The following is a conversation with Paul Krugman, Nobel Prize winner in economics, 00:00:04.960 |
professor at CUNY, and columnist at the New York Times. 00:00:08.840 |
His academic work centers around international economics, economic geography, liquidity traps, 00:00:16.000 |
But he also is an outspoken writer and commentator on the intersection of modern day politics 00:00:22.440 |
and economics, which places him in the middle of the tense, divisive modern day political 00:00:30.280 |
If you have clicked dislike on this video and started writing a comment of derision 00:00:34.280 |
before listening to the conversation, I humbly ask that you please unsubscribe from this 00:00:39.280 |
channel and from this podcast, not because you're conservative, a libertarian, a liberal, 00:00:44.640 |
a socialist, an anarchist, but because you're not open to new ideas, at least in this case, 00:00:50.320 |
especially at its most difficult, from people with whom you largely disagree. 00:00:56.200 |
I do my best to stay away from politics of the day, because political discourse is filled 00:01:01.320 |
with a degree of emotion and self-assured certainty that to me is not conducive to exploring 00:01:07.680 |
questions that nobody knows the definitive right answer to. 00:01:12.840 |
The role of government, the impact of automation, the regulation of tech, the medical system, 00:01:18.360 |
guns, war, trade, foreign policy, are not easy topics and have no clear answers, despite 00:01:25.420 |
the certainty of the so-called experts, the pundits, the trolls, the media personalities 00:01:34.200 |
Please listen, empathize, and allow yourself to explore ideas with curiosity and without 00:01:43.840 |
I will speak with many more economists and political thinkers, trying to stay away from 00:01:48.000 |
the political battles of the day and instead look at the long arc of history and the lessons 00:01:54.360 |

I recently started doing ads at the end of the introduction. 00:02:18.920 |
I'll do one or two minutes after introducing the episode and never any ads in the middle 00:02:25.520 |
I hope that works for you and doesn't hurt the listening experience. 00:02:30.640 |
This show is presented by Cash App, the number one finance app in the App Store. 00:02:35.400 |
Cash App lets you send money to friends, buy Bitcoin, and invest in the stock market with 00:02:40.120 |
fractional share trading, allowing you to buy $1 worth of a stock no matter what the 00:02:46.800 |
Brokerage services are provided by Cash App Investing, a subsidiary of Square and member 00:02:53.220 |
Get Cash App from the App Store and Google Play and use the code LEXPODCAST. 00:02:58.720 |
You'll get $10 and Cash App will also donate $10 to FIRST, one of my favorite organizations 00:03:04.520 |
that is helping to advance robotics and STEM education for young people around the world. 00:03:10.520 |
Since Cash App does fractional share trading, let me say that to me, it's a fascinating 00:03:16.980 |
The order execution algorithm that works behind the scenes to create the abstraction of fractional 00:03:21.920 |
orders for the investor is an algorithmic marvel. 00:03:25.920 |
So big props to the Cash App engineers for that. 00:03:28.600 |
I like it when tech teams solve complicated problems to provide, in the end, a simple, 00:03:33.880 |
effortless interface that abstracts away all the details of the underlying algorithm. 00:03:39.240 |
And now, here's my conversation with Paul Krugman. 00:03:44.240 |
What does a perfect world, a utopia from an economics perspective look like? 00:03:49.160 |
Wow, I don't really, I don't believe in perfection. 00:03:53.960 |
I mean, somebody once said that his ideal was slightly imaginary Sweden. 00:04:00.520 |
I mean, I like an economy that has a really high safety net for people, good environmental 00:04:10.080 |
regulation and, you know, something that's not, that's kind of like some of the better 00:04:16.800 |
run countries in the world, but with fixing all of the smaller things that are wrong with 00:04:24.720 |
Well, obviously, you know, total equality is neither possible nor, I think, especially 00:04:32.000 |
But I think you want one where, basically one where nobody is hurting and where everybody 00:04:41.560 |
Everybody is basically living in the same society. 00:04:45.320 |
So I think it's a bad thing to have people who are so wealthy that they're really not 00:04:59.720 |
I mean, there's, you know, I remember, I'm old enough to remember when there was only 00:05:04.720 |
one phone company and there was really limited choice. 00:05:09.240 |
And I think the arrival of multiple phone carriers and all that has actually, you know, 00:05:21.040 |
But not every industry is, not every activity is suitable for competition. 00:05:26.760 |
So there are some things like healthcare where competition actually doesn't work. 00:05:42.760 |
I mean, there's a famous paper by Kenneth Arrow from 1963, which still holds up very 00:05:47.760 |
well, where he kind of runs down the list of things you need for competition to work 00:05:52.520 |
Basically both sides to every transaction being well-informed, having the ability to 00:05:58.320 |
make intelligent decisions, understanding what's going on. 00:06:05.440 |
Healthcare, so not health insurance, healthcare. 00:06:08.720 |
Well both healthcare and health insurance, health insurance being part of it. 00:06:12.120 |
But no, health insurance is really, the idea that there's effective competition between 00:06:19.680 |
Healthcare, I mean, the idea that you can comparison shop for major surgery is just, 00:06:25.520 |
you know, when people say things like that, you wonder, are you living in the same world 00:06:33.720 |
You know, that piece of well-informed, that was always an interesting piece for me, just 00:06:40.840 |
Because so much beautiful, such a beautiful world is possible when everybody's well-informed. 00:06:47.840 |
My question for you is, how hard is it to be well-informed about anything, whether it's 00:06:51.760 |
healthcare or any kind of purchasing decisions, or just life in general in this world? 00:07:00.360 |
I mean, there's more information at your fingertips than ever before in history. 00:07:07.120 |
The trouble is, first of all, that some of that information isn't true, so it's really 00:07:14.920 |
