Volokh Corrections #28 and #29: Adler should study environmental groups, Lindgren should review abstracts more carefully
Analysis of unemployment data suggests that extended unemployment insurance benefits have not been important factors in the increase in the duration of unemployment or in the elevated unemployment rate.
First, the extension of UI benefits, which represents an increase in their value, may reduce the intensity with which UI-eligible unemployed individuals search for work. This could occur because the additional UI benefits reduce the net gains from finding a job and also serve as an income cushion that helps households maintain acceptable consumption levels in the face of unemployment shocks (Chetty 2008). Alternatively, the measured unemployment rate may be artificially inflated because some individuals who are not actively searching for work or who are unwilling to take available jobs are identifying themselves as active searchers in order to receive UI benefits.

This part of the OP interested me, re that either P or As had to be added for the bacteria to grow:
"(21) Agreed, with the proviso that the media be tested and shown to be identical except for the phosphate and arsenate. But this wouldn't mean that arsenic replaced phosphorus in any biological molecules in GFAJ cells, just that the cells needed arsenate for something."
That cells needed arsenate for something would be an interesting finding, I'd guess. And cells need As for something that P does is also implied by this finding.
Is this an area of potential agreement between the original article authors and critics?
(IANAS, BTW, so YMMV)
