The three theories differ concerning their explanation of where the money comes from when a bank extends a loan. Werner proved empirically that the money for a new loan is not transferred away from any other account inside or outside the bank. Instead, each bank has the power to create money newly. When we take out a loan from a bank, the money will be newly created and added to the money supply. This has important implications, which are shown in the Quantity Theory of Disaggregated Credit published earlier by Professor Werner.