And then some of it is just too hard to understand. 00:07:18.240 |
So if I'm buying a car, I can actually probably do a pretty good job of looking up, you know, 00:07:25.200 |
going to consumer reports, reviews, you can get a pretty good idea of what you're getting 00:07:30.880 |
If I'm going in for surgery, first of all, you know, fairly often it happens without 00:07:39.560 |
your being able to plan it, but also, you know, medical school takes many, many years, 00:07:46.480 |
and going on the internet for some advice is not usually a very good substitute. 00:07:52.640 |
So speaking about news and not being able to trust certain sources of information, how 00:07:57.720 |
much disagreement is there about, I mentioned utopia, perfection in the beginning, but how 00:08:02.720 |
much disagreement is there about what utopia looks like, or is most of the disagreement 00:08:11.360 |
Oh, I think there's two levels of disagreement. 00:08:24.280 |
I mean, I teach my students that there are, you know, broadly speaking, two views of justice. 00:08:36.880 |
A just society is the one you would choose if you were trying to, the one that you would 00:08:43.800 |
choose to live in if you didn't know who you were going to be, that's kind of John Rawls. 00:08:48.560 |
And the other focuses on process, that a just society is one in which there is no coercion 00:08:55.600 |
except where absolutely necessary, and there's no objective way to choose between those. 00:09:01.520 |
I'm pretty much a Rawlsian, and I think many people are. 00:09:04.920 |
But anyway, so there's a legitimate dispute about what we mean by a just society anyway. 00:09:12.200 |
But then there's also a lot of dispute about what actually works. 00:09:20.960 |
I mean, any card-carrying economist will say that incentives matter, but how much do they 00:09:28.560 |
How much does a higher tax rate actually deter people from working? 00:09:32.000 |
How much does a stronger safety net actually lead people to get lazy? 00:09:40.040 |
I have a pretty strong view that the evidence points to conclusions that are considerably 00:09:47.080 |
to the left of where most of our politicians are, but that there is legitimate room for 00:10:00.480 |
What are some metrics you think about that you keep in mind, like the Gini coefficient, 00:10:04.440 |
but really anything that measures how good we're doing, whatever we're trying to do, 00:10:12.880 |
Well, I'm actually not a fan of the Gini coefficient, not because it's anything- 00:10:18.400 |
Okay, yeah, the Gini coefficient is a measure of inequality, and it is commonly used because 00:10:25.800 |
It usually tracks with other measures, but the trouble is there's no sort of natural 00:10:34.280 |
If you ask me what does a society with a Gini of .45 look like as opposed to a society with 00:10:42.440 |
a Gini of .25, and I can kind of tell you, .25 is Denmark and .45 is Brazil, but there's 00:10:56.960 |
I mean, I look at things like what is, first of all, things like what is the income of 00:11:04.880 |
the median family, what is the income of the top 1%, how many people are in poverty by 00:11:15.320 |
And then I think you want to look at questions like how healthy are people, how is life expectancy 00:11:28.200 |
doing and how satisfied are people with their lives? 00:11:30.560 |
Because there is, that sounds like a squishy number, not so much happiness. 00:11:35.280 |
It turns out that life satisfaction is a better measure than happiness, but life satisfaction, 00:11:43.480 |
I think it's meaningful, if not too rigorous, to say, "Look, according to polling, people 00:11:53.080 |
in Denmark are pretty satisfied with their lives and people in the United States, not 00:11:59.040 |
>>Bellamy And of course, Sweden wins every time. 00:12:01.760 |
>>Yeah, no, actually Denmark wins these days. 00:12:06.320 |
Sweden doesn't do badly, but none of these are perfect. 00:12:12.880 |
But look, I think by and large, there's a bit of a pornography test. 00:12:26.280 |
>>Bellamy We are, our society, there are a lot of virtues to America, but there's a level 00:12:34.360 |
of harshness, brutality, an ability for somebody who just has bad luck to fall off the edge 00:12:42.880 |
that is really, shouldn't be happening in a country as rich as ours. 00:12:49.520 |
So we have somehow managed to produce a crueler society than almost any other wealthy country 00:12:59.760 |
>>Corey What do you think is lacking in the safety net that the United States provides? 00:13:06.560 |
And what are the benefits and maybe limits of a safety net in a country like ours? 00:13:13.520 |
>>Bellamy Well, every other advanced country has some universal guarantee of adequate health 00:13:19.160 |
The United States is the only place where citizens can actually fail to get basic health 00:13:28.280 |
It's not hard to do, everybody else does it, but we don't. 00:13:33.240 |
We've gotten a little bit better at it than we were, but still, that's a big deal. 00:13:37.680 |
We have remarkably weak support for children. 00:13:46.000 |
Most countries have substantial safety, you know, parents of young children get much more 00:13:57.620 |
We have limited care for people, long-term care for the elderly is a very hit and miss 00:14:08.040 |
But I think that the really big issues are that we don't take care of children who make 00:14:15.800 |
the mistake of having the wrong parents, and we don't take care of people who make the 00:14:21.520 |
And those are things that a rich country should be doing. 00:14:25.560 |
Sorry for sort of a difficult question, but what you just said kind of feels like the 00:14:31.800 |
right thing to do in terms of a just society, but is it also good for the economic health 00:14:38.920 |
of a society to take care of the people who are the unfortunate members of society? 00:14:46.360 |
By and large, it looks like doing the right thing in terms of justice is also the right 00:14:55.320 |
If we're talking about a society that has extremely high tax rates that deter, you know, 00:15:01.800 |
remove all incentives to provide a safety net that is so generous that why bother working 00:15:11.960 |
But I don't actually know any society that looks like that. 00:15:15.480 |
Even in European countries with very generous safety nets, people work and innovate and 00:15:23.720 |
