Introducing PEIG 2.0: Sixty-nine years of partisan electoral interventions 1946–2014

Abstract

In this article we introduce an updated version of the Partisan Electoral Intervention by Great-powers (PEIG) dataset, which collects data on situations where a foreign power tries to determine the election results in another country. This version expands the temporal coverage of PEIG into much of the Post-Cold War era and checks for possible unconfirmed or undetected cases in the period covered by PEIG 1.0, leading to an expanded PEIG 2.0 dataset with a 25.5% increase in temporal coverage and a 37.4% increase in the overall number of electoral intervention cases. After describing the PEIG dataset update process, we describe the patterns of electoral interventions in the Post-Cold War era in comparison with the Cold War era. We then examine the possibility of shifts in their effects in the Post-Cold War era by replicating one key result using the previous version of PEIG, finding no such effect.
