Paul Krugman quotes
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
We're living in a Dark Age of macroeconomics. Remember, what defined the Dark Ages wasn't the fact that they were primitive - the Bronze Age was primitive, too. What made the Dark Ages dark was the fact that so much knowledge had been lost, that so much known to the Greeks and Romans had been forgotten by the barbarian kingdoms that followed.
Paul Krugman
There is no economic policy. That's really important to say. The general modus operandi of the Bushies is that they don't make policies to deal with problems. They use problems to justify things they wanted to do anyway. So there is no policy to deal with the lack of jobs. There really isn't even a policy to deal with terrorism. It's all about how can we spin what's happening out there to do what we want to do.

I know that when I look at today's Mexicans and Central Americans, they seem to me fundamentally the same as my grandparents seeking a better life in America. On the other side, however, open immigration can't coexist with a strong social safety net; if you're going to assure health care and a decent income to everyone, you can't make that offer global. So Democrats have mixed feelings about immigration; in fact, it's an agonizing issue.
Paul Krugman
Economists, like everyone, have their political biases, but these are by no means as strong an influence on what they are willing to consider as you might think. For example, one might have thought that strongly liberal economists like, say, James Tobin would be at least mildly sympathetic to the views of radical economists who draw their inspiration from Marx, or of heterodox economic thinkers like Galbraith. After all, in such fields as history and sociology the Marxist or post-Marxist left has long received a respectful hearing. And yet you don't find this happening: liberal economists are almost as quick as their conservative colleagues to condemn heterodox leftist ideas as foolish it was the liberal Robert Solow, not Milton Friedman, who defended orthodoxy in the bitter "capital controversy" with British radicals.
Paul Krugman
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.
Paul Krugman
That's a hard answer to accept, especially for those American policy intellectuals who recoil from the dreary task of reducing deficits and raising the national savings rate. But economics is not a dismal science because the economists like it that way; it is because in the end we must submit to the tyranny not just of the numbers, but of the logic they express.
Paul Krugman
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.
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.
