A nice way to integrate the Keynesian cross analysis with the AD/AS analysis is to do the
former in nominal terms. This allows a straight carryover to the AD/AS space with the
shape of the AS curve giving the breakout of the P/Q
change for any nominal income change arising from a shift of AD, the latter determined by
the Keynesian cross analysis.
 
It is my understanding that there were a few textbooks that did this, Dolan for one, some
time ago. But it seems to have become unacceptable.
