of a higher depreciation rate, which makes inventory riskier than fixed capital. In support of this result, our empirical work documents that risk premia, rather than real interest rates, are negatively related to future inventory growth. This relation is highly significant and robust to a...

Building on the approach of Duffie and Kan (1996) who use finite maturity yields as the state vector, we propose a new representation of affine models in which the state vector is composed of infinitesimal maturity yields and their quadratic covariations. Because these variables possess...

This paper is based on the premise that knowledge about the alphas of one set of funds will influence an investor's beliefs about other funds. This will be true insofar as an investor's expectation about the performance of a fund is partly a belief about the abilities of mutual fund managers as...

This study confronts the growing evidence that multiple sources of priced risk appear necessary to explain the expected returns of equity index options. A general class of nonlinear latent factor models is estimated using a data set of over 32,000 daily return observations on Samp;P 500 index...

This paper introduces a new Bayesian method for the analysis of discretely sampled diffusion processes. The method, which is termed high frequency augmentation (HFA), is a simple numerical method that is applicable to a wide variety of univariate or multivariate diffusion processes. It is...

We find that option returns are significantly lower over nontrading periods, the vast majority of which are weekends. Our evidence suggests that nontrading returns cannot be explained by risk, but are rather the result of widespread and highly persistent option mispricing driven by the incorrect...

We argue that anomalies may experience prolonged decay after discovery and propose a Bayesian framework to study how that impacts portfolio decisions. Using the January effect and short-term index autocorrelations as examples of disappearing anomalies, we find that prolonged decay is empirically...

We examine the relation between inventory investment and the cost of capital in the time series and the cross section. We find consistent evidence that risk premia, rather than real interest rates, are strongly negatively related to future inventory growth at the aggregate, industry, and firm...
