A guide to hyphenation in economics? In the econ literature, what is the convention when it comes to (not) hypenating some common terms like:


first(-?)best, second(-?)best,...
best(-?)response?
...


The Economist suggests that "There is no firm rule to help you decide which words are run together, hyphenated or left separate" so I thought people here could be more aware of the conventions in econ than people, say, at http://english.stackexchange.com.
Plamen Nikolov of Binghamton University presents a brief treatment of this in "Writing Tips For Economics Research Papers". He notes that there are two basic rules of economic usage: 


  "Long run" (without a hyphen) is a noun. "Long-run" (with a hyphen) is
  an adjective. Same with short(-)run. and "Saving" (without a terminal
  s) is a flow. "Savings" (with a terminal s) is a stock.
