to the real bills doctrine. After the mid 19th century, though, economists interested in monetary issues focused their attention elsewhere, and free banking received little attention. Free banking as a subject of renewed debate among economists got its modern start in 1976 with The Denationalization of Money, by economist Friedrich Hayek, who advocated that national governments stop claiming a monopoly on the issuing of currency, and allow private issuers like banks to voluntarily compete to do so. In the 1980s, this expanded into an increasingly elaborate theory of free market money and banking, with proponents Lawrence White, George Selgin, and Richard Timberlake increasingly centering their writing and research around the concept, either regarding modern theory and application, or researching the history of spontaneously free banking. Australia In the late 19th century, banking in Australia was subject to little regulation. There were four large banks with over 100 branches each, that together had about half of the banking business, and branch banking and deposit banking were much more advanced than other more regulated countries such as the UK and US. Banks accepted each other's notes at par. Interest margins were about 4% p.a. In the 1890s a land price crash caused the failure of many smaller banks and building societies. Bankruptcy legislation put in place at the time gave bank debtors generous terms they could restructure under, and most of the banks used this as a means to restructure their debts in their favor, even though they did not really need to. Switzerland In the 19th century, several Swiss cantons deregulated banking, allowing free entry and issue of notes. Cantons retained jurisdiction over banking until the enactment of the Federal Banking Law of 1881. The centralisation of note issue reduced the problem of the existence of "a bewildering variety of notes of varying qualities ... at fluctuating exchange rates." Scotland Scottish free banking lasted between 1716 and 1845, and is arguably the most researched and developed instance of free banking. The system was organized around three chartered banks – the Bank of Scotland, the Royal Bank of Scotland, and the British Linen Company – and numerous unchartered banks. It resulted in a highly stable and competitive banking system. United States Although the period from 1837 to 1864 in the US is often referred to as the Free Banking Era, the term is a misnomer in terms of the definition of "free
