In a seminal 1972 paper, Robert M. May asked: "Will a Large Complex System Be Stable?" and argued that stability (of a broad class of random linear systems) decreases with increasing complexity, sparking a revolution in our understanding of ecosystem dynamics. Twenty-five years later, May,...

The importance of correct and clear decisions during a complex and difficult situation is very easy to understand, but not so easy to achieve. Especially in situations where decision-makers must decide under time pressure and uncertainty. For instance, typical crisis situations have such...

How did developing Asian economies perform with respect to tax revenue mobilization before and during the coronavirus disease (COVID-19) pandemic? An analysis of data from developing Asia suggests that both short-run and long-run tax buoyancies, a measure of how tax revenue responds to gross...
