which are two things that a lot of us spend a lot of our time thinking about.

Either trying to earn them or trying to increase them.

And a lot of us resonate with this phrase,

so we see it in religions and self-help books,

that money can't buy happiness.

And I want to suggest today that in fact that's wrong.

(Laughter)

I'm at a business school, so that's what we do. So that's wrong.

And in fact, it's not so much that money can't buy happiness.

(Laughter) (Applause)

It is not so much that money can't buy happiness,

it's that If you think that, you're just not spending it right.

So that instead of spending it the way you usually spend it,

maybe if you spent it differently that might work a little bit better.

Before I tell you the ways that you can spend it that will make you happier,

let's think about the ways we usually spend it

that don't in fact make us happier.

We had a little natural experiment.

CNN a little while ago, wrote this interesting article

on what happens to people when they win the lottery.

People think when they win the lottery, their lives are going to be amazing.

This article is about how their lives get ruined.

So, what happens when people win the lottery:

1) They spend all the money and go into debt

2) All of their friends and everyone they've ever met,

find them and bug them for money.

It ruins their social relationships in fact.

They have more debt and worse friendships than they had before they won the lottery.

What was interesting, people started commenting

on the article, readers of the thing.

Instead of talking about how it had made them realize

money doesn't lead to happiness,

everyone was saying: "You know what I would do if I won the lottery?",

fantasizing about what they'd do.

Here are just two of the ones we saw, that are interesting to think about.

One person wrote: "When I win I'm going to buy my own little mountain

and have a little house on top".

(Laughter)

Another person wrote:

"I would fill a bath tub with money and get in the tub

while smoking a big fat cigar

and sipping a glass of champagne". This is even worse now.

"Then I'd have a picture taken and dozens of glossies made.

Anyone begging for money or trying to extort from me

would received a copy of the picture and nothing else".

(Laughter)

And so many of the comments were exactly of this type.

Where people got money and in fact it made them antisocial.

I told you that it ruins people's lives and that their friends bug them,

it also makes us feel very selfish and we do things only for ourselves.

Maybe the reason why money doesn't make us happy

is that we're always spending it on the wrong things.

In particular, we're always spending it on ourselves.

And we thought, what would happen

if we made people spend more money on other people?

So, instead of being antisocial with your money

what if you're a bit more prosocial with your money

and we thought let's make people do it and see what happens.

Let's have some people do what they usually do

and spend money on themselves,

and let's make some people give money away,

measure their happiness and see if in fact they get happier.

The first way we did this, on one Vancouver morning,

we went on a campus at University of British Columbia.

We approached people and said: "Do you want to be in an experiment?"

If they said yes, we asked them how happy they were,

and then we gave them an envelope.

One of the envelopes had things in it that said:

"By 5 p.m. today spend this money on yourself".

We gave some examples of what you can spend it on.

Other people in the morning got a slip of paper that said

by 5 p.m. today to spend this money on somebody else.

Also, inside the envelope was money. We manipulated how much we gave them.

So, some people got this slip of paper and 5 dollars.

Some people got the slip of paper and 20 dollars.

We let them go about their day. They did whatever they wanted to do.

We found out that they did spend it the way we asked them to.

We called them up at night and asked:

"What did you spend it on and how happy do you feel now?"

Well, these are college undergrads, a lot of what they spent it on for themselves

was things like earrings and make up. Apparently, some of them were women.

What about for other people? Very different things.

One woman said she bought a stuffed animal for her niece.

People gave money to homeless people.

Huge effect here of Starbucks.

(Laughter)

If you give undergraduates 5 dollars, it looks like coffee to them

and they run over to Starbucks and spend it as fast as they can.

Some people bought a coffee for themselves,

the way they usually would,

but other people said that they bought a coffee for somebody else.

So, the very same purchase,

just targeted towards yourself or towards somebody else.

What did we find when we called them back at the end of the day?

People who spent money on others got happier.

People who spent it on themselves, nothing happened.

It didn't make them less happy, it just didn't do much for them.

The other thing we saw, is that the amount of money doesn't matter much.

So, people thought that 20$ would be way better than 5$.

In fact, it doesn't matter how much money you spend,

what really matters is that you spend it on somebody else rather than on yourself.

We see this again and again when we give people money

to spend on other people instead of on themselves.

These are undergraduates in Canada -

not the world's most representative population.

They're also fairly wealthy, affluent and all these sorts of things.

We wanted to see if this holds true everywhere in the world

or just among wealthy countries.

So we went to Uganda and ran a very similar experiment.

