Industrial Organization: Theory and Practice blends a rigorous theoretical introduction to industrial organization with empirical evidence, real-world applications, and case studies. It also supports students with a range of theoretical and applied problems and exercises. This balanced approach has earned the book its place as one of the leading undergraduate texts on industrial organization. The sixth edition has significantly expanded and updated theories, empirical findings, applications, industry landscapes, policies, and cases throughout the book to reflect the latest developments in the field. Major updates include: additional theoretical concepts (with applications) addressing current trends in business practices, such as platform markets, algorithmic pricing, monopsony, killer acquisitions, subcontracting, subscription plans, influencer marketing, and network effects; recent developments in public policy toward Big Tech and dominant platforms, labor market concentration, algorithmic collusion, and net neutrality; greater emphasis on global perspective with a broader range of international examples, applications, and cases; enhanced coverage of empirical approaches in industrial organization, including an introduction to discrete choice models and difference-in-differences methods; a supplementary digital resource package, offering additional learning and teaching materials. This comprehensive book bridges the gap between economic theory and real-world case studies in an accessible, logical manner, making it the ideal undergraduate text for courses on industrial organization.
