Jay Prag – författare

The new edition of a concise and nontechnical but rigorous introductory text that emphasizes fundamental concepts and real-world applications, thoroughly revised and updated.

This introductory text offers an alternative to the encyclopedic, technically oriented approach taken by traditional textbooks on macroeconomic principles. Concise and nontechnical but rigorous, its goal is not to teach students to shift curves on diagrams but to help them understand fundamental macroeconomic concepts and their real-world applications. It accomplishes this by providing a clear exposition of introductory macroeconomic theory along with more than 700 one- or two-sentence “news clips,” based on economics media coverage, as illustrations or student exercises. Although the writing is accessible, end-of-chapter questions are challenging, requiring a thorough understanding of related macroeconomic concepts, critical-thinking skills, and an ability to make connections to the real world.

This fourth edition has been thoroughly revised and updated, with new material on such topics as aggregate supply and demand, supply-side models, recent issues faced by the Federal Reserve, the role of government, and “burst bubbles.” The more challenging end-of-chapter questions are separated out, and news clip questions have been added that refer to recent events. Optional chapter appendixes offer technical material; other appendixes provide answers to sample exam questions and to even-numbered end-of-chapter questions. Text boxes (“curiosities”) offer short expositions of related topics. The book can be used as a text for principles of macroeconomics and applied macroeconomics courses, as a supplementary text for a traditional macro-principles course, or for MBA macroeconomics courses.

This concise and nontechnical introduction to microeconomics emphasizes concepts over mathematics. Keeping in mind that sometimes the most accurate model is not very useful in the real world, Microeconomic Essentials balances economics as mathematics with economics as a social process. Microeconomics is part of daily life; gas prices, wage increases, the rising cost of health care, international trade: all are microeconomic topics. Therefore, like its predecessor, Macroeconomic Essentials, this textbook accompanies its explanations with examples and real-world applications.

The book covers the basic market model of supply and demand, showing how this “powerhouse” model can explain most price changes in the market. It discusses government intervention in the market; consumer theory and utility maximization, considering both concepts and real-world issues; the theory of the firm, “de-mathematizing” marginal revenue, marginal cost, and other topics; monopolies; perfect competition; and imperfect competition and oligopolies, as illustrated by OPEC, Coke, and Pepsi. It discusses game theory, reviewing the familiar models and concepts—while cautioning that game theory is best thought of as “a state of mind”; input markets; welfare and public economics, applying the tools presented in previous chapters; and international trade. Each chapter ends with examples and exercises. Appendixes supply answers to sample exam questions and solutions to even-numbered exercises.

Useful Game Theory offers a refreshing perspective on modern wisdom, empowering readers to master strategic decision-making with the tools they already possess.

Every decision you make involves an element of game theory, often without you even realizing it. In this insightful book, economist Jay Prag and marketing strategist Amanda Ishak Prag delve into the essence of human nature, transforming the mathematical principles of game theory into practical, everyday strategies. Through familiar proverbs and timeless wisdom, readers will explore how elements like reputation, biases, cooperation, and family dynamics influence our strategic interactions.

From navigating a four-way stop and choosing take-out dinners to understanding the complexities of nuclear disarmament, Useful Game Theory demonstrates how recognizing the structure of games—players, choices, and outcomes—can enhance decision-making in all aspects of life.
