Hey, podcast listeners, the episode you're about to hear is called Fixing the World,
Bang for the Buck Edition. In it, you'll hear how a bunch of economists have teamed up to measure
the ROI or return on investment for the development goals set by the United Nations.
In other words, if you only have $100, or in the case of the UN, $100 billion, let's say,
to fight something like global poverty,
what's the best way to spend that money?
What's the ROI on early education versus job training versus small business subsidies?
We do this kind of thing a lot here at Freakonomics Radio,
try to measure the ROI on things that aren't so easy to measure.
So let me turn this around and ask you a question.
What is the ROI for you from Freakonomics Radio?
Does the time you spend listening to this show
make your life in any way better,
more pleasurable, less bewildering?
If you believe it does,
if the number you put on its value
is anything at all north of zero,
well, I hope then you will consider
making a contribution to WNYC, the public radio station here in New York that produces
our show.
Just go to Freakonomics.com and hit the donate button.
Any and all contributions are appreciated, although you will find the rewards get better
as you climb the dollar ladder.
Freakonomics radio t-shirts and mugs, autographed books, things like that.
And if you decide that this program isn't worth anything to you, not even five bucks,
well, now we'll know that too.
And we'll work harder in the future to make it worth more.
But I do hope that you'll go to Freakonomics.com to donate.
Thanks a million.
Or a billion, a hundred billion, whatever the case may be. Copenhagen Consensus Center, where we bring together lots of economists and seven Nobel Orts to think about where do we spend money and do the most good per dollar spent.
Let's say you want to fix the world in some fashion, to some degree, as daunting and
difficult as that may be. And let's say that you have more than $100 billion a year to spend.
This is not a fictional scenario.
This is what really happens.
Development aid is a huge industry.
So what kind of problems do we spend money on?
And how are those problems chosen?
We focus on a lot of different issues in the world, and many of them we focus on because
they get lots of attention.
They're in the press. They have good stories. They have lots of crying kids or cute animals.
But of course, in reality, what we need to do if we want to do good is to focus on where do we do
the most good for every dollar spent. Now, a long time ago, I dabbled a little in this conversation
on what should we be focusing on, and I was pretty sure somebody must have looked at that.
Surely somebody has given us the menu list, if you will, of society's different choices
and told us what are the bang for the buck for these different issues.
Turns out that really nobody has.
And for a fairly simple reason, because if you are working in any particular area, say
if you work for education to small kids, or if you
work for nutrition, or if you work in global warming, or saving pandas, or whatever that
thing is, you don't really want to find out what's the smartest thing, because there's a good chance
it's not going to be your thing. But of course, we want to find out as a society, because we want
to do the most good. So that's discouraging, although obviously you provide an alternative to that.
Let me ask you this, even within a realm, whether you're saving pandas or thinking about
poverty, famine, education, let's say I'm focused on just the one realm and I'm not
going to compare it to all the other projects.
At least within my realm, don't I want to be vigilant about measuring ROI, about seeing what I get for
the money that we put into it? And there is definitely more of that. If you look, for instance,
in disease, the World Health Organization has a disease priorities project where they've actually
looked at what's the bang for the buck for more than 300 different diseases. But when you're a
doctor and you're out there and you're confronted with a specific type
of patients at your place, so you see malaria or you see schistosomiasis or you see some other
disease, it's really hard to say, well, maybe I should be somewhere else on the planet doing
something else. You're going to say, I want to cure this disease. But there's a lot more we can do
for this amount of money. Just to give you one example,
you can probably save one person from dying from malaria for about $1,000. You can probably save
one person from dying from HIV AIDS for about $10,000. Now, both are good deals, but you have
to ask yourself, don't we want to first save 10 people from malaria before you save one person
from HIV?
From WNYC, this is Freakonomics Radio, the podcast that explores the hidden side of everything.
Here's your host, Stephen Dupner.
Bjorn Lomborg runs the Copenhagen Consensus Center. What it tries to do is tell governments and other nonprofits the best way to spend money to solve problems around the world.
The best as in the most useful, most rational way, as opposed to just attacking the noisiest problems or the most politically appealing ones.
We are a very small organization.
We are really just the guys who commission all the smart economists around the world to write the papers that actually estimate what are the costs and benefits.
So we are seven full-time employees.
Most of us are based in Budapest.
I live in Prague.
Our deputy lives in Sweden.
We have one guy working in Australia, one in the US.
