Whether or not to enforce a no-fly zone over Libya is becoming a hot issue in Washington. Many lawmakers like Senator John McCain (R-Ariz.) and Senator John Kerry (D-Mass.), are calling for a no-fly zone, as rebels in Libya face rough times against the better equiped Libyan armed forces.

If you had told me, 13 years ago, that Apple would one day be deemed more valuable than Microsoft, I would have laughed and laughed and laughed. I wanted it to happen, mind you, but knew it would only come about in some science fiction world where the better product was actually rewarded by consumers and the markets worked as perfect dowsing rods for business acumen. I would have chuckled ruefully, and gone home through a Microsoft-dominated world to talk to my aging Mac Powerbook 520.

Today, at 4 p.m., the unthinkable happened: Apple Inc. finished the day worth more (in the eyes of those buying its stock) than its once-chief rival, Microsoft Corporation. As the markets closed, Apple's stock price put the company at $222 billion, just over Microsoft's $219 billion.

Stock markets around the world seemed jittery yesterday: The Dow Jones industrials dropped briefly below 10,000 before making up most of their loss.

The sub-prime mortgage crash of two years ago was not about mortgages and it was not about complexity of derivatives and the cross-betting lunacy of credit default swap insurance voodoo. It was about the simplest thing in economics: price. If you can’t find a price, there is no sale, no market, no value, no money. In that instance, everything seizes up and you see what happened yesterday, for a while, on Wall Street.

Investment banks are reporting generally positive earnings, lawsuits stemming from the financial crisis are hitting the courts, and the stock market passed the 10,000 mark for the first time in a year. It's been quite a week in the economy; Lakshman Achuthan, from the Economic Cycle Research Institute, stops by the Takeaway to explain it.

Yesterday the Dow Jones Industrial Average closed above the symbolic threshold of 10,000. New York Times finance reporter Louise Story says the news is interesting, but it doesn't say much about the overall health of the economy. Something that might: the banking sector. Also joining the conversation is New York Times economics correponsdent Edmund Andrews with a look at how the U.S. Treasury wants some bailed-out banks to start paying back their loans.
