We provide a test of the Monday effect in daily stock index returns. Unlike previous studies we define the Monday effect based on the stochastic dominance criterion. This is a stronger criterion than those based on comparing means used in previous work and has a well defined economic meaning. We...

We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap … or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that … the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have …

We investigate the use of subsampling for conducting inference about the quadratic variation of a discretely observed … diffusion process under an infill asymptotic scheme. We show that the usual subsampling method of Politis and Romano (1994) is … inconsistent when applied to our inference question. Recently, a type of subsampling has been used to do an additive bias …