But mostly, we just make sure we find the smartest people on the planet, the smartest economists doing education or doing health or doing global warming, and then asking them,
what can you do?
How much will that cost?
And how much good will it do?
We have a number of Nobel laureates that look across all these
different areas and basically say, overall, what's the smartest thing to do? What's the
next smartest thing to do? The third and so on, essentially rank all the great outcomes
that we can look at. Do you pay the economists for this analysis? Oh, yes. Okay. Where does
the money come from? How much do you spend in a given year and where's the money come from?
We used to be funded by the Danish government from 2004 until 2012. One of the things the
Danish government did not like was that we said, yes, global warming is real and it is a challenge,
but the typical way that we solve it turns out to be a pretty poor investment of resources.
When there was a change of governments here, we went from a center-right to a center-left
government. They actually cut off our funding and we've moved to the U.S. where we get funding from private individuals,
and we're trying to find a long-term solution for actually getting funding.
So we're 501c3, a nonprofit in the U.S.
We used to have a budget of about $2 million a year.
Right now, we probably have a budget of a little more than $1 million a year,
and we get it from private donations. And for those who want to get under the hood of where
those donations come from, since the current climate suspects that every donation comes with
an agenda attached, describe for me the provenance of that money and if there are strings attached.
There's no strings attached. We're very clear on saying we take no money from
fossil fuels and we do not let anyone direct what we are going to do. So we have only taken money
from private individuals and foundations that have accepted that. With that said, almost all of them
have wanted to remain anonymous. There are a few like the Kauffman Foundation, for instance,
who have accepted to say that they've given money to us. We've also got money from New Ventures
Foundation, from the Randolph Foundation, and from Rush Foundation. Talk for a minute, Bjorn,
let's go back to the book that put you on the map, at least here, and I assume there as well, the skeptical environmentalist,
which made a lot of environmentalists skeptical about you, to say the least. Talk to me about
why you came to the problem of climate change at all. You trained as a political scientist,
yes?
Yes, yes.
Why you came to the problem at all, what your conclusions were then in that book,
and where they've gotten to today, 13 years later.
So, fundamentally, my book, The Skeptical Environmentalist, was really a result of my own personal journey.
I read an interview with an American economist called Julian Simon back in Wired Magazine in 1997.
And he said, listen, you think everything's getting worse with the environment, but actually most things are getting better.
My immediate sort of reaction was right wing American propaganda.
But he said one thing that really stuck with me.
He said, go check the data.
And so I decided, yeah, OK, I'm going to check his data.
I'm going to get some of my smartest students together.
We're going to have a fun half year and prove him wrong. But as it turned out, and if you also think about it, of course, in many
of the obvious parameters, air pollution, water pollution has come down dramatically. We're better
fed. We have higher incomes. We live longer. We have better education. So most of the things in
the world are actually going in the right direction, especially if you live in the rich part
of the world. So we realized, oh, wait, there is actually improvement. This does not mean that
there are no problems. There are still lots of problems in the world, but it suddenly means
instead of saying the world is coming to an end, we can start having a sensible conversation of,
all right, so which of the many remaining problems should we be most focused on? There's no doubt
global warming is real and it is a problem. But if you implement
the Kyoto Protocol, which back then was sort of the gold standard of what we were trying to do
with climate, we could see it would have a huge cost. The economic estimate was about $180 billion
a year. And it would have a fairly small benefit. We would postpone global warming somewhere between
two and five years by the end of the century. So I was merely
comparing the fact that it was an interesting fact. You could actually give clean drinking
water and sanitation to every single person on the planet for $180 billion once. Isn't it curious
to say we could either spend $180 billion every year and do fairly little about global warming,
or just spend it once and do an
amazing amount of good for more than a billion people. That was the start of my point of saying,
well, we should compare different priorities. And of course, I thought somebody else must have made
this prioritization list. Somebody else must have looked at that, and nobody had. And so I thought,
well, somebody should, and maybe it should be us. You identified yourself at the top as a public intellectual. You also
are a professor at a business school, correct? Yes.
With the Copenhagen Consensus Project, what's in it for you? Why are you doing this?
Well, I used to do game theory and computer simulations, and I was writing papers that probably, if I was lucky, a hundred people would read in my career.
And I actually really, really liked it.
I'm sort of a nerdy guy.
I'm the kind of guy who can download Excel sheets at Saturday night and actually think it's really funny.
