Perhaps you should try some spelling variations:
"oeconomique politique" » "economiques politiques", "economie politique", "d'economie politique"
"economics politique" » "economico politique", "economico politiques", "economie politique"
"economic politique" » "economico politique", "economie politique", "economico politiques"

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: (((("economics politique") OR ("economic politique"))) OR ("oeconomique politique")).
• Removing quotes may allow a broader search: (((( economics politique ) or ( economic politique ))) or ( oeconomique politique )).
• Adding a wildcard symbol may retrieve word variants: (((("economics politique") or ("economic politique"))) or ("oeconomique politique"))*.