And there's a lot of evidence now that lacking those basics is actually destructive, that 00:15:30.880 |
children who grow up without adequate health care, without adequate nutrition, are developmentally 00:15:38.200 |
They don't live up to their potential as adults. 00:15:41.000 |
So the United States actually probably pays a price. 00:15:45.640 |
We're harsh, we're cruel, and we actually make ourselves poorer as a society, not just 00:15:50.920 |
the individuals, by being so harsh and cruel. 00:15:57.880 |
The power of just people acting selfishly and somehow everything taking care of itself 00:16:05.080 |
to where, you know, the economy grows, there's no cruelty, no injustice, that the markets 00:16:17.080 |
Is there power to that idea and what are its limits? 00:16:22.200 |
I mean, there's a reason why I don't think sensible people want the government running 00:16:29.680 |
steel mills or they want the government to own the farms, right? 00:16:36.000 |
The markets are a pretty effective way of getting incentives aligned, of inducing people 00:16:46.440 |
And the invisible hand is saying that, you know, people, farmers aren't growing crops 00:16:50.400 |
because they want to feed people, they're growing crops because they can make money 00:16:54.040 |
by it, but it actually turns out to be a pretty good way of getting agricultural products 00:17:01.560 |
So the invisible hand is an important part, but it's not, there's nothing mystical about 00:17:08.440 |
It's a mechanism, it's a way to organize economic activity, which works well given a bunch of 00:17:13.640 |
preconditions, which means that it actually works well for agriculture, it works well 00:17:18.200 |
for manufacturing, it works well for many services, it doesn't work well for healthcare, 00:17:26.960 |
So there are, having a society which is kind of three quarters invisible hand and one quarter 00:17:36.240 |
visible hand seems to be, something on that order seems to be the balance that works best. 00:17:41.680 |
It's just, you don't want to romanticize or make something mystical out of it, it's just, 00:17:50.040 |
this is one way to organize stuff that happens to have broad but not universal application. 00:17:55.560 |
So then forgive me for romanticizing it, but it does seem pretty magical that, you know, 00:18:02.480 |
I kind of have an intuitive understanding of what happens when you have like five, ten, 00:18:06.320 |
maybe even a hundred people together, the dynamics of that. 00:18:09.000 |
But the fact that these large society of people, for the most part, acting in a self-interested 00:18:14.440 |
way and maybe electing representatives for themselves, that it all kind of seems to work, 00:18:22.080 |
The fact that there's, you know, that right now there's a wide assortment of fresh fruit 00:18:29.920 |
and vegetables in the local markets up and down the street, you know, who's planning 00:18:41.040 |
And the answer is nobody, that's the invisible hand at work, and that's great. 00:18:45.840 |
And that's a lesson that Adam Smith figured out more than 200 years ago, and it continues 00:18:56.480 |
But you know, even Adam Smith has a section in his book about why it's important to regulate 00:19:04.680 |
- Yeah, and that example is actually a powerful one in terms of the supermarket of fruit. 00:19:09.160 |
That was my experience coming from Russia, from the Soviet Union, is when I first entered 00:19:14.040 |
a supermarket and just seeing the assortment of fruit, bananas. 00:19:19.080 |
I don't think I've seen bananas before, first of all, but just the selection of fresh fruit 00:19:28.640 |
And the fact that, like you said, I don't know what made that happen. 00:19:32.760 |
- Well, there is some magic to the market, but as I'm showing my age, but you know the 00:19:39.760 |
old movie quote, "Sometimes the magic works and sometimes it doesn't, and you have to 00:19:51.280 |
And strangely enough in this country today, it seems to get a bad rap. 00:19:57.120 |
Everyone seems to, everybody's against the government. 00:20:00.880 |
- Yeah, well a lot of money has been spent on making people hate the government. 00:20:04.880 |
But the reality is government does some things pretty well. 00:20:11.760 |
Government does health insurance pretty well, so much so, I mean given our anti-government 00:20:16.360 |
bias, it really is true that there are people out there saying, "Don't let the government 00:20:23.520 |
So people actually love the government health insurance program far more than they love 00:20:32.480 |
Basic education, it turns out that your local public high school is the right place to have 00:20:42.720 |
And certainly for-profit education is by and large a nightmare of rip-offs and grift and 00:20:53.600 |
people not getting what they thought they were paying for. 00:20:59.320 |
It's a judgment case, and it's funny, there are things, I mean everybody talks about the 00:21:06.360 |
DMV as being, do you want the economy, actually my experience is that the DMV have always 00:21:13.200 |
Maybe I'm just going to the right DMVs, but in fact a lot of government works pretty well. 00:21:19.200 |
So you'd have to, to some extent you can do these things on a priori grounds. 00:21:24.880 |
You can talk about the logic of why healthcare is not gonna be handled well by the market, 00:21:31.000 |
We tried, or at least some countries have tried nationalizing their steel industries, 00:21:37.000 |
But we've tried privatizing education, and that didn't go well. 00:21:46.320 |
How do you see, what do you think works for tech? 00:21:52.760 |
There are some things that need more regulation. 00:21:56.480 |
We're finding out that the world of social media is one in which competitive forces aren't 00:22:07.400 |
working very well, and trusting the companies to regulate themselves isn't working very 00:22:13.080 |
But I'm on the whole a tech skeptic, not in the sense that I think that tech doesn't work 00:22:18.280 |
and it doesn't do stuff, but the idea that we're living through greater technological 00:22:22.640 |
change than ever before is really an illusion. 00:22:28.080 |
Ever since the beginning of the Industrial Revolution, we've had a series of ethical 00:22:32.360 |
shifts in the nature of work and the kinds of jobs that are available. 00:22:39.440 |
