Firewall? or Wall on Fire? A Unified Framework of Conflict Contagion and the Role of Ethnic Exclusion

Abstract

While some borders are real firewalls against conflicts, others appear like tinder just waiting for the smallest spark. Only recently has research focused on the transnational perspective of conflict and current research has focused mostly on isolated aspects of this phenomenon. In this article, we provide a unified framework for conflict contagion that takes into account receiver, sender, dyad, and network effects. This is a novel perspective on conflict contagion, and our empirical results suggest that distinguishing between sender and receiver effects allows for a better understanding of spillover effects. We provide insights that especially excluded ethnic groups impact the risk of countries sending and receiving conflicts from its neighbors.
