Agency, Structure and International Politics [PDF ebook] 
From Ontology to Empirical Inquiry

The concepts of agency and structure are of increasing and defining importance to international relations and politics as fields of enquiry and knowledge. This is the first book to explore the two concepts in depth in that context.The agent-structure problem refers to questions concerning the interrelationship of agency and structure, and to the ways in which explanations of social phenomena integrate and account for them. This is an important contribution to the study of international relations and politics.
