Style Guidelines for Accepted Papers

Mathematical Style

  1. Displayed equations should be numbered, with the number appearing at the right hand edge of the line.
  2. Use least cost mathematical notation to the extent possible.
  3. There is a major difference between mathematics that is embedded in ordinary lines of text and mathematical expressions that are "displayed" (i.e. set out in separate numbered lines). In particular, for fractions contained in lines of ordinary text, please print them in "horizontal" form, using a slash and parentheses. The "vertical" form, with the numerator literally above the denominator, is much more difficult to incorporate. If you need to use the vertical form, do so by having the expression displayed in a separate numbered line. Also, it is much better to have a vertical fraction displayed in a separate line rather than a complicated horizontal fraction embedded in a line of text.
  4. The principle outlined in the previous point applies generally, not just to fractions: complicated mathematical expressions should be displayed in separate numbered lines rather than embedded in lines of text.
  5. Avoid subscripts on subscripts, and superscripts on superscripts.
  6. When copy-editing equations, we use small capitals to represent variables made up of two letters (like MC for "marginal cost") so they are distinguished from the product of M and C, which would appear as capitalized italics.
