Is the law of reflux valid?

In the classical monetary debates, the Banking School held that notes would be equally demand-elastic whether supplied by many or a single issuer. The Free Banking School held that notes would be less demand-elastic if supplied by a single issuer. These assertions have rarely, if ever, been subject to more stringent statistical testing. In this paper I compare the elastic properties of the note stock of the Swedish note banking system in 1880-1895 with those of the regime in 1904-1913, when the Bank of Sweden held a note monopoly. Evidence suggests that notes did not become less elastic after monopolisation, thus lending support to the views of the Banking School. -- Banking School ; Free Banking School ; Elastic currency ; Clearing mechanism ; Needs of trade ; Law of Reflux ; Real bills doctrine
