There are a number of successful examples of the introduction of money with a hoarding tax. Wörgl is the best known example. During the Great Depression, the Austrian town of Wörgl made economic history by introducing a complimentary currency. The mayor Michael Unterguggenberger had a long list of projects he wanted to accomplish, but there was hardly any money with which to carry them out. Rather than spending the 40,000 Austrian schillings in the town’s coffers to start these projects off, he deposited them in a local savings bank as a guarantee to back the issue of a type of complimentary currency known as 'stamp scrip'. The Wörgl currency required a monthly stamp to be stuck on all the circulating notes for them to remain valid, amounting 1% of the each note’s value.
Because nobody wanted to pay what was effectively a hoarding fee, everyone receiving the notes would spend them as fast as possible. The 40,000 schilling deposit allowed anyone to exchange scrip for 98 per cent of its value in schillings. This offer was rarely taken up though. Over the 13-month period the project ran, the council not only carried out all the intended works projects, but also built new houses, a reservoir, a ski jump, and a bridge.
The key to its success was the fast circulation of scrip within the local economy, 14 times higher than the Schilling. This in turn increased trade, creating extra employment. At the time of the project, Wörgl was the only Austrian town to achieve full employment. Six neighbouring villages copied the system successfully. In January 1933, the project was replicated in the neighbouring city of Kirchbuhl, and in June 1933, two hundred Austrian townships were interested in adopting the idea. At this point the central bank panicked and decided to assert its monopoly rights by banning complimentary currencies. The people unsuccessfully sued the bank and later lost in the Austrian Supreme Court. It then became a criminal offence to issue 'emergency currency'.
