Economy's tumble even worse than expected in 3Q

The economy took a tumble in the summer that was worse than first thought as American consumers throttled back their spending by the most in 28 years, further proof the country is almost certainly in the throes of a painful recession.

The updated reading on the economy's performance, released Tuesday by the Commerce Department, showed the gross domestic product shrank at a 0.5 percent annual rate in the July-September quarter.

That was weaker than the 0.3 percent rate of decline first estimated a month ago, and marked the worst showing since the economy contracted at a 1.4 percent pace in the third quarter of 2001, when the nation was suffering through its last recession.
