Network Dynamics and Coercion in International Relations

When does coercion succeed in international relations? Why do states resist coercion in some cases but concede in others? This dissertation adopts network analysis to investigate the network factors influencing the success and failure of economic and military coercion. The first chapter addresses the coercion target states’ information problem regarding how coercers would react to the targets’ resistances and concessions. By regarding resistances and concessions as network ties that can transmit information, it argues that past coercion outcomes endogenously influence targets’ current responses and coercion outcomes. Specifically, target states are more likely to concede to coercers who have been successful in gaining others’ compliance. Sender states are more likely to succeed in coercion when they had successful coercion in the past. The second chapter adds a condition to the first chapter’s argument. It argues that when being coerced by the same sender, a stronger sanction target’s compliance is likely to prompt a weaker target’s acquiescence, and that a weaker target’s resistance is likely to prompt a stronger target’s resistance. The third chapter explores how states’ positions in international security and economic networks influence the success and failure of military and trade coercion. States that occupy different network positions own different network power. I argue that when the coercion sender has relatively more network power than the target, the more likely coercion will be successful. I use interstate military alliances and arms transfer data to operationalize international security networks. International economic networks are operationalized by bilateral trade and regional trade agreements networks. Using military and trade coercion outcomes in the Military Compellent Threats (MCT) and the Threats and Imposition of Economic Sanctions (TIES) datasets as outcome variables, the statistical analysis partially supports my argument. Trade coercion is more likely to succeed when the sender has more network power. However, military coercion is less likely to succeed when the sender has more network power than the target.