So, you know, it sort of gives you a sense of what drives me. And so I was totally content with living that life. But one of the things I also try to do is
when you do stuff in academia, you should also help bring that argument out. So when I'd done
my PhD, somebody from Danish radio actually called like drive time radio, one of the most listened
programs. And they said, would you care to talk in our program for three minutes about your PhD?
I wasn't smart enough at the time, but you know, somebody said, I should have said, yeah,
that's like one minute per year. Sure. And so, you know, I tried to convey what was it that I'd
done, because I think it's important that we give back. If we have all this knowledge and information
that should go to society, because after all, they're the guys who are paying for us reading good books. And so in some way, what I'm trying
to do with the Copenhagen Consensus and the arguments that we're engaged with right here now
is to try and give back that sort of argument so that we can make better decisions. And hopefully,
at the end of the day, we'll end up making at least slightly better decisions. And so the world will end up being a much better place.
Okay.
Let's talk about then your current project.
Let's start with development aid generally or development goals generally.
How much is spent globally in a year, if you can tell me, on development aid?
Last year, we spent $134 billion of overseas development aid in all kinds of forms.
Which in some ways is a monstrous amount, and in some ways is really not so much.
Yeah. I mean, we have to remember the total global GDP is in the order of $80 trillion.
So we're talking about less than half a percent. But remember, most of the money that we spend,
we spend on ourselves. So in the US, you spend most of your money on the U.S. But to
the extent that we care about other people around the planet, I think it's great. I would love us to
spend more, but we certainly want to spend whatever we end up spending on the rest of the world in the
best possible way. Right. And give me a sense of how that money breaks down, especially the U.N.,
what the U.N.'s share of that development aid is? Well, the UN is actually not all that much.
Much of this is either given through direct development aid like in USAID and all the
equivalent in the national countries. Then there's some that's given to international
organizations, which you could claim is partly the UN through the World Bank, UNICEF, the others.
And then there's probably in the order of $20 billion that goes into the UN budget itself.
Now, that said, the UN is perhaps of outsized influence, if for no other reason than the
publicity it generates when it decides what's a goal worth going after and what's not.
Yes?
Yes, if they're successful.
Remember, the UN constantly make all these proclamations.
I'm pretty sure you
didn't know that you were living through the International Year of Crystallography.
I did not.
Which the UN has designed this year to be. And it's also the decade for family farming.
So they have a lot of things that they proclaim that don't actually have a lot of influence.
But there's one set of goals that have had an outside influence for the UN, and they're like probably their biggest
success. And that's the ones that are called the Millennium Development Goals, which basically set
out a number of very specific targets from 2000 to 2015 with very specific goals.
Yeah, give us a very brief overview of those.
Well, they ended up being about 18 targets, and really we only remember about nine
of them. So they were half the proportion of people living in poverty, half the proportion
of people starving, get all kids in school, reduce child mortality by two-thirds, maternal mortality
by three-quarters, and get clean drinking water and sanitation to everyone. And those goals worked out how? They have mostly worked out really well. We've spent a lot of money on them, there's been a lot
of focus, and we've reached most of them reasonably well. Now, there's some things,
predictably, you know, getting all kids in school. Well, that was never going to happen,
because you can't get the last kid into school. But we've gone from about eight out of ten kids
going to school to
about nine, a little more than nine kids out of 10. Likewise, we've seen a dramatic drop in poverty.
But again, remember, that's also partly because of China. And of course, that has very little,
if anything, to do with UN proclamations. But we have seen a surprising decline in childhood
mortality. In 1990, when the targets actually
take their starting date, we estimate more than 12 million kids died before their fifth birthday.
Today, that number is below seven. That's probably 6.6. So we've almost halved the proportion of kids
dying. And remember, we actually have slightly higher cohorts. So it's
a phenomenal achievement. But what is problematic is they actually promised two-thirds reduction.
So what most people have heard is, oh, you didn't manage. You didn't make it because we only halved
it. And so that's the risk of setting two ambitious goals that most people have actually heard, oh,
the UN failed. Yes, but we failed on an incredibly
ambitious target and we've actually made an amazing achievement. They need to learn the
trick of corporate finance officers who just re-forecast whenever they need to, right? Instead
of saying it was by two-thirds, say it was by one-third and you get to half and you've succeeded. Coming up on Freakonomics Radio, what is Bjorn Lomborg's group really hoping to achieve?
We like to think of ourselves as constructing a menu for society.
