Description:
What is the Double Coincidence of Wants? When currency becomes unacceptable as a transaction tool of value, societies often resort to barter, as in the case of Venezuela and previously, in Greece. The problem is often in negotiating an equivalence in perceived value between disparate commodities and their respective quantities. The double coincidence of wants is the serendipitous event where each party has exactly what the other requires to enact and close a successful barter.

an economist would describe flirting you know right before she

grabs a supply curve of swipe right were the dates

on tinder But the term has a totally different non
- 00:26
romance related meaning for economists It refers to the very
- 00:30
limited conditions that have to exist in order for bartering
- 00:33
to work well in most basic terms the double coincidence
- 00:38
of wants describes the rare situation where two parties each
- 00:41
have something the other wants And both are willing to
- 00:45
make the exchange the perfect barter situation right Okay so
- 00:49
flee Bartering like this guy Different parts Bartering is when
- 00:53
you trade a good or a service directly for another
- 00:56
good or service You agreed to mow your neighbor's lawn
- 00:59
if well she'll bake you some of her special oatmeal
- 01:02
chocolate chip cookies That's barter It doesn't happen very much
- 01:06
in modern economies mostly because well we skip the bother
- 01:09
and just use money well Nowadays when you want to
- 01:11
buy something you typically use what's called a medium of
- 01:15
exchange and specifically well you use money At least in
- 01:17
America you do currency representing a value the worth of
- 01:21
which everyone generally agrees upon You go to the store
- 01:24
pick up a pint of double chunky Chako marshmallow fudge
- 01:28
ice cream You hand over the cash and the treat
- 01:30
is yours if you don't have cash on you or
- 01:33
if you're buying your double chunky Chako marshmallow fudge online
- 01:37
while delivered next day via drone inconvenient dry ice Amazon
- 01:41
packaging Well you can use some kind of cash equivalent
- 01:44
like a credit card or a PayPal account thing You're
- 01:47
venmo or apple pay or something like that The point
- 01:49
is you can use some sort of currency The currency
- 01:52
represents a medium of exchange right It is a medium
- 01:56
itself and you agree on the number of units of
- 01:59
that currents to make the exchange affair on both sides
- 02:02
released Acceptable It can be used in any commercial venture
- 02:05
because well everyone will take it instead of directly trading
- 02:08
goods and services that goods and services can be traded
- 02:10
for the medium of exchange which can then be used
- 02:13
to get other goods and services right It's called liquidity
- 02:16
Essentially its financial liquidity and dollars are trusted as a
- 02:20
medium of exchange so they're the most liquid currency in
- 02:23
the country Well that's how things work in the modern
- 02:25
economy Anyway You trade some medium of exchange that is
- 02:28
you use money to buy what you need Okay so
- 02:30
a bunch of aliens appear out of nowhere They blast
- 02:33
the earth with nuclear destruct O raise jazz for target
- 02:36
practice Thanks guys Then they fly off to blow up
- 02:39
some stuff nearer Alfa Centauri Yeah Most of the world's
- 02:42
destroyed civilization has fallen apart People wander the destruct O
- 02:46
scarred wasteland in small warring bands There are no more
- 02:50
Treasury Department's No more central banks no more paper towels
- 02:53
no more credit cards or Apple pays no more money
- 02:56
at all No medium of exchange whatsoever If the roving
- 03:00
post apocalyptic tribes wanna trade for something well they need
- 03:04
barter Here's where that double coincidence of wants then comes
- 03:08
into play right It's a coincidental that both sides double
- 03:12
of them want the same thing If you want a
- 03:15
pint of double chunky chocolate marshmallow fudge Well you can't
- 03:18
just stroll down to the store and pick it up
- 03:20
Instead you first have to find someone who will dwell
- 03:23
among the starving remnants of humankind Still makes premium specialty
- 03:27
ice cream That search represents the first want in the
- 03:31
double coincidence of wants You want the double chunky chako
- 03:35
marshmallow fudge You find someone who keeps alive the nearly
- 03:39
forgotten art of double chunky production But to get it
- 03:42
from them you have to have something they want That's
- 03:44
the second one In the double coincidence of once you
- 03:48
need to have something that they want at the same
- 03:50
time that they have something that you want You getting
- 03:53
all this Well all you have are a couple of
- 03:55
knives Cem tattered rags and a few pieces of dried
- 03:58
rat Well to get the ice cream the other guy
- 04:00
had better want a knife set Born up close aren't
- 04:03
nearly inedible chunks of salted vermin Otherwise no deal no
- 04:07
barter Nothing happens well to barter than each party has
- 04:10
to have something the everyone wants That's a double coincidence
- 04:12
of wants There has to be a coincidence of both
- 04:14
people wanting something that the other person has at that
- 04:17
time But it makes bartering inefficient That hold double coincidence
- 04:20
thing is rare a lot rarer than when people have
- 04:23
the amount of dollar bills in their pockets to just
- 04:25
go buy stuff Using a medium of exchange works much
- 04:27
better because you don't need to actually find someone who
- 04:30
wants what you have to offer like that physical good
- 04:32
You just trade what you have for money and then
- 04:35
they use that money to get what they want So
- 04:38
you teach people to speak Albanian You want some Chinese
- 04:41
food for dinner In the barter system you have to
- 04:43
find someone who makes Chinese food and who also would
- 04:46
like to learn Albanian Yeah double coincidence of wants or
- 04:49
you have to go through a complicated series of transactions
- 04:52
to get what you want You teach Albanian to a
- 04:54
person who makes key chains They give you some key
- 04:56
chains for your trouble You trade a few key chains
- 04:59
to someone who owns an orchard for a few bags
- 05:01
of apples You then take those apples to the Chinese
- 05:04
restaurant for a plate of chow mein You have to
- 05:06
spend all day figuring out a series of transactions that
- 05:09
gets you from Albanian lessons to Chinese dinner Money cuts
- 05:12
through this process you don't need the double coincidence of
- 05:15
wants for transactions that happened Just one want at a
- 05:18
time plus some cash at least until the trigger Happy 00:05:21.713 --> [endTime] space travelers show up Roman Everything's over Yeah