Imagine instead of being in Canada, where we would say to people:

"Name the last time you spent money on yourself or other people?

Describe it, how happy did it make you?"

Or in Uganda: "Name the last time you spent money

on yourself or other people and describe that".

Then we ask them how happy they are.

Again, what we see is amazing because there are human universals

on what you do with your money,

and real cultural differences on what you do, as well.

For example, these are some similarities.

These are two gentlemen from Canada and Uganda.

Here is one guy from Uganda, who says this.

We said: "Name a time you spent money on somebody else."

Men frequently talk about spending money on women, as it turns out.

He said: "I called a girl I wished to love."

I think he means romantically love, though it's unclear

if he means physical love.

"We went out on a date...".

At the end he says that he didn't achieve her until now.

Here is a guy from Canada, very similar thing.

"I took my girlfriend out for dinner. We went to a movie. We left early.

Then went back to her room for only cake".

(Laughter)

Human universal: you spend money on other people,

you're being nice to them.

Maybe you've something in mind, maybe not.

But then we see these similarities,

but also extraordinary differences.

Look at these two. This is a woman from Canada.

We say: "Name a time when you spent money on somebody else".

She says: "I bought a present for my mom.

I drove to the mall, bought a present and gave it to my mom".

Perfectly nice thing to do. It's good to get gifts for people you know.

Compare that to this woman from Uganda.

"I was walking and met a long time friend whose son was sick with malaria.

They had no money. They went to a clinic and I gave her this money".

This isn't 10000$, it's the local currency. It is a very small amount of money, in fact.

Enormously different motivations.

This is a real medical need, literally a life-saving donation.

Above, it's just kind of, "I bought a gift for my mother".

What we see again is that the specific way that you spend on other people

isn't nearly as important as the fact that you spend on other people

in order to make yourself happy, which is really quite important.

You don't have to do amazing things with your money to make yourself happy.

You can do small trivial things and yet still get benefits from doing this.

These are only two countries.

We wanted to go broader and look at every country in the world if we could,

to see what the relationship is between money and happiness.

I'll show you a world map in a second. We got data from the Gallup Organization,

which you know from the political polls that have been happening lately.

They ask people: "Did you donate money to charity recently?"

"How happy are you with your life in general?"

We can see what the relationship is between those two things.

Are they positively correlated?

Giving money makes you happy? Or, they're negatively correlated?

On this map, green means they're positively correlated,

red means they're negatively correlated.

You can see the world is crazily green.

In almost every country in the world, where we have this data,

people who would give money to charity, are happier than people

who don't give money to charity.

I know you're all looking at that red country in the middle.

I'd be a jerk and not tell you what it is. It's Central African Republic.

You can make up stories, maybe it's different there for some reason.

Just below that to the right is Rwanda which is amazingly green.

So, almost everywhere we look, we see that giving money away

makes you happier than keeping it for yourself.

Across the world we see this in your everyday life

that this is the impact of spending money on others rather than yourself.

But this is your own everyday life, and sometimes you personal life.

What about our work life, where we spend all the rest of our time

when we're not with the people we know.

We decided to infiltrate companies and do a very similar thing.

These are sales teams in Belgium. They work in teams,

they go out and sell to doctors and try to get them to buy drugs.

We can look at how well they sell things as a function of being a member of a team.

For some teams we give people some money for themselves,

and say: "Spend it however you want on yourself".

Just like we did with the undergrads in Canada.

But to other teams we say: "Here's 15 euros.

Spend it on one of your teammates.

Buy them something as a present and give it to them.

Now we got teams that spend on themselves

and we have these prosocial teams who we give money

to make the team a little better.

The reason I have a ridiculous pinata there,

is one of the teams pooled their money and bought a pinata.

They got together, smashed the pinata and all the candy fell out.

A very silly and trivial thing to do,

but think of the difference on the team that didn't do that at all

that got 15 euro, put it in their pocket, maybe bought themselves a coffee.

Or teams which had this prosocial experience

where they all bonded together to buy something and do a group activity.

What we see is that the teams that are prosocial sell more stuff

than the teams that only got money for themselves.

One way to think about it is for every 15 euro

you give people for themselves,

they put it in their pocket and don't do anything different than before.

You don't get any money from that. You actually lose money

because it doesn't motivate them to perform better.

But when you give them 15 euro to spend on teammates,

they do so much better on their teams that you get a huge win

on investing this kind of money.

You're probably thinking to yourselves, "This is all fine, but there is a context,

that is incredibly important for public policy,
