The very nature of economics is rooted in nationalism. ... It [was] developed ... in the hope of throwing light upon questions of policy. But policy means nothing unless there is an authority to carry it out, and authorities are national.

Don't go to great trouble to optimize something that never should be done at all. Aim to enhance total systems properties, such as creativity, stability, diversity, resilience, and sustainability - whether they are easily measured or not.

Perhaps the most difficult ethical problem of the scientific community arises not so much from conflict with other subcultures as from its own success. Nothing fails like success because we don't learn from it. We learn only from failure.

In the European context tax rates are high and government expenditure is focused on current expenditure. A "good" consolidation is one where taxes are lower and the lower government expenditure is on infrastructures and other investments.

A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.

It is indeed paradoxical that, while the apologists of capitalism usually consider the 'price mechanism' to be the great advantage of the capitalist system, price flexibility proves to be a characteristic feature of the socialist economy.

We do not influence the course of events by persuading people that we are right when we make what they regard as radical proposals. Rather, we exert influence by keeping options available when something has to be done at a time of crisis.

As Ludwig von Mises conclusively demonstrated in 1912, money does not and cannot originate by order of the State or by some sort of social contract agreed upon by all citizens; it must always originate in the processes of the free market.

Looking back, I underestimated the risks. The planet and the atmosphere seem to be absorbing less carbon than we expected, and emissions are rising pretty strongly. Some of the effects are coming through more quickly than we thought then.

If you want a simple model for predicting the unemployment rate in the United States over the next few years, here it is: It will be what Greenspan wants it to be, plus or minus a random error reflecting the fact that he is not quite God.

But the point of a progressive revenue tax is that you create incentives both for breakups, you penalize the acquisitions, and you encourage the development of models where the customers are customers and they know what they're giving up.

The real danger from advertising is that it helps to shatter and ultimately destroy our most precious non-material possessions: the confidence in the existence of meaningful purposes of human activity and respect for the integrity of man.

Retirement savings is probably behavioral economists' greatest success story. It is a prototypical behavioral-economics problem because saving for retirement is cognitively hard - figuring out how much to save - and requires self-control.

I abhor Earth Hour. Abundant, cheap electricity has been the greatest source of human liberation in the 20th century. Every material social advance in the 20th century depended on the proliferation of inexpensive and reliable electricity.

If the whole process of learning from failure means discarding stuff that's not working, but in fact, our natural reaction is to keep going, to throw more money behind it, to throw more emotional energy behind it... that's a real problem.

Students who are alien and hostile to the education process ought to be removed. You say, "What will we do with them?" I say that's a secondary issue. The first priority is to stop thugs from making education impossible for everyone else.

Europe is very critical to the United States in the sense not only do we have a fourth of our exports there, but more importantly, a significant proportion of the foreign affiliate profits in fact, half of U.S. corporations, are in Europe.

I am a data hound and so I usually end up working on whatever things I can find good data on. The rise of Internet commerce completely altered the amount of information you could gather on company behavior so I naturally drifted toward it.

the wealthy white western minority of the world could not hope to prosper if most of the rest of mankind were foundering in hopeless poverty. Islands of plenty in a vast ocean of misery never have been a good recipe for commercial success.

Monetary policy has less room to maneuver when interest rates are close to zero, while expansionary fiscal policy is likely both more effective and less costly in terms of increased debt burden when interest rates are pinned at low levels.

The Mexican debt crisis, Latin American debt crisis, the crises of the 1990s, the Wall Street stock market crash, and other events should have reminded us, and did remind us, that financial instability remains a concern, remains a problem.

Reforms to product and labour markets, education, innovation, green growth, competition, taxes, health - they are the things that should be the object of our primary focus in the context of a long-term strategy to restore sustained growth.

You saw on your TV what happened in New Orleans after Hurricane Katrina. The Reserves or National Guard are usually the people we use for those national emergencies. They weren't here, they were over in Iraq, and so we were less protected.

We often hear people talk about the concept of 'uberization,' where a new technology completely turns an industry on its head and forces us to rethink the way things have always been done. No industry will remain untouched by these forces.

Bitcoin is not an actual physical coin, and if computers are shut down, you can't buy or sell them. That's why nothing will ever replace gold and silver coins themselves, and all investors should have them at home or in a safe deposit box.

