Given the previous discussion, I assume that Robert Leeson means to 
include me among "AD True Believers."  Let me point out that such a 
conclusion would outrun the evidence.  The point of my intervention was 
to try to provide some clarity, which I found completely lacking in the 
discussion, about where the AD comes from and how it relates to other 
relationships in standard textbook models.  But far from being a true 
believer,  neither the AD curve nor the LM curve are elements of the 
core of my textbook in progress.
