what products they buy like what they choose and then
- 00:21
care about and or what they're indifferent to Well the
- 00:23
indifference curves graphs a choice between two products except well
- 00:27
you just don't care what combination of the products you
- 00:30
get You like the choice is equally when combined you
- 00:33
would take a bunch of different combos and not notice
- 00:36
the difference in value to you lungs You have that
- 00:39
combo or bundle The total doesn't really matter to your
- 00:43
indifferent to it right So not satisfied with a simple
- 00:46
shrug emoji economists have decided this kind of indifference requires
- 00:50
mathematical rigor and a graphing calculator hints thie indifference curve
- 00:54
and indifference Curve is a graph It shows the Siri's
- 00:56
of combinations of goods So here we go Example time
- 01:02
once again no one invited you out this Friday night
- 01:05
So you're gonna go to the store and buy snacks
- 01:07
for your lonely Netflix binge Best You're going to go
- 01:11
buy some bags of caramel corn and a bunch of
- 01:13
packages of Twizzlers You graff your choices on an indifference
- 01:16
curve Each point on the curve represents a combination of
- 01:20
the volume of each of these sugary delights that makes
- 01:23
you equally happy Well the X axis represents an amount
- 01:26
of caramel corn The Y axis represents an amount of
- 01:29
Twizzlers The curve consists of all the possible combos of
- 01:32
two goods that you find equally app healing It's the
- 01:35
line of Well I don't care You have no preference
- 01:38
about the points on that line All the same Completely
- 01:41
indifferent So three bags of caramel corn and two packs
- 01:44
of Twizzlers mean the same to you as two bags
- 01:47
of caramel corn and four packs of Twizzlers your indifferent
- 01:50
or one bag of caramel corn and six packs of
- 01:52
Twizzlers You're indifferent Or maybe you'll just get eight packs
- 01:56
of Twizzlers and skip the caramel corn altogether You'll get
- 01:59
none of it You're indifferent All of these packages mean
- 02:02
the same to you Same value Same You know food
- 02:05
is love and happiness kind of vibe Pull out some
- 02:08
graphing paper while you're standing in the aisle of the
- 02:10
convenience store Ignore the strange looks you get Yes we
- 02:12
do that all the time Grafting indifference Curve on the
- 02:15
curve Measures utility the amount of value you get out
- 02:18
of the combo twizzlers and caramel corn A point above
- 02:20
the curve is more utility So five bags of caramel
- 02:23
corn and seven packages of Twizzlers Well much better You
- 02:26
Khun Binge all night and into tomorrow but that's off
- 02:29
of that indifference curve A point below the curve is
- 02:32
less utility or less value to you One bag of
- 02:35
caramel corn in one bag of Twizzlers Yeah not enough
- 02:38
to get you through a single episode of House hunters
- 02:40
much less utility or value They're not enough for the
- 02:43
amount of Netflix you'll be binging upon but everything along
- 02:46
the curve provides the adequate utility for what you're trying
- 02:48
to do Enough food to get you through your sad
- 02:51
Friday night of Netflix ng all the points on the
- 02:54
curve providing the same amount of utility or value so
- 02:57
How do you decide What combo Tobi Well if all
- 03:00
the combinations are the same to you how do you
- 03:02
choose which valuer Which combo value to go with And
- 03:05
why are we doing this all again anyway Why graff
- 03:08
your indifference Well the best way to use an indifference
- 03:10
curve is to combine it with a budget constraint line
- 03:14
A budget constraint represents the combinations of the two products
- 03:17
for which you have enough money to buy Set another
- 03:20
way Graphing A budget constraint between two items shows all
- 03:23
the possible combinations that you can afford But once you
- 03:26
get to the store you see what a package of
- 03:28
caramel corn is A three dollars fifty cents There all
- 03:31
the package Twizzlers is on sale for a buck You've
- 03:33
got ten dollars in your pocket so check the points
- 03:36
on your indifference Curve Three bags of caramel corn and
- 03:39
two packs of Twizzlers would cost you twelve fifty Yeah
- 03:41
you don't have that's more than your budget Two packs
- 03:43
a caramel corn in four bags of Twizzlers When that
- 03:46
costs eleven dollars it's a buck too much but one
- 03:49
bag Caramel corn and six packs of Twizzlers Well that's
- 03:51
nine fifty It's under your ten dollars budget and I
- 03:54
guess that's what you'll buy Well on a graph you
- 03:56
figure out the indifference curve all combinations that bring you
- 03:59
equal value All these things are all equal to you
- 04:02
in value And then you figure out your budget constraint
- 04:05
curve all the combinations that you can afford to buy
- 04:08
Well the point where the budget constraint line or restraint
- 04:11
line meets the indifference Curve Boom That's the sweet spot
- 04:14
That combo is the one to buy right here Now
- 04:18
you just have to pick what you want to watch
- 04:20
Another indifference curve sets in as you scroll endlessly through
- 04:23
York Netflix options there Yeah you've got a rough life 00:04:26.423 --> [endTime] there Well you could just chill Yeah
