This paper shows that preferences alone cannot explain the patterns reported in the literature.

This paper proposes a novel methodology, based on the Common Principal Component analysis, allowing one to estimate the factors driving the term structure of interest rates, in the presence of time-varying covariance structure.

Many economic and econometric applications require the integration of functions lacking a closed form antiderivative, which is therefore a task that can only be solved by numerical methods. We propose a new family of probability densities that can be used as substitutes and have the property of...

There is strong empirical evidence that the pricing kernel is Ushaped,which provides a way to explain the substantial coskewnesspremium. Existing studies typically use a polynomial approximationof the pricing kernel. Problematically, these polynomials have, inmost cases, increasing parts by...

Many statistical applications require an estimate of a covariance matrix and/or its inverse.When the matrix dimension is large compared to the sample size, which happensfrequently, the sample covariance matrix is known to perform poorly and may suffer fromill-conditioning. There already exists...