Imagine if you go into a really expensive New York restaurant and you get this wonderful menu, but there are no prices and sizes on it. And one more thing. If you are new to Freakonomics Radio, new-ish, or just habitually
lazy, you may want to subscribe to it on iTunes or wherever you get your podcasts. It is free,
it's easy, and like the finest restaurants, it's all you can eat.
From WNYC, this is Freakonomics Radio.
Here's your host, Stephen Dubner.
Today we're talking with Bjorn Lomborg.
He trained as a political scientist.
Now he teaches at the Copenhagen Business School and he runs a group called the Copenhagen Consensus Center,
which tries to measure the best return on investment for development dollars. We were talking earlier about the United Nations Millennium Development Goals, which were set for completion in 2015.
Nor can anyone deny the progress that has been made toward achieving certain Millennium
Development Goals. The doors of education have been opened to tens of millions of children,
boys and girls.
New cases of HIV-AIDS and malaria and tuberculosis are down.
Access to clean drinking water is up.
Around the world, hundreds of millions of people have been
lifted from extreme poverty.
That is all for the good.
And it's a testimony to the extraordinary work that's been
done both within countries and by the international community.
Yet we must also face the fact that progress towards other goals that were set has not come
nearly fast enough. Now that it's almost 2015, the UN is choosing a new set of development goals to be met by the year 2030.
Lomborg's group applauds the millennial goals, but it's trying to encourage the UN to think about goal setting a bit differently this time around.
There was actually no good cost and benefit analysis.
It was just a number of targets that all sound really good,
and generally I also think they really are very good. But now the UN is going to redo
the targets from 2015 and 15 years onwards. And this time, instead of having a very closed
argument, it was basically a few guys around Kofi Annan who set out these targets back in 2000,
and then everybody adopted them.
This time they have said, we want to hear everybody's input. Of course, that's very laudable,
but not surprisingly, it's also meant that we probably have about 1,400 potential targets
on the table. And so we need to make sure we don't just end up with a whole long list of
Christmas trees, as they call them in the UN jargon.
You know, you just have everything in your wish for all good things,
because they're not likely to be as effective.
Okay, so describe the committee process, the triaging process within the UN, and particularly the open working group, which you've now formed a sort of relationship with.
I'm not sure exactly how to characterize that relationship.
Well, the UN has opened several different fronts.
They've asked the public to come in with their priorities. Almost more than 5 million people have now answered
what they think should be some of the top priorities. But of course, that's more around
problems than around actual solutions. They had a high-level panel, including the prime minister
from Britain and the president from Sierra Leone and Indonesia and a number of other high dignitaries who came
out with their proposal. And then they had the Open Working Group, which is a collection of
70 countries. Remember, the UN has 193 countries, so not everyone has been heard, but they've gone
on for about 16 months meeting very regularly and trying to make their set of goals. The problem is the first set of Millennium Development Goals
essentially had 18 targets.
The high-level panel had 58 targets.
But the open working group, their final document,
came out and had 169 targets.
And so my problem here is if you say you have 169 priorities,
you in reality have none.
And that's why we need to
find a way to make fewer, smarter targets. Okay. So the idea, your idea then is to create a cost
benefit analysis to help an organization like the UN and the Open Working Group decide which
global goals to accept or to set based on cost and reality of achievement and impact. So do you feel that most of the
decision makers in this realm in the UN and related agencies are open to pure cost-benefit
analysis or are they, whether out of habit or incentive, wed to a more traditional political
view? Oh, I think when you talk to them, and I've talked to quite a number of the UN ambassadors
and their staffers, they all love the idea. I mean, when we first went around to them, we told them we were going to do this long process where we
had all these period papers and they would be coming out this fall. And they were like,
this is exciting. Is there any way you could have this done by next week? Was there sort of
original inspiration? That was actually why we did a very rough and ready version where we simply
went through their list and marked it up with
green, yellow, and red colors to indicate whether it was a phenomenal or a good, fair, or poor
target. And I think that was very influential in getting them to think about, oh, wait,
it's not just about what sounds good and what our country has decided, but it's also about cost
and benefits. But of course, let's be realistic. It's not like they're suddenly going to go out and say, oh, oh, we're wrong about that. Well,
we'll go for something else. But the world will spend two and a half trillion dollars
on development aid over the next 15 years. So we're leveraging a huge amount of money.