And it's not at all clear that what's happening now is any bigger or faster or harder to cope 00:22:49.440 |
It is a popular notion in today's sort of public discourse that automation is going 00:22:59.680 |
There is something transformational happening now. 00:23:02.800 |
Can you talk about that, maybe elaborate a little bit more? 00:23:08.480 |
Do you not see the software revolutions happening now with machine learning, availability of 00:23:16.160 |
data, that kind of automation, being able to sort of process, clean, find patterns in 00:23:22.360 |
data and do you not see that disrupting any one sector to a point where there's a huge 00:23:32.960 |
I mean, actually, translators, there's really reduced demand for translators because machine 00:23:42.960 |
There are some kinds of things that are changed, but overall productivity growth has actually 00:23:56.000 |
It's been much slower than in some past periods. 00:23:59.820 |
So the idea that automation is taking away all the jobs, the counterpart would be that 00:24:03.760 |
we would be able to produce stuff with many fewer workers than before, and that's not 00:24:09.720 |
There are a few isolated sectors, there are some kinds of jobs that are going away, but 00:24:16.360 |
I mean, New York City used to have thousands and thousands of longshoremen taking stuff 00:24:29.760 |
Now you have the giant cranes taking containers on and off ships in Elizabeth, New Jersey. 00:24:36.960 |
That's not robots, it doesn't sound high tech, but it actually pretty much destroyed an occupation. 00:24:45.600 |
Well, it wasn't fun for the longshoremen, to say the least, but we coped, we moved on, 00:24:59.440 |
We used to be a nation which was mostly farmers. 00:25:07.480 |
And the reason is not that we've stopped eating, it's that farming has become so efficient 00:25:13.440 |
that we don't need a lot of farmers, and we coped with that too. 00:25:16.760 |
So the idea that there's something qualitatively different about what's happening now, so far 00:25:23.320 |
So yeah, your intuition is there is going to be a loss of jobs, but it's just a thing 00:25:30.720 |
There's nothing qualitatively different about this moment. 00:25:33.280 |
Some jobs will be lost, others will be created, as has always been the case so far. 00:25:37.840 |
Maybe there's a singularity, maybe there's a moment when the machines get smarter than 00:25:43.040 |
we are and SkyTech kills us all or something, right? 00:25:46.800 |
But that's not visible in anything we're seeing now. 00:25:55.440 |
I've heard you mention that before in connection with automation. 00:26:00.320 |
So what is that metric, and if there is something qualitatively different, what should we see 00:26:09.720 |
We do have a measure of the economy's total production, real GDP, which is itself, it's 00:26:17.000 |
a little bit of a construct because it's quite literally, it's adding apples and oranges. 00:26:22.460 |
So we have to add together various things, which we basically do by using market prices, 00:26:30.480 |
But it's a reasonable measure of how much the economy is producing. 00:26:34.040 |
Is it goods and, sorry to interrupt, is it goods and services? 00:26:39.240 |
Productivity is, you divide that total output by the number of hours worked. 00:26:45.480 |
So we're basically asking how much stuff does the average worker produce in an hour of work? 00:26:52.640 |
And if you're seeing really rapid technological progress, then you'd expect to see productivity 00:27:02.680 |
For the generation after World War II, productivity rose 2% a year on a sustained basis. 00:27:10.240 |
Then it dropped down for a while, then there was a decade of fairly rapid growth from the 00:27:15.400 |
mid '90s to the mid 2000s, and then it dropped off again. 00:27:24.480 |
You're just not seeing an epical shift in the economy. 00:27:29.000 |
Let me then ask you about the psychology of blaming automation. 00:27:32.120 |
A few months ago you wrote in the New York Times, quote, "The other day I found myself, 00:27:36.800 |
as I often do at a conference, discussing lagging wages and soaring inequality. 00:27:41.760 |
There was a lot of interesting discussion, but one thing that struck me was how many 00:27:45.660 |
of the participants just assumed that robots are a big part of the problem, that machines 00:27:50.760 |
are taking away the good jobs, or even jobs in general. 00:27:54.480 |
For the most part, this wasn't even presented as a hypothesis, just as part of what everyone 00:28:01.120 |
- So why is, maybe can you psychoanalyze the public intellectuals or economists, or us 00:28:09.820 |
actually in the general public, why this is happening? 00:28:14.360 |
Why this assumption has just infiltrated public discourse? 00:28:19.720 |
One is that the particular technologies that are advancing now are ones that are a lot 00:28:31.720 |
When containerization did away with the jobs of longshoremen, well, not a whole lot of 00:28:37.920 |
college professors are close friends with longshoremen, right? 00:28:44.280 |
Then there's a second thing, which is, we just went through a severe financial crisis 00:28:49.960 |
and a period of very high unemployment has finally come down. 00:28:55.760 |
There's really no question that that high unemployment was about macroeconomics, it 00:29:05.840 |
People just have a hard time wrapping their minds around it, and among other things, people 00:29:09.920 |
have a hard time believing that something as trivial as, well, people just aren't spending 00:29:14.080 |
enough can lead to the kind of mass misery that we saw in the 1930s, or the not quite 00:29:19.600 |
so severe, but still serious misery that we saw after 2008. 00:29:24.200 |
And there's always a tendency to say, it must be something big, it must be technological 00:29:28.520 |
change that means we don't need workers anymore. 00:29:31.240 |
There was a lot of that in the '30s, and that same thing happened after 2008, the assumption 00:29:36.120 |
that it has to be some deep cause, not something as trivial as a failure of investor confidence 00:29:53.720 |
A lot of what's happened on wages is at some level political. 00:29:57.640 |
It's the collapse of the union movement, it's policies that have squeezed workers' bargaining 00:30:02.320 |
power, and for kind of obvious reasons, there are a lot of influential people who don't 00:30:10.160 |
