Perhaps you should try some spelling variations:
employment development » employee development, development development, environment development
regional economic » regional economics
global economic » global economy
legal economic » local economic, special economic, general 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)) AND employment 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)) and employment development (leed) working papers".
• Adding a wildcard symbol may retrieve word variants: oecd ((((legal economic) OR (global economic))) or (regional economic)) and employment development (leed) working papers*.
