Economist following poet in town (6)

I believe the answer is:

keynes

'economist' is the definition.
(I know that Keynes is a economist)

I cannot understand how the remainder of the clue works.

(Other definitions for keynes that I've seen before include "SECOND PART OF 15" , "See 14 Across" , "20th century economist" , "English economist, d. 1946" , "John Maynard --, English economist" .)