They want it to be an inevitable force of nature, technology has made it impossible 00:30:14.840 |
to have people earn middle class wages, and they don't like the story that says actually, 00:30:23.960 |
no, it's kind of the political decisions that we made that have caused this income stagnation, 00:30:29.380 |
and so they're a receptive audience for technological determinism. 00:30:34.160 |
So what comes first in your view, the economy or politics in terms of what has impact on 00:30:44.920 |
That's one of the rules that I was taught in economics, everything affects everything 00:30:51.160 |
But I mean, clearly the economy drives a lot of political stuff, but also clearly politics 00:31:08.000 |
We look at the decline of unions in America and say, well, the world has changed and unions 00:31:13.520 |
don't have a role, but two-thirds of workers in Denmark are unionized, and Denmark has 00:31:20.440 |
the same technology and faces the same global economy that we do, it's just a difference 00:31:25.120 |
in political choices that leads to that difference. 00:31:27.760 |
So I actually teach a course here at CUNY called Economics of the Welfare State, which 00:31:34.240 |
is about things like healthcare and retirement, and to some extent wage policy and so on. 00:31:39.160 |
And the message I keep on trying to drive home is that, look, all advanced countries 00:31:45.880 |
have got roughly equal competence, we all have the same technology, but we make very 00:31:52.060 |
Not that America always makes the wrong choices, we do some things pretty well, our retirement 00:31:56.020 |
system is one of the better ones, but the point is that there's a huge amount of political 00:32:09.160 |
Welfare state is the old term, but it basically refers to all the programs that are there 00:32:16.080 |
to mitigate, if you like, the risks and injustices of the market economy. 00:32:23.120 |
So in the US, the welfare state is Social Security, Medicare, Medicaid, minimum wages, 00:32:29.740 |
When you say welfare state, my first sort of feeling is a negative one. 00:32:34.240 |
Even though I like all, I probably generally, at least theoretically, like all the welfare 00:32:41.920 |
Well, it's been demonized, and to some extent I'm doing a little bit of thumbing my nose 00:32:48.120 |
at all of that by just using the term welfare state. 00:32:55.240 |
But everybody, every advanced country actually has a lot of welfare state, even the US. 00:33:03.480 |
That's a fundamental part of the fabric of our society. 00:33:06.560 |
Social Security, Medicare, Medicaid are just things we take for granted as part of the 00:33:15.360 |
So there's a lot of people on the right wing who are saying, "Oh, it's all socialism." 00:33:23.880 |
And well, I guess, mean what you want them to mean. 00:33:28.200 |
And just today, I told my class about the record that Ronald Reagan made in 1961, warning 00:33:39.580 |
that Medicare would destroy American freedom. 00:33:47.120 |
On the topic of welfare state, what are your thoughts on universal basic income? 00:33:52.160 |
And that's sort of a, not a generic, but a universal safety net of this kind. 00:34:00.140 |
When we talk about social safety net programs, there's always a trade-off between universality, 00:34:09.440 |
which is clean, but means that you're giving a lot of money to people who don't necessarily 00:34:13.840 |
need it, and some kind of targeting, which makes it easier to deal with the crucial problems 00:34:25.760 |
But both has incentive problems and kind of political, and I would say even psychological 00:34:34.360 |
But the great thing about Social Security and Medicare is no questions asked. 00:34:49.760 |
I mean, it's run through my New York Times health insurance, but I didn't have to file 00:34:59.180 |
an application with the Medicare office to prove that I needed it. 00:35:05.600 |
That's good for dignity, and it's also good for the political support, because everybody 00:35:21.260 |
To give everybody a guarantee of an income that's enough to live on comfortably, that's 00:35:29.000 |
What about enough income to carry you over through difficult periods, like if you lose 00:35:37.080 |
Well, we have unemployment insurance, and I think our unemployment insurance is too 00:35:43.440 |
It would be better to have a more comprehensive unemployment insurance benefit. 00:35:50.540 |
But the trouble with something like universal basic income is that either the bar is set 00:35:56.440 |
too low, so it's really not something you can live on, or it's an enormously expensive 00:36:03.000 |
And so at this point, I think that we can do far better by building on the kinds of 00:36:10.680 |
I mean, food stamps, earned income tax credit, we should have a lot more family support policies. 00:36:19.720 |
Can do a lot more to really diminish the amount of misery in this country. 00:36:28.400 |
I mean, it goes kind of hand-in-hand with this belief that the robots are going to take 00:36:35.600 |
And if that was really happening, then I might reconsider my views on UPI, but I don't see 00:36:41.160 |
So are you happy with discourse that's going on now in terms of politics? 00:36:47.760 |
You mentioned a few political candidates, is the kind of thing going on both on Twitter 00:36:55.000 |
and debates and the media, through the written word, through the spoken word, how do you 00:37:00.760 |
assess the public discourse now in terms of politics? 00:37:09.680 |
So at this point, the public discourse that you see if Fox News is your principal news 00:37:21.280 |
source is very different from the one you get if you read the New York Times. 00:37:26.440 |
On the whole, my sense is that mainstream political reporting, policy reporting is A, 00:37:34.160 |
not too great, but B, better than it's ever been. 00:37:37.840 |
Because when I first got into the pundit business, it was just awful. 00:37:45.560 |
And if things did get covered, it was always both sides. 00:37:50.200 |
It's the line that comes back from me writing during the 2000 campaign was that if one of 00:37:55.840 |
the candidates said that the Earth was flat, the headline would be "Views Differ on Shape 00:38:05.880 |
There's still a fair bit of that out there, but it's less true than there used to be. 00:38:08.880 |