So if we can just make essentially the UN ditch one bad target and put one more good target in there instead, we could do hundreds of billions of dollars worth of good.
And so we're figuring we're only going to change a little bit.
But because we're leveraging so much, we'll actually end up doing a lot of good.
When I read the 17 major categories that the UN has put forth so far, it strikes me that development goals, what are called development goals, are often very much like macroeconomic goals. So some of them,
at least. So one here is promote sustainable consumption and production patterns, which
sounds a lot like economics, and quote, promote strong, inclusive and sustainable economic growth
and decent work for all. So am I correct to assume that these committees that are working
within the UN are full of economists, or are they not?
My understanding is that they're full of bureaucrats, and they come from a lot of different backgrounds, but they'll probably, a lot of them, be political scientists like myself.
But they'll be much more attuned to what is it that we typically focus on. So we had a good experience, for instance, when I gave a presentation at the UN on our project, and people actually congratulated me afterwards for having done the best seminar
that they'd ever experienced. And I was really flattered until they told me because nobody fell
asleep. But we were talking to the US UN ambassador, and she was very annoyed that we pointed
out one of her favorite targets was not a very good target. And so she said, I really don't like you pointing out that this is a bad target,
but I really need to hear it. And I think that's basically how they feel about it.
Yes, they understand the necessity, but it's politically obviously not always convenient.
What was this target that wasn't so good in your view?
It was the idea that we should have gender disaggregated data.
So the idea is to say if we get more data to support the fact that women get less education, that they get less well paid and so on, it'll actually help stimulate the point of getting more gender equality.
It's a very nice idea.
The problem is our economists tell us we actually have enough data to achieve this.
You know, you speak as though the dynamic between your group and their group is good,
and it is an open working group after all that called for comment from the public,
including yourselves. But I have to say, I would think they hate you. I would think that they sit
around being very high-minded and kind of holistic, and then you come in and say, yeah, that's nice, but let's talk about the real world.
And persuade me that that's not the dynamic.
No, I think you're capturing part of it.
Clearly, their life would be easier if there was no one else commenting from the outside, and it'd certainly be easier if there was nobody marking up some of their text with red. On the other hand, they also want to help the world. They want to
leave a lasting legacy. And they know just saying something that sounds beautiful and looks great
in nicely written documents is not the way to save the world. So I think they appreciate that when we say they're red
for all the other targets, all the ones that their negotiation partners propose, they're like,
yay, that's right. That's what we said. But of course, then when we say one of your own targets
is also pretty poor, yes, then they get a little annoyed. And at the end of the day,
we recognize this is inevitably going to be a discussion that has lots and lots of other parameters.
But if we can push it a little bit towards more efficiency, because we're leveraging $2.5 trillion, we can do a lot of good.
Okay. So, Bjorn, let's get into the findings of your group. report 169 total targets within more than a dozen major categories that range from poverty and
famine to climate change and sustainable industrialization. You ranked more than two
dozen of these targets phenomenal and a slightly smaller number than that, poor, everything else
in the middle. So talk generally just for a moment about what it takes to turn a goal into a phenomenal ranking versus a poor ranking.
Well, there's a number of different things. It has to be very clear and it has to be very
one directional. So you're not trying to achieve things that are really at cross purposes. But then
mostly it needs to be something that we know how to do, and we know how to do fairly cheaply, and it'll do a lot of good.
And unfortunately, a lot of the targets that the UN has set up turns out to be one of those things where you say, oh, all good things for all good people, and we don't quite know how we'll work it out.
And if we try and do it, it'll probably be fairly costly, and it will probably not do as much good. So
that's what defines a poor ranking.
Let's start with food security.
Ending malnutrition in all its forms, including undernutrition, micronutrient deficiencies, and so on.
You said the ending is a bad goal, perhaps, because that's perhaps impossible. But you did rate that phenomenal versus a poor ranking for developing food systems that are more productive, sustainable, resilient, and efficient, and so on.
Talk about the difference between those two, why one is great and why one is really not great.
The first one, and again, if we disregard the end, because we will not be able to end this, but what we should be saying is get down to two or 3% malnourishment, which is both
reachable and actually would be a phenomenal achievement. Where are we now? We're at 13%,
I want to say. So, you know, we could definitely do a lot better. And the reality is we know that
that's very cheap. It's essentially making sure that you get, especially kids, good food for the
first couple of years. And we know how to do that. That's by making sure they get get, especially kids, good food for the first couple of years.
