Derivatives Arbitrage and Money From Thin Air

One of my favorite stories related to this topic:

You might even, as IMF economists Jaromir Benes and Michael Kumhof have been doing with their excellent working paper “The Chicago Plan Revisited” search for answers in the creative past and, with the benefit of modern technology, conclude that the time has come to end fractional-reserve banking once and for all....MORE
