The concept of information efficiency is central to many studies of financial markets, and these studies have been well surveyed to date. A betting market is an example of a simple financial market, but one which offers researchers the added advantage that it is characterized by a well‐defined termination point at which each asset (or bet) possesses a definite value. In consequence, it is much more convenient to use this particular context to formulate tests of information efficiency, and from these tests to draw useful conclusions. This paper surveys the rapidly growing literature which has to date addressed this issue of information efficiency in betting markets.

This textbook introduces students to the sub-field of critical security studies through a detailed yet accessible survey of emerging theories and practices. This 3rd edition contains two new chapters - on 'Ontological Security' and '(In)Security and the everyday' - and has been fully revised and updated. Written in an accessible and clear manner, Critical Security Studies: offers a comprehensive and up-to-date introduction to critical security studies locates critical security studies within the broader context of social and political theory evaluates fundamental theoretical positions in critical security studies against backdrop of new security challenges. The book is divided into two main parts. Part I, 'Approaches', surveys the newly extended and contested theoretical terrain of critical security studies: Constructivist theories, Critical Theory, Feminist and gender approaches, Postcolonial perspectives, Poststructuralism and International Political Sociology, Ontological security, and Securitisation theory. Part II, 'Issues', examines how these various theoretical approaches have been put to work in critical considerations of environmental and planetary security, health, human security and development, technology and warfare, migration and border security, (in)security and the everyday, and terror, risk and resilience. The historical and geographical scope of the book is deliberately broad and each of the chapters in Part II concretely illustrates one or more of the approaches discussed in Part I, with clear internal referencing allowing the text to act as a holistic learning tool for students.

"European-East Asian Borders is an international, trans-disciplinary volume that breaks new ground in the study of borders and bordering practices in global politics. It explores the insights and limitations of border theory developed primarily in the European context to a range of historical and contemporary border-related issues and phenomena in East Asia. The essays presented here question, rather than assume, the various borders between inclusion/exclusion, here/there, us/them, that condition the (im)possibility of translating between histories, cultures and identities. Contributors suggest that the act of translation offers new ways of thinking about how border logics operate, taking on the concept of translation itself as border problematic and therefore raising questions of power and authority, such as who gets to act as a translator, or who benefits from the outcome.The book will appeal not only to upper-level students and scholars with a geopolitical-historical interest in East Asia, but also to those who work in the inter-disciplinary field of border studies and others with an interest more generally in translation and the extent to which theory 'travels' across time and space"--
