Meta-analytic panel unit root tests such as Fisher’s χ2 test, which consist of pooling the p-values of time series unit root tests, are widely applied in practice. Recently, several Monte Carlo studies have found these tests’ Error-in-Rejection Probabilities (or, synonymously, size distortion) to increase with the number of series in the panel. We investigate this puzzling finding by modelling ...

The class of 2K2-free graphs and its various subclasses have been studied in a variety of contexts. In this paper, we are concerned with the colouring of (P3 ∪P2)-free graphs, a super class of 2K2-free graphs. We derive a O(ω3) upper bound for the chromatic number of (P3 ∪P2)-free graphs, and sharper bounds for (P3 ∪P2, diamond)-free graphs, where ω denotes the clique number. By applying simila...
