Module Teaching Notes
At the time of this writing, the economy has been sputtering along for a couple of years. When you are
teaching this module, you may need to soften (harden) some of the descriptions in the book to reflect
whether things are better or worse than they are here in January, 2011. Hopefully, they will be better where
you are and you can talk about emerging from the mess that this module (and most of this new unit)
describes.
Anything as big as a global economic collapse has lost of causes. Although commentators on the left and
right will isolate individual specific causes, lots of factors were at work.
This module looks at several things that played a part in crashing the economy. The basic progression, as I
see it, is:
1. The government encouraged banks to make mortgage loans to people with borderline credit scores.
2. Banks ran with the idea and made loans to people with genuinely bad credit scores, who were quite
unlikely to pay the money back.
3. But banks didn’t mind, because they would unload newly-made loans soon after they were made.
4. Investment houses bundled bad loans into mortgage backed securities and other even more exotic types
of investments.
5. People bought much more house than they could afford – many of them knowing full well that they were
biting off more than they could chew.
6. Investors bought MBS and the like, ignoring the “if it’s too good to be true…” pillar of common sense
investing.
7. When large numbers of people started to default, everything fell apart.
The scenario in this module is designed to help students see the big picture, and also make a first effort at
laying relative blame. What causes are most at fault? Who bears some but not much responsibility?
