Talk:Transfer problem

What is this?
Paul Krugman has a recent column with "Transfer problem" in the title, but I can't figure out what the definition is well enough to improve this article. power~enwiki ( π, ν ) 19:17, 18 October 2017 (UTC)

Context
For this article, I did copyedit the lead section to clarify the context, and added a "See also" section, then removed the Context notice. While I have a general familiarity with the subject, but not expert, so if these updates are not agreeable, please alter to improve. JoeNMLC (talk) 20:35, 10 October 2021 (UTC)
