We consider the problem of testing whether the observations X1, · · ·, Xn of a time series are independent with unspecified (possibly nonidentical) distributions symmetric about a common known median. Various bounds on the distributions of serial correlation coefficients are proposed:...

In this paper, we test the international conditional CAPM model of Dumas and Solnik (1993) and the international conditional APT model of Ferson and Harvey (1992), as well as various extensions of these models. These models were typically estimated by GMM and found to be valid according to the...

The method of moments proposed by Carrasco and Florens (2000) permits to fully exploit the information contained in the characteristic function and yields an estimator which is asymptotically as efficient as the maximum likelihood estimator. However, this estimation procedure depends on a...
