Title overview

Economics is a living discipline, changing and evolving in response to developments in the world economy and in response to the research of many thousands of economists throughout the world. Through eighteen editions, this resource has evolved with the discipline. Our purpose in this edition, as in the previous seventeen, is to provide students with an introduction to the major issues facing the world’s economies, to the methods that economists use to study those issues, and to the policy problems that those issues create.

Hallmark features of this title

  • Current. Economic growth, financial crisis pandemics, globalization, and the role of government are pressing issues of the day. Much of our study of economic principles and the Canadian economy has been shaped by these issues. In addition to specific coverage of growth and internationally oriented topics, growth and globalization appear naturally throughout the book in the treatment of many topics once thought to be entirely “domestic.”
  • Global. Enormous changes have occurred throughout the world over the last few decades. Flows of trade and investment between countries have risen so dramatically that it is now common to speak of the “globalization” of the world economy. Today it is no longer possible to study any economy without taking into account developments in the rest of the world.
  • Free Markets. Has the fundamental role of government changed significantly over the past 40 years? In order to understand the role of government in the economy, students must understand the benefits of free markets as well as the situations that cause markets to fail. They must also understand that governments often intervene in the economy for reasons related more to equity than to efficiency.

GenAI Study Tool

We’ve heard how important it is for students to use reliable AI tools in responsible and productive ways. To that end, Pearson is focused on creating tools that combine the power of generative AI with trusted Pearson content to provide students with a simplified study experience, delivering on-demand and personalised support that compliments your teaching and aligns with the text you’ve chosen. The Study Tool is available to students who access the Pearson eText on its own or through MyLab.

What can the AI Study Tool do?

  • Generate simplified explanations of challenging sections
  • Summarize material to help learners focus on key topics and ideas
  • Students can ask for multiple choice or short answer questions related to a specific chapter or section to help fill knowledge gaps
  • For extra practice, students can also generate flashcards and notes based on their chat interaction with the tool

New and updated features of this title

  • Part 1: What Is Economics? In Chapter 1, we have added two new “hot” topics in the chapter opener: rising housing prices and the challenge of Indigenous Reconciliation. We have also added a few paragraphs early in the chapter to clarify how we will use the terms of “advanced” and “developing” economies throughout the textbook. In the discussion of scarcity, we have added an example of the problem of growing scarcity of water, and this leads to a new “Policy Briefing” podcast—the first topic in a new collection of podcasts examining a range of contentious policy issues.
  • Part 4: The Economy in the Long Run. In Chapter 9 on the macroeconomic adjustment process, we have clarified the explanation of the Y* locus and have removed the detailed empirical discussion and graph of the Canadian Phillips Curve. This discussion proved to be too complicated for an introductory textbook. We have also clarified the discussion of automatic fiscal stabilizers. Our discussion of fiscal policy now leads to a Policy Briefing podcast that addresses the issue of whether government spending can “create jobs,” and under what conditions.
  • Part 5: Money, Banking, and Monetary Policy. Chapter 13 provides a detailed discussion of Canadian monetary policy. When discussing how the Bank of Canada targets the overnight interest rate, we have modified our treatment to incorporate recent changes in the Bank’s policy, whereby it pays interest on reserves at the overnight rate and charges the bank rate on any loans to commercial banks. The “target range” is now only 0.25 basis points wide, with a floor at the target for the overnight rate.
  • Part 6: Macroeconomic Problems and Policies. Chapter 14 examines inflation and disinflation in detail.While there have been no major changes in the structure of this chapter, the inflation that we witnessed in the immediate post-pandemic period is reflected in the discussion. In our final discussion of the costs of reducing inflation, we direct the reader to a Policy Briefing podcast on the age-old debate over the benefits of reducing inflation versus the (temporary) costs of raising unemployment.

Key features

Digital Assets

  • GenAI Study Tool. We’ve heard how important it is for students to use reliable AI tools in responsible and productive ways. To that end, Pearson is focused on creating tools that combine the power of generative AI with trusted Pearson content to provide students with a simplified study experience, delivering on-demand and personalised support that compliments your teaching and aligns with the text you’ve chosen.
  • Dynamic Study Modules. Using a highly personalized, algorithmically driven process, Dynamic Study Modules continuously assess student performance and provide additional practice in the areas where they struggle the most. Each Dynamic Study Module, accessed by computer, smartphone, or tablet, promotes fast learning and long term retention.
  • Author Videos. Our author, Chris Ragan, is featured in our new part opening videos. The videos act as an introduction to the concepts that will be covered in the upcoming chapters of the text. Chris also brings his thoughts and insights into how to succeed in your economics course and makes connections to how these economic principles are relevant in your life and future career. The videos appear in the eTextbook and can be assigned through the multimedia library of MyLab.
  • Solved Problem Videos. Many students have difficulty handling economics problems. We help students overcome this hurdle by including new Solved Problem Videos where Chris Ragan gives them a model for how to solve an economic problem by breaking it down step by step.
  • Policy Briefing Podcasts. Author Chris Ragan has created an engaging new “Policy Briefing” podcast series that dives into the dynamic world of contemporary economic policies. Embedded within the eTexbook and assignable via the MyLab, the episodes explore some of the most pressing economic issues of our time, presenting both sides of the debate to help students in principles of economics courses understand the complexities and nuances of each topic. These thought-provoking discussions are designed to pique students’ interest and deepen their understanding of the economic policies shaping our world.
  • Single Player Experiments. Experiments are an easy-to-use, fun, and engaging way to promote active learning and mastery of important economic concepts. Single-player experiments allow students to play against virtual players from anywhere at any time so long as they have an Internet connection. Pre- and post-experiment questions are available for assignment within the MyLab.
  • Digital Interactives. Economic principles are not static ideas, and learning them shouldn't be either. Digital Interactives are dynamic and engaging assessment activities that promote critical thinking and application of key economic principles. Each Digital Interactive has 3–5 progressive levels and requires approximately 20 minutes to explore, apply, compare, and analyze each topic. Digital Interactives can be assigned and graded within MyLab Economics or used as a lecture tool to encourage engagement, classroom conversation, and group work.
  • GeoGebra Graphing Questions. These gradable graphing exercises help students demonstrate their understanding. Assignable alongside our MyLab homework exercises, they enable students to interact directly with the graph in a manner that reflects how students would graph on paper.
  • Learning Catalytics. Learning Catalytics™ allows students to use any webenabled device to participate in class. Instructors can access a library of pre-built questions or construct questions on their own to keep students engaged in the lecture. Learning Catalytics can be assigned to students synchronously or asynchronously and used for individual or group work. It can also place students in discussion groups based on their responses and location, regardless of class size.
  • Translation Support. The new text translation tool provided in Pearson eTextbooks lets your students see on-screen translations of any word or section in the text. Available to support over 100 different languages, this innovative translation tool can reduce the risk of students’ comprehension being lost in translation - increasing their chances of success and ensuring greater inclusivity.
