The Fairway supermarket in Red Hook, Brooklyn is the sort of place New Yorkers, accustomed to cramped spaces, talk about with amazement. It's an actual, full-size supermarket, right at the edge of New York Harbor.

It's a beautiful setting, but one that was diastrous last week, when Sandy came through.

"There were five feet of water throughout the store," Bill Sanford, the president of the company told me. "Everything was submerged."

They had to throw out dumpsters worth of food. Chicken, fish, vegetables.

Just about every president since Richard Nixon has set energy independence as a goal, and both major candidates have brought it up the current campaign.

As it turns out, there is a place, not so far from here, that has achieved energy independence: Canada.

Canada produces far more oil than it consumes. They're not dependent on the Middle East! They've got all the oil they need!

I called Stephen Gordon, a professor of economics at Université Laval in Quebec City, to ask him about what energy independence means for his nation.

The story of the birth of accounting begins with numbers. In the 1400s, much of Europe was still using Roman numerals, and finding it really hard to easily add or subtract. (Try adding MCVI to XCIV.)

But fortunately, Arabic numerals (1, 2, 3, 4, etc.) started catching on, and with those numbers, merchants in Venice developed a revolutionary system we now call "double-entry" bookkeeping. This is how it works:

He Won't Tell You His Name, But He'll Help You Hide Your Money

Meet Adam Wolf*, your asset protection adviser. (*Not his real name.)

We set up our shell companies. Then we wondered: What do people actually do with shell companies?

One popular use, it turns out, is what professionals call "asset protection." Ordinary people call this "hiding money."

Maybe you're a surgeon worried a patient might sue you and take everything you have. Or you want to hide money from your ex (or your soon-to-be ex).

Insurance Companies Send Out Rebate Checks; Economists Get Nervous

Originally published on Thu September 20, 2012 3:41 pm

Nearly 13 million Americans have gotten, or will soon be getting, rebates from their health insurance companies. This is because of a provision in the Affordable Care Act (aka Obamacare) that's supposed to force insurance companies to run better.

But while the idea of getting a check from your health insurance company may sound great, some economists worry this rule could actually make health insurance more expensive.
