Some of my recent health care stories from Businessweek:

Health Reform’s Small Business Confusion: Many companies still don’t know how the law will affect them.

Getting a Grip on Medicine’s Slippery Price Tag: How the cost of basic tests can vary widely depending on what doctor you see.

Small Business Makes a Risky Bet on Health Care: Why more small companies are dropping traditional insurance to go it alone, and how that could threaten the effectiveness of health reform.

Yelp went public this week. Yesterday we looked at it’s local advertising business, which accounts for 70 percent of its revenue.

Recently in Bloomberg Businessweek:

A graphic showing who on Wall Street is still raising money for Obama.

A chart that shows the shrinking role of small business in the economy. (For more, see this earlier blog post.)

I spent some time working behind the scenes to help put together this package on top-performing companies in the S&P 500 that’s in this week’s Bloomberg Businessweek. The great work of our designers, who had a four-page spread to play with, isn’t fully reflected online, so you should go buy the magazine to get the full experience.

Also: Today on Businessweek.com, a look back at Obama’s year-old effort to cut red tape, and why it isn’t as simple as he makes it sound.

Today on Businessweek.com, a look inside the business of mail order food, an American holiday tradition.

My latest piece in Bloomberg Businessweek looks at housing’s twin blows to small business.
