I'm not a vegetarian. But I think people who are vegetarians, they are actually more virtuous than the rest of us. I think they should be admired.

Often, economists spend their energies squabbling with one another, but arguably the more important contrast is between our broadly liberal economic worldview and the various alternatives - common around the globe - that postulate natural hierarchies of religion, ethnicity, caste and gender, often enforced by law and strict custom.

When I hear people express extreme optimism about the Internet, I say, we've had it in mature form for about ten years. Macroeconomically speaking, those are about the worst 10 years we've had since about the 1930s. I don't blame the Internet for that - that would be ridiculous.

At least in the United States, most economic resentment is not directed toward billionaires or high-roller financiers - not even corrupt ones. It's directed at the guy down the hall who got a bigger raise. It's directed at the husband of your wife's sister, because he earns 20 percent more than you do.

Some Google employees have their self-driving vehicles take them to work. These car robots don't look like something from 'The Jetsons'; the driverless features on these cars are a bunch of sensors, wires, and software. This technology 'works.'

I think as individuals, people overrate the virtues of local food. Most of the energy consumption in our food system is not caused by transportation. Sometimes local food is more energy efficient. But often it's not. The strongest case for locavorism is to eat less that's flown on planes, and not to worry about boats.

The 'low' quality of many American films, and of much American popular culture, induces many art lovers to support cultural protectionism. Few people wish to see the cultural diversity of the world disappear under a wave of American market dominance.

The way to make the world a better place, through your eating, is simply to eat a bit less meat. Local is sometimes good, sometimes bad. But even when it's good, its environmental impact is relatively small compared to other possible improvements.

I see three forces militating in favor of growing inequality: increasing measurement of worker value added, automation through smart software, and globalization.

We need to accept the principle that sometimes poor people will die just because they are poor.

What the banking system needs is creditors who monitor risk and cut their exposure when that risk is too high. Unlike regulators, creditors and counterparties know the details of a deal and have their own money on the line.

France has not only built a bureaucratic barrier against American culture, it has constructed a notorious intellectual case against it as well. The French spend hundreds of millions of dollars subsidizing film production, extend interest-free loans to designated filmmakers, and have placed quotas not only on imports but on television time.

At fancy and expensive restaurants (say, $50 and up for a dinner), you can follow a simple procedure to choose the best meal. Look at the menu and ask yourself: 'Which of these items do I least want to order?' Or: 'Which one sounds the least appetizing?' Then order that item.

A lot of local food is very tasty. I'm very happy to eat it. I just don't think it's the same thing as saving the world.

Most restaurants in most cities, including Washington, are at a sort of mid-level. They're somewhat trendy, or they have some sort of gimmick, or they're somewhat expensive. And they make a lot of money off drinks. I tell people don't go to most of them, unless your goal is just to socialize.

In truth, it's not the shareholders of the American International Group who benefited most from its bailout; they were mostly wiped out. The great beneficiaries have been the creditors and counterparties at the other end of A.I.G.'s derivatives deals - firms like Goldman Sachs, Merrill Lynch, Deutsche Bank, Societe Generale, Barclays and UBS.

For the very top earners, vision and inspiration are essential. You need those to become the next Steve Jobs, but perhaps not to be the highest paid dentist in Beverly Hills.

For the U.S., I think we should have a carbon tax, for environmental reasons.

To get anything done, Obama has to be seen as having winning economy - which isn't easy.

Presidents always want to do nice, noble, long-run things, and Congress is less keen to do so. We've seen that throughout the history of this country.

I think a lot of people will be liberated from a lot of oppressive manufacturing jobs, or a lot of service jobs, because they'll be done by computers. There'll be the world's best education available online and free.

Everything will have a Yelp review. And if you're a worker, there will be like credit scores. There already are to some extent. How reliable are you? How many jobs have you had? Have there been lawsuits filed against you? How many traffic tickets?

Countries with lots of unmarried young men are the most vulnerable to sudden upheavals - this is what fueled the Arab Spring.

After aircraft production, the entertainment industry is America's largest source of trade surplus.

A bad or mediocre meal is more than just an unpleasant taste, it is an unnecessary negation of one of life's pleasures - a wasted chance to refine our palates, learn about the world, and share a rewarding experience.

Economics evolved as a more moral and more egalitarian approach to policy than prevailed in its surrounding milieu. Let's cherish and extend that heritage. The real contributions of economics to human welfare might turn out to be very different from what most people - even most economists - expect.

When humans team up with computers to play chess, the humans who do best are not necessarily the strongest players. They're the ones who are modest and who know when to listen to the computer. Often, what the human adds is knowledge of when the computer needs to look more deeply.

There's so much free material on the Internet you can learn from, and some people are pure self-starters: they pick up computers and teach themselves everything. Certainly there are millions of people like that. But at the same time, I think it's a pretty small percentage of the population.

Most of us are not pure self-starters; most people need role models, they need coaches, they need exemplars, they maybe need some discipline or some rewards. We need to be motivated.

I don't really watch TV.

When you look at the actual data on technological innovation, one thing you see is that what I call the 'low-hanging fruit' has been exhausted. So radio, flush toilets, electricity, and automobiles - a lot of very basic inventions - have spread to almost all households.
