This provides the basis for a modern treatment of markets including price-making as well as price-taking, the exercise of power, and the importance of social norms and adjustment to disequilibria.Introducing labour and credit markets with incomplete contracts allows a consistent treatment of aggregate employment and fluctuations without the need for ad hoc sticky price and wage assumptions. Banks create money by extending credit and a central bank seeks to implement a target inflation rate.Growth and instability are illustrated from the Great Depression, through the post-war golden age of capitalism through to the financial crisis and ensuing uncertainties. Students acquire an understanding of the past and current evolution of the economy in its social and environmental context, equipping them to marshal evidence and articulate positions about contemporary policy issues.Key Features of this Edition:Economist in Action videos by Al Roth, James Heckman, Thomas Piketty, and others give students a glimpse of what economists do and how they engage in real policy questionsHow economists learn from facts boxes introduce students to research practice including how to identify causation using experiments and other methodsWhen economists disagree features engage the student with evidence and controversiesThe Read more suggestions direct the reader to resources they can consult to take their learning furtherStudent-paced interactive diagrams suited to diverse learner capabilities are available within the CORE open access ebook available here - www.core-econ.orgMultiple-choice questions (with explanations of correct and incorrect answers) allow students to self-test their understandingGreat Economists panels showcase a range of influential thinkers who have shaped the path of economicsDefinitions explain important terms right where neededEinsteins provide an opportunity for readers to explore the quantitative aspects of the topics under discussion in more detailOnline Leibniz calculus supplements provide a calculus-based course option, enhancing flexibility of use.
