Finance uses lots of arithmetic, because questions are often about dollars and cents.
Algebraic formulas are just translated arithmetic.
Mathematical sophistication does not help. There is no higher math in this course: 99.9% of what we do is 10th-grade high school level. The remaining 0.1% is a few logarithms, and perhaps one or two derivatives. (There are no integrals, no linear algebra, vectors, and matrices, much less real algebra.)
Mathematical aptitude does help, and tremendously so. The reason is that it makes working with numbers and formulas easier. If you have little mathematical aptitude, you have to work three times as hard. With good attitude and work, everyone can do well. Without it, you will fail.
This is not a vocational course. Still, if you want to get a job in investment banking, in consulting, or in a corporate finance department, you have to know the stuff in Economics 1720 “cold.”
It is more important to know the basics well and be able to apply it to new situations, than it is to know everything there is to know.
Institutional details are often better taught on-the-job.
The goal of Economics 1720 is ambitious: it is not only for you to learn corporate finance, but also for you to learn how to approach financial and economic problems.
I am here to help you learn applying the basic concepts well .
Capstone: Pro Forma
At the end of the course, you will be asked to integrate all your knowledge. I will force this by asking you to produce a so-called pro forma analysis of a business or business opportunity.
Creating a pro forma requires understanding everything: capital budgeting, financial statements, the cost of capital, financing and capital structure, governance, etc.
Such pro formas are the bread and butter of all business presentations.
Finance also requires that you acquire the “finance mode of thinking” and the “finance jargon.” It is the standard for conversation in the world out there. And, of course, you still need to learn finance first before my statement here makes sense to you.
IMPORTANT:
You must learn how to reason in financial terms.
You muse also learn the language of finance (Jargon).
Please stop me if I use jargon that you do not know. Financial jargon is natural to me, so I often do not realize when I speak jargon. Financial jargon can be viewed as a method of a generally accepted method of conversing about business projects.
The nature of our questions means finance requires a great deal of quantitative computation. It is not just “is this project good?,” but “what is the value of this project” aka “how good is this project”?
This course will give you a hammer, which you can then use smartly or stupidly. — In real life, a little knowledge can be a dangerous thing. 1
— You need one important filter for everything you do:
IMPORTANT: Understand what you are doing on an intuitive common-sense level! Nothing, including finance or strict rules, ever replaces common sense.

We will first solve numerical examples, and then translate them into formulas.
We will think in terms of the simplest possible examples first, and then gradually complicate up.
I want you to learn how to use this method of thinking for solving all sorts of new problems–and not just for approaching new subjects in finance.
Any complex method must also work in a simple setting, where it easiest to understand. Otherwise, the complex method is flawed.
More formally, you can call this “the bullshit test.” Or the “Emperor’s New Clothes” test.
Often, but not always, the subsequent generalization of simple examples is straightforward.
The opposite is not necessarily the case. (A simple method may be inapplicable in a more complex environment. Simplification of complex methods can be tougher than you think.)
It is no secret how you can be sure to do well in this course:
Always bring a $5 Calculator to class.
Always bring the printed class lecture notes—for the current and the next class sessions (I may proceed on).
Always read the relevant book chapter before class. (Having at least a basic roadmap makes it much simpler to follow what is happening during class.)
Always look over the relevant class lecture notes before class.
Never use your computer during class. Verboten.
Always read the relevant book chapter after class. This time it should make a lot of sense.
Always reread the filled-out lecture notes after class to make sure you are with the program.
Do the homework. Hand them in. See how you are doing on them. Learn from your mistakes.
Don’t fall behind. If you do, go see the TA as soon as possible. Don’t wait until the midterm comes around. If you do, this class will eat you up.
Read other financial newspapers and magazines. (You might also want to subscribe to the WSJ.) Have an idea of what is going on in the world. It helps you navigate this course, too.
If you do this religiously, you really cannot fail this course.
