Principles of
Economics,
13th Edition
Karl E. Case, Wellesley College
Ray C. Fair, Yale University
Sharon E. Oster, Yale University
Reviewers tell us that Case, Fair, and Oster’s Principles of Economics is one of the all-time bestselling
principles of economics texts because they trust it to be clear, thorough and complete. Readers come
away with a basic understanding of how market economies function, an appreciation for the things
they do well, and a sense of things they do poorly.
The 13th Edition features the latest research and new exercises. Students begin to learn the art
and science of economic thinking and start to look at some policy, and even personal decisions, in a
different way.
New and Updated Features
› More thorough discussion of important topics
and issue has been added.
› Different research methodologies of
economics are further examined, giving students
a sense of what these methodologies are and
how to apply them.
› End-of-Chapter Critical-Thinking Questions
and Problems reinforce principles and give
students the opportunity to practice what they’ve
just learned.
› Real-world examples and applications illustrate
and reinforce key economic concepts.
› Economics in Practice boxes focus on recent
research and events that support key chapter
concepts.
Hallmark Features
› A 3-tiered explanation of key concepts uses
intuitive stories, tables, graphs and equations
to present concepts with a mathematical
formula. This lets instructors effectively cover
large amounts of material and helps students
understand it.
–C
oncept Checks act as speed bumps that
encourage students to stop and check their
understanding of fundamental terms and
concepts before moving on.
› Keynesian Cross material is integrated
throughout the text and builds up to the AD/
AS model. This way, students won’t mistakenly
apply what they’ve learned about simple
demand and supply to aggregate demand
and supply.
