One of the dangers of high inflation is that it can cause firms and households to pay close attention to it. This internalization of inflation can lead to an accelerationist regime, making inflation harder to control. We empirically assess the relationship between attention and the level of...

Water pollution is one of the most significant environmental problems nowadays. The remediation of oxyanion pollutions is of critical concern due to their recalcitrance and persistence in the environment as well as acute toxicities even at trace concentration levels. In this study, a water...

<?Pub Caret> Design weights in surveys are often adjusted to accommodate auxiliary information and to meet pre-specified range restrictions, typically via some ad hoc algorithmic adjustment to a generalised regression estimator. In this paper, we present a simple solution to this problem using empirical...</?pub>

Modern random matrix theory indicates that when the population size p is not negligible with respect to the sample size n, the sample covariance matrices demonstrate significant deviations from the population covariance matrices. In order to recover the characteristics of the population...
