Perhaps you should try some spelling variations:
"economic interactionism" » "economic interaction", "economic intersections", "dynamic interactionism"
"economic interactions" » "economic integration", "dynamic interactions", "economics international"

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: (("economic interactionism") OR ("economic interactions"))*.
• Removing quotes may allow a broader search: (( economic interactionism ) or ( economic interactions ))*.
