Book Preface

Ten years ago we wrote a book about the work we do. To our surprise, it found an audience. We were flattered, but it was clear to us that we were done. Economists do not really write books, least of all books human beings can read. We did it and somehow got away with it; it was time to go back to what we normally do, which is to write and publish research papers.
Which is what we were doing while the dawn-light of the early Obama years gave way to the psychedelic madness of Brexit, the Yellow Vests, and the Wall—and strutting dictators (or their elected equivalents) replaced the confused optimism of the Arab Spring. Inequality is exploding, environmental catastrophes and global policy disasters loom, but we are left with little more than platitudes to confront them with.
We wrote this book to hold on to hope. To tell ourselves a story of what went wrong and why, but also as a reminder of all that has gone right. A book as much about the problems as about how our world can be put back together, as long as we are honest with the diagnosis. A book about where economic policy has failed, where ideology has blinded us, where we have missed the obvious, but also a book about where and why good economics is useful, especially in today’s world.
The fact that such a book needs to be written does not mean we are the right people to write it. Many of the issues plaguing the world right now are particularly salient in the rich North, whereas we have spent our lives studying poor people in poor countries. It was obvious that we would have to immerse ourselves in many new literatures, and there was always a chance we would miss something. It took us a while to convince ourselves it was even worth trying.
We eventually decided to take the plunge, partly because we got tired of watching at a distance while the public conversation about core economic issues—immigration, trade, growth, inequality, or the environment—goes more and more off-kilter. But also because, as we thought about it, we realized the problems facing the rich countries in the world were actually often eerily familiar to those we are used to studying in the developing world—people left behind by development, ballooning inequality, lack of faith in government, fractured societies and polity, and so on. We learned a lot in the process, and it did give us faith in what we as economists have learned best to do, which is to be hard headed about the facts, skeptical of slick answers and magic bullets, modest and honest about what we know and understand, and perhaps most importantly, willing to try ideas and solutions and be wrong, as long as it takes us toward the ultimate goal of building a more humane world.

A woman hears from her doctor that she has only half a year to live. The doctor advises her to marry an economist and move to South Dakota.
WOMAN: “Will this cure my illness?”
DOCTOR: “No, but the half year will seem pretty long.”

WE LIVE IN AN AGE of growing polarization. From Hungary to India, from the Philippines to the United States, from the United Kingdom to Brazil, from Indonesia to Italy, the public conversation between the left and the right has turned more and more into a high-decibel slanging match, where harsh words, used wantonly, leave very little scope for backtracking. In the United States, where we live and work, split-ticket voting is at its lowest on record.1 Eighty-one percent of those who identify with one party have a negative opinion of the other party.2 Sixty-one percent of Democrats say they view Republicans as racists, sexists, or bigots. Fifty-four percent of Republicans call Democrats spiteful. A third of all Americans would be disappointed if a close family member married someone from the other

In France and India, the two other countries where we spend a lot of time, the rise of the political right is discussed, in the liberal, “enlightened” elite world we inhabit, in increasingly millenarian terms. There is a clear feeling that civilization as we know it, based on democracy and debate, is under threat.

As social scientists, our job is to offer facts and interpretations of facts we hope will help mediate these divides, help each side understand what the other is saying, and thereby arrive at some reasoned disagreement, if not a consensus. Democracy can live with dissent, as long as there is respect on both sides. But respect demands some understanding.
What makes the current situation particularly worrying is that the space for such conversations seems to be shrinking. There seems to be a “tribalization” of views, not just about politics, but also about what the main social problems are and what to do about them. A large-scale survey found Americans’ views on a broad spectrum of issues come together like
bunches of grapes.4 People who share some core beliefs, say about gender roles or whether hard work always leads to success, seem to have the same opinions on a range of issues, from immigration to trade, from inequality to taxes, to the role of the government. These core beliefs are better predictors of their policy views than their income, their demographic groups, or where they live.