And we know how to do that. That's by making sure they get micronutrients, which is fairly cheap,
and we can distribute it in the health days that are typical across much of Africa and Southeast
Asia. And then we need to have emergency opportunities to get lots of calories to
babies when they're severely underfed, both of which are fairly low cost.
We estimate per child, it's about $96. And the benefits are phenomenal. We know from studies
around the world that if you can get better nutrition to kids, their brain develop more,
they stay longer in school, they learn more. Even if they're in a crappy school, they'll learn a lot
more. And actually, if you avoid being stunted, which is one of the best ways to show that you've been malnourished, you make three times the income
when you become an adult. So basically, you're a much, much more productive person in society.
So we estimate that for every dollar you spend on that very simple way of avoiding malnutrition,
you do about $59 worth of good. Now, the other target you asked about essentially tries to say we should
do all good things. There are some of these things we don't quite know how you would do,
but let me just take the sort of obvious contradiction. On the one hand, you want to
be more environmentally sustainable, which is a great thing, which means putting in less fertilizer,
less pesticides, having less intensive agriculture.
On the other hand, you want to get food enough so that everyone is fed and they're fed cheaply
with good foodstuffs, which typically means you need to put in more fertilizer,
more pesticides, more intensive farming. And so you're essentially asking to do both things.
Now, I'm sure there are some ways that we could actually develop a target
that would still make some sort of balance and actually could be okay, but it's not obvious that
this would be more than okay, and it's very likely that we could end up just simply taking parts of
it and end up making it a pretty poor policy. Let's talk about a couple of education goals,
then. You are in favor. You give a phenomenal ranking to the idea
of increasing the proportion of kids who are able to access and complete pre-primary education. Do
you want to talk for just a second about the returns to that? Again, I should just say it's
not me who is saying this. We asked 32 of the world's top economists across all these different
areas, and this is their evaluation. So it's not because I'm sitting here and saying, I think this
or that. Fair enough. Thank you.
But the economists that looked at education actually shows that we have managed to get
most kids into primary education, but there's a lot of kids that don't go to pre-primary education,
preschool. Partly, it's very cheap because you don't need all that much qualifications to teach.
It's very easy to get kids in there because
they don't really compete with anything else. The parents are not saying, oh, but you could
make a living wage instead. And they are also much more open to having girls especially go to
these preschools. So we can do something that's cheap. And we actually know that this leaves
lasting effects in being able to better educate yourself also in the future, even if you
don't get a formal education. So we estimate that the benefits are in the 30s. So probably
for every dollar spent, you do $33 worth of good. Now, is this a true number? Of course it's not.
It's an estimate, but it gives you an indication that this is probably one of those places where
you'd get excellent return on your dollar.
Okay, so big return on pre-primary education. What about post-secondary, college and so on?
Yeah, the problem is the way it's formulated, they want to promise, and this is typical for these sorts of documents, they want to promise everybody to be able to get into, for instance,
university. It's a beautiful idea, but the problem is for most countries,
it ends up being a way to subsidize rich people's kids to go to college. If you make college free,
because most of the attendees at universities are from the high classes, that is effectively
a subsidy to rich people's kids. Instead, what you should be doing is if you want to get more
poor kids into a college, you should be giving them scholarships. That's kids. Instead, what you should be doing is if you want to get more poor kids into
college, you should be giving them scholarships. That's a much cheaper, much more directed way
to make sure that you get a better socioeconomic profile in college. But let's not kid ourselves.
This is not what makes productivity dramatically rise in the first 30 or 50 years of development.
That's much more about getting everyone educated
so they can read and write.
Let me ask you about a phenomenal and a poor ranking
the Copenhagen Consensus Center has given
for two goals in the climate change arena.
Phenomenal mark goes to the proposal to quote,
by 2030, phase out inefficient fossil fuel subsidies,
but a poor mark to the proposal to, quote,
double the share of renewable energy in the global energy mix by 2030. At first blush,
those might seem to be contradictory. Explain why one gets phenomenal, the other poor?
Most people, when you talk about it, certainly when we're reaching out to an American audience,
will think that fossil fuel subsidies are something of the first world.
It's actually not. By far, the majority of fossil fuel subsidies come in third world countries,
where many countries are subsidizing their basic provisions like bread and also gasoline as a way
to keep their population quiet. Iran spends almost $75 billion, which is a huge proportion of their national budget.
