For background and elementary review of the issues covered in this Lesson
you should consult the text entitled Economics, by
Richard G. Lipsey, Paul N. Courant and Douglas D. Purvis,
Eighth Canadian Edition, published by Harper Collins. Alternatively,
you could refer to the text Economics by Joseph E. Stiglitz
which was published by W.W. Norton in 1993. Another alternative
is the book Introduction to Positive Economics by
Richard G. Lipsey which was published by Weidenfeld & Nicholson
in London in 1963. Though this book is old, the important material
is equivalent to that in the newer editions of Lipsey's joint work.
