Perhaps you should try some spelling variations:
"advances in advanced microeconomics" » "advances in advanced macroeconomics", "advances in advanced microelectronics", "advances in advanced exergoeconomic"
"advances in approach microeconomics" » "advances in approach macroeconomics"
"advances in approach microscopic" » "advances in approach macroscopic", "advances in approach laparoscopic", "advances in approach arthroscopic"

Try widening your search to All Fields.

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: (("advances in advanced microeconomics") OR ((("advances in approach microeconomics") OR ("advances in approach microscopic")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advances in advanced microeconomics\") or (((\"advances in approach microeconomics\") OR (\"advances in approach microscopic\"))))".
• Removing quotes may allow a broader search: (( advances in advanced microeconomics ) or ((( advances in approach microeconomics ) OR ( advances in approach microscopic )))).
• Adding a wildcard symbol may retrieve word variants: (("advances in advanced microeconomics") or ((("advances in approach microeconomics") OR ("advances in approach microscopic"))))*.
