Perhaps you should try some spelling variations:
environment development » development development
employment development » employee development, development development, employment unemployment
regional economic » regional economics
global economic » global economy
legal economic » special economic, general 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 ((((legal economic) OR (((global economic) OR (regional economic))))) OR (local economic)) AND ((employment development) OR (environment development)) (leed) working papers.
• The words AND, OR and NOT may confuse the search; try adding quotes: "oecd ((((legal economic) or (((global economic) OR (regional economic))))) or (local economic)) and ((employment development) or (environment development)) (leed) working papers".
• Adding a wildcard symbol may retrieve word variants: oecd ((((legal economic) or (((global economic) OR (regional economic))))) or (local economic)) and ((employment development) or (environment development)) (leed) working papers*.
