This book focuses on four types of mission composition--diversity among peacekeepers, within the mission leadership, between mission leaders and peacekeepers, and between peacekeepers and locals.

We provide novel empirical models of the arms trade and focus on the role of energy dependence, in particular of oil, in explaining the trade of weapons between countries.

We explore the geo-strategic determinants of bilateral trade flows between the USA and the rest of the world.

Abstract: Terrorists aim at influencing audiences beyond their immediate victims, but can only achieve this if an attack receives sufficient public attention.

We explore how institutional set-ups, in particular changes in political institutions through coups d'état, can affect the way military expenditures are determined.

Numerous studies demonstrate that terrorism causes strong public reactions immediately after the attack, with important implications for democratic institutions and individual well-being.

Public opinion in favor of regional unification is usually seen as key for successfully implementing such integration projects.

This book explores diversity in the composition of peace missions (in terms of peacekeepers' nationalities, linguistic, and religious differences deployed) and theorizes about the impact of mission composition on peacekeeping effectiveness.
