Extensive use of what looks like fairly sophisticated mathamatical
notation is used in some economics papers I'm re-reading that describe how
various externalities and other factors are calulated related to
interdependent risk and investment behaviors.  I used to be relatively
proficient in working my way through this kind of notation - but its
been awhile and I could use some help.  Unfortunately this text editor
doesn't seem capable of accepting pasted excerpts from the papers that
include the formulas which I suspect Math type 5.0 objects.  I could
email the excerpts ...
