Global stock markets, overreacting to Dubai's debt woes, could mark down stocks too much. Dubai -- which is famous for building a palm-shaped island, the world's tallest building, an indoor ski slope, and paying Rihanna $500,000 to perform at a New Year's Eve party -- wants a six-month reprieve from repaying a $3.5 billion bond.

Why would this be an overreaction? The cost of writing-off Dubai's debt is a tiny fraction of the write-offs from the financial crisis that took $30 trillion off world stock markets in 2008.

Reuters reports that even if Dubai defaults on every penny of its $80 billion in debt, the write-offs that banks will take would be 2.86% of the total write-offs -- $2.8 trillion -- banks will take in the wake of the financial crisis between 2007 and 2010, according to the International Monetary Fund. But the risk to banks outside the Middle East is likely to be far less than $80 billion. According to Reuters, their liabilities related to Dubai World could be as high as $12 billion in so-called syndicated and bilateral loans. To be fair, big banks in the Middle East are exposed -- Abu Dhabi Commercial Bank by $2.45 billion and First Gulf Bank by $1.36 billion.

As corporate budgets shrink, so do business trips. Looking to avoid paying for overnight hotel stays, cost-conscious companies are increasingly asking employees to squeeze all their away meetings into one day -- and then turn around and fly home.

Headhunter Marc Lewis, who frequently flies between coasts on his clients' tab to interview job candidates, says the single-day business trip is becoming a familiar drill. "Several clients have suggested to us that if we're ok with it, they would prefer for us to take the red-eye home rather than stay overnight," says Lewis, founder and CEO of Leadership Capital Group, an executive search firm based in Westport, Conn.

Earlier this month, it was reported that Bank of America (BAC) might not announce a replacement for departing CEO Ken Lewis until Thanksgiving.

Now Thanksgiving has come and gone, and there is still no word of a new CEO for Bank of America.

"The selection process is continuing, internal and external candidates are being considered and a decision will be made in the near future," BofA spokesman Scott Silvestri told CNBC, which is speculating that the process could linger on into next year.
