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 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 …

In this note we propose a simple method of measuring directional predictability and testing for the hypothesis that a given time series has no directional predictability. The test is based on the correlogram of quantile hits. We provide the distribution theory needed to conduct inference,...

A semiparametric regression … responses are imputed using the semiparametric regression method the empirical log-likelihood is asymptotically a scaled chi … bootstrap empirical log-likelihood ratio is derived and its distribution is used to approximate that of the imputed empirical …

This paper develops methodology for nonparametric estimation of a polarization measure due to Anderson (2004) and Anderson, Ge, and Leo (2006) based on kernel estimation techniques. We give the asymptotic distribution theory of our estimator, which in some cases is nonstandard due to a boundary...
