This week saw the end of a years-long, international, multi-billion-dollar battle over one of the most boring things in finance: savings accounts.

At the center of the battle was Iceland, a tiny country where the banks grew into international behemoths during the credit bubble.

The banks got so big partly by convincing foreigners to open up online savings accounts. In particular, lots of people in England and Netherlands opened up "ICESAVE accounts" with a bank called Landsbanki. During the financial crisis, the bank collapsed.

A plain, one-bedroom apartment in Williston, N.D., rents for $2,100 a month. For this price, you could rent a one-bedroom apartment in New York City.

Williston is not New York City. There are 30,000 residents and one department store. The nearest city is two hours away.

Rents are so high in Williston because the town is in the middle of an oil boom. Unemployment is below 1 percent, and workers are flooding into town.

The tortuous negotiations involved in the "fiscal cliff" talks are like a chess game.

To shed some light on the kinds of negotiation techniques that members of Congress might be using during the talks, we asked two negotiators to walk us through their tactics with examples from their everyday lives.

Shawn Rux took over as principal of MS 53, a New York City middle school, last year. At the time, 50 or 60 kids were absent every day. You could understand why they stayed away: The school was chaos.

Twenty-two teachers had quit, the entire office staff had quit, and hundreds of kids had been suspended. The school was given a grade of F from the city's department of education.

"It was in a bad place," Rux says.

Here's a quick rundown on three of the most impenetrable terms related to the fiscal cliff. For more, see our post, The Fiscal Cliff In Three And A Half Graphics.
