I see a lot of emphasis on this thread on increasing the PD rate because overall accumulation of PD's will be faster. That benefit seems contentious enough.
What has not been emphasized, though, is the value of increasing the PD rate because of increased liquidity. This was a point that was...
Correct, but there will be an immediate effect due to the collective knowledge that PD's are more common as well as a delayed effect once the PD supply begins to normalize. Both will result in market corrections.
It's also a liquidity issue, which can be addressed by modifying the supply of the currency, or more precisely, the ratio of the currency supply to goods. The existence of stock splits has proven that this is an effective technique.
