This is all a sign that the paid-sex market has finally begun maturing in the Lower Mainland. A sign of a maturing market is when a group of products or services takes most of the share of the market, with new entries of products/services into the market place as fast as old products/services leaving, and prices stabilizing.
So applied to the paid sex market here, it means a few of the girls are making most of the money while the rest are making much less. The girls who make less compensate by i) offering the same level of service as the girls who make more, or ii) increase prices. It seems that they are increasing price more often because they don't want to stoop to the level of service being offered by those who have cornered the market. As for new entries into the market place, these are from craiglist entries and the influx of new illegal shops. The barriers to entry are none because there is little cost to be a craiglist entry or to set up an illegal shop. All these new entries have forced the existing service providers to a market price that is more or less consensual - around $140 for an AMP, $180 for an MP. The new entries have also forced some existing service providers out of the market, as evidenced by increasing retirements because it has become too competitive.
I think that the price is going to remain stable for some time at the rates I quoted above. Pooners who cry about high prices are complaining about the girls who have increased prices to compensate for decline of customers, or are simply unable to afford their uncontrollable impulses.
The girls who have increased prices to compensate for decline in customers have made the correct economic decision, in my opinion. They realise that there will always be a league of men who are interested in getting service from them and are willing to pay an increased price, who also find high-mileage asian providers not to their taste. The impact of a higher price on these girls has been less overall income, but probably not a lot less than what they had before. So guys, stop your whining or earn more money or control yourselves better.
The most exciting new thing for pooners in the market place has been the new craiglist entries and micros. Unless there is some kind of LE crackdown, this will continue for an unforeseen period. An LE crackdown will benefit the legal shops, and would be a god-send to them. It means prices can rise again in the MPs and the independants can more easily justify their new high prices while offering the same service.
