Thanks, but I'll own this one. The primary problem with the stimulus was indeed simply that it was too small. Even with the misdirected monies and the inefficiencies, a "bigger hammer" would still have had a larger effect, enough to pull the economy out of the deflationary slump that was the actual predicted effect of too small a stimulus.
YoPopa suggests that what is really needed is "some action that would make it easier for an individual to set up in business." I'd like to submit that that's exactly what he did see, but he didn't see enough of it.
What does he actually need in order to set up in business? Customers, and startup funding. Well, he's not going to get any startup funding if the banks aren't lending -- and the whole purpose of TARP was to break the credit crunch of late 2008 and get the banks lending again instead of just sitting on cash. And that bit of the stimulus largely worked, in that banks are now lending again (at all), but they're still being very cagey with their money. Putting more money into circulation -- creating moderate inflation -- would force banks to lend out more of their money because "just sitting on it" would actually lose them money. That's an argument not for a different stimulus, just for a larger one.
Similarly, customers : you can't sell things to people who don't have money to spend. People who don't have jobs and don't have income can't spend stuff. Giving people who don't have jobs a compensatory income -- whether that be through food stamps, or through unemployment benefits -- gives them money to spend, so they can afford to be YP's customers. The more money that gets put into circulation that way, the more money YP can tap into. Again, that's an argument simply for more stimulus, not for a different one.
And, of course, if more customers means more businesses created, it also means more jobs, and the unemployment problem fixes itself. The reverse is also true; the more people aren't working, the fewer customers existing firms have, and the more likely they are to have to continue cutting staff. Again, this is an argument simply for a larger stimulus....
Of course, we can tune the existing stimulus to make it more effective; raising the amount spent on food stamps and eliminating the tax cuts would have given a lot more bang for buck. (Rich people don't spend tax cuts, they bank them.... and banks aren't lending out much today. Poor people, by contrast, spend their food stamps.)
