Compensation: The gruesome details

This series of pages is designed to give a much more complete overview of compensation than the informal discussion. It contains examples as well as mathematical treatments necessary to understand compensation thoroughly. It also covers the pitfalls of compensation, and details some of the more esoteric points that are involved in the process. To reference any of this material, see the introduction to the informal discussion.

Currently, there is no way to download the complete set of these pages at once, for printing.

These pages are designed to be navigated in order; however, you can jump directly to some of the sections (marked with an *) without losing too much from previous pages.
