The Assumptions Economists Make

Economists make confident assertions in op-ed columns and on cable news—so why are their explanations often at odds with equally confident assertions from other economists? And why are all economic predictions so rarely borne out? Harnessing his frustration with these contradictions, Jonathan Schlefer set out to investigate how economists arrive at their opinions. “A lucid, plain-spoken account of the major economic models, which [Schlefer] introduces in chronological order, creating a kind of intellectual history of macroeconomics. He explains what the models assume, what they actually demonstrate—and where they fall short.” —Binyamin Applebaum, New York Times blog “Fascinating...[Schlefer’s] book is a tough critique of economics, but a deeply informed and sympathetic one.” —Justin Fox, Harvard Business Review blog “This book is an impressive and informative analysis of the economics literature—and it presents some useful insights about how a more eclectic, catholic approach might allow economics to progress more convincingly into the future.” —Michelle Baddeley, Times Higher Education “The Assumptions Economists make [is] a knowledgeable...broadside against neoclassical economics...Schlefer’s gripes concern model-building run amok...His criticisms of these models are original and sophisticated.” —Christopher Caldwell, Literary Review

In April 2007, a report produced by the International Monetary Fund concluded that the world economy was in great shape only for the biggest economic crisis since the Great Depression to hit just months later. How could economists have got it so wrong? When engineers try to understand complex systems, they are forced to make simplifying assumptions. Sadly if these are flawed, no amount of mathematical wizardry will repair the damage. This book examines the possibility that the problem with economics stems from flawed assumptions. It appears that mainstream economics set off on the wrong foot.This book uncovers many such flaws and shows how the resulting bad economic theories have devastating consequences.Dr Michael Reiss shows how, with more realistic assumptions, economics, and our economic system, can be rescued.

A leading economist trains a lens on his own discipline to uncover when it fails and when it works.

Demonstrates the importance of social norms to firms and markets through historical context and theoretical and empirical evidence.

How to interpret and evaluate economic forecasts and the uncertainties inherent in them.

In this book, David K. Levine questions the idea that behavioral economics is the answer to economic problems. He explores the successes and failures of contemporary economics both inside and outside the laboratory, and asks whether popular behavioral theories of psychological biases are solutions to the failures. The book not only provides an overview of popular behavioral theories and their history, but also gives the reader the tools for scrutinizing them.

In the graveyard of economic ideology, dead ideas still stalk the land. The recent financial crisis laid bare many of the assumptions behind market liberalism—the theory that market-based solutions are always best, regardless of the problem. For decades, their advocates dominated mainstream economics, and their influence created a system where an unthinking faith in markets led many to view speculative investments as fundamentally safe. The crisis seemed to have killed off these ideas, but they still live on in the minds of many—members of the public, commentators, politicians, economists, and even those charged with cleaning up the mess. In Zombie Economics, John Quiggin explains how these dead ideas still walk among us—and why we must find a way to kill them once and for all if we are to avoid an even bigger financial crisis in the future. Zombie Economics takes the reader through the origins, consequences, and implosion of a system of ideas whose time has come and gone. These beliefs—that deregulation had conquered the financial cycle, that markets were always the best judge of value, that policies designed to benefit the rich made everyone better off—brought us to the brink of disaster once before, and their persistent hold on many threatens to do so again. Because these ideas will never die unless there is an alternative, Zombie Economics also looks ahead at what could replace market liberalism, arguing that a simple return to traditional Keynesian economics and the politics of the welfare state will not be enough—either to kill dead ideas, or prevent future crises. In a new chapter, Quiggin brings the book up to date with a discussion of the re-emergence of pre-Keynesian ideas about austerity and balanced budgets as a response to recession.
