Bitcoin: Bubble or Piratization of Central Bank Money?

In 2009 Satoshi Nakamoto invented a new electronic or virtual currency called Bitcoin, the design goal of which is to provide an equivalent of cash on the Internet. Rather than using banks or credit cards to buy stuff online, a Bitcoin user will install a piece of software, the Bitcoin client, on her computer and send Bitcoin directly to other users under a pseudonym. One simply enters into the software the pseudonym of the person one wishes to send Bitcoin and the amount to send and the transaction will be transmitted through a peer-to-peer network. What specifically one can get with Bitcoin is somewhat limited to the few hundred websites which accept them, but includes other currencies, web hosting, server hosting, web design, DVDs, coffee in some coffee shops, and classified adverts, as well as the ability to use online gambling sites despite being a US citizen and to donate to Wikileaks.

The pension reforms of the years 2000 until 2007 were supposed to attenuate the foreseeable effects of demographic change on the pension system. This is why the retirement age was raised, the pension level was lowered and a so-called sustainability factor (“Nachhaltigkeitsfaktor”) was introduced into the pension formula. This approach meant a fundamental change of objectives – from safeguarding living standards in retirement to the stability of contribution rates. The lower future pension level is to be complemented by the subsidised formation of a private capital stock (“Riester pension”) without employer participation. The analysis of the macroeconomic consequences of this reform shows that the chosen policy of enhanced funding both dampens growth and leads to insufficient income in old age. Thus the current strategy is not suitable for alleviating the demographic burden.
