PROFESSOR: So what I want to
do today is I want to talk

What are you going to be
learning in this course?

And just, sort of, set us
up for the semester.

So basically, microeconomics
is all about scarcity.

It's all about how individuals
and firms make decisions given

Scarcity is key because
basically what we're going to

learn about this semester in
various shapes and forms is a

lot of different types of
constrained optimization.

We're going to learn a lot
about different ways that

individuals make choices
in a world of scarcity.

That is, this course is going
to be about trade-offs.

Given scarce resources, how
the individuals and firms

That's why economics is called
the dismal science.

It's called the dismal science
because we are not about

We're always the people who
say, no, you can't have

Because that's why we're called
the dismal science,

Now, some may call it dismal,
but I call it fun.

And that may be because of my
MIT training, as I said I was

In fact, MIT is the perfect
place to teach microeconomics

because this whole institute is
about engineering solutions

which are really ultimately
about constrained

You're given a pile of junk,
you've got to build something

That's an exercise in
constrained optimization.

All engineering is really
constrained optimization.

How do you take the resources
you're given and do the best

And that's really what
microeconomics is.

Just like 270 is not a dismal
contest, microeconomics is not

But instead of the building
robots, we're

Instead of trying to decide how
we can build something to

move a ping pong ball across a
table, we're trying to decide

how people make their decisions
to consume, and

That's basically what's going
to go on in this class.

And that's why basically modern
microeconomics was

founded at MIT in the 1950s
by Paul Samuelson.

The father of modern economics
was a professor here, and he

He basically introduced
mathematics to economics.

And through teaching this
course, 14.01, 50, 60 years

ago, actually developed the
field that we now study.

Now, what we're going to do in
this class, is focused on two

And we are going to build models
of how consumers and

producers behave. Now,
technically, a model is going

to be a description of any
relationship between two or

A description of any
relationship between two or

The trick with economics, and
the reason many of you will be

frustrated during the semester,
is that unlike the

modern relationship between
say energy and mass these

They are never accurate
to the 10th decimal.

We'll be making a number of
simplifying assumptions that

allow us to capture the main
tendencies in the data.
