Courtesy of INET, here is Pavlina Tcherneva explaining her “bottom up” approach to fiscal policy.

Notice the way she uses the term “trickle down” to apply also to conventional pump-priming fiscal policy (targeting growth and hoping for the right employment side-effects).  We need to move beyond the conventional options on fiscal policy, says Tcherneva; beyond a fiscal policy space marked out by aggregate demand management on one end and austerity on the other.  There’s a third approach that’s more in tune with the “original Keynesian spirit,” as she puts it:  directly employing the unemployed.  We should be targeting employment and the unemployed directly rather than trying to achieve this through the kind of bank-shot maneuver represented by conventional pump priming.
