Econ 001.1 : The Concept of Interest Rate

Before I talk about fancy concepts, I figured I should talk about a topic that lies at the heart of economics.

Why is there an interest rate in the first place?

If you don't understand the question, if I borrow money from you, why should I pay you more tomorrow than today? In fact, why should I pay you at all?

Ah, ha!

Lending money comes with risk. The risk that the counterparty may never pay it back at all.

So money tomorrow is worth a little more than money today, and that's why lenders charge interest!

We're going on to build on this modest concept so hang with me.
