By MARTIN CRUTSINGERWASHINGTON (AP) â¿¿ The Federal Reserve is wrapping up 2012 the way it began the year, searching for ways to help a U.S. economy that is still struggling with high unemployment and sub-par growth. The expectation is that the Fed will announce a revamped bond-buying plan at the conclusion of their second day of discussions on Wednesday. The Fed's policy statement will be followed by the release of a revised economic outlook and a news conference with Federal Reserve Chairman Ben Bernanke. If the central bank does revamp its bond purchases, the goal would be to keep downward pressure on long-term interest rates and encouraged individuals and businesses to borrow and spend more. The Fed's final meeting of the year is being held against the backdrop of the looming "fiscal cliff," the sharp tax increases and spending cuts that will hit the economy in January if Congress and President Barack Obama are unable to reach an agreement this month to avert them. Bernanke has said that the Fed's efforts will not be able to rescue the economy if the budget negotiations fail and the country does go over the fiscal cliff. Fears of the cliff have led some U.S. companies to delay expanding, investing and hiring. Manufacturing has slumped. Consumers have cut back on spending. Unemployment remains a still-high 7.7 percent. If higher taxes and government spending cuts were to last for much of 2013, most experts say the economy would sink into another recession. The expectation is that the Fed will unveil a program Wednesday to buy $45 billion a month in long-term Treasurys. That would replace an expiring program called Operation Twist. With Twist, the Fed sold $45 billion a month in short-term Treasurys and used the proceeds to buy the same amount in longer-term Treasurys.
