Leadership scholars are faced with pressing methodological issues that challenge our current scholarship. In this paper, we discuss methodological concerns such as multilevel hypothesis testing, construct validity of group-level scales, sampling countries in cross-cultural research, self-report...

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the...

We develop tests for structural breaks of factor loadings in dynamic factor models. We focus on the joint null hypothesis that all factor loadings are constant over time. Because the number of factor loading parameters goes to infinity as the sample size grows, conventional tests cannot be used....