Likewise with Egypt, some of the other big ones are Russia, China, India, Saudi Arabia. And that
actually helps destabilize anything else those powers can do because fundamentally they can't
afford to provide, for instance, better healthcare or better education and many of the other things
because they're spending a huge amount of their resources on fossil fuel subsidies.
Of course, they're also at the same time encouraging overuse of fossil fuels and
thereby more emissions of CO2. And also, of course, if you, for instance, subsidize gasoline,
you're basically helping people who can afford a car, which will typically be the rich people.
So in reality, cutting these subsidies has benefits on all those different accounts and
will probably leave the state much better able to do the things that it should actually be focusing
on, namely, for instance, education and health and so on. When you talk about getting more green
energy, it's something a lot of us in the rich West like. We want to have more solar panels
and wind turbines. The problem is, for most people in the poor world, it's about getting access to
electricity. And that access is mostly, not always, but mostly much cheaper with fossil fuels.
There's an estimation from the Center for Global Development in D.C. that looked at, you know,
Obama has pledged to help electrify Africa. And the U.S. is probably going to spend about $10 billion doing so. That's
very wonderful. But if you spend it, which Obama will probably do, mostly on renewables,
they estimate you can help about 20 million people come out of darkness and hence poverty.
But if you spent the same $10 billion on gas, you could lift 90 million people out of darkness and hence poverty. But if you spent the same $10 billion on gas,
you could lift 90 million people out of darkness and poverty. So the fundamental point here is to
say you can do much, much better. And so unless you are very careful with your subsidies to green
energy, you'll actually end up doing pretty poorly and very likely actually less than $1 back in the
dollar. There's one set of numbers here that is so astonishing, I just want to run them by you
and ask you to briefly comment.
The costs associated with domestic violence are over an order of magnitude higher than
the costs of civil war.
290 million kids are beaten every month at a cost of $8 trillion compared to the $170
billion cost of civil wars.
Yeah, it's a great outcome of a study. And this is the first time they put numbers to what's the
cost of domestic violence. And clearly, this is only an approximate number. It basically takes
what's the cost of an assault in the U.S. and then scale it so that, you know, if you only make one
tenth of what the U.S. makes, the cost of
that assault is also one-tenth. But even then, because there's so many kids, as you mentioned,
290 million kids that are abused each month, and there's almost as many women that are abused
every year, it's a much, much bigger number. Even though all our TV overflows with Syria and Iraq. And this is
definitely serious issues. It's actually much less so than the problem of domestic violence.
So it's both women and kids that sum up to $8 trillion or about 9% of global GDP.
All right. Let me ask you this then. Economists have a saying they like. They'll say that,
oh, that sounds great in practice,
but does it work in theory? Right. And that's because economists love theory and analysis and
math. All of that is often much more elegant than the real world. Wooly as it is, will allow. So
let me ask you the opposite. What you're doing by constructing a cost benefit analysis of these
development goals, it sounds great in theory,
but what about in practice? How do you translate what you've learned to the real world and make it actionable, make it worthwhile? In other words, is anyone going to listen to you and act on it?
Well, I think a lot of people are listening, as we talked about before. We're not the only input
to this conversation, but if we're just part of that input, it becomes harder to ignore really, really great opportunities and becomes harder to ignore that
some of the proposed targets are not very good. We like to think of ourselves as constructing a
menu for society. Imagine if you go into a really expensive New York restaurant and you get this
wonderful menu, but there are no prices and sizes on it. Unless you have a very good expense account, you're going to feel a little uncomfortable ordering.
But what we try to do is we put prices and sizes on those different menu points.
Now, that doesn't mean that the champagne or the caviar might not be your first choice anyway.
But at least now you'll know that you can afford less for dessert.
So in some sense, what we try to do is we give people a sense
of proportion. Now, this is not the only thing they're going to use, but if they'll just use a
little bit of it, chances are we'll end up with a slightly less inefficient, if you will, outcome.
And that's still great. Hey, podcast listeners.
America is one of the most generous nations in the world,
maybe in the history of
the world. On next week's show, what really makes people give and how can we get them to give more?
Beautiful women ended up raising the most money of all the solicitors that we had.
This entire physical attractiveness result is driven by men answering the door they say oh
tell me more about this relief fund tell me how i can help oh i'd love to help
you just can't beat a beautiful blonde who's going door to door to raise money for your cause
the science of fundraising that's next time ononomics Radio. And don't forget what we talked about earlier.
