Revised and updated for the second edition, this textbook presents over 100 exercises on industrial organization with detailed answer keys. While most textbooks on industrial organization focus on theory and empirical findings, this textbook offers practical examples and exercises helping predict firm behavior in different industries. The book emphasizes the game-theoretic tools used in each type of exercise, so students can systematically apply them to other markets, forms of competition, or information environments where firms, consumers, and regulating agencies interact. The book begins with examples that analyze different models of firm behavior and interaction; starting with monopoly and moving through the Cournot model of simultaneous quantity competition, the Bertrand model simultaneous price competition, and sequential competition. The following chapters apply game-theoretic tools to situations of increasing complexity: regulation; R&D incentives; mergers and collusion; bundling incentives; incomplete information, signaling, and competition; networks and switching costs. In addition to providing algebraic simplifications, some chapters also offer the unique feature of worked exercises based on published journal articles by leading scholars in the field. Finally, exercises are ranked according to their difficulty, with a letter (A-C) next to the exercise number, which allows students to pace their studies and instructors to structure their classes accordingly. The second edition contains additional exercises optimized for study at the upper undergraduate level. Providing a rigorous, yet practical introduction to the field of industrial organization, this textbook is appropriate for advanced undergraduate and graduate students in economics and finance.

The emergence over the last 10 years of the analytic concept, 'Translanguaging', has had a forceful impact on the field of Applied Linguistics. This book addresses how it has contributed to our understandings of language, bilingualism and education. Ofelia Garcia and Li Wei trace the development of the theory of Translanguaging and consider its relationship with traditional theories and models of language and bilingualism. Based on practices by students and teachers in a variety of educational contexts, this book describes how Translanguaging is used by bilingual learners to learn and by teachers to teach. Ultimately, the book affirms the transformative nature of Translanguaging; it involves the act of languaging between and beyond systems that have previously been described as separate, and in so doing, new meanings emerge and new understandings are generated, transforming not only semiotic systems and speaker subjectivities, but also social structures.
