Take Me Home, Country Roads: Historical Diasporas and Contemporary FDI Patterns

open access: yesThe World Economy, Volume 49, Issue 1, Page 94-117, January 2026.

Abstract We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To investigate temporal differences of multi‐elves, we analyzed data from four storms occurring at various times and distances from the Pierre Auger Observatory in ...
