Perhaps you should try some spelling variations:
"studies in macroeconomic factors" » "studies in macroeconomic indicators", "studies in macroeconomic effects", "studies in macroeconomic data", "studies in macroeconomic sectors", "studies in macroeconomic history"
"studies in socioeconomic factors" » "studies in socioeconomic status", "studies in socioeconomic sectors", "studies in socioeconomic history"
"studies in macroeconomic theory" » "studies in macroeconomic reform", "studies in macroeconomic trends", "studies in macroeconomic reforms"
"studies in economic factors" » "studies in economic sectors", "studies in economic history"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("studies in macroeconomic theory") or ((((((("studies in macroeconomic factors") OR ("studies in economic factors"))) or ("studies in socioeconomic factors"))) or ("studies in macroeconomic framework"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("studies in macroeconomic theory") OR ((((((("studies in macroeconomic factors") OR ("studies in economic factors"))) OR ("studies in socioeconomic factors"))) OR ("studies in macroeconomic framework")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"studies in macroeconomic theory\") or (((((((\"studies in macroeconomic factors\") OR (\"studies in economic factors\"))) or (\"studies in socioeconomic factors\"))) or (\"studies in macroeconomic framework\"))))".
• Removing quotes may allow a broader search: (( studies in macroeconomic theory ) or ((((((( studies in macroeconomic factors ) OR ( studies in economic factors ))) or ( studies in socioeconomic factors ))) or ( studies in macroeconomic framework )))).
• Adding a wildcard symbol may retrieve word variants: (("studies in macroeconomic theory") or ((((((("studies in macroeconomic factors") OR ("studies in economic factors"))) or ("studies in socioeconomic factors"))) or ("studies in macroeconomic framework"))))*.