These issues are in some ways front and center in the political discourse, and not just in the United States. Immigration, trade, taxes, and the role of government are just as contested in Europe, India, South Africa, or Vietnam. But views on these issues are all too often based entirely on the affirmation of specific personal values (“I am for immigration because I am a generous person,” “I am against immigration because migrants threaten our identity as a nation”). And when they are bolstered by anything, it is by made-up numbers and very simplistic readings of the facts. Nobody really thinks very hard about the issues themselves.

This is really quite disastrous, because we seem to have fallen on hard times. The go-go years of global growth, fed by trade expansion and China’s amazing economic success, may be over, what with China’s growth slowing and trade wars igniting everywhere. Countries that prospered from that rising tide—in Asia, Africa, and Latin America—are beginning to wonder what is next for them. Of course, in most countries in the affluent West, slow growth is nothing new at this point, but what makes it particularly worrying is the rapid fraying of the social contract that we see across these countries. We seem to be back in the Dickensian world of Hard Times, with the haves facing off against the increasingly alienated
have-nots, with no resolution in sight.5

Questions of economics and economic policy are central to the present crisis. Is there something that can be done to boost growth? Should that even be a priority for the affluent West? And what else? What about exploding inequality everywhere? Is international trade the problem or the solution? What is its effect on inequality? What is the future on trade—can countries with cheaper labor costs lure global manufacturing away from China? And what about migration? Is there really too much low-skilled migration? What about new technologies? Should we, for example, worry about the rise of artificial intelligence (AI) or celebrate it? And, perhaps most urgently, how can society help all those people the markets have left behind?

The answers to these problems take more than a tweet. So there is an urge to just avoid them. And partly as a result, nations are doing very little to solve the most pressing challenges of our time; they continue to feed the anger and the distrust that polarize us, which makes us even more incapable of talking, thinking together, doing something about them. It often feels like a vicious cycle.

Economists have a lot to say about these big issues. They study immigration to see what it does to wages, taxes to determine if they discourage enterprise, redistribution to figure out whether it encourages sloth. They think about what happens when nations trade, and have useful predictions about who the winners and losers are likely to be. They have worked hard to understand why some countries grow and others don’t and what, if anything, governments can do to help. They gather data on what makes people generous or wary, what makes a man leave his home for a strange place, how social media plays on our prejudices.

What the most recent research has to say, it turns out, is often surprising, especially to those used to the pat answers coming out of TV “economists” and high school textbooks. It can shed new light on those debates.
Unfortunately, very few people trust economists enough to listen carefully to what they have to say. Right before the Brexit vote, our colleagues in the UK desperately tried to warn the public that Brexit would be costly, but they felt they were not getting through. They were right. No one was paying much attention. Early in 2017, YouGov conducted a poll in the UK in which they asked: “Of the following, whose opinions do you trust the most when they talk about their field of expertise?” Nurses came first. Eighty-four percent of people polled trusted them. Politicians came last, at 5 percent (though local members of Parliament were a bit more trusted, at 20 percent). Economists were just above politicians at 25 percent. Trust in weather forecasters was twice as high.6 In the fall of 2018, we asked the same question (as well as several others about views on economic issues, which we make use of at various points in the book) to ten thousand people
in the United States.7 There again, just 25 percent of people trusted economists about their own field of expertise. Only politicians ranked lower.

This trust deficit is mirrored by the fact that the professional consensus of economists (when it exists) is often systematically different from the views of ordinary citizens. The Booth School of Business at the University of Chicago regularly asks a group of about forty academic economists, all recognized leaders in the profession, their views on core economic topics. We will often refer to these in the book as the IGM Booth panel answers. We selected ten questions asked of the IGM Booth respondents and posed the same questions to our survey respondents. On most of these issues, economists and our respondents were completely at odds with each other. For example, every single respondent in the IGM Booth panel disagreed with the proposition that “imposing new US tariffs on steel and aluminum
will improve Americans’ well-being.”8 Just over one-third of our respondents shared this view.
