Brad said this?

A reader of mine provided me with this quote (apparently, from Brad DeLong):
I learned this from Andy Abel and Olivier Blanchard before my eyes first opened: increases in government purchases are ineffective only if (a) "Ricardian Equivalence holds and (b) what the government buys (and distributes to households) is exactly what households would buy for themselves. RE by itself doesn't do it." 

Macromania quoting.

I am a little confused since about half of the federal government is devoted to providing what household normally provide for themselves. Brad, for example, just indicated that food stamps have low multipliers. Who would have known? This explains the Dollars for Clunkers fail, people buy cars anyway. This also explains why stimulus would have such a low multiplier when essential goods, like energy, are in short supply.

Also, while we are on the subject, does anyone still doubt that pushing monetary stimulus causes price spreads to appear?
