This paper investigates the causal relations between stock return and volume based on quantile regressions. We first define Granger non-causality in all quantiles and propose testing non-causality by a sup-Wald test. Such a test is consistent against any deviation from non-causality in...

We propose an encompassing test for non-nested linear quantile regression models and show that it has an asymptotic [chi]2 distribution. It is also shown that the proposed test is a regression rank score test in a comprehensive model under conditional homogeneity. Our simulation results indicate...

This paper devises a methodology to compare the accuracy of prediction markets and polls. The data of the Exchange of Future Events (xFuture) for Taiwan’s 2006 mayoral elections and 2008 presidential election show that the prediction markets outperform the opinion polls in various indices of...

This paper applies the dynamic panel quantile regression (DPQR) model under the autoregressive distributional lag (ARDL) specification, and examines the deficit–inflation relationship in 91 countries from 1960 to 2006. The DPQR model estimates the impact of deficits on inflation at various...
