”The U.S. government has a technology, called a printing press (or, today, its electronic equivalent), that allows it to produce as many U.S. dollars as it wishes at essentially no cost.”

What is interesting is that Bernanke in his speech presented a theoretical base for how the Fed would be able to stimulate the economy with interest rates at zero and that today interest rates in the U.S. and many other countries are precisely zero or near zero.
To see the relevance of this today and to see why it can be interesting to look closer at what Bernanke said in his speech let us take a closer look at what deflation and its effects really are. To use Bernanke's own words from 2002:
"Deflation is in almost all cases a side effect of a collapse of aggregate demand--a drop in spending so severe that producers must cut prices on an ongoing basis in order to find buyers…/…/the economic effects of a deflationary episode, for the most part, are similar to those of any other sharp decline in aggregate spending--namely, recession, rising unemployment, and financial stress."So, a sharp decline in demand which leads to deflation which then leads to recession, rising unemployment and financial troubles. Sounds familiar anyone?
Surely, the present crisis did not start because of deflation that was caused by a decline in aggregate demand, it happened because of bad loans in the financial sector. These loans have however led to a colapse in worldwide demand and that has in turn led to inflation turning negative in many parts of the world including Sweden, where inflation was -0,7 % in november, in other words; deflation. It has also led to rising unemployment, the worst recession since the WWII and global financial markets in crisis and interest rates close to or at zero. Although these current low interest rates are not a result of deflation but rather conscious decisions by central banks, they have however put many central banks including the Fed in the situation that Bernanke was discussing in his speech 2002, leaving them without their traditional weapon to stimulate the economy.
