Book Description
Anderson, Goeree and Ramer (1997) observe that although the Uniform consumer density is almost universally assumed in Hotelling style location games, it is more realistic to assume non-uniform distributions. Using Anderson et al.'s (1997) sufficient conditions for the existence of a unique pure strategy equilibrium, we extend the list of known distributions with characterised equilibria from two (Uniform and Triangular) to seven. Our extension includes the Normal and Logistic distributions which are commonly used in empirical research. We also analyse the effects of density choice on equilibrium outcomes. Holding the mean and dispersion of consumer tastes constant, we find that the Uniform distribution inflates differentiation effects.

Book Description
These proceedings are from a conference held at the Centre for Regional Science (CERUM) at Umea Umeâ University, Sweden, 17-18 June 2001. Unlike Un1ike many conference proceedings, this volume contains only on1y invited invited contribu contribu tions tions on specified topics so as to make the book coherent and self-contained. The authors and editors hope that this coherence will make the volume use fu1 fuI also as a text for courses in industrial organisation. To this end two chap ters on the history of oligopoly theory, from the beginnings with Cournot 1838, to the present day, and one chapter on modem methods for analysing iterated discrete time maps, have been inserted at the beginning ofthe book. Unlike Un1ike most current literature on games and oligopoly, this book is not focused on the usual topics of game theory: optimal strategies, dominance, and equilibrium. Rather it is the evolutionary dynamics, often of a complex type, inc1uding deterministic chaos, which are in focus. The contributions, after the historical and the methodological introductions, represent various segments of the research frontier in this area, though pains have been taken to tie some of the models to a number of most promising contributions from the frugal period 1929-1941, which have suffered from unjust neglect in the following industrial organisation literature.

Book Description
In this critical primer, Michael Z. Newman introduces newcomers to the key concepts, issues, and vocabulary of media studies. Across ten chapters, Newman examines topics from text and audience to citizenship and consumerism, drawing on a myriad of examples of media old and new. Film and TV rub shoulders with mobile games and social media, and popular music and video sharing platforms with journalism and search engines. While the book takes a critical, cultural approach, it covers topics that apply across many kinds of media scholarship, bridging the humanities and the social sciences and looking at media as a global phenomenon. It considers media in relation to society and its unequal structures of power, and relates media representations to their conditions of production in media industries and consumption in the everyday lives of audiences and users. Spanning the historical periods of mass media and online participatory culture, it also probes assumptions about media that were formulated in a previous era and looks at how to update our thinking to address an ever-changing digital mediascape. With its clear and accessible style, this book is tailor-made for undergraduate students of media, communication, and cultural studies, as well as anyone who would like to better understand media.

Book Description
Leading political innovation activist Katherine Gehl and world-renowned business strategist Michael Porter bring fresh perspective, deep scholarship, and a real and actionable solution, Final Five Voting, to the grand challenge of our broken political and democratic system. Final Five Voting has already been adopted in Alaska and is being advanced in states across the country. The truth is, the American political system is working exactly how it is designed to work, and it isn't designed or optimized today to work for us—for ordinary citizens. Most people believe that our political system is a public institution with high-minded principles and impartial rules derived from the Constitution. In reality, it has become a private industry dominated by a textbook duopoly—the Democrats and the Republicans—and plagued and perverted by unhealthy competition between the players. Tragically, it has therefore become incapable of delivering solutions to America's key economic and social challenges. In fact, there's virtually no connection between our political leaders solving problems and getting reelected. In The Politics Industry, business leader and path-breaking political innovator Katherine Gehl and world-renowned business strategist Michael Porter take a radical new approach. They ingeniously apply the tools of business analysis—and Porter's distinctive Five Forces framework—to show how the political system functions just as every other competitive industry does, and how the duopoly has led to the devastating outcomes we see today. Using this competition lens, Gehl and Porter identify the most powerful lever for change—a strategy comprised of a clear set of choices in two key areas: how our elections work and how we make our laws. Their bracing assessment and practical recommendations cut through the endless debate about various proposed fixes, such as term limits and campaign finance reform. The result: true political innovation. The Politics Industry is an original and completely nonpartisan guide that will open your eyes to the true dynamics and profound challenges of the American political system and provide real solutions for reshaping the system for the benefit of all.

Book Description
James Friedman provides a thorough survey of oligopoly theory using numerical examples and careful verbal explanations to make the ideas clear and accessible. While the earlier ideas of Cournot, Hotelling, and Chamberlin are presented, the larger part of the book is devoted to the modern work on oligopoly that has resulted from the application of dynamic techniques and game theory to this area of economics. The book begins with static oligopoly theory. Cournot's model and its more recent elaborations are covered in the first substantive chapter. Then the Chamberlinian analysis of product differentiation, spatial competition, and characteristics space is set out. The subsequent chapters on modern work deal with reaction functions, advertising, oligopoly with capital, entry, and oligopoly using noncooperative game theory. A large bibliography is provided.

Book Description
The uneven geographical distribution of economic activities is a huge challenge worldwide and also for the European Union. In Krugman’s New Economic Geography economic systems have a simple spatial structure. This book shows that more sophisticated models should visualise the EU as an evolving trade network with a specific topology and different aggregation levels. At the highest level, economic geography models give a bird eye’s view of spatial dynamics. At a medium level, institutions shape the economy and the structure of (financial and labour) markets. At the lowest level, individual decisions interact with the economic, social and institutional environment; the focus is on firms’ decision on location and innovation. Such multilevel models exhibit complex dynamic patterns – path dependence, cumulative causation, hysteresis – on a network structure; and specific analytic tools are necessary for studying strategic interaction, heterogeneity and nonlinearities.

Book Description
A new paradigm for balancing flexibility and commitment in management strategy through the amalgamation of real options and game theory. Corporate managers who face both strategic uncertainty and market uncertainty confront a classic trade-off between commitment and flexibility. They can stake a claim by making a large capital investment today, influencing their rivals' behavior, or they can take a “wait and see” approach to avoid adverse market consequences tomorrow. In Competitive Strategy, Benoît Chevalier-Roignant and Lenos Trigeorgis describe an emerging paradigm that can quantify and balance commitment and flexibility, “option games,” by which the decision-making approaches of real options and game theory can be combined. The authors first discuss prerequisite concepts and tools from basic game theory, industrial organization, and real options analysis, and then present the new approach in discrete time and later in continuous time. Their presentation of continuous-time option games is the first systematic coverage of the topic and fills a significant gap in the existing literature. Competitive Strategy provides a rigorous yet pragmatic and intuitive approach to strategy formulation. It synthesizes research in the areas of strategy, economics, and finance in a way that is accessible to readers not necessarily expert in the various fields involved.
