OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Weaponized Interdependence: Global Monopolies as the Sources of Power
This paper focuses on the weaponization of interdependences among states. Weaponization refers to one state restricting its international economic relationships (or ‘interdependences’) to inflict economic or political costs on another state. Recent examples include Western sanctions against Russia over Ukraine and Russia’s retaliatory restriction of gas supplies to several European states. We know surprisingly little about two related questions: what determines whether a particular international economic relationship can be weaponized effectively? Why are some states better positioned than others to weaponize their international economic relationships? This gap is unfortunate considering the high stakes policymakers increasingly face when deciding which international economic relationships to encourage and which to cut to prevent becoming subjects of economic coercion. This paper argues that only monopolistic international economic relationships—which a state cannot substitute easily—can be weaponized effectively. States can weaponize the supply and demand side of international economic relationships. Network effects, technological advantages, transaction costs, and natural resources are frequent sources of supply-side monopoly power. On the demand side, the sender’s demand size, the target’s cost structure, the good or service’s differentiation, and transaction costs are important determinants of monopoly power.
