Discipline: Economics
Developed by Scottish economist Adam Smith (1723-1790), real bills doctrine asserts that there can never be an inflationary excess issue of commercial bills and other paper money because each bill represents a real transaction.
Real bills doctrine was later criticized for failing to recognize that the same sum of money can support many bills.
