Perhaps you should try some spelling variations:
development development » development developing, development environment
employment development » employee development, employment unemployment, component development
global economic » global economy, regional economic
local economic » social economic, special economic
working papers » working paper

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: oecd ((local economic) OR (global economic)) AND ((((employment development) OR (environment development))) OR (development development)) (leed) working papers*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "oecd ((local economic) OR (global economic)) and ((((employment development) or (environment development))) or (development development)) (leed) working papers*".
