Today’s edition of quick hits:

* The central banks act: “The Federal Reserve said Wednesday that it joined some of the world’s major central banks in a coordinated action to inject liquidity into the global financial system as the euro zone’s financial crisis threatens to squeeze credit worldwide. Joining in the move were: the Fed, The Bank of Canada, the Bank of England, the Bank of Japan and the European Central Bank, the Fed said.”

* Investors were pleased: “Stocks rallied in the United States on Wednesday after the Federal Reserve and other central banks took action to try to contain the debt crisis in the euro zone, with market indexes gaining more than 4 percent and the Dow Jones industrial average ending up 490 points.”

* Mark Thoma, Sarah Kliff, and Matt Yglesias have helpful takes on what, exactly, the central banks did today.

* Secretary of State Hillary Rodham Clinton has arrived in Nay Pyi Daw, measuring “the depth of the political and economic opening the country’s new government has unexpectedly begun.” Among the issues to consider: is it Burma or Myanmar?

* Further isolating Tehran: “Iran is rapidly heading for increased isolation from Western countries, as the European Union is set to decide during a crucial meeting Thursday in Brussels to downgrade relations, diplomats said Wednesday.”

* Shifts continue on Capitol Hill over extending the payroll tax break. Sen. Susan Collins (R-Maine) is even open to some tax increases.

* NLRB: “The National Labor Relations Board voted Wednesday to move forward with portions of a controversial union election rule after the board’s lone Republican member showed up to register his opposition.”

* Detainee policy: “Defying the Obama administration’s threat of a veto, the Senate on Tuesday voted to increase the role of the military in imprisoning suspected members of Al Qaeda and its allies — including people arrested inside the United States. By a vote of 61 to 37, the Senate turned back an effort to strip a major military bill of a set of disputed provisions affecting the handling of terrorism cases.”

* Mitt Romney’s Fox News interview yesterday really didn’t go well.

* New Hampshire Republicans tried to force through an anti-union “right to work” bill, but came up short. Good.

* NYC Mayor Michael Bloomberg probably shouldn’t think of the NYPD as his “own army.”

* Daniel Luzer on higher-ed cost cutting: “In light of Education Secretary Arne Duncan’s challenge yesterday to American universities: cut costs, somehow, it’s time to consider options.”

* Today’s quote of the day, by way of Newt Gingrich: “One of the real changes that comes when you start running for president — as opposed to being an analyst on Fox — is I have to actually know what I’m talking about.” It tells us a little something important about Gingrich’s former Fox News colleagues.
