John Cassidy, writing for The New Yorker: With the new school year starting, there is good news for incoming students of economics -- and anybody else who wants to learn about issues like inequality, globalization, and the most efficient ways to tackle climate change. A group of economists from both sides of the Atlantic, part of a project called CORE Econ, has put together a new introductory economics curriculum, one that is modern, comprehensive, and freely available online. In this country, many colleges encourage Econ 101 students to buy (or rent) expensive textbooks, which can cost up to three hundred dollars, or even more for some hardcover editions. The project is a collaborative effort that emerged after the world financial crisis of 2008-9, and the ensuing Great Recession, when many students (and teachers) complained that existing textbooks didn't do a good job of explaining what was happening. In many countries, groups of students demanded an overhaul in how economics was taught, with less emphasis on free-market doctrines and more emphasis on real-world problems.
