...sounds good because it's for small businesses and job creation," says economist Dean Baker of the liberal-leaning Center for Economic and Policy Research. "But basically, you are paying companies to hire workers that would have been hired even if you hadn't handed out tax breaks...
Just how many companies would get the tax credit undeservedly is up for debate. If the Cash for Clunkers program or the homebuyers' tax credit is any guide, the number would be relatively high. Car-research firm Edmunds estimates that just 18% of the nearly 700,000 automobiles that were bought through the Cash for Clunkers program were a result of the stimulus. The rest, 82%, went to people who would have gotten new wheels anyway. The $8,000 homebuyer tax credit did a little better. In that instance, economists estimate that 33% of the 1.4 million people who collected...
...hard to remember even things we don't want to forget? The problem, suggests a growing body of research, may be that we're thinking about them too much in the first place...
While the NYU study tested memory and simple recognition, other recent research looking at activity in the brain at rest and the learning of complex visual tasks has yielded similar results. Neurologist Maurizio Corbetta of Washington University in St. Louis recruited 14 people to use their peripheral vision to identify a hidden pattern - an inverted T - that was flashed briefly on a screen inside an fMRI machine. After each daily training session, lasting one to two hours for about a week, participants were given an hour's rest, during which time Corbetta scanned their brains. (Read "The fMRI Brain Scan...
...regions of the cerebral cortex appeared to be correlated after the participants had learned the visual task, but were not linked beforehand. The brain activity in those who were best at finding the hidden pattern onscreen was most strongly related. "Our test was like a video game. What this research shows is that we have a very dynamic landscape of ongoing activity [in the brain] even when we are at rest," notes Corbetta...
