results in the need for choices by participants.
2 Participants, buyers
and sellers, exhibit purposeful behavior to enhance their own rational
self interest.
3. Marginal
analysis where the change in benefit received is balanced with the change in cost is a
common
purposeful behavior.
4. Fallacy
of composition applying to the whole that which is true for a part
without adequate proof. 1 and
3
are odd numbers, so four is odd number.
