Small business optimism spikes: Small business owners are feeling better than they’ve felt in more than three years, according to a new Wells Fargo/Gallup Small Business Index released Tuesday. The report shows an increase from the final quarter of 2011 in owners’ perceptions about revenues, financing, hiring, credit access and cash flow.

Silicon Valley recovering faster than rest of the country: The California region added a total of 42,000 jobs last year, bringing the area’s workforce back to its 2006 and 2007 levels of 1.2 million people, according to a new report on Silicon Valley released Tuesday. The job growth was significantly faster than the 1.1 percent increase nationwide.

However, that’s partly because the fund has helped far fewer banks than Congress had originally intended.

Low-skill workers left behind in recent unemployment drops: By disproportionate numbers, low-skill American laborers have given up looking for work, making the nation’s recovery appear better than it is. If the unemployment rate counted the 2.8 million people who want jobs but have stopped looking, it would sit at 9.9 percent rather than its current 8.3 percent.
