Interest and debt
Compound interest basics
Interest is the basis of modern capital markets. Depending on
whether you are lending or borrowing, it can be viewed as a return on an
asset (lending) or the cost of capital (borrowing).
This tutorial gives an introduction to this fundamental concept,
including what it means to compound. It also gives a rule of thumb that
might make it easy to do some rough interest calculations in your head.
Interest basics
This is a good introduction to the basic concept of interest. We
will warn you that it is an older video so Sal's sound and handwriting
weren't quite up to snuff then.
Credit cards and loans
Most of us have borrowed to buy something. Credit cards, in
particular, can be quite convenient (but dangerous if not used in
moderation).
This tutorial explains credit card interest, how credit card companies
make money and a far more silly way of borrowing money called "payday"
loans.
Continuous compound interest and e
This is an older tutorial (notice the low-res, bad handwriting)
about one of the coolest numbers in reality and how it falls out of our
innate desire to compound interest continuously.
Present value
If you gladly pay for a hamburger on Tuesday for a hamburger
today, is it equivalent to paying for it today?
A reasonable argument can be made that most everything in finance really
boils down to "present value". So pay attention to this tutorial.
Personal bankruptcy
Back in the day (like medieval Europe), you would actually be
thrown in jail if you couldn't pay your debts (debtor's prison). That
seemed like a pretty awful thing to do (not to mention that lenders are
much less likely to be paid by someone rotting in prison), so
governments created an "out" called bankruptcy (which, as you'll see, is
a pseudo-painful "reset" button on your finances).

Housing
Home equity and personal balance sheets
This old and badly drawn tutorial covers a topic essential to
anyone planning to not live in the woods -- your personal balance sheet.
Since homes are usually the biggest part of these personal balance
sheets, we cover that too.
Mortgages
Most people buying a home need a mortgage to do so. This tutorial
explains what a mortgage is and then actually does some math to figure
out what your payments are (the last video is quite mathy so consider it
optional).
Renting vs. buying a home
Is it always better to buy than rent? What if home prices go up
dramatically and rents don't? How can we compare home prices to rents
to figure out what to do.
This older tutorial (low-res, bad handwriting) walks us through this.
It is about housing but similar thinking can be applied to any
rent-vs-buy decision (spoiler alert, Sal did eventually buy a home).
Housing price conundrum
Back before the 2008 credit crisis, Sal was perplexed by why
housing prices were going up so fast and theorized that it was a bubble
forming (he was right).
These pre-2008 videos are fun from a historical point-of-view since they
were made before all the poo poo hit the fan.
Credit Crisis
This tutorial talks about how the housing-bubble-induced credit
crisis unfolded with a focus on the derivative securities that helped
pump the bubble.

Paulson Bailout
In the fall of 2008, it became clear that a cascade of bank
failures was happening because of shoddy loans and exotic securities
(both which fueled a now popping housing bubble). In an attempt to
avoid a depression, the Treasury Secretary (Hank Paulson) wanted to pour
$1 Trillion into the same banks that had created the mess.
This tutorial walks us through the beginnings of the mess and possible
solutions. Historical note: it was created as the crisis was unfolding.

Investment and consumption
When are you using capital to create more things (investment) vs.
for consumption (we all need to consume a bit to be happy). When you do
invest, how do you compare risk to return? Can capital include human
abilities?

Inflation
Inflation basics
$1 went a lot further in 1900 than today (you could probably buy a
good meal for the family for $1 back then). Why? And how to we
measure how-more-expensive-things-have-gotten (i.e., inflation)?
Inflation scenarios
You know about inflation, but now want to look at how thing might
play out in different scenarios. This tutorial focuses on when
inflation is "acceptable" and when it isn't (and the causes and
repercussions).
Real and nominal return
If the value of money is constantly changing, can we compare
investment return in the future or past to that earned in the present?
This tutorial focuses on how to do this (another good tutorial to watch
is the one on "present value").
Capacity utilization and inflation
This tutorial starts with a very "micro" view of when firms decide
to raise (or lower prices). It then jumps back to the macro view to
discuss how capacity utilization can impact prices.
Deflation
Prices don't always go up. They often go down. This might seem
like a good thing, but it could be disastrous for a modern economy is it
goes too far. This tutorial explains what deflation is, how it happens
and what the effects of it might be.

Taxes
Personal taxes
Benjamin Franklin (and several other writers/philosophers) tells
us that "In this world nothing can be said to be certain, except death
and taxes." He's right.
This tutorial focus on personal income tax. Very important to watch if
you ever plan on earning money (some of which the government will take
for itself).

Corporate taxation
In exchange for being treated as a person-like-legal entity (and
the limited liability this gives for its owners), most corporations pay
taxes. This tutorial focuses on what corporations are, "double
taxation" and a few ways that multinationals might try to get out of
paying taxes.

