A New Way to Learn Economics


John Cassidy in The New Yorker:

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 morefor some hardcover editions. The core curriculum includes a lengthy e-book titled “The Economy,” lecture slides, and quizzes to test understanding. Some of the material has already been used successfully at colleges like University College London and Sciences Po, in Paris.

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.

Traditional, wallet-busting introductory textbooks do cover topics like pollution, rising inequality, and speculative busts. But in many cases this material comes after lengthy explanations of more traditional topics: supply-and-demand curves, consumer preferences, the theory of the firm, gains from trade, and the efficiency properties of atomized, competitive markets. In his highly popular “Principles of Economics,” Harvard’s N. Gregory Mankiw begins by listing a set of ten basic principles, which include “Rational people think at the margin,” “Trade can make everybody better off,” and “Markets are usually a good way to organize economic activity.”

The core approach isn’t particularly radical. (Students looking for expositions of Marxian economics or Modern Monetary Theory will have to look elsewhere.) But it treats perfectly competitive markets as special cases rather than the norm, trying to incorporate from the very beginning the progress economists have made during the past forty years or so in analyzing more complex situations: when firms have some monopoly power; people aren’t fully rational; a lot of key information is privately held; and the gains generated by trade, innovation, and finance are distributed very unevenly. The corecurriculum also takes economic history seriously.
