Perhaps you should try some spelling variations:
reducing inequality » reducing inequalities, measuring inequality, education inequality
garding inequality » garding's inequality, hardy inequality, rising inequality
hardy's inequality » hardy inequality, holder's inequality, harnack inequality
wage » wave
earnings » learning, warning

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wage AND ((reducing inequality) OR (((((garding inequality) OR (hardy's inequality))) OR (earnings inequality))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wage and ((reducing inequality) or (((((garding inequality) OR (hardy's inequality))) or (earnings inequality))))*".