Accounting and financial statements
Cash versus accrual accounting
Just keeping track of cash that goes in and out of a business
doesn't always reflect what's going on. This tutorial compares cash and
accrual accounting. Very valuable if you ever plan on starting or
investing in any type of business (you might also discover a nascent
passion for accounting)!
Three core financial statements
Corporations use three financial statements to report what's going
on: balance sheets, cash flow statements and income statements. They
can be derived from each other and each give a valuable lens on the
operations and condition of a business.
After you know the basics of accrual accounting (available in another
tutorial), this tutorial will give you tools you need to responsibly
understand any business.
Depreciation and amortization
How do you account for things that get "used up" or a cost that
should be spread over time. This tutorial has your answer.
Depreciation and amortization might sound fancy, but you'll hopefully
find them to be quite understandable.

Stocks and bonds
Introduction to stocks
Many people own stocks, but, unfortunately, most of them don't
really understand what they own. This tutorial will keep you from being
one of those people (not keep you from owning stock, but keep you from
being ignorant about your investments).
Shorting stock
Can you sell something that you borrowed from someone else? Why,
yes, you can and it is called "shorting". Why would you do this? Well,
you can now make money if the price goes down. Is this bad? This
tutorial has your answers.
Understanding company statements and capital structure
If you understand what a stock is (also a good idea to look at the
topic on accounting and financial statements), then you're ready to dig
in a bit on a company's actual financials.
This tutorial does this to help you understand what the price of a
company really is.
Corporate metrics and valuation
Life is full of people who will try to convince you that something
is a good or bad idea by spouting technical jargon. Most of them have
no idea what they are talking about. Don't be one of those people or
their victims when it comes to stocks.
From P/E rations to EV/EBITDA, we've got your back!
Life of a company--from birth to death
This is an old set of videos, but if you put up with Sal's messy
handwriting (it has since improved) and spotty sound, there is a lot to
be learned here. In particular, this tutorial walks through starting,
financing and taking public a company (and even talks about what happens
if it has trouble paying its debts).
Dilution
When companies issue new shares, many people consider this a share
"dilution"--implying that the value of each share has been "watered
down" a bit. This tutorial walks through the mechanics and
why--assuming management isn't doing something stupid--the shares might
not be diluted at all.
Mergers and acquisitions
Companies often buy or merge with other companies using shares
(which is sometimes less intuitive than when they use cash). This
tutorial walks through the mechanics of how this happens and details
what is likely to happen in the public markets because of the
transaction (including opportunities for arbitrage).
Leveraged buy-outs
Private equity firms often borrow money (use leverage) to buy
companies. This tutorial explains how they do it and pay the debt.
Bonds
Both corporations and governments can borrow money by selling
bonds. This tutorial explains how this works and how bond prices relate
to interest rates. In general, understanding this not only helps you
with your own investing, but gives you a lens on the entire global
economy.
Corporate bankruptcy
Anybody or anything (you can decide if a corporation is a person)
can have trouble paying its debts. This tutorial walks through what
happens to a corporation in these circumstances.

Investment vehicles, insurance and retirement
Mutual funds and ETFs
If we're not in the mood to research and pick our own stocks,
mutual funds and/or ETFs might be a good option. This tutorial explains
what they are and how they are different.
Retirement accounts: IRAs and 401ks
The government apparently wants us to save for retirement (not
always obvious because it also wants us to spend as much as possible to
pump the economy going into the next election cycle). To encourage
this, it has created some ways to save that avoid or defer taxes: IRAs
and 401ks.
Life insurance
It is a bit of a downer to think about, but we are all going to
die. Do we care what happens to our loved ones (if they really are
"loved" than the answer is obvious). This tutorial walks us through the
options to insure our families against losing us. The reason why we
stuck it in the "investment vehicles" topic is because it can also be an
investment that we can use before we die.
Hedge funds
Hedge funds have absolutely nothing to do with shrubbery. Their
name comes from the fact that early hedge funds (and some current ones)
tried to "hedge" their exposure to the market (so they could, in theory,
do well in an "up" or "down" market as long as they were good at
picking the good companies). Today, hedge funds represent a huge class
investment funds.
They are far less regulated than, say, mutual funds. In exchange for
this, they aren't allowed to market or take investments from
"unsophisticated" investors. Some use their flexibility to mitigate
risk, other use it to amplify it.

Money, banking and central banks
Banking and Money
We all use money and most of us use banks. Despite this, the
actual working of the banking system is a bit of a mystery to most
(especially fractional reserve banking).
This older tutorial (bad handwriting and resolution) starts from a basic
society looking to do more than barter and incrementally builds to a
modern society with fraction reserve banking. Through this process, you
will hopefully gain a deep understanding of how money and banking works
in our modern world.

Quantative easing
You know that the Federal Reserve (or central banks in general)
controls the money supply and short-term interest rates. But how
exactly do they do this. Even more, how is "quantitative easing"
different than regular open market operations.
This tutorial explains it all in the context of the Federal Reserves
attempts to stave off deflation during the 2008-2012 recession.
2008 Bank bailout
In 2008, the entire financial system was at a potential breaking