And there are more people reporting, writing on policy issues who actually understand them 00:38:20.200 |
But still, how much the typical voter is actually informed is unclear. 00:38:31.440 |
I mean, the Democratic debates, I'm hoping that we finally get down to not having 27 00:38:43.640 |
people on the stage or whatever it is they have. 00:38:46.560 |
But they're reasonably substantive, certainly better than before. 00:38:52.000 |
And while there's a lot of still theater criticism instead of actual analysis in the reporting, 00:39:05.640 |
But from an open-minded perspective, when people on the left and people on the right, 00:39:15.920 |
I think view the others as sometimes complete idiots. 00:39:27.480 |
Is it possible that the people on the right are correct about what they currently believe? 00:39:40.720 |
Or is this division long-term productive for us to sort of have this food fight? 00:39:48.240 |
Well, the trouble you have to confront is that there's a lot of stuff that just is false 00:39:55.480 |
out there, but commands extensive political allegiance. 00:39:59.520 |
So the idea, well, both sides need to listen to each other respectfully. 00:40:04.200 |
I'm happy to do that when there's a view that is worthy of respect, but a lot of stuff is 00:40:11.800 |
And so economics is something where I think I know something, and I'm not sure that I'm 00:40:20.760 |
In fact, I know I've been wrong plenty of times. 00:40:24.840 |
But I think there is a difference between economic views that are within the realm of 00:40:32.160 |
we can actually have an interesting discussion, and those that are just crank doctrines or 00:40:39.680 |
things that are purely being disseminated because people are being paid to disseminate 00:40:46.840 |
So there are plenty of good, serious center-right economists that I'm happy to talk to. 00:40:54.560 |
None of those center-right economists has any role in the Trump administration. 00:40:57.720 |
The Trump administration and by and large Republicans in Congress only want to listen 00:41:05.520 |
And so I think it's being dishonest with my readers to pretend otherwise. 00:41:11.520 |
There's no way I can reach out to people who think that reading Ayn Rand novels is how 00:41:22.320 |
So if you look at Ayn Rand, okay, so you said center-right. 00:41:25.800 |
What about extreme, people who have radical views? 00:41:29.040 |
You think they're not grounded in any kind of data, in any kind of reality? 00:41:36.640 |
I'm just sort of curious about how open we should be to ideas that seem radical. 00:41:44.440 |
Oh, radical ideas is fine, but then you have to ask, is there some basis for the radicalism? 00:41:51.680 |
And if it's something that is not grounded in anything, then, and particularly, by the 00:42:02.000 |
way, if it's something that's been refuted by evidence again and again, and people just 00:42:06.360 |
keep saying it, if it's a zombie idea, and there's a lot of those out there, then there 00:42:11.920 |
comes a point when it's not worth trying to fake respect for it. 00:42:17.000 |
So through the scientific process, you've shown that this idea does not hold water, 00:42:22.520 |
but I like the idea of zombie ideas, but they live on through, it's like the idea that the 00:42:28.080 |
earth is flat, for example, has been, for the most part, disproven. 00:42:34.120 |
But it lives on, actually, and growing in popularity currently. 00:42:39.000 |
And there's a lot of that out there, and you can't wish it away, and you're not being fair 00:42:45.320 |
to either yourself, or if you're somebody who writes for the public, you're not being 00:42:53.000 |
So quantum mechanics is a strange theory, but it's testable, and so while being strange 00:42:59.280 |
is widely accepted amongst physicists, how robust and testable are economics theories, 00:43:06.880 |
if we compare them to quantum mechanics and physics and so on? 00:43:11.200 |
Okay, economics, look, it's a complex system, and it's also one in which, by and large, 00:43:19.800 |
And so economics is never going to be like quantum mechanics. 00:43:24.560 |
That said, you get natural experiments, you get tests of rival doctrines. 00:43:31.360 |
In the immediate aftermath of the financial crisis, there was one style, one basic theory 00:43:40.000 |
of macroeconomics, which ultimately goes back to John Maynard Keynes, that made a few predictions. 00:43:45.160 |
It said, "Under these circumstances, printing money will not be inflationary, running big 00:43:52.040 |
budget deficits will not cause a rise in interest rates, slashing government spending, austerity 00:44:04.660 |
Other people had exactly the opposite predictions, and we got a fairly robust test, and one theory 00:44:13.920 |
Interest rates stayed low, inflation stayed low, austerity countries that implemented 00:44:18.360 |
harsh austerity policies suffered severe economic downturns. 00:44:23.500 |
You don't get much, that's pretty clear, and that's not going to be true on everything. 00:44:29.740 |
But there's a lot of empirical, I mean, the younger economists these days are very heavily 00:44:36.500 |
data-based, and that's great, and I think that's the way to go. 00:44:43.640 |
What theories of economics is there currently a lot of disagreement about, would you say? 00:44:48.800 |
Oh, first of all, there's just a lot less disagreement, really, among serious researchers 00:44:57.820 |
We can track that, the Chicago Booth School has a panel, an ideologically diverse panel, 00:45:04.460 |
and they regularly pose questions, and on most things there's a huge, there's remarkable 00:45:14.180 |
There are a lot of things where people imagine that there's dispute, but the illusion of 00:45:21.340 |
dispute is something that's basically being fed by political forces, and there isn't really. 00:45:27.260 |
There are, I think, questions about what are effective ways to regulate technology industries. 00:45:43.740 |
There's a, or look, I don't follow every part. 00:45:48.860 |
Minimum wages, I think there's pretty overwhelming evidence that a modest increase in the minimum 00:45:55.980 |
wage from current levels would not have any noticeable adverse effect on jobs, but if 00:46:05.540 |
you ask how high could it go, $12 seems pretty safe, given what we know. 00:46:14.980 |
