model for use in applied theoretical and empirical research. An important feature of the model is that it incorporates both stochastic inflation rates and stochastic Purchasing Power Parity deviations (PPP). The model derives the equilibrium real return on assets, and obtains empirically tractable reduced form equations which can be used to examine such issues as capital market segmentation, currency substitution, exchange rate volatility, and the forward exchange market's risk premium. Mechanically, the model begins as a ...
