Paul Krugman: Quotes about the world

“Many of the stories economists tell take the form of models—for whatever else they are, economic models are stories about how the world works.”

Paul Krugman

Preface
Economics (4th ed., 2015)

World

“When the economy is in a depression, scarcity ceases to rule. Productive resources sit idle, so that it is possible to have more of some things without having less of others; free lunches are all around. As a result, all the usual rules of economics are stood on their head; we enter a looking-glass world in which virtue is vice and prudence is folly. Thrift hurts our future prospects; sound money makes us poorer. Moreover, that's the kind of world we have been living in for the past several years, which means that it is a kind of world that students should understand. […] Depression economics is marked by paradoxes, in which seemingly virtuous actions have perverse, harmful effects. Two paradoxes in particular stand out: the paradox of thrift, in which the attempt to save more actually leads to the nation as a whole saving less, and the less-well-known paradox of flexibility, in which the willingness of workers to protect their jobs by accepting lower wages actually reduces total employment. […] In times of depression, the rules are different. Conventionally sound policy – balanced budgets, a firm commitment to price stability – helps to keep the economy depressed. Once again, this is not normal. Most of the time we are not in a depression. But sometimes we are – and 2013, when this chapter was written, was one of those times.”

“If economists ruled the world, there would be no need for a World Trade Organization. The economist's case for free trade is essentially a unilateral case- that is, it says that a country serves its own interests by pursuing free trade regardless of what other countries may do.”

“If we discovered that, you know, space aliens were planning to attack and we needed a massive buildup to counter the space alien threat and really inflation and budget deficits took secondary place to that, this slump would be over in 18 months. … There was a Twilight Zone episode like this in which scientists fake an alien threat in order to achieve world peace. Well, this time, we don't need it, we need it in order to get some fiscal stimulus.”

“A temporary evolution of ignorance, a period when our insistence on looking in certain directions leaves us unable to see what is right under our noses, may be the price of progress, an inevitable part of what happens when we try to make sense of the world's complexity.”

“The idea that a country's economic fortunes are largely determined by its success on world markets is a hypothesis, not a necessary truth; and as a practical, empirical matter, that hypothesis is flatly wrong. That is, it is simply not the case that the world's leading nations are to any important degree in economic competition with each other, or that any of their major economic problems can be attributed to failures to compete on world markets.”

“Whether the influence of increasing returns on trade and geography is rising or falling, one thing is clear: much was learned from the intellectual revolution that brought increasing returns into the heart of how we think about the world economy. It wasn't just that economists could make sense of previously puzzling data, we found ourselves able to see things that had previously been in an intellectual blind spot. Many people contributed to this process of enlightenment; I'm proud to have been a part of the journey.”

“The world is full of self-organizing systems, systems that form structures not merely in response to inputs from outside but also, indeed primarily, in response to their own internal logic. Global weather is a self-organizing system; so, surely, is the global economy.”

“The new trade theory picture of the world looks something like this: Each country has, at any given time, a set of broad resources—land, skilled labor, capital, climate, general technological competence. These resources define up to a point the industries in which the country can hope to be competitive on world markets. […] But a country's resources do not fully determine what it produces, because the detailed pattern of advantage reflects the self-reinforcing virtuous circles, set in motion by the vagaries of history.”

“Here, then, is a revised version of Marshall's rules: (1) Figure out what you think about an issue, working back and forth among verbal intuition, evidence, and as much math as you need. (2) Stay with it till you are done. (3) Publish the intuition, the math, and the evidence - all three - in an economics journal. (4) But also try to find a way of expressing the idea without the formal apparatus. (5) If you can, publish that where it can do the world some good.”

“Now I’m not saying that Keynes was right about everything, that we should treat The General Theory as a sort of secular bible - the way that Marxists treat Das Kapital. But the essential truth of Keynes’s big idea - that even the most productive economy can fail if consumers and investors spend too little, that the pursuit of sound money and balanced budgets is sometimes (not always!) folly rather than wisdom - is as evident in today’s world as it was in the 1930s. And in these dangerous days, we ignore or reject that idea at the world economy’s peril.”

“So the story of the baby-sitting co-op is not a mere amusement. If people would only take it seriously—if they could only understand that when great economic issues are at stake, whimsical parables are not a waste of time but the key to enlightenment—it is a story that could save the world.”

“We will not achieve the understanding we need, however, unless we are willing to think clearly about our problems and to follow those thoughts wherever they lead. Some people say that our economic problems are structural, with no quick cure available; but I believe that the only important structural obstacles to world prosperity are the obsolete doctrines that clutter the minds of men.”

“More than four years after the financial crisis began, the world's major advanced economies remain deeply depressed, in a scene all too reminiscent of the 1930s. And the reason is simple: we are relying on the same ideas that governed policy in the 1930s. These ideas, long since disproved, involve profound errors both about the causes of the crisis, its nature, and the appropriate response.These errors have taken deep root in public consciousness and provide the public support for the excessive austerity of current fiscal policies in many countries. So the time is ripe for a Manifesto in which mainstream economists offer the public a more evidence-based analysis of our problems.”

“What’s odd about Friedman’s absolutism on the virtues of markets and the vices of government is that in his work as an economist’s economist he was actually a model of restraint. As I pointed out earlier, he made great contributions to economic theory by emphasizing the role of individual rationality—but unlike some of his colleagues, he knew where to stop. Why didn’t he exhibit the same restraint in his role as a public intellectual?
The answer, I suspect, is that he got caught up in an essentially political role. Milton Friedman the great economist could and did acknowledge ambiguity. But Milton Friedman the great champion of free markets was expected to preach the true faith, not give voice to doubts. And he ended up playing the role his followers expected. As a result, over time the refreshing iconoclasm of his early career hardened into a rigid defense of what had become the new orthodoxy.
In the long run, great men are remembered for their strengths, not their weaknesses, and Milton Friedman was a very great man indeed—a man of intellectual courage who was one of the most important economic thinkers of all time, and possibly the most brilliant communicator of economic ideas to the general public that ever lived. But there’s a good case for arguing that Friedmanism, in the end, went too far, both as a doctrine and in its practical applications. When Friedman was beginning his career as a public intellectual, the times were ripe for a counterreformation against Keynesianism and all that went with it. But what the world needs now, I’d argue, is a counter-counterreformation.”

“Keynesian theory initially prevailed because it did a far better job than classical orthodoxy of making sense of the world around us, and Friedman’s critique of Keynes became so influential largely because he correctly identified Keynesianism’s weak points. And just to be clear: although this essay argues that Friedman was wrong on some issues, and sometimes seemed less than honest with his readers, I regard him as a great economist and a great man.”

“Whose fault is the replacement of serious discussion of world trade by what I have come to think of as "pop internationalism"? To some extent, of course, it is the result of basic human instincts: intellectual laziness, even among those who would be seen as wise and deep, will always be a powerful force. To some extent it also reflects the decline in the influence of economists in general: the high prestige of the profession a generation ago had much to do with the presumed effectiveness of Keynesian macroeconomic policies, and has suffered greatly as macroeconomics has dissolved into squabbling factions. And one should not ignore the role of editors, who often prefer what pop internationalists have to say to the disturbingly difficult ideas of people who know how to read national accounts or understand that the trade balance is also the difference between savings and investment. Indeed, some important editors, like James Fallows at The Atlantic or Robert Kuttner at The American Prospect are pop internationalists themselves; they deliberately use their magazines as platforms for what amounts to an anti-intellectual crusade.”