There's some legitimate disagreement there, I think probably, but people have a point. 00:46:22.220 |
20, where is the line at which it starts to become a problem, and the answer is truly 00:46:28.300 |
It's fascinating to try to, such a cool, economics is cool in that sense, because you're trying 00:46:33.460 |
to predict something that hasn't been done before, the impact, the effects of something 00:46:39.780 |
Yeah, you're trying, you're going out of sample, and we have good reason to believe that there 00:46:44.980 |
are, that it's non-linear, that there comes a point at which it doesn't work the way it 00:46:51.940 |
So as an economist, how do you see science and technological innovation? 00:46:56.020 |
When I took various economics courses in college, technological innovation seemed like a no-brainer 00:47:03.220 |
way of growing an economy, and we should invest in it aggressively. 00:47:08.340 |
I may be biased, but it seemed like the various ways to grow an economy, it seems like the 00:47:22.540 |
The first question is, yeah, I mean, all, it's pretty much overwhelming. 00:47:28.180 |
We think we can more or less measure this, although there are some assumptions involved, 00:47:31.780 |
but it's something like 70 to 80% of the growth in per capita income is basically the advance 00:47:40.420 |
It's not just the crude accumulation of capital, it is the fact that we get smarter. 00:47:46.260 |
A lot of that, by the way, is more prosaic kinds of technology. 00:47:50.140 |
So I like to talk about things like containerization or, in an earlier period, the invention of 00:48:05.460 |
That had to be invented, and now all of your deliveries from Amazon are made possible by 00:48:14.060 |
The web stuff is important too, but what would we do without cardboard boxes? 00:48:20.700 |
But all of that stuff is really important in driving economic progress. 00:48:25.860 |
Why don't we invest more in, again, more prosaic stuff? 00:48:35.340 |
Why haven't we built another goddamn rail tunnel under the Hudson River, for which the 00:48:45.060 |
How do you think about, first of all, I don't even know what the word prosaic means, but 00:48:48.260 |
I inferred it, but how do you think about prosaic? 00:48:50.660 |
Is it the really most basic, dumb technology innovation, or is it just the lowest hanging 00:49:04.100 |
When I say prosaic, I mean stuff that is not sexy and fancy and high-tech. 00:49:10.100 |
It's building bridges and tunnels, inventing the cardboard box. 00:49:29.780 |
It is actually using some modern technology and all that, but I don't think they're going 00:49:36.300 |
to make a movie about the guy, whoever it was that invented EasyPass, but it's actually 00:49:46.340 |
To me, it always seemed like it's something that everybody should be able to agree on 00:49:54.820 |
In the same way, the investment in the military and the DOD is huge. 00:50:02.860 |
Not everyone, but there's an agreement amongst people that somehow a large defense is important. 00:50:14.460 |
It always seemed to me like that should be shifted towards, if you want to grow prosperity 00:50:21.960 |
of the nation, you should be investing in knowledge. 00:50:25.300 |
Yes, prosaic stuff, investing in infrastructure and so on. 00:50:28.700 |
I mean, sorry to linger on it, but do you have any intuition? 00:50:40.780 |
I'm reasonably certain that I understand why we don't do it. 00:50:46.740 |
It's because we have a real values dispute about the welfare state, about how much the 00:50:56.940 |
government should do to help the unfortunate. 00:51:00.780 |
And politicians believe, probably rightly, that there's a kind of halo effect that surrounds 00:51:10.660 |
That even though providing people with enhanced social security benefits is really very different 00:51:18.300 |
from building a tunnel under the Hudson River, politicians of both parties seem to believe 00:51:24.060 |
that if the government is seen to be successful at doing one kind of thing, it will make people 00:51:29.200 |
think more favorably on doing other kinds of things. 00:51:32.440 |
And so we have conservatives tend to be opposed to any kind of increase in government spending, 00:51:37.620 |
except military, no matter how obviously a good idea it is, because they fear that it's 00:51:45.980 |
the thin end of the wedge for bigger government in general. 00:51:50.340 |
And to some extent, liberals tend to favor spending on these things, partly because they 00:51:57.020 |
see it as a way of proving that government can do things well, and therefore it can turn 00:52:05.780 |
It's clearly, if you like, what you might have thought would be a technocratic discussion 00:52:13.060 |
about government investment, both in research and in infrastructure, is contaminated by 00:52:18.660 |
the fact that government is government, and people link it to other government actions. 00:52:25.580 |
Perhaps a silly question, but as a species, we're currently working on venturing out into 00:52:32.740 |
So when we start a society on Mars from scratch, what political and economic system should 00:52:44.500 |
First of all, I don't think we're actually gonna do that, but let's... 00:52:48.500 |
Hypothesize that we colonize Mars or something. 00:53:01.060 |
Well, yeah, pure democracy, where people vote directly on everything, is really problematic, 00:53:08.140 |
because people don't have time to try and master every issue. 00:53:15.540 |
We can see what government by referendum looks like. 00:53:18.140 |
There's a lot of that in California, and it doesn't work so good, because it's hard to 00:53:23.140 |
explain to people that the various things they vote for may conflict. 00:53:36.380 |
You kind of know the Winston Churchill thing, right? 00:53:37.860 |
It's the worst system we know, except for all the others. 00:53:42.740 |
But so yeah, sticking with the representative... 00:53:45.940 |
And basically, the American system of regulation and markets and the economy we have going 00:53:57.260 |
If you're gonna start from scratch, you wouldn't want a Senate where 16% of the population 00:54:06.380 |
You probably would want one which is actually more representative than what we have. 00:54:19.420 |
When times are good, all of the various representative democracy systems, whether it's parliamentary 00:54:26.500 |
democracies or a US style system, whether you have a prime minister or the head of state 00:54:32.860 |
