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.

Paul Krugman
The whole subject of the liquidity trap has a sort of Alice-through-the-looking glass quality. Virtues like saving, or a central bank known to be strongly committed to price stability, become vices; to get out of the trap a country must loosen its belt, persuade its citizens to forget about the future, and convince the private sector that the government and central bank aren't as serious and austere as they seem.

Paul Krugman
If there were an Economist's Creed, it would surely contain the affirmations 'I understand the Principle of Comparative Advantage' and 'I advocate Free Trade'

Paul Krugman
It's a tribute to the importance of Friedman's work that questions about his legacy bear so directly on contemporary policy issues. But for that reason it's also important not to engage in hagiography. Friedman was a great economist, but like every other great economist in history, he was also wrong about some important things.

Paul Krugman
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.

Paul Krugman
But the honest truth is that what drives me as an economist is that economics is fun. I think I understand why so many people think that economics is a boring subject, but they are wrong. On the contrary, there is hardly anything I know that is as exciting as finding that the great events that move history, the forces that determine the destiny of empires and the fate of kings, can sometimes be explained, predicted, or even controlled by a few symbols on a printed page. We all want power, we all want success, but the ultimate reward is the simple joy of understanding.

Paul Krugman
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.

Paul Krugman
It's widely assumed that bankers have special expertise on economic policy, although nothing in the record supports this belief. (The bankers do, however, have excellent tailors.)

Paul Krugman
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.

Paul Krugman
Where do ideas about economics come from? They come, of course from economists—where by an "economist" I mean someone who thinks and writes regularly about economic issues. But not all economists are alike, and in fact the genus includes two radically distinct species: The professors and the policy entrepreneurs.

Paul Krugman
If there is one single area of economics in which path dependence is unmistakable, it is in economic geography – the location of production in space.

Paul Krugman
Most economists, to the extent that they think about the subject at all, regard the Great Depression of the 1930s as a gratuitous, unnecessary tragedy.

Paul Krugman
… politics determine who has the power, not who has the truth.

Paul Krugman
Many liberals have changed their views in response to new evidence. It's an interesting experience; conservatives should try it some time.

Paul Krugman
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.

Paul Krugman
If Keynes was Luther, Friedman was Ignatius of Loyola, founder of the Jesuits. And like the Jesuits, Friedman's followers have acted as a sort of disciplined army of the faithful, spearheading a broad, but incomplete, rollback of Keynesian heresy. By the century's end, classical economics had regained much though by no means all of its former dominion, and Friedman deserves much of the credit.

Paul Krugman
It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phoney numbers about jobs created or lost.
