Annotation This is Vol 3 of the Handbook of Industrial Organization series (HIO). Vols 1 & 2 published simultaneously in 1989 under the editorship of Richard Schmalensee and Robert Willig. Many of the chapters in these successful volumes were widely cited and appeared on graduate reading lists, and some continue to appear even recently. Since the first volumes published, the field of industrial organization has continued to evolve. As the editors acknowledge in the Preface, these volumes had some gaps and this new volume aims to fill some of those gaps. The aim is to serve as a source, reference and teaching supplement for industrial organization, or industrial economics, the microeconomics field that focuses on business behavior and its implications for both market structures and processes, and for related public policies. The first two volumes of the HIO appeared at roughly the same time as Jean Tirole's book The Theory of Industrial Organization. Together they helped revolutionize the teaching of industrial organization, and provided a state-of-the-art summary. Tirole's book is concerned with the relevant theory, and several reviewers noted that the first two volumes of HIO contained much more discussion of the theoretical literature than of the empirical literature. In most respects, this imbalance was an accurate reflection of the field. Since then, the empirical literature has flourished, while the theoretical literature has continued to grow, and this new volume reflects that change of emphasis. *Part of the renown Handbooks in Economics series *Chapters are contributed by some of the leading experts in their fields. *A source, reference and teaching supplement for industrial organizations, or industrial economicists.

Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

While particularly dynamic and innovative, the digital and telecommunication industries are found to have a great tendency towards concentration, resulting in strong market power and raising concerns from competition and regulatory authorities. In this study focusing on such network industries, Jean-Marc Zogheib explores the interplay between public policy and firms' strategies by combining various tools of theoretical economic analysis adopted from industrial economics, network economics, and platform economics. Mr. Zogheib's thesis consists of three distinct essays: the first chapter examines how merger policy affects firms' entry strategies, the second chapter shifts the focus to public intervention by considering how the coexistence of private and public players affects competition and investment, while the third chapter investigates the role of privacy in competition between digital platforms and the importance of consumer data in the competitive analysis of mergers. This book clearly illustrates how economics can contribute essential building blocks to the construction of competitive reasoning and how the integration of competition law into economic models extended their collective utility. An important read for lawyers and economists alike. The book was awarded the inaugural Concurrences PhD Award in Economics.