as an elected president, they all kind of work well when times are good, and they all 00:54:42.060 |
But something like that is, given what we've seen through history, it's the least bad system 00:54:57.180 |
I'm a big fan of the TV series, The Expanse, and it's kind of gratifying that out there 00:55:10.180 |
In a brief sense, so amongst many things, you're also an expert at international trade. 00:55:23.460 |
So I can understand trade between two people, say two neighboring farmers. 00:55:31.820 |
But internationally, when you start talking about nations and nations trading, it seems 00:55:37.540 |
So from a high level, why is it so complicated? 00:55:41.460 |
What are all the different factors that weigh the objectives that need to be considered 00:55:48.260 |
And maybe feeding that into a question of, do you have concerns about the two giants 00:55:54.780 |
right now of the US and China, and the tension that's going on with the international trade 00:56:02.140 |
Well, first of all, international trade is not really that different from trade among 00:56:06.860 |
It's vastly more complex, and there are many more players. 00:56:13.340 |
But in the end, the reasons why countries trade are pretty much the same as the reasons 00:56:18.980 |
Countries trade because they're different, and they can derive mutual advantage from 00:56:24.180 |
concentrating on the things they do relatively well. 00:56:35.580 |
Individuals have to decide whether to be a surgeon or an accountant. 00:56:38.660 |
It's probably not a good idea to try and be both. 00:56:42.380 |
And countries benefit from specializing just because of the inherent advantages of specialization. 00:56:49.460 |
So now, the fact that it's a big world, and we're talking about millions of products being 00:56:56.060 |
traded, and in today's world, often trade involves many stages. 00:57:02.260 |
So that made in China iPhone is actually assembled from components that are made all over the 00:57:10.220 |
But it doesn't really change the fundamentals all that much. 00:57:19.420 |
The very little secret of international trade conflict is that actually it's not... 00:57:26.060 |
Conflicts among countries are really not that important. 00:57:29.540 |
U.S. trade is beneficial to both sides, to both countries, but it has big impacts on 00:57:40.180 |
So the growth of U.S. trade with China has made both U.S. and China richer, but it's 00:57:47.620 |
been pretty bad for people who were employed in the North Carolina furniture industry, 00:57:54.380 |
who did find that their jobs were displaced by a wave of imports from China. 00:58:07.140 |
We have some real problems with China, although they don't really involve trade so much as 00:58:11.540 |
things like respect for intellectual property. 00:58:17.380 |
Not clear that those real problems that we do have with China have anything to do with 00:58:23.100 |
The current trade war seems to be driven instead by a fundamentally wrong notion that when 00:58:30.100 |
we sell goods to China, that's good, and when we buy goods from China, that's bad. 00:58:36.860 |
Is trade with China in both directions a good thing? 00:58:40.460 |
Yeah, we would be poorer if it wasn't for it. 00:58:43.740 |
But there are downsides, as there are for any economic change. 00:58:47.340 |
It's like any new technology makes us richer, but often hurts some people. 00:58:53.460 |
Trade with China makes us richer, but hurts some people. 00:58:56.780 |
And I wouldn't undo what has happened, but I wish we had had a better policy for supporting 00:59:05.620 |
and compensating the losers from that growth. 00:59:09.460 |
So we live in a time of radicalization of political ideas, Twitter mobs, and so on. 00:59:15.820 |
And yet here you are in the midst of it, both tweeting and writing in the New York Times 00:59:21.460 |
articles with strong opinions, riding this chaotic wave of public discourse. 00:59:26.660 |
Do you ever hesitate or feel a tinge of fear for exploring your ideas publicly and unapologetically? 00:59:37.820 |
It's not too hard to imagine scenarios in which this is going to, I might personally 00:59:47.180 |
And I mean, I am the king of hate mail, I get amazing correspondence. 01:00:01.780 |
So I know I don't usually get, in fact, if I don't get a wave of hate mail after a column, 01:00:11.220 |
So what do you make of that as a person who's putting ideas out there? 01:00:16.340 |
If you look at the history of ideas, the way it works is you write about ideas, you put 01:00:22.460 |
But now when there is so much hate mail, so much division, what advice do you have for 01:00:28.860 |
yourself and for others trying to have a discussion about ideas, difficult ideas? 01:00:36.300 |
I mean, for most economists, just do your research. 01:00:44.260 |
We can't all be public intellectuals and we shouldn't try to be. 01:00:47.140 |
And in fact, I'm glad that I didn't get into this business until I was in my late 40s. 01:00:55.180 |
I mean, it's probably best to spend your decades of greatest intellectual flexibility addressing 01:01:03.820 |
deep questions, not confronting Twitter mobs. 01:01:10.940 |
And as for the rest, I think when you're writing about stuff, sort of dance like no one's watching, 01:01:24.420 |
Trying to make it, obviously, trying to make it comprehensible and persuasive, but don't 01:01:30.220 |
let yourself get intimidated by the fact that some people are going to say nasty things. 01:01:40.580 |
You can't do your job if you are worried about criticism. 01:01:47.660 |
Well, I think I speak for a lot of people in saying that I hope that you keep dancing 01:01:52.220 |
like nobody's watching on Twitter and New York Times and books. 01:02:01.660 |

And now let me leave you some words from Adam Smith in The Wealth of Nations, one of the 01:02:36.820 |
most influential philosophers and economists in our history. 01:02:40.980 |
"It is not from the benevolence of the butcher, the brewer, or the baker that we expect our 01:02:45.860 |
dinner, but from their regard to their own interest. 01:02:49.820 |
We address ourselves not to their humanity, but to their self-love, and never talk to 01:02:54.900 |
them of our necessities, but of their advantages." 01:03:00.540 |
Thank you for listening and hope to see you next time.