For the West, the enemy was not "socialism" but capitalism. How to tame and subdue the polar bear, how to take over the talent, the science, the technology, how to buy out the human capital, how to acquire the intellectual property rights?

My view is that one should diversify broadly across different fund investments. However, it's tough for investors to try to pick the appropriate risk level that they should manage their funds at. Having a personal adviser would be helpful.

Seven habits that help produce the anything-but-efficient markets that rule the world. 1. Think short term. 2. Be greedy. 3. Believe in the greater fool 4. Run with the herd. 5. Overgeneralize 6. Be trendy 7. Play with other people's money

We have a lot of evidence on what happens when you raise the minimum wage. And the evidence is overwhelmingly positive: Hiking the minimum wage has little or no adverse effect on employment while significantly increasing workers' earnings.

The Malthusian Theory - that mankind, for biological and sociological reasons, is so fertile, so fecund, that if you started out with the new continent and plenty of land for everybody, in several generations we would multiply our numbers.

The heathen mythology not only was not true, but was not even supported as true; it not only deserved no faith, but it demanded none. The very pretension to truth, the very demand of faith, were characteristic distinctions of Christianity.

As there are dim-sighted people who live in a sort of perpetual twilight, so there are some who, having neither much clearness of head nor a very elevated tone of morality, are perpetually haunted by suspicions of everybody and everything.

During the two centuries since the publication of 'The Wealth of Nations,' the main activity of economists, it seems to me, has been to fill the gaps in Adam Smith's system, to correct his errors and to make his analysis vastly more exact.

Accepting trial and error means accepting error. It means taking problems in our stride when a decision doesn't work out, whether through luck or misjudgment. And that is not something human brains seem to be able to do without a struggle.

Michael Moore didn't have to worry that anyone would misinterpret the title of his film, 'Capitalism: A Love Story,' because in Hollywood, no one loves capitalism. That's too bad, because Hollywood is one of capitalism's greatest successes.

Human development, as an approach, is concerned with what I take to be the basic development idea: namely, advancing the richness of human life, rather than the richness of the economy in which human beings live, which is only a part of it.

Japan became an imperialist country in many ways, but that was much later, after it had already made big progress. I don’t think Japan’s wealth was based on exploiting China. Japan’s wealth was based on its expansion in international trade.

I think women - relative to men - tend to feel that they have to do the household chores on top of everything else. This becomes even worse once you have kids. It's enough to have a full time job; a full time job plus a family is even more.

Trade protection accumulates upon a single point the good which it effects, while the evil inflicted is infused throughout the mass. The one strikes the eye at a first glance, while the other becomes perceptible only to close investigation.

Stores don't order merchandise unless they think they can sell it right away. Manufacturers and builders don't produce unless they have buyers lined up. My business contacts describe this as a paradigm shift and they believe it's permanent.

Apart from their work and production, households perform other important economic functions. Most CONSUMPTION occurs within the household. ... In developed capitalist economies, private consumption spending accounts for half or more of GDP.

I do not regard the Keynesian revolution as a great intellectual triumph. On the contrary, it was a tragedy because it came so late. Hitler had already found out how to cure unemployment before Keynes had finished explaining why it occured.

In 1958, Anne and I returned to Australia, where I got a very attractive research position at the Australian National University in Canberra. But soon I felt very isolated because at that time game theory was virtually unknown in Australia.

Consumer wants can have bizarre, frivolous, or even immoral origins, and an admirable case can still be made for a society that seeks to satisfy them. But the case cannot stand if it is the process of satisfying wants that create the wants.

Few economic problems, if any, are difficult of solution. The difficulty, all but invariably, is in confronting them. We know what needs to be done; for reasons of inertia, pecuniary interest, passion or ignorance, we do not wish to say so.

How can I adopt a creed which, preferring the mud to the fish, exalts the boorish proletariat above the bourgeois and the intelligentsia who, with whatever faults, are the quality in life and surely carry the seeds of all human advancement?

During waves of terror attacks, Israel's national police chief will call on all concealed-handgun permit holders to make sure they carry firearms at all times, and Israelis have many examples where concealed permit holders have saved lives.

Equality of economic opportunity, in the context of private property, means equality of opportunity for the millions of capital-less households of today to buy, pay for, and employ in their lives the non-human factor of production, capital.

The idea that full employment without property ownership will solve the world's problems is utter nonsense. The Keynesian concept that the function of capital is merely to amplify labor, not independently produce wealth is simply blindness.
