GoOD LucK!

Commissions are not set, but it's not hard to figure out what the averages are in any given market. And I'd never thought that "the BEST agents always show their buyers the houses with the higher commissions", I always thought that fell to the "easiest to buy-off agents". But I do recognize that MANY agents will show a listing because of the higher commission offered – for this reason, I do recommend a higher commission (my side stays the average) be offered to the buyer's agent when I take a listing.

On the flip-side, I've sold many good deals to my buyers because there was no competition for a house that offered a less than average commission. I made less on that kind of transaction, but all their friends and relatives want me as their Realtor later – so I make more for that transaction.

According to monetarist theory the inflation rate is equal to the Quantity of Money X Velocity

Velocity of money measures the rate at which the money circulates in the economy. Low demand or spending would imply a low velocity in the currency.

Therefore, in theory, a low velocity of money coupled with a relatively large quantity of money would equal about the same inflation rate as a high velocity with a smaller quantity of money.
For example, the Fed can expand the money supply by printing more dollars to make open market purchases, lowering the bank to bank lending, but if high money demand should persist, it would result in low velocity and the inflation rate wouldn't change much. This is why it's possible to increase the money supply to a large extent and still not see inflation.

I don't think monetary economists care as much about a constant velocity of money, as they do in the rate of change of the velocity of money in a given time period. A positive change signals healthy demand while a negative change signals deflation.

Anyhow, you sparked my interest in this Issue again and I'm going to do some more reading on it. By the way, here's a pretty good source below.
