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

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