In the event of an unanticipated disruption to normal life, universities tend to shift to an online environment in both delivery and assessment. Course instructors still need to assign grades despite not having the full set of planned assessments. This paper examines how grades are disrupted...

This paper demonstrates that unit root tests can suffer from inflated Type I error rates when data are cointegrated. Results from Monte Carlo simulations show that three commonly used unit root tests - the ADF, Phillips-Perron, and DF-GLS tests - frequently overreject the true null of a unit...

A meta-analysis (MA) aggregates estimated effects from many studies to calculate a single, overall effect. There is no one, generally accepted procedure for how to do this. Several estimators are commonly used, though little is known about their relative performance. A complication arises when...
