- [Tyler] Once you master
the economic way of thinking,
-
you'll see the world
in a very different way.
-
Two fundamental economic concepts
are everywhere you look --
-
opportunity cost,
-
and tradeoffs.
-
Let's start with opportunity cost.
-
At this busy coffee shop,
-
opportunity costs lie
behind every decision.
-
Like for Jenny -- she's here
for her third date with Adam.
-
Was that a good decision?
-
After all, economics is
all about studying decisions.
-
Making a good decision is
about comparing the benefits
-
of that decision to the costs.
-
The obvious costs for this date,
-
for Jenny, were the Uber ride
she paid for to get here,
-
and her grande chai tea latte
with whole milk.
-
But what's missing?
-
Her opportunity cost.
-
Opportunity cost means the value
of the next best alternative.
-
For instance, instead of going
on her third date with Adam,
-
Jenny could've been binge watching
her favorite tv show.
-
She might've been
on a first date instead,
-
with Roman.
-
Or she might've been
having breakfast
-
with her very sweet sister.
-
Let's say her next best option
-
would've been
breakfast with her sister.
-
Does the benefit
of this third date with Adam
-
outweigh the opportunity cost?
-
It might seem strange
to think this way about romance,
-
and it doesn't mean that it's
about calculating every decision
-
down to the last penny.
-
Nonetheless, Jenny's time,
attention and energy --
-
those are scarce.
-
And if she doesn't consider
the alternatives at all,
-
she might be wasting
parts of her life.
-
There's another
fundamental related concept
-
from economics -- tradeoffs.
-
Take these sprinklers
in the ceiling of the coffee shop,
-
for example.
-
Adding sprinklers can
make it safer during a fire,
-
but they also can cost
a lot of money to install.
-
How much cheaper would
the coffee be without them?
-
In a world of scarce resources,
one typically has to choose.
-
There's a tradeoff --
safer buildings cost more,
-
but that means the coffee can
be more expensive.
-
The line is out the door here.
-
Perhaps the owner has considered
opening a second location.
-
As the building code, however,
becomes more stringent,
-
the cost of opening
an additional location goes up.
-
It's not just the direct
monetary costs of paying
-
for things like sprinklers.
-
It's also the opportunity costs
of the extra time and effort
-
to file permits, manage the work
and schedule inspections.
-
A more stringent building code
means a higher cost
-
for opening up new businesses.
-
And in turn,
that higher cost can mean
-
that fewer new businesses
get opened.
-
What's the right tradeoff
between making buildings safer...
-
and making it easier
to launch new businesses?
-
Once you see these tradeoffs,
-
you'll find them
everywhere you look --
-
healthcare,
-
food,
-
the environment.
-
education.
-
One more decision to consider --
-
if you're a teacher,
should you spice up
-
your economics class
by checking out our free unit plan
-
that uses this video?
-
If you're a learner,
should you watch another MRU video?
-
Well, YouTube is full
of entertaining videos,
-
[cat meows]
-
but please, of course, consider
the opportunity costs.
