grad gesehen beim Befolgen meines eigenen Ratschlags:
"liquidity trap" hat sogar einen wikipedia Eintrag

http://en.wikipedia.org/wiki/Liquidity_trap

quote:
A liquidity trap is a situation described in Keynesian economics in which injections of cash into an economy by a central bank fail to lower interest rates and hence to stimulate economic growth. A liquidity trap is caused when people hoard cash because they expect an adverse event such as deflation, insufficient aggregate demand, or war. Signature characteristics of a liquidity trap are short-term interest rates that are near zero and fluctuations in the monetary base that fail to translate into fluctuations in general price levels.

Much the same furor has emerged in the United States and Europe in 2008–2010, as short-term policy rates for the various central banks have moved close to zero. Paul Krugman argued repeatedly in 2008-11 that much of the developed world, including the United States, Europe, and Japan, was in a liquidity trap.[2] He noted that tripling of the U.S. monetary base between 2008 and 2011 failed to produce any significant effect on U.S. domestic price indices or dollar-denominated commodity prices.
